Investment Property Selection for Plumbers

You need to pick a rental property that will hold its value and generate rental income without forcing you to chase tenants or fork out for constant repairs.

Most plumbers looking at an investment property focus on upfront price and assume the numbers will sort themselves out. They won't. The property you choose determines whether you build wealth through passive income or spend years subsidising a loss-making asset. Your investment loan terms matter, but the property itself matters more. Buy the wrong place and no loan structure will save you.

Pick a Property Type That Rents Fast and Holds Value

Units and townhouses in established suburbs within 15 kilometres of the CBD rent faster and hold value better than outer-fringe houses in new estates. A two-bedroom unit near public transport and shops will typically stay tenanted with minimal vacancy, while a four-bedroom house 40 kilometres out might sit empty for weeks between tenants.

Consider a plumber who bought a two-bedroom unit in a Brisbane suburb like Coorparoo. The property cost $520,000 with a 15% deposit, requiring a $78,000 upfront payment plus stamp duty and costs. The unit rented for $500 per week within ten days of settlement. Body corporate fees ran $1,200 per quarter, but the vacancy rate stayed under 3% over three years because the suburb had strong transport links and consistent tenant demand. The property value grew modestly, and the rental income covered most of the interest only investment loan repayments. That outcome came from property selection, not luck.

Outlying estates might look cheaper upfront, but longer vacancy periods and slower capital growth usually offset the lower purchase price. You want tenants who stay and pay, not constant turnover.

Run the Numbers on Rental Yield Before You Commit

Rental yield tells you how much income the property generates relative to its purchase price. Calculate it by dividing annual rent by the property price and multiplying by 100. A property returning 4.5% or higher in gross yield will usually cover more of your holding costs than one returning 3%.

A $450,000 property renting for $420 per week generates $21,840 annually, giving a gross yield of 4.85%. A $600,000 property renting for $480 per week generates $24,960 annually, but the yield drops to 4.16%. The second property costs you more to hold even though the rent is higher. You want the property that returns the most relative to what you borrowed, not just the highest dollar rent.

Don't ignore claimable expenses like interest, property management fees, council rates, and maintenance when calculating your actual return. These reduce your taxable income and improve your cash position through maximise tax deductions. The property investor loan structure you choose, whether interest only or principal and interest, also affects your cash flow. Interest only loans reduce your monthly repayment but don't build equity. Principal and interest loans cost more per month but reduce your loan amount over time.

Check the Local Vacancy Rate and Tenant Demand

The vacancy rate in a suburb tells you how hard it will be to keep your property rented. Vacancy rates under 2% mean strong tenant demand and minimal downtime between leases. Rates above 4% mean your property could sit empty for weeks or months, costing you thousands in lost rent.

Look at suburbs with stable employment, transport access, and local amenities like schools and shops. Areas relying on a single employer or industry carry higher risk. If that employer shuts down or relocates, tenant demand drops and vacancy rates spike. Diversified suburbs with mixed employment and demographics hold up better during economic shifts.

You can check vacancy data through real estate websites or ask local property managers directly. They'll tell you how long properties in that area typically take to rent and what condition tenants expect. A suburb with 1.5% vacancy and consistent demand will keep you in positive cash flow. A suburb with 5% vacancy will bleed you dry while you wait for tenants.

Factor in Maintenance Costs and Building Age

Older properties cost more to maintain and carry higher risk of unexpected repairs. A 1970s unit might need rewiring, plumbing upgrades, or waterproofing work within a few years of purchase. A property built in the last 15 years will generally need less work and come with builder's warranty coverage on major structural elements.

You know what a full plumbing replacement costs. Apply that same scrutiny to the electrical, roofing, and structural condition before you buy. Get a building and pest inspection done by someone who won't gloss over problems. If the property needs $30,000 in repairs within two years, that wipes out any equity release or capital growth you were counting on.

Newer properties also qualify for higher depreciation deductions, which reduce your taxable income. An accountant can calculate the depreciation schedule, but newer buildings typically return better tax benefits in the first ten years. That improves your after-tax return without changing the rent.

Understand How Loan to Value Ratio Affects Your Borrowing

The loan to value ratio (LVR) is the percentage of the property price you borrow. An LVR above 80% usually triggers Lenders Mortgage Insurance (LMI), which can add thousands to your upfront costs. A $500,000 property with a 10% deposit means an LVR of 90% and LMI of around $15,000 to $20,000 depending on the lender.

You can avoid LMI by putting down 20% or more, or by accessing lender programs that waive LMI for certain occupations. Some lenders offer LMI waivers for tradies with strong income and employment history. That can save you a significant amount on the upfront cost and improve your return on investment.

If you already own property, you may be able to leverage equity from your existing home to fund the deposit on the investment property. Equity release lets you borrow against the value in your current property without selling it. That avoids the need to save a full deposit from cash, but it increases your overall debt and requires careful management of repayments across both loans.

Choose Between Variable Rate and Fixed Rate Loan Options

A variable interest rate moves with the market and gives you flexibility to make extra repayments or refinance without penalty. A fixed interest rate locks in your repayment for a set period, usually one to five years, but limits your ability to pay down the loan early or switch lenders without break costs.

Most plumbers prefer variable rates on investment property finance because they want the option to pay down debt or refinance when investor interest rates drop. Fixed rates suit you if you want certainty on repayments and plan to hold the property long-term without making changes to the loan structure.

You can also split the loan between variable and fixed, taking part of each. Some lenders offer investment loan features like offset accounts or redraw facilities on variable portions, which help manage cash flow and reduce interest costs over time. Access investment loan options from banks and lenders across Australia to compare which features suit your property investment strategy.

Avoid Properties That Look Like Bargains But Cost You Later

Properties priced well below suburb averages usually have a reason. It might be a busy road, no parking, poor layout, or a difficult body corporate. Those issues won't disappear after settlement. They'll reduce your rental appeal and make the property harder to sell when you want to exit.

Buying an investment property is not about finding the cheapest option. It's about finding the property that will rent consistently, require minimal maintenance, and hold value over time. A property that costs $50,000 less but sits vacant for three months every year will cost you more than a property priced at market value that rents immediately and stays tenanted.

Focus on properties that tenants actually want to live in. That means reasonable proximity to work, transport, and amenities, plus a layout and condition that doesn't scream deferred maintenance. You want a property that works for you, not one that gives you a second job.
