What determines your borrowing capacity

Your borrowing limit depends on more than income it’s about overall financial health and risk. Key factors:

  • Income: Salary, bonuses and rental income form the base.

  • Debts: Credit cards, car loans and existing mortgages reduce capacity.

  • Living costs: Everyday expenses are closely assessed.

  • Interest buffer: Lenders test affordability at higher “assessment” rates.

A HeyNest broker analyses these factors across multiple lenders to show your true borrowing potential.

Frequently asked questions

Do borrowing power calculators give an exact amount?

No, they provide a strong estimate. The final loan amount is confirmed only after a full application and credit assessment by the lender.

Does my deposit size affect how much can I borrow?

It affects the Loan to Value Ratio (LVR) and whether you pay Lenders Mortgage Insurance (LMI), which can indirectly impact the final approved amount, but your income/expenses are the main drivers.

How long does a pre-approval last?

In Australia, pre-approvals typically last for 90 days. You will need to renew it if you haven't found a property within that timeframe.
