Who qualifies for the best home loan interest rates?

Lenders price risk, not just borrowers, so the sharpest rate goes to whoever represents the lowest risk on paper: a large deposit, a loan for your own home rather than an investment, principal and interest repayments, and serviceable income relative to your existing debt. A lower loan to value ratio is one of the biggest single levers, since a bigger deposit relative to the property value moves a borrower into a materially sharper pricing tier; check the live comparison table for current verified rates at your own loan to value ratio.

Does your deposit size decide the rate you qualify for?

Loan to value ratio is one of the biggest levers a borrower controls. A bigger deposit relative to the property value can move you into a sharper pricing tier, and the jump often happens at thresholds such as 80% and 90%, where Lenders Mortgage Insurance and product availability also change.

Above 80% loan to value, most lenders also require lender's mortgage insurance on top of the higher rate, so the gap between an 80% and a 95% deposit is bigger than the headline rate difference alone suggests.

Do investors qualify for the same rates as owner-occupiers?

Usually not. Lenders price investment lending separately from owner-occupier lending, and APRA's macroprudential settings apply separate portfolio limits to each. Compare the current verified owner-occupier and investor cohorts at the same LVR and repayment type rather than carrying one headline rate across both purposes.

Does interest-only cost more than principal and interest?

Often, on both the rate and the total interest paid. An interest-only loan does not reduce the balance during the interest-only period, so lenders can price in the slower repayment and the balance remains higher for longer. Compare current verified principal-and-interest and interest-only rows at the same LVR before modelling the total cost.

Does your income and existing debt affect the rate you're offered?

Every lender assesses serviceability, whether you can afford the repayments at your rate plus a buffer, before quoting a final rate, and APRA's debt-to-income cap adds a portfolio-wide constraint on top: since 1 February 2026, authorised deposit-taking institutions must keep new lending to borrowers with a debt-to-income ratio of six times income or more under a 20% ceiling, tracked separately for owner-occupier and investor lending each quarter. A borrower who sits comfortably under that ratio, with a stable income history and manageable existing debt, is the profile a lender's own credit and pricing teams treat as lowest-risk, and lowest-risk is where the sharpest rates sit.

Do professional packages or existing customers get sharper deals?

Package loans, often bundling an offset account, credit card, and rate discount for an annual fee, can undercut a lender's basic variable rate for borrowers who use the features, and some lenders offer a further discount to doctors, accountants, and other professions with a lower assessed default risk. Existing customers rarely get a better rate automatically just for loyalty. Front-book pricing (the rate offered to new customers) is typically sharper than back-book pricing (the rate an existing borrower is quietly left on), which is exactly why comparing the whole market periodically, not just what your own bank currently offers, is part of qualifying for the best rate available to you.

Comparing your own bank's front-book pricing against the rest of the panel is worth doing directly, starting with BankSA's current rates. Another regularly competitive option outside the big four is Suncorp Bank's current rates. And for a lender known for sharp owner-occupier pricing, see Macquarie Bank's current rates.
