Same $150K household income. Up to $150K less borrowing power.
That’s how much it can change depending on who earns the money in your house. Most people only find out when they’re sitting across from a lender.
Banks don’t lend off your gross income. They look at what’s left after tax and living costs, and two adults cost more to run than one. If the whole $150K is on one payslip and your partner’s home with the kids, the gap gets bigger again.
And every bank does the maths differently. On the same dual income, ANZ took $89K off the borrowing power and Westpac took about $39K. That’s a $50K difference just from picking a different lender.
Save this if you’re planning to buy next year. And if you want your own numbers run properly, DM me “NUMBERS”.
