Is Your Rose Bay Home Loan Still Competitive? Do This One-Week Review

Most Rose Bay borrowers don’t realise their home loan has become uncompetitive until the pain shows up in their cash flow. By the time the RBA has nudged rates up a few times and your fixed term has rolled off, you might be quietly paying tens of thousands more than you need to.

A Rose Bay home loan is usually no longer competitive if your interest rate is roughly 0.50–1.00 percentage point or more above what a similar new borrower could get at your loan-to-value ratio (LVR), or if your structure and fees no longer suit how you actually use the property and your cash. The goal of this checklist is simple: give you a decision-grade answer this week – stay, sharpen or switch.

Let me walk you through how I’d review a typical Rose Bay loan for a busy professional couple or self‑employed client.

A quick annual check-in on your home loan can prevent silent cost creep.

1. Start with the only question that matters: what’s your real rate?

The mistake I see most is people comparing their rate to headlines, not to realistic new‑customer offers for their profile.

1.1 Pull your actual rate and basic details

In 10 minutes, you can collect what you need:

• Current interest rate(s) for each loan split
• Variable vs fixed; principal & interest (P&I) vs interest‑only (IO)
• Remaining term (e.g. 24 years)
• Balance on each split
• Property value estimate and LVR (balance ÷ value)

Don’t guess the rate. Log into internet banking or grab the most recent statement.

1.2 Benchmark against realistic new‑customer pricing

From there, you want to know: what would a new borrower, like me, realistically get today?

Factors that matter:

• LVR bands – ≤60%, ≤80%, >80% with LMI
• Purpose – owner‑occupied vs investment
• Repayments – P&I usually cheaper than IO
• Income type – PAYG vs self‑employed / complex

Indicatively, if new‑to‑bank owner‑occupied borrowers at your LVR are getting around X–Y% and you’re sitting X+0.7–1.0%, that’s a red flag. You don’t need exact numbers for this exercise – just know the gap. As I’ve written before, a practical indicator of an uncompetitive home loan is being roughly 0.50–1.00% above new‑customer rates for similar borrowers (see /insights/how-to-tell-if-your-home-loan-rate-is-uncompetitive-2026).

If you’re in that range, your next step is either:

1. Push your current bank for a repricing, or
2. Start a refinance comparison using a broker who understands large Eastern Suburbs loans.

2. Run the stress test: is the loan still safe for your income?

Rate competitiveness is only half the story. The other half is: can you comfortably carry this loan through the next cycle?

Roy Morgan’s latest data shows 28.2% of Australian mortgage holders are ‘At Risk’ of mortgage stress, with that number likely to rise if rates climb further. In practice, for high‑priced Eastern Suburbs properties, I like to keep total home and investment loan repayments below roughly 30–35% of net household income.

2.1 Calculate your real repayment ratio

Do this on a single page:

1. Add up all property debts – home and investments, across all banks.
2. Add the required minimum monthly repayments on P&I terms.
3. Divide by your after‑tax household income.

Example:

• Loans: $3.2m total (home + one investment)
• Required P&I repayments: say $18,500 per month at your current blended rate
• After‑tax income: $55,000 per month

Repayment ratio = $18,500 ÷ $55,000 ≈ 33.6%.

That’s at the top of the practical 30–35% band I use for Eastern Suburbs clients.

2.2 Stress-test 3% higher and an income shock

APRA expects banks to test your borrowing at least 3 percentage points above the actual rate. For large Eastern Suburbs mortgages of $2–5m, I recommend you do something similar: model repayments at +3% plus a 30–50% income shock.

Using the example above:

• Current blended rate: say 5.8% p.a.
• Stress rate: 8.8% p.a.
• New P&I repayments on $3.2m might jump to ~ $24,500 per month (illustrative only).

Now assume one partner’s bonus dries up and income drops 30% to $38,500 per month.

New ratio = $24,500 ÷ $38,500 ≈ 63.6%.

If that number makes your stomach flip, your loan is not in a safe position, even if the rate looks okay. You may need:

• A sharper rate to buy breathing space
• To restructure (e.g. convert some short‑term business or personal debt into a separate, shorter home loan split)
• A more conservative 10‑year plan (see /insights/long-term-property-mortgage-planning-eastern-suburbs)
