Self-Employed Mortgage Applications – The Complete New Zealand Guide
Our definitive guide to getting a mortgage when self-employed in New Zealand explains how banks calculate your income, why 20% deposits matter, how to avoid costly mistakes, and lists alternative lenders and a 90-day preparation timeline
Updated 21 August 2025
Summary
Our guide covers:
- Getting a mortgage when you're self-employed in New Zealand has, for many, been a difficult process. There is confusion, some suspicion, and lenders have different requirements.
- However, banks want to lend to successful business owners - they just need more convincing than they do with PAYE employees, who can show a couple of payslips and be offered a mortgage.
- Whether you're a contractor making six figures or running a growing business, securing home financing is achievable. But you need to understand how banks think, what they're looking for and make sure your application aligns with what lenders need to see.
- Our comprehensive guide reveals exactly how New Zealand banks evaluate self-employed mortgage applications. We'll show you why a $300,000 profit might only count as an income of $40,000 in the bank's eyes, and why timing your application wrong could cost you your dream home.
- Most importantly, our guide helps you avoid the expensive mistakes that sink self-employed applications - from mixed business structures to unexplained income variations.
- While banks require more paperwork from business owners, they're ultimately looking for the same thing as they do with any borrower - confidence that you'll pay them back.
- This is one of our most comprehensive guides - please read it at your own pace, and please email our research team if you have suggestions to improve it.

How Banks Really See Self-Employed Borrowers
When you walk into a bank as a self-employed borrower, you're immediately sorted into one of three buckets based on your business turnover. This isn't just filing - it fundamentally changes who assesses your application, what products you can access, and how much they'll understand your business.
Small Business: Under $500,000 TurnoverThis is where most contractors, freelancers, and side businesses land. If you're a plumber working for yourself, a marketing consultant, or running an online store, you're probably here.
Banks slot this segment as "higher risk" - not because you're unsuccessful, but because their models say smaller businesses have more variable income. Most self-employed business owners recognise this, so it's unsurprising that banks have a more rigid process to assess applications. The reality for your mortgage or business lending application:
Our View: It's frustrating because it's arguable that a self-employed electrician with fifteen years of consistent work probably has better job security than a middle manager at a small, mid-sized or large-sized business or government organisation. However, banks work on policies and probabilities, not common sense. |
Small to Medium Business: $500,000 - $3.5 Million TurnoverCross this magic threshold, and suddenly you're speaking to someone who understands why your profit dropped 30% ( Holding more stock because you have grown), but your sales increased. These business bankers typically manage 100-400 clients and understand cash flow, seasonal variations, and legitimate business expenses.
The mortgage application process is improved (compared to those falling into the 'Small Business' category). Applicants will usually receive:
|
Commercial Banking: Over $3.5 Million TurnoverThis is the "big league". Your relationship manager handles 40-100 clients and understands complex structures. They run annual risk assessments, but you also get access to pricing that will rival what retail customers are offered.
Your home loan becomes a small part of a relationship that might include GSA lending (unsecured), foreign exchange, and equipment finance. However, your business size doesn't determine if you can service a loan. It determines who decides and how well they understand your situation. |
The Two-Year Financial Statement Rule (And When to Ignore It)
Every self-employed mortgage applicant will be asked for "two years of financials". While this can seem invasive, it's all part of a bank's risk assessment. They want to see:
From their perspective, a PAYE employee proves stability with three months of identical payslips. Your business income tells a more complex story. This is your proof on how well you have done in business, and although it doesn't always tell a full story, it's the one that banks take notice of.
What if I have been in business for less than two years?
Know This: These exceptions need a compelling story and usually a mortgage broker who knows which banks have the appetite for your situation.
- Whether your income is trending up, down, or sideways
- How you handled economic rough patches
- If your busy season covers the quiet months
- Whether last year's great result was a fluke or a trend
From their perspective, a PAYE employee proves stability with three months of identical payslips. Your business income tells a more complex story. This is your proof on how well you have done in business, and although it doesn't always tell a full story, it's the one that banks take notice of.
What if I have been in business for less than two years?
- There are exemptions - our research process involved talking to highly regarded mortgage brokers who have overseen applications where only one year was required.
- Situations where this happened included when a self-employed applicant (in this case, a senior associate of a regional law firm earning $130,000) left to become a Barrister. After she went solo, she billed $160,000 in year one with $120,000 net profit (after deducting overhead expenses). Her lender took one year because she was doing identical work with proven demand.
