Do you feel like your dream of owning a home in Sydney is a bit like chasing a runaway train? You’re running as fast as you can, but the goalpost, and the interest rates, just keep rocketing further ahead.
It’s a common feeling right now. With interest rates having climbed and the cost of living putting a squeeze on everyone’s back pocket, the amount banks are willing to lend has definitely "come off the boil." You might have even done a quick online calculator check and felt a total meltdown coming on when you saw the result.
But here’s the thing: it’s not impossible.
At Blueprint Financial Services, we see people every day who think they’re stuck, only to find out there are several levers we can pull to get that borrowing power back on track. There is one "simple trick" in particular that catches almost everyone out, and fixing it can catapult your borrowing capacity by tens of thousands of dollars almost overnight.
If you want to boost your borrowing power right now, the single most effective thing you can do has nothing to do with your salary.
It’s your credit card limit.
Annoying, right? You might have a $10,000 credit card limit "just in case" of emergencies, but you only ever spend a few hundred dollars on it and pay it off every month. You think you’re being responsible. But in the eyes of a bank lender, that $10,000 limit is a $10,000 debt you could choose to run up tomorrow.
Most lenders "stress test" your credit card at around 3% of the limit per month. So, that $10,000 card "costs" you $300 in monthly repayments in the bank’s calculator, even if the balance is zero. In today’s high-rate environment, that $300 "repayment" could slash your borrowing power by $40,000 or more.
The Fix: Lower your limits to the absolute minimum you need, or close the accounts entirely before you apply. It’s one of the fastest ways to see your borrowing capacity jump without needing a pay rise.
It’s worth noting that since early 2026, APRA has been keeping a very close eye on "high-debt" loans. Banks are now limited in how many loans they can give to people with high debt-to-income (DTI) ratios. This means they are crunching the numbers harder than ever.
When rates are high, the "buffer" the banks add (usually 3% on top of the actual rate) means they are testing if you can afford a mortgage at 9% or 10%. That’s a tall order! But don't be discouraged; this is where strategy comes into play.
While the credit card trick is the fastest, it’s not the only way to get ahead. If you’re a first-home buyer or an upgrader feeling the pinch, here are the nitty-gritty steps that actually move the needle:
If you have a car loan, a personal loan, or those "Buy Now, Pay Later" accounts (looking at you, Afterpay), they are eating your borrowing power for breakfast. Lenders look at the monthly repayment amount. If you’re paying $500 a month on a car loan, that’s $500 less "surplus" income the bank sees for a mortgage.
Closing these accounts or consolidating them can drastically change the landscape. If you can't close them, even extending the term of a car loan to lower the monthly repayment (check with your advisor first!) can sometimes help your serviceability.
Banks aren't just looking at what you earn; they’re looking at where it goes. Most lenders will want to see three to six months of bank statements. If they see "UberEats" and "Luxury Escapes" every second day, they'll use those figures instead of the standard Household Expenditure Measure (HEM).
By tightening the belt for just 90 days before you apply, you can show a "responsible" spending profile that gives the lender confidence you can handle a mortgage.
While the standard is 30 years, some lenders are now offering 40-year terms for certain borrowers. While you'll pay more interest over the life of the loan, it lowers the required monthly repayment, which can be a line-ball decision that gets you over the line for the property you actually want.
Are you getting bonuses? Overtime? Commissions? Not all banks treat this income the same. Some will only take 80% of it; others might take 100% if you’ve been receiving it for over a year. Knowing which lender loves your specific income structure is half the battle.
At Blueprint Financial Services, we don't just run your numbers through a basic online calculator. Those are great for a rough idea, but they don't tell the whole story.
Our secret sauce is our Deep Dive process. We’ve seen cases where a client went from a "No" at their local branch to a "Yes" with us, simply because we looked at their situation through a different lens.
Here is our 4-step process to getting you home:
The Sydney market waits for no one. Even with rates where they are, there are opportunities for those who are prepared. Whether you are looking into the First Home Guarantee or you're an experienced owner looking to refinance and optimize, the best time to start planning is today.
Don't let a generic bank calculator dictate your future. Your situation is unique, and there’s often a way forward that you haven't considered yet.
