Why Lenders Give Different Borrowing Limits in Wollongong, NSW, What Lenders Check
You sit down with two lenders, hand over the same payslips and bank statements, and walk away with two completely different borrowing limits. It happens constantly, and it's not a mistake. Lenders assess the same application through different filters, and the gap between the best and worst answer is often six figures.
If you're buying in Wollongong, NSW, where house medians run from around $670,000 in Cringila to well over $1.3 million in the northern coastal suburbs, that gap determines which suburb you can actually afford. Understanding what drives it is the difference between ruling yourself out early and finding the lender whose policy genuinely fits your situation.
The home loan structure and which lender you approach matters at least as much as the rate they offer. Our team compares across 60+ lenders and knows where the policy gaps sit.
Key takeaways
- Lenders use different expense benchmarks and income-shading rules.
- APRA's 3.0% buffer is applied on top of the actual rate by every lender.
- Credit card limits reduce borrowing capacity even at a zero balance.
Why do lenders come up with completely different borrowing numbers?
Every lender uses the same starting point: your gross income minus your committed expenses and existing debts. What differs is how each one defines and measures those inputs. One lender shades overtime income to 80% of the average; another counts it in full once you've held the role for twelve months. One lender applies the Household Expenditure Measure as the floor for your living costs; another accepts a lower declared figure if you can document it. The same application, filtered through two different credit policies, produces two different numbers.
We see it every week: a buyer gets one number from their bank, calls us, and after we run the same information through three other lenders they're looking at a figure that's often $80,000 to $120,000 higher. The policy gap is real, and it's widest on income types that aren't a clean base salary.

How does the APRA serviceability buffer actually work?
Every lender in Australia that holds an Australian banking licence must add a 3.0% buffer on top of the loan's actual interest rate when assessing whether you can afford the repayments. If the loan rate is 6.0%, you're assessed at 9.0%. This is the APRA serviceability buffer and it's not negotiable - no lender can waive it for a bank-licensed product.
What it means in practice is that your borrowing limit is set against repayments you won't actually be making. On a $900,000 loan over 30 years, the assessment rate adds a meaningful monthly buffer to what the lender counts as your required repayment. The buffer is designed to protect you if rates rise, but it also means most borrowers can borrow less than a simple income-times-six estimate would suggest.
Non-bank lenders are not authorised deposit-taking institutions and are not subject to APRA's lending rules, which is why some of them can offer a slightly more flexible assessment. They're still regulated by ASIC and still assess serviceability, but the specific 3.0% floor is an APRA requirement for ADIs only.

What income types do lenders assess differently in Wollongong?
A clean base salary paid by a single employer is the simplest income type to assess, and even there lenders differ on whether probation counts. Everything else introduces more variation. The income types that produce the widest lender spread are the ones most common across Wollongong's workforce - shift workers at Wollongong Hospital, university staff on fixed-term contracts at UOW, tradies on ABN income, and casual workers in the retail and hospitality sectors along Crown Street and through the Dapto corridor.
Where lender policy creates the biggest gaps:
- › Overtime and shift penalties: some lenders count these in full once you have a consistent history; others shade to 80% regardless of how long you've been earning it.
- › Casual and part-time income: most lenders want around twelve months in the same field before counting it at all; some accept less where the employment letter confirms ongoing availability.
- › Self-employed and ABN income: the standard is two years of tax returns, with add-backs for depreciation and one-off expenses accepted differently across lenders. Some accept an accountant's letter in place of a second return where the first year is strong.
- › Commission and bonuses: typically averaged over one to two years, but the minimum history required and the shading percentage differ between lenders - a one-year average at 100% versus a two-year average at 80% produces a meaningfully different assessed income.
- › Rental income: most lenders count around 80% of gross rent from an investment property; the holding costs are then added as commitments on top, so the net effect on borrowing capacity is smaller than most investors expect.
What expenses and debts reduce how much you can borrow in Wollongong?
Lenders assess your living expenses against the Household Expenditure Measure - a benchmark built from ABS survey data and updated quarterly. If your declared expenses are lower than the HEM floor for your household size and location, the lender substitutes HEM. Declaring less than you actually spend doesn't help, because the benchmark does the work below a certain point. HEM figures are licensed to lenders and not published publicly, so the number varies between lenders and is never available to borrowers directly.
On top of expenses, three commitment types cut capacity most sharply:
Credit cards: lenders assess your cards as though the limit is fully drawn, typically at around 3% to 3.8% of the limit per month. A $20,000 card limit adds roughly $600 to $760 in monthly commitments on a lender's model, whether your balance is zero or not. Closing cards before you apply - or before you apply to specific lenders - can shift the number meaningfully.
HECS/HELP debt: the repayment is assessed as an ongoing commitment, not the balance. Repayments are income-tested and rise as income rises, so a higher earner with a large HECS balance loses more capacity than a lower earner with the same balance. Paying out a small remaining HECS balance before applying is worth modelling; for a large balance the cash is usually better kept for the deposit.
Buy now pay later and ATO payment plans: both appear on bank statements and are treated as commitments by most lenders. No single published policy covers this - it's assessed individually - but both are safer closed before a formal application than left open.