- In another case, an applicant left corporate to consult for large companies and signed up for multi-year deals. With strong first-year results and signed contracts for year two, the lender approved the applicant after 12 months of trading.
Know This: These exceptions need a compelling story and usually a mortgage broker who knows which banks have the appetite for your situation.
How Banks Calculate Your Income
Warning: This can be a stressful time where you have no visibility, and the demands, process, and results can be confusing. For example, you may have made a net profit of $150,000 last year, but the bank will finalise your income at $72,000. It's important to understand what's happening and what you need to know.
Understanding the Add-Back Formula
Banks start with net profit before tax, then add back expenses that aren't real cash costs:
Tom's Landscaping example:
Why this looks mortgage application friendly and 'lendible', there are some things you need to know:
The Principal Payment Trap
Here's what catches everyone - banks add back interest but not principal payments on business loans. This destroys serviceability for asset-heavy businesses, making large capital repayments month after month. This is best explained in the example below.
Dave's Excavation business:
Dave thought he would have a strong application with a $400,000 income. However, the bank calculated $100,000 in actual free cash flow after accounting for the principal payments. This is why understanding their calculations before applying is crucial - the gap in this example between perception ($400,000) and reality ($100,000) is massive.
Understanding the Add-Back Formula
Banks start with net profit before tax, then add back expenses that aren't real cash costs:
- Depreciation: That $10,000 vehicle depreciation isn't cash leaving your account; it's accounting for the fact that in a few years, you'll need to replace the vehicle
- Interest paid: They'll calculate loan servicing separately
- Home office: Part of your existing home costs (e.g. overhead costs)
- Your wages: If you paid yourself a shareholder salary and/or director drawings (all with PAYE), it gets added back
- Any company income tax paid
- One-offs: Asset sale losses, bad debts, and anything else non-standard
Tom's Landscaping example:
- Net profit: $65,000
- Plus depreciation: $15,000
- Plus interest: $8,000
- Plus home office: $3,000
- Plus wages: $40,000
- Bank income: $131,000
Why this looks mortgage application friendly and 'lendible', there are some things you need to know:
The Principal Payment Trap
Here's what catches everyone - banks add back interest but not principal payments on business loans. This destroys serviceability for asset-heavy businesses, making large capital repayments month after month. This is best explained in the example below.
Dave's Excavation business:
- Net profit: $300,000
- Add-backs: $100,000 (includes $60,000 equipment interest)
- Bank calculated income: $400,000
- Total equipment payments: $360,000 ($60,000 interest + $300,000 principal)
- Since interest is already added back, only subtract principal: $300,000
- Actual surplus: $400,000 - $300,000 = $100,000
- The key insight remains the same - Dave thinks he's showing $400,000 to the bank, but after the principal payments, there's only $100,000 in actual free cash flow for servicing a new mortgage.
Dave thought he would have a strong application with a $400,000 income. However, the bank calculated $100,000 in actual free cash flow after accounting for the principal payments. This is why understanding their calculations before applying is crucial - the gap in this example between perception ($400,000) and reality ($100,000) is massive.
Understanding the Importance of Having a 20% Deposit
Banks offer a range of mortgage options, but a 20% deposit is where everything changes, and applications are a lot easier to get approved compared to a low-deposit mortgage.
With a 20% deposit or more, you escape Reserve Bank LVR restrictions. Banks don't like low-deposit loans as they're expensive to finance and riskier. If you have a deposit of 20% (or more), you're in the unrestricted pool, which means:
Many self-employed New Zealanders organise their deposit by:
With a 20% deposit or more, you escape Reserve Bank LVR restrictions. Banks don't like low-deposit loans as they're expensive to finance and riskier. If you have a deposit of 20% (or more), you're in the unrestricted pool, which means:
- Every bank can consider you
- There is more flexibility in income calculations
- You will be offered better rates and terms available
- There is more room to negotiate exceptions
- You will avoid mortgage insurance costs (which are charged on low deposit home loans by banks and Kainga Ora for a first home loan)
Many self-employed New Zealanders organise their deposit by:
- Working over the years to save 20% (a painful but powerful approach that relies on consistency), including voluntary contributions to Kiwisaver
- Using equity in other property to get there
- Timing applications when financials are the strongest
Working With Less Than a 20% Deposit
You won't be locked out if you don't have 20%, but you're playing by different rules, which adds cost and complexity.
