How Interest Rates Control Your Borrowing Capacity
Your borrowing capacity drops roughly $50,000 for every 1% rise in interest rates on a typical tradie income. Lenders assess every application at a rate 3% higher than the actual loan rate, which means when advertised rates climb, your maximum loan amount falls hard and fast.
Consider a landscaper earning $95,000 a year with $800 in monthly commitments. At a 6% variable rate, lenders test serviceability at 9%. That same income tested at a 7% variable rate gets assessed at 10%, cutting borrowing capacity by around $80,000. The assessment rate buffer sits at 3 percentage points above the product rate regardless of whether you choose variable or fixed, and APRA has held that buffer since late 2021.
When you apply for finance for tradies, the lender runs your income and expenses through a serviceability calculator that assumes rates will be higher than today. That assumption protects you from taking on a loan you cannot afford if rates rise further, but it also means your borrowing limit is lower than you might expect based on today's repayments alone.
Why Landscapers Face Tighter Lending in a High Rate Environment
Self-employed landscapers get hit twice when rates climb. First, your borrowing capacity drops like everyone else's. Second, lenders apply closer scrutiny to income that fluctuates seasonally or depends on contract work. If your last two tax returns show strong profit but your most recent BAS statements reflect a quieter winter, some lenders will average or discount your income further, shrinking your borrowing power even more.
Lenders treating trade income conservatively will apply a loading or reduction to declared earnings, particularly where work is project-based rather than recurring. A landscaper running $180,000 through the books might see that figure shaded to $140,000 or $150,000 for serviceability purposes, depending on the lender's policy and how your accountant has structured profit and drawings. At current rates, a $30,000 income reduction can cut your borrowing limit by $150,000 or more.

The Debt-to-Income Limit That Came Into Force in February
From 1 February this year, APRA restricted ADIs from lending more than 20% of new owner-occupier loans and 20% of new investor loans to borrowers with a debt-to-income ratio of six times or greater. If your total borrowing is six times your gross annual income or higher, you fall into that restricted pool, and not every lender will approve the loan even if it passes the serviceability test.
For a landscaper earning $95,000, the six-times threshold sits at $570,000. Borrow more than that and you are competing for a slot in the lender's restricted allocation. Some lenders have tightened policy further and will not lend above five or five and a half times income regardless of serviceability. Non-ADI lenders are not subject to the DTI cap, which gives you more options if your application sits above the threshold, but rates and fees can be higher.
How to Improve Your Borrowing Capacity Before You Apply
Pay down non-deductible debt first. Credit cards, car loans, and buy-now-pay-later accounts all count as ongoing commitments in the serviceability calculation. A $10,000 car loan with $400 monthly repayments can reduce your borrowing capacity by $60,000 to $80,000 depending on the lender. Clearing that debt or refinancing it into a longer term with lower repayments improves your serviceability immediately.
If you hold a credit card, lenders assess the liability at the full limit, not the outstanding balance. A $20,000 limit you rarely use still costs you around $100,000 in borrowing capacity. Cancel cards you do not need or reduce limits to the minimum you actually require. Some lenders will allow you to close accounts after the loan is approved, but most require evidence the account is closed before they will exclude it from the assessment.
For self-employed applicants, work with your accountant to structure the next tax return in a way that maximises your assessable income without creating an unnecessary tax burden. Lenders typically use the lower of the last two years' taxable income, so if one year is significantly weaker, you are locked into that figure until the next return is lodged. Timing your application to follow a strong financial year gives you the highest possible serviceability outcome.
What Happens When Rates Drop Again
Borrowing capacity moves in reverse when rates fall. A 1% drop in the variable rate increases your maximum loan amount by roughly $50,000 on the same income and commitments. The assessment rate buffer remains at 3 percentage points, so a fall in the product rate flows through to a lower test rate and improved serviceability.
If you are close to your target purchase price but cannot quite borrow enough at current rates, getting home loan pre-approval now locks in your position so you can move quickly when either rates drop or your income improves. Pre-approval typically lasts 90 days, and some lenders will extend it if your circumstances have not changed. You are not obliged to proceed with the loan, and there is no cost to obtain pre-approval through a broker.
Split Loans and Offset Accounts Do Not Change Your Borrowing Capacity
Your total borrowing limit is determined by your income, expenses, and the assessment rate. Choosing a split loan or adding an offset account does not increase the amount you can borrow. What these features do is give you more control over interest costs and repayment flexibility after settlement.
A split loan divides your borrowing between fixed and variable portions. You might fix 50% at a lower rate for certainty and keep 50% variable with an offset account for flexibility. The lender still assesses the full loan amount at the test rate, but the structure can reduce your actual repayments and let you park savings in the offset to cut interest. For home loans for landscapers, an offset account is particularly useful when you are holding funds for equipment purchases, tax, or SuperStream payments and want to keep those savings working against your mortgage.
Fixed Rates Look Lower But Do Not Improve Serviceability
Fixed rates are often lower than variable rates, but lenders still assess your serviceability at the higher of the fixed rate plus 3% or the variable rate plus 3%. If the fixed rate is 5.8% and the variable rate is 6.2%, your serviceability is tested at 9.2%, not 8.8%. The buffer applies to whichever rate is higher, so fixing at a lower rate does not unlock additional borrowing capacity.
Fixed rates do lock in your repayments for the fixed period, which can make budgeting easier if your income fluctuates or you want certainty over the next few years. Once the fixed term ends, the loan reverts to the lender's variable rate unless you refix or refinance. Most fixed loans allow limited extra repayments, typically up to $10,000 or $20,000 per year, and charge break costs if you exit the loan early. Read the terms carefully before you commit.
Use a Broker Who Understands Trade Income
Not all lenders assess self-employed income the same way. Some will accept one year of tax returns if your ABN is newer. Others will gross up your net profit to account for non-cash deductions like depreciation. A broker who works with tradies regularly knows which lenders to approach based on how your income is structured and where you sit relative to the DTI threshold.
When you apply for home loans for tradies, the broker submits your application to lenders most likely to approve it at the rate and loan amount you need. That saves time, avoids multiple credit enquiries, and gets you a confirmed borrowing capacity before you start looking at properties. Most brokers do not charge you a fee because they are paid by the lender once the loan settles.

Frequently Asked Questions
How much does a 1% interest rate rise reduce borrowing capacity?
A 1% rise in interest rates typically reduces borrowing capacity by around $50,000 on a standard tradie income. Lenders assess serviceability at 3% above the loan rate, so when rates climb, your maximum loan amount drops significantly.
Do fixed rates improve your borrowing capacity?
No. Lenders assess serviceability at the higher of the fixed rate plus 3% or the variable rate plus 3%. Even if you fix at a lower rate, the lender still tests your capacity at the higher assessment rate.
What is the debt-to-income limit that applies to home loans?
From February this year, APRA restricted ADIs from lending more than 20% of new loans to borrowers with debt six times their annual income or greater. If you exceed six times, you fall into a restricted pool and not all lenders will approve the loan.
How can self-employed landscapers improve borrowing capacity?
Pay down non-deductible debt like car loans and credit cards, reduce or cancel unused credit card limits, and work with your accountant to structure your tax return to maximise assessable income. Timing your application after a strong financial year also helps.
Does an offset account increase how much you can borrow?
No. Your borrowing capacity is set by income, expenses, and the lender's assessment rate. An offset account reduces the interest you pay after settlement but does not change the amount you can borrow upfront.