What is the APRA debt-to-income cap and how does it affect your limit?
Since February 2026, APRA limits how much high debt-to-income lending any authorised bank can write. No more than 20% of new lending can carry a debt-to-income ratio of 6x gross income or higher. This cap tracks owner-occupier and investor lending in separate pools, so a lender that has written a lot of investment loans at high DTI ratios can still write owner-occupier loans - and vice versa.
In practice it means two things. First, a lender that is close to its cap for a particular pool may decline a file it would have written a month earlier. Second, investors and high-income earners with large existing debts are where the cap bites hardest. Construction loans and owner-occupier bridging loans are exempt from the cap.
Non-bank lenders are not ADIs and are not subject to this cap, which is a genuine reason to consider them - particularly for investors and for borrowers at higher income levels where total debt is the constraint.
If you're earning well but carry a large mortgage, HECS debt and a car loan, your DTI ratio is the number that may be limiting you across several lenders at once. The solution is often a non-bank lender, a different loan structure, or reducing one of the debts before applying - not simply finding a lender who will "work around it".

When does getting a higher borrowing limit not make sense?
Borrowing as much as a lender will give you and borrowing the right amount for your circumstances are not always the same thing. A lender's maximum is a credit risk assessment, not a recommendation for your household budget. If the repayments at the top of your limit leave less than a comfortable monthly buffer after living expenses, you're exposed the moment a rate moves or an income period changes.
There are also structural reasons to stay below the maximum. Cross-collateralising properties to extract more borrowing across a portfolio ties your assets together in a way that makes selling one property considerably more complicated - it requires the lender's consent and a revaluation across the whole position. Borrowing more to buy an investment property that produces negative cashflow before the 1 July 2027 negative gearing changes take effect is worth revisiting with your accountant before committing.
The right number is the one that lets you buy the property you want without financial stress, keeps a buffer for rate movements, and leaves room for the next decision - whether that's a renovation, a second property, or a change in income.
Where I'd push back is when a buyer wants to borrow to the maximum because the number is available. We'd usually model what a 0.5% rate rise does to those repayments first. If it looks uncomfortable on paper, it'll feel worse in practice, and finding a slightly cheaper suburb is a far better outcome than financial stress twelve months in.