Banks face hard limits (forced by law, and monitored by the Reserve Bank):
However, new builds are exempt from LVR restrictions. Banks can lend unlimited amounts for purchases from developers. This creates opportunities:
Banks face hard limits (forced by law, and monitored by the Reserve Bank):
- Maximum 20% of new lending to sub-20% deposit borrowers
- There is a lot of competition for the small number of low-deposit loans, and banks get extremely picky about who they approve
However, new builds are exempt from LVR restrictions. Banks can lend unlimited amounts for purchases from developers. This creates opportunities:
- More willing lenders for new builds
- Better terms despite lower deposit
- Developer incentives on top
- No fighting for restricted spots

Expensive Mistakes That See Lenders Reject Mortgages Applications
Here are five real mistakes we've seen cause issues for self-employed mortgage applicants:
The Timing Disaster
The Tax Minimisation Trap
The Unexplained Revenue Issue
Mixed Structure Problems
Challenges with Cash-Based Businesses
The Timing Disaster
- Error: Mark applied in April, right after his March year-end
- Why it's a problem: Banks wanted current financials, but his accountant needed until June to prepare them. Meanwhile, his dream house was sold to another buyer.
- Way to avoid it: Never apply in the "dead zone" between year-end and accounts completion unless you are well prepared The only solution here would have been for Mark to prep his accountant in March and have a Xero/MYOB profit and loss and trial balance sheet, and the previous year's results
The Tax Minimisation Trap
- Error: Sarah's accountant reduced her $400,000 revenue to $30,000 taxable profit through aggressive (legal) deductions
- Why it's a problem: Banks use profit as a starting point - no profit means no mortgage. Banks don't count the same way as the IRD does.
- Way to avoid it: If you're planning to buy property in the next 2-3 years, discuss this with your accountant. You might need to pay more tax to show a lendable income.
The Unexplained Revenue Issue
- Error: Tom's profits went $120,000 to $65,000 to $110,000 over three years without explanation
- Why it's a problem: Banks see unstable income and run away. Tom knew why (lost a major client, then rebuilt), but never documented it.
- Way to avoid it: Create a simple document explaining any profit variations over 20%. Include what happened, how you recovered, and why it won't happen again.
Mixed Structure Problems
- Error: Jane ran her consulting business and owned two rental properties through the same company
- Why it's a problem: Banks couldn't separate business income from rental income, making assessment nearly impossible. Different activities need different treatment.
- Way to avoid it: Keep clean structures - business separate from investments. Fix this before applying, or face weeks of confusion and impatient lenders who want to assess simpler applications.
Challenges with Cash-Based Businesses
- Error: Mike's cash-heavy café declared all income but couldn't prove it with bank deposits
- Why it's a problem: Banks worry about what they can't see. Even if you're 100% honest, cash businesses face extra scrutiny and often automatic declines.
- Way to avoid it: Meticulous record-keeping - every cash sale should match daily banking. Use point-of-sale systems that create audit trails. Consider moving to card-only before applying.
Making Banks Want Your Business
The best applications don't just tick boxes - they tell compelling stories.

Professional Presentation Matters
First impressions stick:

The fundamentals remain constant:
Our view: The lending landscape for the hundreds of thousands of self-employed New Zealanders looking to buy a home continues evolving. Banks are slowly improving at understanding business income, and alternative lenders are emerging. We believe the gap between employee and business owner treatment is narrowing.
Your business success should enable property ownership, not prevent it. With proper preparation, strategic timing, and possibly professional guidance, you can convert business profits into property assets.

Important: Getting a mortgage as a self-employed borrower isn't about pretending to be a PAYE employee - it's about presenting your business success in language banks understand.
The fundamentals remain constant:
- Preparation beats everything - don't delay gathering documents and working through what you need to provide
- Two years of history is standard, but can be flexible in certain cases - a mortgage broker will explain what you need to know
- A 20% deposit transforms your options - banks are far more willing to lend and the interest rates are better (all other things being equal)
- Business size affects who assesses you - the more revenue you generate, the more seriously you'll be taken, but a mortgage broker with self-employment application experience can be invaluable to guide you
- Income calculations follow predictable rules - make sure you understand them
- Timing can make or break applications - a bad patch of negative cash flow will overshadow earlier profits through poor bank account conduct or missed payments

When Professional Help Pays Off
For self-employed borrowers, the right mortgage broker can mean the difference between approval and decline.
The best mortgage brokers understand:
They translate between business reality and bank requirements, spot issues before they become declines, and know when to wait for better timing.
However, sometimes, especially with established business banking relationships, going directly to your existing bank makes sense. If your business banking manager understands your model deeply, you can leverage that relationship; however, there is less support offered during the process than what you'll find offered from a mortgage broker.
