AXTON Finance holds multiple industry awards for mortgage broking. We handle loans for professionals and investors across Prahran who need clarity on whether their current rate still makes sense.

What Makes an Interest Rate High?

Your rate is high if it sits more than 0.30% above what you could access elsewhere on the same loan type and structure. That difference costs real money. Consider a borrower with a $700,000 variable rate home loan paying 6.50% when comparable products sit at 6.15%. That 0.35% gap adds roughly $200 per month to repayments. Over five years, that's $12,000 in avoidable interest. The comparison rate gives you a clearer picture because it includes most fees, but you still need to check what's actually available to you based on your deposit, income, and loan purpose.

In our experience, borrowers in Prahran often hold legacy products from lenders who reward new customers and overlook existing ones. A variable rate above 6.40% on an owner-occupied loan with a loan-to-value ratio under 80% usually signals room to move. Rates shift constantly, so static thresholds don't help. What matters is the gap between what you pay and what you qualify for today.

How to Compare Your Rate Against the Market

Start by identifying your loan type: variable or fixed, owner-occupied or investment, principal and interest or interest-only. Then check the comparison rate on products that match. The Australian Securities and Investments Commission publishes a Moneysmart comparison tool, though it won't reflect every lender or product. Speaking with a broker gives you access to a broader panel and pricing that isn't advertised publicly.

Consider a Prahran-based investor holding a $900,000 variable rate investment loan at 6.75%. That rate might have been competitive two years ago, but if current market pricing for the same structure sits closer to 6.35%, the borrower is paying an extra $3,600 annually. Running a loan health check clarifies where you stand without needing to lodge a formal application. Most lenders also offer rate discounts to new customers that don't flow through to existing borrowers unless requested.

Fixed Rate Break Costs and When They Matter

If you're locked into a fixed rate, your ability to refinance to reduce your rate depends on the break cost. Lenders calculate this based on the difference between your fixed rate and the wholesale rate they can now lend at for the remaining fixed period. If rates have risen since you fixed, the break cost is usually zero or minimal. If rates have fallen, the cost can run into thousands.

A Prahran borrower fixed at 2.89% for four years in late 2021 would face a substantial break cost to exit early, even if variable rates now sit above that fixed rate. The lender lost the benefit of that low fixed rate when wholesale funding costs climbed, and they recover that loss through the break fee. You need the exact calculation from your current lender before deciding whether switching makes sense. In some cases, the long-term savings from a lower rate outweigh the upfront cost. In others, waiting until the fixed term ends delivers a clearer outcome.

What Happens When You Don't Act

Staying on a high rate doesn't just cost you in direct repayments. It extends the time it takes to pay down your loan and reduces the equity you build in the property. On a $600,000 loan at 6.60% compared to 6.20%, the difference over ten years is roughly $14,000 in additional interest, assuming no other changes to the loan. That figure grows if you're also paying a higher monthly amount and not redirecting the savings into offset or extra repayments.

Prahran's median property values have remained firm, which means many borrowers hold significant equity. That equity can be released or preserved depending on how your loan is structured. A rate that's even moderately inflated erodes that position over time. We regularly see this with clients who refinanced from a major bank to a smaller lender or non-bank and immediately reduced their rate by 0.40% to 0.60% without changing their loan features or flexibility.

The Role of Loan Features in Rate Comparison

A lower rate isn't always the right move if it strips out features you rely on. Offset accounts, redraw facilities, and the ability to make extra repayments without penalty all add value. Some lenders offer rock-bottom rates on basic variable products with no offset and limited flexibility. Others price slightly higher but include full offset, portability, and split loan options.

For a professional in Prahran earning a variable income, an offset account can deliver tax-effective savings that rival a rate reduction. If your current loan includes these features and you're comparing against a product that doesn't, adjust your assessment accordingly. The comparison rate helps here, but it won't capture the value of an offset if you keep a high balance in it. If your rate is high and your loan lacks features, that's a clear signal to reassess. If your rate is slightly above market but your loan structure works well, the case for moving is less obvious.

When Refinancing Makes Sense

Refinancing typically makes sense when the rate saving covers the cost of switching within 12 to 18 months. Discharge fees from your current lender, application fees with the new lender, and valuation costs usually total between $800 and $1,500. If you save $150 per month by reducing your rate by 0.35%, you recover those costs in ten months. Beyond that point, the saving is pure gain.

We work with clients across Prahran who refinance not only to reduce their rate but also to access equity for renovations, investment deposits, or debt consolidation. The suburbs's proximity to Chapel Street, the Prahran Market, and the CBD makes it a tightly held area with strong capital growth. If your property has increased in value and your loan-to-value ratio has dropped, you may now qualify for a lower rate band than when you first borrowed. That shift alone can justify a refinance, even if market rates haven't moved significantly.

Frequently Asked Questions

How do I know if my home loan interest rate is too high?

Your rate is likely too high if it sits more than 0.30% above comparable products available to you today on the same loan type and structure. Check the comparison rate on similar loans and consider your loan-to-value ratio, as this affects the rate you qualify for.

What is a break cost on a fixed rate home loan?

A break cost is a fee charged by your lender if you exit a fixed rate loan early. It's calculated based on the difference between your fixed rate and the current wholesale rate the lender can lend at for the remaining fixed period. If rates have risen since you fixed, the break cost is usually zero or minimal.

When does refinancing to reduce my rate make financial sense?

Refinancing makes sense when the monthly saving from a lower rate covers the cost of switching within 12 to 18 months. Typical switching costs range from $800 to $1,500, so if you save $150 per month, you recover those costs in about ten months.

Should I refinance if my loan has features I rely on?

Not necessarily. A lower rate on a basic product without offset or redraw may cost you more in lost flexibility than you save in interest. Compare the value of your current loan features against the rate saving before deciding to switch.

Can I get a lower rate if my property has increased in value?

Yes. If your property value has risen and your loan-to-value ratio has dropped, you may now qualify for a lower rate band than when you first borrowed. This can justify a refinance even if market rates haven't changed significantly.
