So you’ve found a property. Maybe it’s a two-bedder in Strathfield. Maybe it’s a townhouse in Penrith you’re eyeing for rental yield. Either way, you’ve done the mental maths, you think the numbers stack up, and now you need to figure out the finance.
Here’s where most Sydney investors hit their first wall.
They walk into their bank — the same one they’ve banked with for 20 years — and get told they can borrow $680,000. End of conversation. No explanation of why, no exploration of alternatives, just a figure stamped on a form and a handshake.
What they don’t know is that another lender — one the bank will never mention — might approve them for $820,000 at a lower rate, with an offset account and interest-only for the first five years.
That’s the difference a broker makes.
How Investment Loans Actually Work
Investment property loans in Sydney are assessed differently to owner-occupier loans. Lenders apply a loading to the interest rate when they stress-test your borrowing capacity — typically 3% above the actual rate. So if the loan is at 6.2%, they’re testing it at 9.2%.
That stress-test figure is what determines your maximum borrowing capacity. And different lenders use different methods.
Some use a Household Expenditure Measure (HEM) benchmark for living expenses — that’s the floor. Others use your declared expenses and apply their own multiplier. The gap between the most conservative lender and the most generous one can easily be $150,000 on the same income.
Then there’s rental income. When you’re buying an investment property, lenders count a portion of the expected rent as income — but not all of it. Most use 80%. Some use 75%. A few will go to 90% on strong rental markets. That alone shifts your borrowing power significantly.
A Real Scenario: Michael and Sandra, Inner West Sydney
Michael and Sandra own a home in Leichhardt, valued at $1.55 million. They owe $560,000 on it. Combined income: $210,000. They want to buy an investment property in Marrickville for $920,000.
They go to their bank. The bank stress-tests at 9.3%, uses 80% of $650 per week in estimated rent, and caps servicing. They’re approved for $730,000 — not enough.
We reviewed their situation and found three lenders with meaningfully different assessment methods. One accepted 90% of the rental income, used a lower HEM tier based on their actual expenses, and had a stress buffer at 3% above their product rate (not above the floor rate). Result: approval for $920,000 with interest-only for five years.
Same income. Same property. Different lender. $190,000 difference in what they could borrow.
Interest-Only: The Investor’s Tool That Banks Discourage
You’ll notice we structured the above deal with interest-only repayments for five years. This is a standard strategy for investors, and for good reason.
On a $920,000 loan at 6.3%, principal-and-interest repayments are around $5,690 per month. Interest-only? Around $4,830. That’s $860 per month in your pocket — money you can use to fund the holding costs, build a buffer, or accelerate repayments on your home loan (which isn’t tax-deductible).
Banks often push investors toward P&I because it reduces their risk. A broker looks at your whole financial picture and structures the loan around your actual goals.
Equity Access: Using What You Already Have
One thing that surprises a lot of Sydney homeowners: you don’t always need a 20% deposit sitting in cash.
If your home has gone up in value — and in Sydney, it probably has — you may have enough equity to fund the deposit without touching your savings. This is called a cash-out refinance, and it works like this:
Your home is worth $1.4 million. You owe $500,000. Usable equity (to 80% LVR): $620,000. You refinance and draw $200,000 to use as a deposit on the investment property. You then take out an $850,000 investment loan. Net result: two properties, mostly funded by your existing equity growth.
The bank won’t suggest this because it means refinancing away from them or taking on more debt than they’d like to write. A broker will map it out clearly, show you the repayment structure on both loans, and make sure you understand the full picture before you commit.
What About Low Doc Options?
If you’re self-employed, a freelancer, or running a business where your financials are complex, the standard process can be a nightmare. Two years of tax returns. BAS statements. Company financials. And then still being told no.
Low doc investment loans exist for exactly this situation. You verify income using alternative documentation — 12 months of BAS, an accountant’s declaration, or bank statements — and the lender assesses on that basis.
Rates are slightly higher (typically 0.5%–1.0% above standard), but they open the door for borrowers who can genuinely service the loan but don’t fit the standard PAYG mould. And in Sydney, where a significant chunk of investors are business owners or contractors, this matters.
The Numbers at Stake
Let’s be blunt about what going to a single lender costs you.
On a $900,000 investment loan over 30 years, the difference between 6.19% and 6.59% is around $2,100 per year in extra interest. Over five years, that’s $10,500 — before compounding. On a $1.2 million loan, you’re looking at closer to $14,000 over five years.
A broker compares rates across 40+ lenders. Finding even a 0.3% improvement pays for the entire process many times over — and the broker’s fee is typically covered by lender commissions, meaning it costs you nothing directly.
Why Loan Connect?
We work with buyers across Greater Sydney who are looking to buy their first investment property, build a portfolio, or pull equity from their existing home to make the next move.
We don’t work for any single bank. We compare lenders — major banks, non-banks, credit unions, specialist lenders — and find the structure that actually fits your situation. Not the product that’s easiest to sell.