Our view: A DIY approach for anyone self-employed can cost more due to a few factors:
The best mortgage brokers understand:
- Which banks have an appetite for your industry
- How to present complex income stories
- Where flexibility exists in policies
- How to pre-solve problems

Our view: A DIY approach for anyone self-employed can cost more due to a few factors:
- Wrong bank selection - unless your business is an expert in self-employment mortgage loans, it's hard to know which lender(s) will work with your business
- Missed opportunities for better terms and structure - mortgage brokers know who offers the best deals for your situation, time and again we see banks charge more because it is a business loan backed by the family home or give you unsecured limits when it could be secured to lower the interest rate cost
- Months of delays from poor preparation - this costs you personal time, but can also negatively affect your business if you're distracted
Self-Employed Mortgage Checklist: Essential Documents
Getting your documents organised before meeting a mortgage broker or bank saves weeks of back-and-forth. Here's exactly what you'll need:
Financial Statements (Non-Negotiable)
Tax Documentation
Business Banking
Business Overview
Personal Documentation
If Applicable:
Know This: We suggest creating a PDF folder with everything scanned and clearly labelled. Banks lose documents with surprising frequency. Having digital copies ready means you can resend in minutes, not days.
Financial Statements (Non-Negotiable)
- Last 2 years of financial statements (year-end accounts)
- Must be prepared by an accountant (not DIY)
- Include profit & loss, balance sheet, and notes
- If year-end was recent, have draft accounts ready
Tax Documentation
- IR3 returns for the last 2 years (personal tax returns) (matching financial statements)
- IR7 partnership returns if applicable
- Current tax position (any debt or refunds due)
- GST returns if requested (some banks want these)
Business Banking
- 6 months of business bank statements (all accounts)
- 3 months of personal bank statements
- Loan statements for all business debt
- Credit card statements (business and personal)
Business Overview
- One-page business summary (what you do, how long, major clients)
- List of major contracts or recurring revenue
- Explanation of any profit variations over 20%
- Business structure diagram if your business is complex
Personal Documentation
- Photo ID (passport or driver's licence)
- Proof of address (utility bill or rates notice)
- Personal asset and liability statement
- KiwiSaver statements (if using for your deposit)
If Applicable:
- Shareholder/partnership agreements
- Trust deeds if the business operates through a trust
- Rental income statements for investment properties
- Separation agreement if recently separated
Know This: We suggest creating a PDF folder with everything scanned and clearly labelled. Banks lose documents with surprising frequency. Having digital copies ready means you can resend in minutes, not days.
Alternative Lenders: When Banks Say No
Traditional banks aren't your only option. Non-bank lenders have emerged as genuine alternatives for self-employed borrowers who don't fit the arguably rigid bank criteria. We list professional lenders with different risk appetites:
When alternative lenders can make sense:
Know This: The interest rates will almost certainly be higher - typically 1.5-3% p.a. above bank rates. On a $500,000 mortgage, that's $5,000-15,000 extra per year. But consider the cost of the alternatives:
Smart borrowers use non-bank lenders as stepping stones:
Many succeed with this approach, but factor in the higher costs into your planning and have a clear path back to mainstream mortgage lending.
- Pepper Money: Specialists in "near prime" lending, and reader reports suggest they will consider applications with one year's financials
- Liberty: A long-standing non-bank lender with similar options to Pepper Money, as well as "no doc" loans
- Avanti Finance: Popular for complex income situations, as outlined in this case study
- Basecorp - longer-term product provider and provides commercial lending
When alternative lenders can make sense:
- If you have only one year in business, but can show strong income
- You experienced a recent bad year affecting your average
- You have a complex structure, banks won't assess
- You need money fast (settlements in 2-3 weeks)
- You have credit issues from business challenges
Know This: The interest rates will almost certainly be higher - typically 1.5-3% p.a. above bank rates. On a $500,000 mortgage, that's $5,000-15,000 extra per year. But consider the cost of the alternatives:
- Missing out on your property
- Waiting another year to reapply
- Losing a business opportunity
- Paying rent while building perfect financials
Smart borrowers use non-bank lenders as stepping stones:
- They secure the property with alternative lending
- While repaying the mortgage, they build strong business financials for 1-2 years
- They then refinance with a main bank at better rates
Many succeed with this approach, but factor in the higher costs into your planning and have a clear path back to mainstream mortgage lending.
Self-Employed Without an Accountant? Will IR3 be Enough to Get a Mortgage?
