Q: How much should I borrow to buy a house?
A: We recommend spending no more than 25% to 30% of your monthly pre-tax income on your mortgage. For example, if you earn $80,000 a year, that's around $1,667 to $2,000 per month. This leaves you money for essential expenses and everyday items, such as living costs, house repairs and insurance, council rates bills, utilities and any body corporate charges.
