You can purchase property with a 5% deposit.
The main difference between putting down 5% and the traditional 20% is you'll pay Lenders Mortgage Insurance. That cost gets added to your loan amount in most cases, so you're not paying it upfront. What matters more is whether you've got enough genuine savings, how stable your income looks to a lender, and whether the numbers stack up on servicing.
For plumbers, the serviceability calculation often works in your favour because consistent wage income or ABN turnover gives lenders confidence. The challenge is less about whether you can borrow at 5% and more about understanding what you're committing to when LMI gets factored in.
What Lenders Mortgage Insurance actually costs
LMI is a one-off premium charged when your deposit sits below 20%. The insurer protects the lender if you default, not you. The premium depends on your loan amount and how much you're borrowing as a percentage of the property value, which is your loan to value ratio.
Consider a plumber purchasing at a property value requiring a loan amount that puts the LVR at 95%. LMI on that scenario could add anywhere from a few thousand to over $10,000 to the total debt. That premium gets capitalised into the loan, so you're paying interest on it for the life of the loan unless you refinance or pay it down early.
Some lenders offer LMI waivers for tradies in specific circumstances, usually tied to your occupation and income level. If you're earning a wage and the lender has a professional package that includes plumbers, you might avoid the premium altogether. Not every lender extends that waiver to self-employed plumbers, so it pays to check.
Genuine savings versus gifted deposits
Lenders want to see genuine savings, which means money that's been in your account for at least three months. If your 5% deposit is made up of cash that appeared last week from a family member, most lenders won't accept it as genuine savings unless it's a formal gift with a signed declaration.
You need enough in savings to cover the deposit plus settlement costs. That includes conveyancing, building and pest inspections, and any lender or government fees. If your deposit is exactly 5% and you've got nothing left over, you'll struggle to get the application across the line.
In our experience, plumbers who've been putting aside a set amount each week from their wage or drawing a consistent salary from their business have the cleanest paper trail. Lump sums from tax returns, work bonuses, or the sale of a ute can all count, but they need to be declared and explained.

How income assessment works for employed versus self-employed plumbers
If you're on a wage, lenders assess your most recent payslips and your tax return. Overtime and allowances usually count if they've been consistent over the last 12 months. That means your tool allowance, travel pay, and any regular weekend or after-hours work can be included in your income calculation, which can lift your borrowing capacity.
Self-employed plumbers get assessed differently. Most lenders want two years of tax returns, and they'll use your taxable income or the net profit from your business. If you've been claiming every deduction possible to reduce your tax bill, that same approach cuts into what the lender thinks you can afford to repay.
Some lenders offer low doc options where you can declare your income without full financials, but those products usually come with higher interest rates and won't suit a 5% deposit scenario because the lender is already taking on more risk with a high LVR.
Variable rate, fixed rate, or splitting the loan
You'll need to choose between a variable rate and a fixed interest rate when you apply. A variable rate moves with the market, which means your repayment amount can change. A fixed rate locks in your interest rate for a set period, usually between one and five years.
Some plumbers split the loan, fixing part of it for rate certainty and leaving the rest on a variable rate for flexibility. That approach works if you want the option to make extra repayments without hitting a fixed rate limit, but still want some protection against rate rises.
At current variable rates, an offset account linked to your home loan can reduce the interest you pay without locking you into a fixed term. If you're keeping a decent buffer in your account for materials, upcoming jobs, or tax, that linked offset can shave real dollars off your interest each month.
Applying for pre-approval before you start looking
Getting loan pre-approval gives you a clear budget and shows sellers you're a serious buyer. Pre-approval isn't a guarantee, but it means a lender has assessed your income, debts, and deposit and confirmed what they're willing to lend.
For plumbers working on a 5% deposit, pre-approval also flushes out any issues with your application early. If your savings aren't quite there yet, or your income documentation needs cleaning up, you'll know before you waste time looking at properties you can't finance.
Pre-approval typically lasts 90 days, which gives you three months to find a property and make an offer. If rates or your circumstances change during that period, the lender can reassess, but the bulk of the work is already done.
What happens after you make an offer
Once your offer is accepted, the lender orders a valuation to confirm the property is worth what you're paying. If the valuation comes in under the purchase price, the lender will only lend based on the lower figure, which means your deposit percentage just went up or you need to renegotiate.
Settlement usually takes 30 to 60 days depending on what's in the contract. During that time, the lender finalises your loan documents, you organise insurance, and your conveyancer handles the legal side. If you're purchasing an owner occupied home loan, you'll need to move in or intend to live there within a set timeframe, usually six months.
The loan amount gets released to your conveyancer on settlement day, and ownership transfers to you. That's when the LMI premium gets added to your loan balance if it applies, and your regular repayments start.

Frequently Asked Questions
Can I buy a property with only a 5% deposit?
Yes, you can purchase property with a 5% deposit. The main requirement is that you'll pay Lenders Mortgage Insurance, which protects the lender when your deposit is below 20%. You'll also need enough genuine savings to cover both the deposit and settlement costs.
What is Lenders Mortgage Insurance and how much does it cost?
LMI is a one-off premium charged when your deposit is less than 20% of the property value. The cost depends on your loan amount and loan to value ratio, and can range from a few thousand to over $10,000. This premium is usually added to your loan amount rather than paid upfront.
Do self-employed plumbers get assessed differently for a home loan?
Yes, self-employed plumbers typically need to provide two years of tax returns, and lenders assess your taxable income or net business profit. If you're on a wage, lenders use recent payslips and can include consistent overtime and allowances in your income calculation.
What are genuine savings and why do lenders require them?
Genuine savings are funds that have been in your account for at least three months. Lenders require them to demonstrate you can save consistently and manage money responsibly. Gifted deposits usually don't count as genuine savings unless properly documented with a signed declaration.
Should I choose a variable or fixed interest rate with a 5% deposit loan?
Both options work with a 5% deposit. A variable rate offers flexibility for extra repayments and moves with the market, while a fixed rate provides payment certainty for a set period. Many plumbers split their loan to get both flexibility and some protection against rate rises.