How do you find out what you can actually borrow across different lenders?
The options worth comparing aren't just rates - they're the assessment policies that determine how much you can borrow in the first place.
The main pathways:
- › Your own bank: fastest to start · knows your transaction history · one set of policies, no comparison · often not the highest number
- › Applying to multiple lenders directly: each application generates a credit enquiry · multiple enquiries in a short window reduce your credit score · no visibility of policy differences before you apply
- › Comparing through a broker: one application assessed across 60+ lenders · policy differences surfaced before any credit enquiry is lodged · income-shading and DTI-cap positions identified per lender
A broker comparing across a broad panel is worth the most where your income is anything other than a clean base salary - that's where the policy differences are widest and where the right lender choice changes the outcome most.
How to compare your borrowing limit across lenders in Wollongong, NSW, step by step
Step 1: Talk to us
We start by understanding your income shape, existing commitments and target price range - not to pre-screen you, but to know which lender policies are worth running before anything is formally submitted.
Step 2: Map your position against lender policies
We run your figures through the lenders on our panel whose credit policies suit your income type, commitment profile and DTI ratio, identifying the realistic ceiling before any enquiry is lodged.
Step 3: Select the right lender and apply formally
Once we've identified the strongest fit, we prepare a complete application - income evidence, expense documentation, liability schedule - and submit it to a single lender with the highest probability of approval at the borrowing level you need.
Step 4: From approval to settlement
We manage the lender through conditional approval, valuation and formal approval, and stay in contact with your conveyancer and agent through to settlement so nothing stalls.
What mistakes do borrowers make when comparing borrowing limits?
Where buyers lose ground:
- › Applying to multiple lenders at once: each application leaves a hard enquiry on your credit file and stays there for five years. Three declined applications before finding the right lender costs you credit score points and can trigger further declines.
- › Leaving credit card limits open: a $15,000 card assessed at 3.8% of the limit adds around $570 per month in committed expenses on a lender's model. Closing unused cards before applying removes that commitment entirely.
- › Treating the bank's estimate as the market: a bank's online calculator uses that bank's policies. Two other lenders on a different shading model can produce a figure $80,000 to $100,000 higher on the same income. The first number you get is a starting point, not a ceiling.
- › Applying at the wrong time in the income cycle: self-employed borrowers whose most recent tax return is a low-income year can often wait one reporting period and apply on a much stronger income position. Pushing an application through early at a lower assessed income locks in a lower limit.
Frequently Asked Questions
Why did my bank give me a lower borrowing limit than a broker showed?
Your bank uses its own income-shading rules and expense benchmarks, and only compares within its own product range. A broker running the same figures through multiple lenders with different policies will often find one that assesses your income more favourably.
Does the APRA serviceability buffer apply to every lender?
The 3.0% APRA buffer applies to authorised deposit-taking institutions - banks and credit unions. Non-bank lenders are regulated by ASIC and still assess serviceability, but the specific APRA floor doesn't apply to them.
How much does a $20,000 credit card limit reduce my borrowing capacity?
Most lenders assess credit card limits at around 3% to 3.8% of the limit per month, regardless of the actual balance. A $20,000 limit adds roughly $600 to $760 in monthly commitments on a lender's model.
Can I borrow more by switching to a non-bank lender?
Sometimes, particularly if your DTI ratio is the constraint, since the APRA DTI cap applies to banks but not non-bank lenders. Non-bank products are still assessed on serviceability, so the lender still needs to be confident you can meet repayments - but the ceiling can be higher in the right circumstances.
Is a broker better than going direct to a lender for borrowing capacity?
A mortgage broker, every time, where your income is anything other than a simple base salary. The policy differences between lenders are widest on variable, casual, shift-based or self-employed income, and those differences are not visible until you compare across several lenders simultaneously.
Does HECS debt affect my borrowing limit even if I'm nearly finished paying it?
Yes - lenders assess the compulsory repayment as an ongoing commitment, not the remaining balance. Paying out a small remaining HECS balance before applying can lift your assessed borrowing capacity, though the cash trade-off is worth calculating first.
Your Next Steps
The borrowing limit you're working with might not be the market's answer for your situation. Two lenders assessing the same income through different policies is a feature of Australian mortgage lending, not an anomaly, and knowing where the differences sit is what lets you find the right one without damaging your credit file along the way.
The right lender for your borrowing limit depends on your income shape, commitments and the property you're buying - and that's a conversation worth having. Talk to the SimpleFin team or call 0457 531 124, and we'll compare your options across 60+ lenders.
