With ongoing talk that the next move by the Reserve Bank of Australia (RBA) could be upward, not downward, when it comes to interest rates, it’s more important than ever to understand how even small rate rises can immediately and significantly affect household borrowing capacity. Economists broadly agree that the cycle of further rate cuts is now over, and any future changes are more likely to be increases rather than decreases.
Why Small Rate Rises Have Big Consequences on Borrowing Power
When interest rates rise, ongoing mortgage costs increase because borrowers pay more interest on every dollar they owe. Lenders don’t just assess loans on current rates — they also apply serviceability buffers, meaning they test whether borrowers could continue to afford repayments if rates rose further. This protects both banks and borrowers, but it also exacerbates the impact of a rate rise on borrowing capacity.
Industry analysis shows that a 0.25% (25 basis point) rise in interest rates can reduce borrowing capacity by approximately $20,000–$30,000, depending on income, household expenses and lender criteria. While that might seem modest in isolation, these impacts can compound quickly as rates rise.
What This Means for a Household Earning $180,000
Let’s put this into context for a typical Melbourne household with a combined annual income of $180,000 looking to borrow around $750,000. At current borrowing conditions, a household at this income level may comfortably service that loan amount. But when interest rates rise:
- A 25-basis point increase can reduce borrowing capacity significantly, potentially by $20,000+ meaning you may suddenly no longer qualify for the $750,000 loan you planned on.
- After just four 0.25% increases (1%), the same household could see borrowing capacity reduced by $80,000–$120,000.
That’s the difference between qualifying for your preferred property such as a townhouse in Brunswick or a renovated home in Footscray and being priced out of the market or needing to compromise on location or size.
The Practical Impact on Buying vs. Renting in Melbourne’s Inner Suburbs
For many households, choosing to delay entering the property market isn’t just a passive choice, it has a real financial opportunity cost.
Take rental costs in the Inner West and Inner North:
- Footscray and Yarraville median weekly rents hover around $400+ per week for a typical property.
- Brunswick and surrounding inner suburbs commonly see rents in the $420–$550+ weekly range.
At $400/week, renting instead of buying for just 3 years would amount to:
$400 × 52 weeks × 3 years = $62,400 in rent paid from taxed dollar and money that builds no property equity over time.
Now imagine rents increasing over that same period. Recent data shows Melbourne rental prices have risen sharply in many suburbs, reflecting tight vacancy rates and strong demand.
Why Buying Now Might Be Smarter Than Waiting
1. Lock in borrowing capacity before further rate rises:
Every potential increase could erode how much you can borrow. Entering the market sooner helps secure loan capacity before that buffer gets smaller.
2. Build equity rather than pay rent:
While rent may feel like “just covering the cost of shelter,” buying means your repayments are building your asset & not your landlord’s.
3. Inner West and Inner North remain strong long-term markets:
These areas are highly desirable due to lifestyle amenities, transport access, schools and employment proximity traits that support long-term capital growth and rental demand.
4. Renting isn’t always cheaper:
Current rents in places like Footscray, Yarraville and Brunswick can equal 30–35% of a $180,000 income, with little left over for saving a larger deposit.
VIC continues to dominate submission volume and budget size. Buyers here are typically upgrading or moving into second-step homes rather than entering the market.
If we were to take Brunswick West as an example, the average search duration sits around 5–6 months, indicating active buyers who are engaged but weighing trade-offs between location, dwelling quality, and price. Budgets are materially higher than other states, with multiple searches extending well above $1.5m with pre-approved clients sitting at 58% across the state of Victoria.
Thomas Mifsud Buyers Agent Broker from Australia Leading Buyers Agent (ALBA) has created a calculator that highlights the cost of waiting to purchase, but it also highlights the importance of professional advice and understanding property cycles that often differs from suburb to suburb, not dissimilar to say BHP & Rio Tinto. Both are in the same industry, but their share price and outlook may differ greatly.
In the inner metro markets, suburbs like Essendon, Moonee Ponds, and Ascot Vale have been active, and during the September and December quarters of 2025, inner metro capital growth averaged 1% per calendar month. This demonstrates that real growth is achievable in rising markets, and the cost of waiting compounds over time, making timely action essential.

The calculator shifts the conversation from opinion to data.
While affordability often drives investor interest, affordability-led growth is typically short-term. Current indicators point to more subdued conditions over the next six months.
That’s why “growth suburbs” alone should never be the target. Success comes from understanding the market cycle, knowing where we are within it, and building strategies around timing, not headlines.
It’s worth noting that for stronger capital growth potential and better resilience when markets cool, the focus should always be on well-located, quality properties in established suburbs close to key amenities and major transport links. Houses, townhouses and low-density units consistently outperform in rising markets and tend to hold their value more effectively in downturns than high-rise apartments or older-style flats. While the 1% monthly gains seen during the September and December quarters were encouraging, they are unlikely to persist, and past performance should never be relied upon as an indicator of future returns. The most dependable strategy remains to buy the right asset in the right location, within your budget, and to hold it for the long term.
Why this matters for you
Many clients delay decisions in search of greater certainty. But in affordability-driven markets, hesitation is usually the most expensive choice.

The Bigger Picture: Market Dynamics vs Borrowing Reality
Over recent years, rate increases have transformed buyer capacity faster than prices have fallen (if at all) in many inner urban markets. That means buyers aren’t necessarily seeing cheaper properties, rather just more limited ability to borrow for them.
This disconnect between borrowing capacity and property pricing is particularly noticeable in inner-city markets like Melbourne’s Inner West and Inner North. While rents have surged and remain high, property prices have been resilient, leaving many renters asking, “Will I ever get into the market?” The most effective way to answer that is often by acting now with advice tailored to your financial position.
Every 0.25% shift matters when it comes to interest rates and borrowing capacity especially for households aiming to buy in sought-after parts of Melbourne like Footscray, Brunswick, Northcote and Yarraville.