This is a common question. The answer is complicated, and your success depends on many factors, as we outline below.
Banks want:
What Your IR3 Shows vs What Banks Need
Your IR3 contains:
But banks usually also need:
We believe the best approach is to speak to a mortgage broker. They will then explain if you need documents beyond IR3. If you do, your options include:
Option 1: Get Basic Accounts Prepared (Best)
Option 2: Non-Bank Lenders
Option 3: Find a Mortgage broker
Making DIY Financials More Credible
If you must go without an accountant:
Know This: Saving $1,000 on accounting fees could cost you:
Our View: While technically possible to get a mortgage with just an IR3, it's like representing yourself in court - legally allowed but rarely wise. The $1,000 spent on basic accounts typically returns much more with lower interest rates and actual approvals. If cash flow is tight, many accountants offer payment plans or will prepare basic mortgage-focused accounts at a reduced rate.
Banks want:
- Professional accountability (accountant's reputation on the line)
- Proper accounting standards applied
- Someone to call if questions arise
- Reduced risk of errors or optimistic calculations
What Your IR3 Shows vs What Banks Need
Your IR3 contains:
- Total income declared
- Expenses claimed
- Tax paid
- Basic profit/loss as a PAYE payer
But banks usually also need:
- Balance sheet (assets and liabilities)
- Detailed profit and loss breakdown
- Notes explaining unusual items
- Depreciation schedules
- Add-back calculations
We believe the best approach is to speak to a mortgage broker. They will then explain if you need documents beyond IR3. If you do, your options include:
Option 1: Get Basic Accounts Prepared (Best)
- Cost: $500-1,500 for simple accounts
- Many accountants offer "mortgage-ready" packages
- Can work from your existing records
- Transforms your application success rate
- Tax bonus: might find deductions you missed
Option 2: Non-Bank Lenders
- Pepper Money, Liberty, Avanti Finance and Basecorp can accept IR3s and GST returns
- Will likely charge higher rates (1.5-3% p.a. extra)
- You may see it as temporary until you get accounts done if you want to move fast into home ownership, and you can refinance once you have proper financials
Option 3: Find a Mortgage broker
- Some mortgage brokers have individual relationships with flexible lenders, like new entrants or local building societies
- Might know which banks are hungry for business
- Can present your story optimally
- Still recommend getting accounts for year 2
Making DIY Financials More Credible
If you must go without an accountant:
- Use accounting software (Xero/MYOB), not Excel
- Reconcile every transaction
- Separate business/personal completely
- Create professional-looking reports
- Document your methodology
- Explain every unusual item
Know This: Saving $1,000 on accounting fees could cost you:
- 0.5-1% higher interest rate = $2,500-5,000/year extra
- Declined applications damage credit score
- Missing out on properties while fixing paperwork
- Stress and delays are worth more than money
Our View: While technically possible to get a mortgage with just an IR3, it's like representing yourself in court - legally allowed but rarely wise. The $1,000 spent on basic accounts typically returns much more with lower interest rates and actual approvals. If cash flow is tight, many accountants offer payment plans or will prepare basic mortgage-focused accounts at a reduced rate.
The Real Cost of Low Deposit Mortgages for Self-Employed Business Owners
Everyone knows low deposits mean higher costs, but for self-employed borrowers, the premium can mean higher costs. Here's what you're looking at:
Interest Rate Examples
1) With a 20% deposit:
2) With a 5% or 10% deposit:
Real Dollar Impact:
For a $600,000 property purchase:
Plus with low deposit:
The Compound Effect: That extra $625/month could have been:
Strategic Alternative: Many self-employed borrowers find success by:
The calculation often works better than saving 20% while paying rent and watching prices rise.
