Borrowing Power — Frequently Asked Questions
What determines how much I can borrow?
Lenders look at your income, living expenses, existing debts and credit commitments, the size of your deposit, and the interest rate. Together these decide your serviceability — how comfortably you can meet repayments.
Why do different lenders offer different borrowing amounts?
Each lender uses its own assessment criteria, expense benchmarks and “buffer” rates when testing your ability to repay. That’s why your borrowing power can vary significantly from one lender to the next.
How can I increase my borrowing power?
Reducing credit card limits and other debts, lowering discretionary spending, increasing your deposit, or adding a co-borrower can all help. A broker can show you which levers make the biggest difference for you.
Does the calculator guarantee I’ll be approved for that amount?
No — it’s an estimate only. Actual approval depends on a full lender assessment of your documents, credit history and the property. We can help you confirm a realistic figure before you make an offer.
How much deposit do I need?
Many lenders look for around 20% to avoid lenders mortgage insurance, but loans with smaller deposits are available. The right amount depends on your goals, the lender and your overall financial position.
