If you’ve been asking yourself how much can I borrow for a home loan in Sydney, you’re not alone. It’s the question on every buyer’s lips right now — and with good reason. Interest rates have moved, lender appetite has shifted, and what the banks are willing to offer in mid-2026 looks different from even six months ago.
Here’s a straight-talking breakdown of what actually determines your borrowing capacity, how the current rate environment is affecting Sydney buyers, and what you can do to put yourself in the strongest possible position before you walk into a lender.
The Short Answer: It Depends on More Than Your Salary
Most people assume their income is the number that matters most. And yes, income is a big piece — but it’s not the whole picture. Lenders assess your borrowing capacity using what’s called a serviceability assessment. They take your income, subtract your living expenses and existing debts, and then stress-test what’s left at a rate typically 3% above the loan’s actual rate.
That serviceability buffer is set by APRA and it exists to make sure you can still meet repayments if rates rise again. It’s been the quiet killer of borrowing power for a lot of Sydney buyers over the past two years.
So if you’re looking at a loan rate of 6.5%, the bank is testing your ability to repay at 9.5%. That’s a significant difference — and it directly limits the amount they’ll approve.
What’s Changed in 2026
The RBA hiked rates earlier this year — the first increase in over two years — and several major banks are now pricing in at least one more move. That’s squeezing borrowing capacity across the board. According to Canstar, each 0.25% rate rise knocks around $12,000 off the average income earner’s maximum loan amount. Two hikes, and you’re looking at roughly $24,000 less in buying power.
For Sydney, where median house prices are sitting north of $1.5 million in most suburban rings, that’s meaningful. It won’t push most buyers out of the market entirely, but it does change the conversation — especially for those buying near their limit.
The good news? Lender competition hasn’t disappeared. The non-major banks and specialist lenders are still hungry for business, and there’s real variation in how different lenders assess income types, expenses, and existing debts. This is where working with a mortgage broker pays off in a real, dollar-figure kind of way.
The Key Factors That Determine How Much You Can Borrow
Here are the levers that matter most:
1. Gross Income — All Sources Count
Salary is the baseline, but rental income, freelance work, dividends, and even overtime can all count — depending on the lender and how that income is documented. PAYG borrowers are usually straightforward. Self-employed borrowers need two years of tax returns showing consistent income. Some lenders will use your most recent year if it’s higher; others average the two. Knowing which lender suits your income profile is half the battle.
2. Existing Debts and Credit Limits
This one catches a lot of people off guard. Lenders don’t just look at what you owe — they look at what you could owe. That $20,000 credit card limit? Even if the balance is zero, it’s assessed as a potential liability. A car loan with three years remaining is factored in too. If you’re serious about maximising your borrowing power, review your credit profile before you apply. Closing unused cards and paying down revolving debt can meaningfully improve your numbers.
3. Living Expenses — The Household Expenditure Measure
Lenders use a benchmark called the Household Expenditure Measure (HEM) as a floor for living expenses. If your declared expenses are lower than the HEM for your household size, the bank uses the HEM anyway. Sydney households typically have higher assessed living costs than the national average — that’s just the reality of living in one of the world’s most expensive cities. Being prepared with accurate expense records helps, but don’t expect lenders to take a haircut on Sydney living costs.
4. Deposit Size and LVR
Your loan-to-value ratio (LVR) affects both your borrowing limit and your interest rate. Borrowing above 80% LVR usually means paying Lenders Mortgage Insurance (LMI), which gets rolled into the loan and adds to your overall debt. Some lenders offer waived LMI for specific professions — medical, legal, accounting — which can save tens of thousands. For most buyers, aiming for a 20% deposit gives you the cleanest approval pathway and the best rates.
A Real-World Sydney Example
A couple in their early 30s, living in Parramatta, both working full-time with a combined income of $180,000. No kids, one car loan of $15,000 outstanding, and a credit card with a $10,000 limit. At current rates, they might qualify for somewhere in the range of $800,000 to $900,000 — depending on the lender and how their expenses are assessed. That positions them for a solid apartment in the inner west, or a house in some of the outer western suburbs like Penrith or Campbelltown.
If they cleared the credit card limit before applying? That number could shift by $30,000 to $50,000 in their favour. Small moves, real impact.
How to Improve Your Borrowing Capacity Before You Apply
- Cancel unused credit cards — limits count against you even if you never use them
- Pay down HECS/HELP debt if it’s significant — it reduces your net income in the lender’s eyes
- Avoid new debt or major purchases in the three to six months before applying
- Stabilise your income — job changes near application time can complicate approvals
- Document every income source — bonuses, allowances, investment income, all of it
- Get your tax returns up to date — particularly critical for self-employed borrowers
The Broker Advantage in a Tighter Market
When rates were low and lenders were competing hard for volume, most people could walk into a bank and get a reasonable deal. That’s still possible — but the variation between lenders has widened, and the margin for error on your application has narrowed.
A broker’s job is to know which lender will look favourably at your specific situation. Someone who earns mostly commission income needs a different lender than someone on a fixed salary. A business owner with two strong years and one off year is assessed completely differently depending on where they apply. Getting this right the first time matters — multiple credit enquiries from declined applications can actually damage your credit score and make the next application harder.
If you’re trying to figure out your borrowing capacity before you start making offers, talking to a broker first is the move. It costs you nothing, takes less than an hour, and gives you a realistic, lender-backed number to work with — not a calculator estimate that may or may not reflect how a bank actually sees you.
What’s Next for Sydney Buyers
The market is in a holding pattern right now. Prices in Sydney have softened slightly, clearance rates have eased, and buyers have a little more time to make decisions than they did in the frenzy of 2024. That’s not a bad thing. A slower market rewards preparation. Buyers who know their numbers, have their documentation ready, and have a pre-approval in hand are still closing deals — often at better prices than a year ago.
The buyers sitting on the sidelines waiting for rates to drop may find themselves competing in a very different market by early 2027 when economists expect conditions to tighten again. The window right now is real — but only for those who are ready.
