Planning with the result

A borrowing result is a planning boundary, not a permission slip. Keep room for insurance, council rates, strata, repairs, and rate movement before treating a property range as safe. Stamp duty and settlement costs reduce what you can commit to the purchase price — property budget is smaller than borrowing power once all upfront costs are included.

Stress-rate buffer

Lenders apply a 3% serviceability buffer above the actual rate. This calculator lets you set your own buffer to model conservative scenarios.

Deposit & LVR

A deposit below 20% typically requires lenders mortgage insurance (LMI), adding to upfront costs and reducing your net property budget.

Common questions
Is borrowing power the same as lender pre-approval?
No. Borrowing power is a planning estimate. Formal pre-approval also depends on lender policy, credit checks, and documentation.
Should I use maximum borrowing power as my budget?
Usually no. A safer range leaves room for rates, insurance, council, strata, and other housing costs.
Do I need stamp duty before trusting the result?
Yes. Property budget is smaller than borrowing power once stamp duty and settlement costs are included.
