Using Equity to Buy Investment Property: What to Know

Your home equity can fund the deposit for an investment property without touching your savings.

Many officers in Western Australia already own their home and have built up usable equity through repayments and property value growth. That equity can be released and used as security or deposit funds for a second property, which means you can invest without waiting years to save another 20 per cent deposit. The calculation involves your current property's value, what you owe, and what the lender will allow you to borrow against it. Most lenders will let you access equity up to 80 per cent of your home's current value, though some products for police officers allow higher loan to value ratios with reduced or waived Lenders Mortgage Insurance.

How Equity Release Works for a Second Property

You borrow against the increased value of your current home to fund the deposit and costs on the investment property. Say your home is now worth $650,000 and you owe $380,000. At 80 per cent LVR, the lender would allow total borrowing of $520,000 against that property, which leaves $140,000 in usable equity. That $140,000 can cover a deposit, stamp duty, and settlement costs on the investment property while the new loan for the purchase sits separately. Both loans are secured, one against your home and one against the investment property, but the equity acts as the bridge between them.

Some lenders structure this as a single loan split across two securities. Others keep the loans separate but cross-collateralise them, meaning both properties secure both loans. The structure affects how much flexibility you have later if you want to sell one property or refinance. In our experience, keeping loans separate where possible gives you more options down the line, particularly if you're planning to build a portfolio beyond two properties.

What Lenders Look at When You Apply

Lenders assess your borrowing capacity based on your income, existing debts, and the rental income the new property is expected to generate. They apply a serviceability buffer, usually 3 percentage points above the current interest rate, and they discount the expected rental income by around 20 per cent to account for vacancy and maintenance. For shift workers, some lenders will include allowances and penalty rates in the income calculation, but others cap overtime or exclude it entirely. That variance makes lender selection crucial for police officers.

Debt-to-income caps introduced in February apply separately to investor and owner-occupier lending, so lenders can still approve up to 20 per cent of their investor loan book at DTI ratios of six times or higher. If your total debt would sit above six times your gross income, the loan is still possible but fewer lenders will write it. That means your application may take longer and your rate may be less competitive. Preparing a clear picture of your income, including any regular allowances, helps the broker present your application in the format each lender prefers.

Interest Only Repayments and Cash Flow

Most investors choose interest only repayments for the first five years to keep cash flow manageable. You're only paying interest, not reducing the loan balance, which lowers the monthly commitment and can make the property cash flow neutral or close to it once rental income is included. At the end of the interest only period, the loan converts to principal and interest unless you apply to extend it. Lenders typically allow one extension, giving you up to ten years interest only in total.

The appeal for officers working rosters is predictable repayments that don't stretch your budget during quieter income periods. Consider a constable earning $95,000 base plus allowances who borrows $450,000 for an investment property at an interest rate of around 6.3 per cent. Interest only repayments would sit near $2,360 per month. If the property rents for $550 per week, that's $2,383 per month in gross rental income. After the lender applies their 20 per cent discount, serviceability is calculated on $1,906, but the actual rent received covers the repayment before expenses. Once you account for body corporate, rates, insurance, and periodic maintenance, the property may be slightly negatively geared, but the shortfall is small and the interest is tax deductible.

Tax Treatment Changes from July 2027

Negative gearing rules change from 1 July 2027 for properties purchased after 7:30pm on 12 May 2026. If you buy an established dwelling after that date, any net rental loss can only be offset against other residential rental income or carried forward. You can't offset the loss against your salary. Properties held before that date, or purchased under contract before that date, continue under the old rules where losses can reduce your taxable income from any source. Eligible new builds purchased after the cut-off retain full negative gearing, meaning losses can still offset wage income.

If you're planning to use equity to buy an investment property this year or next, timing matters. Buying before mid-2026 locks in the current tax treatment. Buying after that date into an established property means rental losses are quarantined, though you can still carry them forward and use them against future rental income or capital gains when you eventually sell. The change doesn't stop you claiming interest, but it does change when and how you can use the deduction. For officers in higher tax brackets, that shifts the cash flow equation. It doesn't eliminate the case for investing, but it does mean your after-tax position will differ depending on when you buy and what you buy.