Interest Rate Examples
1) With a 20% deposit:
- Main banks: 4.89% (1-year fixed)
- Negotiation is possible based on the business relationship
- Access to cashback offers (0.85% to 1.00% of the loan, with a first home buyer minimum of $5k with a loan over $250k)
- Choice of any bank
2) With a 5% or 10% deposit:
- Main banks: 1 year fixed 5.55% - 6.39%% (if they'll even look at you)
- Low equity premium: 0.35% - 1.50% extra added to the base loan OR
- Low equity fee of 0.35% to 1.00% of the loan amount, which can be capitalised to the loan amount (different banks either have a fee or add a margin/premium as above)
- First Home Loan: 1.20% insurance premium, which can be capitalised to the loan amount
- Limited bank options
Real Dollar Impact:
For a $600,000 property purchase:
- 20% deposit: $120,000 down, $480,000 mortgage at 6.00% = $2,877/month
- 10% deposit: $60,000 down, $540,000 mortgage at 6.75% = $3,502/month
- Monthly difference: $625
- Annual difference: $7,500
Plus with low deposit:
- $7,128 insurance premium (1.20% on First Home Loan)
- No cashback (missing out on ~$3,000)
- Higher legal/valuation costs
- Stricter income assessment
The Compound Effect: That extra $625/month could have been:
- Principal repayments (paying off the mortgage 5 years faster)
- Business investment generating returns
- Emergency fund for income volatility
- Capital for equipment or growth
Strategic Alternative: Many self-employed borrowers find success by:
- Buying investment property first (often easier approval)
- Living in it initially (avoiding investor restrictions)
- Using equity growth to fund an owner-occupied purchase
- Or keeping it as a rental and using equity for a home deposit
The calculation often works better than saving 20% while paying rent and watching prices rise.

Frequently Asked Questions
I've been self-employed for 18 months and am doing very well - why do banks still want two years?
Banks are pessimistic and don't like risk - they need proof to ensure it's not "beginner's luck" or a one-off. That said, if you're doing the same work you did as an employee (like a plumber who went solo), many banks will consider one year. The key is showing continuity, not just success. A good mortgage broker knows which banks flex on this rule.
My accountant is brilliant at reducing my tax to almost nothing - is this a problem for mortgage applications?
It often is - you can't have minimal tax and maximum borrowing capacity. If you've been aggressively minimising tax, you might need to "normalise" your accounts for 1-2 years before applying - this means paying more tax. You'll need to have an honest conversation with your accountant about balancing tax efficiency with lending requirements.
Banks calculated my income at $70,000, but I know I made $150,000 - what's going on?
These are the results of the add-back calculation. Banks start with your net profit, add some things back (depreciation, interest), but ignore others (principal payments on loans). That $80,000 difference is probably sitting in equipment loans, drawings not shown as wages, or legitimate business expenses that banks don't recognise. Understanding their formula before applying helps avoid nasty surprises.
Should I put my business and rental properties in the same entity to make it simpler?
This is usually unwise - banks need to assess business risk separately from investment returns. Mixed structures create assessment complications and often lead to straight declines. You'll likely want to keep them separate, even if it costs more in accounting fees.
I'm showing a loss this year, but have $200,000 in the business bank account - will banks care?
Banks care about sustainable income, not bank balances. That $200,000 could be gone tomorrow; they want to see consistent profits that prove you can handle repayments for 30 years. If this year's a write-off, consider waiting until next year's results show recovery. Or find a bank that will look at previous years more favourably.
My income varies wildly - last year $180,000+, this year might be closer to $80,000. How do I handle this?
Document everything. Banks hate surprises but can handle explanations. Create a simple sheet showing:
Some banks will use averages, others focus on worst-case scenarios. A mortgage broker can match you to the right approach.
- Why income varies (seasonal work, project-based, economic cycles),
- Your average over 3-5 years, and
- How you manage cash flow during slow periods
Some banks will use averages, others focus on worst-case scenarios. A mortgage broker can match you to the right approach.
Is it worth using a mortgage broker or should I go directly to my business bank?
We believe a mortgage broker who specialises (or has expertise) in self-employed applications is a valuable asset. They know which banks are hungry for business lending, who's flexible on requirements, and how to present your story. The best brokers get paid by the bank, not you, so there's no direct cost most of the time. It is best to check with the broker upfront, as some banks pay no commission on business-related loans, like unsecured or commercial lending
What's the biggest mistake self-employed borrowers make?
Waiting too long to start preparing, and after that, trying to hide things, delaying preparation and withholding information. Banks thoroughly review all provided documentation - it's better to be upfront about a bad year, the tax debt you're paying off, or why you changed accountants three times. Transparency with good explanations beats perfect records with surprises.
Can I include my partner's PAYE income with my business income?
Yes, and this often saves the day. Banks like the stability of PAYE income combined with the upside of business income. Just prepare for different requirements - your partner needs payslips and a letter from their employer, you need the full business documentation circus. The combination often unlocks better rates and higher lending.
I'm buying with a business partner - does this complicate things?
Yes - banks need to assess both businesses separately, understand the partnership structure, and consider the implications of the partnership ending. Get your partnership agreement sorted first, showing how property would be handled in a split. Some banks won't accept business partner purchase applications, while others are more willing. To gain a better understanding, we suggest working with an experienced mortgage broker.
