If you own property in Sydney or you’re thinking about buying your first investment property, you’ve probably spent some time comparing rates online. Maybe you found something on Canstar or called your existing bank. And maybe — just maybe — your bank came back with a rate starting with a 6.
Here’s the thing: that 6-something rate might be costing you more than you realise.
In 2026, the gap between what the big four banks offer investors and what’s available through non-bank and second-tier lenders has widened significantly. We’re talking the difference between 6.60% and 5.94% on a $900,000 investment loan — which works out to roughly $5,940 a year. That’s a holiday. That’s your strata fees. That’s meaningful cash flow on a negatively geared property.
What the Market Actually Looks Like Right Now
The RBA cash rate has been sitting at 4.35%, and lenders are pricing investment loans with a noticeable spread over owner-occupier rates. Variable investment loans (principal and interest) through competitive non-bank lenders are starting around 5.94% to 6.20% p.a. The major banks? More like 6.45% to 6.70% p.a.
If you’re on interest-only — which many Sydney investors use to manage cash flow on negatively geared properties — add another 0.30% to 0.50% on top of that. So you could be looking at 7.10% or higher if you walked into a branch and just signed whatever they put in front of you.
The other thing worth knowing: APRA requires lenders to test your ability to repay at your actual rate plus a 3% serviceability buffer. That means you’re assessed as if you’re borrowing at 9% or higher. Getting this buffer applied in a way that works in your favour — using a lender with a more generous rental income policy, for example — can mean the difference between approval and a decline.
A Real Scenario: The Neutrals Bay Investors
Take a couple in Neutrals Bay. Combined income around $280,000. They own their home outright (no mortgage), and they want to buy an investment unit in Marrickville for $850,000. They’d been with CommBank for 12 years and assumed they’d just use them for the investment loan too.
CommBank offered them a variable investment loan at 6.54% interest-only for five years. Monthly repayment: $4,631. Manageable, but tight after accounting for strata, council rates, and property management fees.
We came back with a non-bank lender at 6.09% interest-only. Monthly repayment: $4,314. That’s $317 a month back in their pocket — or $3,804 a year. Over a five-year interest-only period, that’s nearly $19,000 they kept.
There was a structural issue too. CommBank wanted to cross-collateralise their home as security for the investment loan. That’s a problem if they ever want to access their home equity independently or sell one property without the other. We structured the investment loan to stand alone, which gave them the flexibility to grow their portfolio later without needing to go back to the same bank every time.
Why Loyalty Doesn’t Pay — Literally
Banks price for risk and profit, and your years of loyalty don’t move the needle much. If anything, your existing bank often charges you more because they know switching feels like effort. That’s the loyalty tax, and it’s very real.
A broker’s job is to go across 30 to 40 lenders — major banks, non-banks, credit unions, and specialist lenders — and find the one that prices your specific scenario best. Not just the rate, but the whole structure: how a lender treats rental income in their serviceability calculations (some shade it by 30%, others by only 10%), whether they allow multiple offset accounts, how they handle negative gearing, and whether they’ll lend to a trust or SMSF if that’s the direction you’re heading.
These structural differences can have a bigger impact on your borrowing capacity than the rate itself. We’ve had clients who were declined by one lender and approved — same income, same loan, same property — by another, simply because of how that second lender assessed their rental income.
More Scenarios Where Structure Matters
Adding a second investment property: APRA’s debt-to-income cap of 6x gross income is starting to bite harder in 2026. If your combined household income is $200,000, your maximum total debt across all loans sits at $1.2 million — including your owner-occupier mortgage. The order in which you structure those loans, and which lenders hold each one, can mean fitting under that cap or being told no.
Releasing equity without cross-collateralisation: If your Sydney property has grown significantly in value, you may have $300,000 to $400,000 in usable equity sitting there. A broker can release that through a standalone equity loan against your home only — separate from your investment loan — so you avoid tying everything to one bank. Cleaner for tax purposes. Cleaner if your situation changes.
Switching from interest-only to principal and interest: With rates where they are, a lot of investors are reassessing. P&I rates are typically 0.30% to 0.50% lower, and the forced repayments chip away at your outstanding balance — which matters in a flat or declining market. Sometimes the right move is to refinance to a lower-rate P&I loan, especially if rents have risen to the point where your cash flow can absorb it.
The Bottom Line
Sydney investment property lending in 2026 is more complicated than it was five years ago. More lenders, more policy variation, stricter buffers, and more at stake in how you structure everything from the beginning.
Going direct to your bank isn’t necessarily wrong — but you won’t know whether you got a good deal unless you’ve compared it against the broader market. By the time the loan settles and you find out what you missed, it’s too late to change it without refinancing costs.