Loan Structure and Future Flexibility

How your loans are structured affects what you can do later. Cross-collateralisation means both properties secure both loans, so if you want to sell the investment property or refinance it separately, you need the lender's consent to remove it from the security pool. That can delay a sale or limit your refinancing options. Keeping the loans separate, each secured only by its own property, gives you more control. You can sell, refinance, or leverage one property without affecting the other.

Some lenders insist on cross-collateralisation when you're using equity from one property to fund another, particularly if the combined LVR is above 80 per cent. Others will structure it as two standalone loans if your borrowing capacity and equity position allow it. The difference isn't always obvious in the loan documents, so it's worth clarifying during the application. If you're planning to grow a portfolio beyond two properties, clean loan structures from the start make the third and fourth acquisitions much simpler. We regularly see officers who want to expand their property portfolio but find themselves stuck because their existing loans are tangled.

LMI Waivers and How They Apply to Investment Lending

Several lenders offer reduced or waived Lenders Mortgage Insurance for police officers on owner-occupied lending, and a smaller number extend that benefit to investment loans. LMI is usually charged when your LVR exceeds 80 per cent, and it protects the lender if you default. The premium can add tens of thousands to your loan amount, so a waiver or discount makes a material difference. Not all lenders publicise which occupations qualify, and the criteria vary. Some cap the waiver at 90 per cent LVR, others at 85 per cent, and some apply it only to refinances or only to purchases.

For an officer using equity to invest, an LMI waiver can mean accessing more equity from your home without paying the insurance clip, or it can mean buying the investment property with a smaller deposit and keeping more cash in reserve. The waiver applies to the loan, not the borrower, so if you're taking out a new loan secured by the investment property, the lender assesses that loan separately. If your combined borrowing across both properties pushes the investment property LVR above 80 per cent, the waiver on your occupation may still apply. Eligibility for LMI waivers depends on your employer, your role, and the lender's current policy, which is why working with a broker who knows which lenders offer what can save you real money.

Calculating What You Can Borrow

Your total borrowing capacity depends on your income, existing debts, living expenses, and the rental income from the new property. Lenders use a household expenditure measure, which is either your declared expenses or a benchmark figure, whichever is higher. For a single officer with no dependents, that benchmark might be $2,200 per month. For a family, it scales up. Your current home loan repayments, car loan, credit card limits, and any other debts are added to that, then subtracted from your net income. What's left is your surplus, and that surplus has to cover the new loan repayments at the serviceability rate.

Rental income is included but discounted. If the property is expected to rent for $500 per week, the lender uses $400 per week in their calculations. The difference between the actual rent and the discounted figure affects cash flow but not serviceability. Some lenders are more conservative and apply a 25 per cent discount, others sit at 20 per cent. If you're borrowing close to your maximum capacity, that 5 per cent difference can determine whether the loan is approved. Running the numbers before you start looking at properties tells you what price range is realistic and whether you need to pay down other debts first.

Investment Property Strategy and Location

The property you choose affects both your borrowing capacity and your long-term return. Lenders assess different property types and locations differently. A unit in a regional town with limited rental demand will be discounted more heavily than a house in an established suburb with low vacancy rates. Some lenders won't lend at all in certain postcodes or on properties in specific developments. Strata properties with short remaining lease terms, properties in buildings with known defects, and units in high-rise blocks above a certain floor count can all be declined or require larger deposits.

For officers looking to build wealth through property, the investment property strategy matters as much as the loan structure. Buying close to where you live can make management simpler, but buying in a higher-growth area, even interstate, can deliver better long-term returns. The rental yield, the vacancy rate, and the area's demographics all feed into whether the property will hold value and generate reliable income. Strata costs on units can be high, particularly in newer complexes with lifts, pools, and gyms. A $5,000 annual body corporate fee reduces your net rental income by nearly $100 per week, which changes the cash flow equation. Weighing up those factors before you commit helps you avoid buying something that looks affordable on paper but becomes a cash drain.
