Conventional Mortgages Australia 2025: Rates, Requirements & Updates

Thinking about buying a home in 2025? Understanding conventional mortgages—and how new lending rules are changing the landscape—could be the key to getting your foot in the door.

What Is a Conventional Mortgage?

A conventional mortgage is a home loan that isn’t insured or guaranteed by the government. In Australia, this typically means a standard variable or fixed-rate home loan from a bank or credit union, as opposed to specialist loans like those for first-home buyers with government guarantees or low-deposit schemes. With property prices shifting and new regulations in play, conventional mortgages remain the backbone of Australian home lending.

2025 Lending Standards: What’s Changed?

Australia’s lending landscape has evolved in response to rising interest rates, inflationary pressures, and regulatory tightening. Here’s what’s new in 2025:

• Higher Serviceability Buffers: In early 2025, APRA (the Australian Prudential Regulation Authority) maintained its serviceability buffer at 3%, meaning lenders assess your ability to repay as if rates were 3% higher than the offered rate.

• Minimum Deposit Requirements: Most lenders now require at least a 20% deposit to avoid lenders mortgage insurance (LMI), although some banks offer 15% options with stricter criteria.

• Credit Assessment Scrutiny: Living expenses and discretionary spending are under closer review, with lenders asking for more documentation and using open banking data to verify applicant spending patterns.

These measures aim to protect borrowers from overextending themselves, but they can make securing a conventional mortgage more challenging—especially for first-home buyers or those with non-traditional income.

Rates, Fees & Features: 2025’s Conventional Mortgage Market

While the Reserve Bank of Australia (RBA) has kept the cash rate stable for much of 2025, mortgage rates remain higher than pre-2022 levels. Here’s a snapshot of what to expect:

• Interest Rates: Standard variable rates for conventional home loans are hovering around 6.1–6.6% p.a. in mid-2025. Fixed rates (3 years) average 6.3–6.8% p.a., though some lenders are offering sub-6% deals for high-quality borrowers.

• Fees: Upfront application fees range from $200–$700. Ongoing package fees (for offset accounts or bundled credit cards) can add $300–$400 per year.

• Offset & Redraw: Most conventional mortgages offer offset accounts or redraw facilities, which can help reduce interest paid over the life of the loan.

• Loan-to-Value Ratio (LVR): Lenders prefer LVRs of 80% or lower, but some will go higher with LMI. In 2025, LMI premiums have edged up, reflecting increased risk and inflation.

With more fintech lenders and digital banks entering the market, competition remains strong. Some lenders are offering cashback incentives—up to $4,000—to attract refinancers, but these deals often come with higher rates after the introductory period.

Who Should Consider a Conventional Mortgage?

Conventional mortgages are best suited to borrowers who:

• Have stable employment and income

• Can provide a 20% deposit (or more) to avoid LMI

• Meet standard lending criteria on serviceability and credit history

• Don’t qualify for government-backed schemes (like the First Home Guarantee)

Self-employed applicants or those with variable income may face extra hurdles—banks will often require two years of tax returns and additional documentation in 2025. However, if you tick the boxes, you’ll likely access better rates and more flexible features than specialist or government-assisted loans.

Case Study: Navigating a Conventional Mortgage in 2025

Consider Jane and Sam, a Sydney couple looking to buy their first home in the Inner West. They’ve saved a 20% deposit on an $850,000 property. With stable incomes and good credit, they secure a 30-year conventional mortgage at a 6.2% variable rate. Thanks to their offset account and careful budgeting, they plan to make extra repayments, aiming to shave years off their loan term.

By meeting the 20% deposit threshold, Jane and Sam avoid LMI—saving them around $14,000 upfront. Their lender’s digital platform makes it easy to track spending and make repayments, while competitive rates keep their monthly costs predictable.

The Bottom Line

Conventional mortgages remain the go-to option for many Australian homebuyers in 2025, offering flexibility and competitive rates for those who meet the criteria. With tighter lending standards and higher rates, preparation is key: focus on deposit savings, maintain a clean credit record, and compare lenders to find the best fit for your situation.
