How Much Can You Really Borrow in Melbourne in 2026 After the RBA Rate Rise?

Following the RBA's cash rate increase to 4.10% in March 2026, a Melbourne borrower on an average income can expect their borrowing capacity to have fallen by roughly 25–30% compared to 2021 peak conditions. The combination of higher variable rates, APRA's 3% serviceability buffer, and tightening debt-to-income scrutiny means the gap between what buyers feel they can afford and what lenders will approve has rarely been wider. Understanding the mechanics — not just the headline rate — is what separates a confident buyer from one chasing properties 15% above their true ceiling.

What the RBA's March 2026 Rate Rise Actually Means for Melbourne Borrowers

The Reserve Bank of Australia cash rate decisions lifted the official cash rate to 4.10% in March 2026, with major lenders including NAB passing on the full 0.25% increase to variable rate customers. Most standard variable home loans now sit in the 6.30–6.70% range depending on lender, loan-to-value ratio, and whether the loan is owner-occupied or investment.

For a borrower with an existing $600,000 variable mortgage, that 0.25% increase adds approximately $93 per month to repayments — roughly $1,115 per year. Across the full rate tightening cycle since May 2022, a borrower who took out a $700,000 loan at 2.10% is now servicing the same balance at rates more than four percentage points higher, representing an additional $1,900–$2,100 per month in repayments compared to their original schedule.

How APRA's Serviceability Buffer Caps Borrowing Power

The Australian Prudential Regulation Authority (APRA) serviceability guidance requires lenders to assess all new borrowers at their actual loan rate plus a 3% buffer. With variable rates currently around 6.50%, assessments are being run at approximately 9.50%. This is the single biggest constraint on borrowing power in 2026 — not the rate itself, but the stress-test rate built on top of it.

Illustrative example only:

A Melbourne household earning a combined $160,000 gross per year, with no existing debts, could have borrowed approximately $950,000–$980,000 in early 2021 when assessment rates sat near 5.5%. At today's assessment rate of ~9.50%, the same household qualifies for approximately $680,000–$720,000 — a reduction of $250,000–$280,000 on the same income.

That gap is the difference between a two-bedroom apartment in Preston and a house in the same suburb. It explains why many buyers pre-approved during 2021–22 are finding their finance no longer stretches to the properties they originally targeted.

The 30% Rule, Melbourne Prices, and What the Numbers Actually Show

The commonly cited guideline — keep housing costs below 30% of gross income — remains a useful starting reference, and is reflected in housing stress measures used by the Australian Bureau of Statistics housing affordability indicators, though it interacts differently at Melbourne's price points than in lower-cost markets.

For a single income earner on $95,000 gross (approximately $73,500 net), 30% of gross income is $28,500 per year, or $2,375 per month. At a 6.55% variable rate, $2,375 per month services a loan of roughly $390,000 on a 30-year principal and interest term. In Melbourne's middle-ring suburbs, where median house prices sit in the $850,000–$1,100,000 range, this points to a minimum deposit of $460,000–$710,000 to remain within the 30% threshold — illustrating why dual incomes have become near-essential for house purchases in most metropolitan zones.

At the household income level of $160,000, the 30% threshold rises to approximately $4,000 per month, servicing a loan of around $640,000 — broadly consistent with APRA's approved limit, which itself signals how tight the buffer has become at current rates.

Should Melbourne Borrowers Fix Their Rate in 2026?

The fix-versus-variable question depends on rate expectations, personal cash flow certainty, and flexibility needs. At current pricing, major bank fixed rates for two- and three-year terms are sitting broadly in line with or slightly above variable rates, suggesting lenders do not expect significant cuts in the near term.

Fixing provides repayment certainty, which matters for households already at the edge of the 30% threshold. The trade-off is that fixed loans typically restrict additional repayments and redraw access, and break costs apply if the loan is discharged early — relevant for buyers who may need to sell or refinance within the fixed term. A split loan structure — fixing 60–70% while keeping the remainder variable — is commonly used to balance certainty with flexibility.

The RBA’s forward guidance and commentary in its Statement on Monetary Policy as of early 2026 does not signal imminent cuts, and market pricing reflects rate reductions beginning late 2026 at the earliest. Borrowers fixing now are essentially paying for certainty, not for a lower rate.

How a Buyer's Agent Can Help Calibrate the Real Budget

Agencies like Forge Real Estate approach buyer mandates by anchoring the search to a stress-tested finance scenario before any property is inspected. Working alongside mortgage brokers, Forge models borrowing capacity under current assessment rates, then applies a further 0.50% upward stress test to identify a bid ceiling that holds even if rates rise again before settlement.

This approach — running suburb and property-type comparisons against a verified finance range — helps buyers pivot between dwelling types, locations, and loan structures rather than stretching emotionally at auction. For investors, Forge also models principal and interest versus interest-only structures across specific Melbourne assets, showing how repayment type affects cashflow at current rates and across plausible rate scenarios over a three-to-five year hold.

For buyers planning longer-term occupancy or rental, factoring in accessibility and future-proofing costs is increasingly relevant — particularly with ageing demographics. Engaging specialists in home accessibility modifications can help ensure properties remain suitable over time without requiring costly retrofits later.
