When to Use an Investment Loan for a New Property

A practical look at how WA Police officers can fund an investment purchase with the right loan structure and timing.

An investment loan lets you borrow to purchase a rental property while keeping that debt separate from your home loan.

For officers working shift rosters, building something outside your primary income makes sense when you're not always in a position to pick up overtime or side work. A rental property creates another income stream without needing you to clock on. The structure you choose for that loan affects your cash flow, your tax position, and how much flexibility you have when rates move or your circumstances change.

How Investment Loans Differ from Owner-Occupier Loans

Investment loans attract a slightly higher rate than owner-occupier products because the lender treats them as higher risk. You'll also need a larger deposit, typically at least 10 per cent plus costs to avoid Lenders Mortgage Insurance, though some lenders may accept less if you meet their criteria. The repayments aren't tax deductible on a home loan, but on an investment loan the interest component is claimable against your rental income.

Consider an officer purchasing a unit in Baldivis. With a 15 per cent deposit, they borrow at a variable rate around 0.4 to 0.5 percentage points above what they'd pay on their own home. That difference costs roughly $40 per week on a $400,000 loan, but the entire interest expense is deductible. Over the year that deduction reduces taxable income by around $20,000, which at the marginal rate delivers a refund that more than covers the rate difference.

Interest Only or Principal and Interest

An interest only loan keeps your repayments lower during the initial period, usually up to five years, which can help with cash flow if the property is negatively geared. Once the interest only term ends, repayments increase because you then start paying down the principal over the remaining loan term. Principal and interest repayments build equity from day one but cost more each month.

For officers whose income includes allowances or penalty rates that vary depending on roster, the lower repayment on interest only can provide breathing room during quieter months. You're still free to make extra repayments when you want to reduce the balance, and many lenders allow this without penalty on variable products. If you're planning to sell within a few years or reinvest that cash flow into another property, interest only makes sense. If you're holding long term and want the loan paid down before retirement, principal and interest is the safer path.

Borrowing Capacity When You Already Have a Home Loan

Lenders assess your ability to service both loans at the same time. They'll add a buffer of at least 3.0 percentage points to the actual rate and include your existing home loan repayments, credit card limits, and living expenses in the calculation. Rental income is included, but most lenders only count 80 per cent of it to allow for vacancy and maintenance costs.

If you're carrying a car loan or personal debt, paying that down before you apply can increase what you're approved for. We regularly see officers who can borrow another $100,000 to $150,000 simply by clearing a $20,000 car loan first. The shift allowance and higher base income that WA Police receive helps, but the lender still applies the same serviceability rules. If borrowing capacity is tight, switching your owner-occupier loan to interest only temporarily can reduce your total monthly commitment and open up room for the investment loan.

Using Equity from Your Current Property

If your home has increased in value since you bought it, you can access that equity as a deposit for the investment property without needing to sell. The lender values your current property and lets you borrow up to 80 per cent of that figure across both loans. Anything above 80 per cent combined usually attracts LMI.

In a scenario like this, an officer bought in Ellenbrook four years ago and the property has gained around $80,000 in value. They owe $320,000 on a property now worth $480,000. At 80 per cent LVR they can borrow up to $384,000 against that property, which leaves $64,000 in usable equity. That's enough to cover a 10 per cent deposit and costs on a unit around $400,000. The equity is accessed by increasing the limit on the existing loan or by setting up a separate split, and the interest on that additional borrowing becomes deductible once it's used to fund the investment. For more on this approach, see equity release loans.

Proposed Tax Changes and What They Mean for Established Properties

From 1 July 2027, negative gearing on established residential properties will be restricted for any property purchased after 12 May 2026. Losses on these properties can only be offset against rental income or capital gains from residential property, not against your salary. Losses that can't be used in a given year carry forward. New builds are not affected and retain full negative gearing treatment.

If you're looking at an established property now, the change may reduce the after-tax benefit during the early years when the property is negatively geared. That doesn't make it a bad purchase, but it does mean your tax refund will be lower and you'll need more cash flow to cover the shortfall. Officers planning to buy before the change takes effect have until mid-2027 to settle, assuming the legislation passes as proposed. Properties purchased before 12 May 2026 are grandfathered and keep the existing treatment even if you hold them beyond 2027.

Variable Rate or Fixed Rate for an Investment Loan

Variable rates give you the flexibility to make extra repayments, redraw funds if the loan allows it, and avoid break costs if you need to refinance or sell. Fixed rates lock in your repayment amount for a set term, usually one to five years, which can help with budgeting but limit your ability to pay down the loan early without penalty.

For investment purposes, most officers choose variable because the ability to offset cash flow and access funds is worth more than rate certainty. If you're concerned about rate rises and the property is already tight on cash flow, a partial fix on half the loan can provide some stability without locking away all your flexibility. Switching between variable and fixed, or refinancing during a fixed term, can trigger break costs, so it's worth discussing your plans before committing.

Lenders Mortgage Insurance and How to Avoid It

LMI is charged when you borrow more than 80 per cent of the property value. On an investment loan, LMI is capitalised into the loan and the premium itself is tax deductible over five years. For a $400,000 property with a 10 per cent deposit, LMI might add $8,000 to $12,000 to your loan balance depending on your deposit size and lender.

Some lenders waive LMI for police officers up to 90 per cent LVR on investment properties, though the criteria are stricter than for owner-occupier loans. You'll generally need a clean credit file, stable income, and no other high-risk factors in your application. Where the waiver applies, it can reduce your upfront costs and avoid the need to save a larger deposit. More information on this can be found at LMI waivers for police officers.

When Not to Proceed with an Investment Purchase

If the property will be vacant for extended periods, or if the rental return doesn't cover at least 60 per cent of the loan repayment, the cash flow impact can be significant. Officers who are still in probation, carrying high personal debt, or planning to take extended leave in the next 12 months should consider waiting until their financial position is more stable.

A property that requires major repairs or strata work before it can be tenanted will delay your rental income and increase your out-of-pocket costs during the setup period. If you're borrowing close to your limit and have no buffer for vacancies or unexpected maintenance, you're one broken hot water system away from financial stress. The loan structure matters, but the property itself and your ability to hold it through the rough patches matter more.

Refinancing an investment loan when your circumstances change or when you find another lender offering lower rates can save you several thousand dollars a year in interest. The process is similar to refinancing your home loan, but you'll need updated rental statements and a current valuation. If your property has increased in value, refinancing your investment loan can also release additional equity for your next purchase or to pay down other debt.

Frequently Asked Questions

What deposit do I need for an investment property?

Most lenders require at least 10 per cent plus costs to avoid Lenders Mortgage Insurance, though some accept less if you meet their criteria. You can also use equity from your existing home instead of cash savings.

How does negative gearing change from 2027?

From 1 July 2027, losses on established residential properties purchased after 12 May 2026 can only be offset against rental income or residential capital gains, not against your salary. New builds retain full negative gearing treatment.

Can I borrow for an investment property if I already have a home loan?

Yes, lenders assess both loans together and include 80 per cent of your expected rental income in their serviceability calculation. Your existing home loan repayments and other debts are also factored in.

Should I choose interest only or principal and interest?

Interest only keeps repayments lower for up to five years and suits officers managing variable income or planning to sell within a few years. Principal and interest builds equity faster and is better for long-term holds.

Do investment loans have higher rates than owner-occupier loans?

Yes, investment loans typically attract a rate 0.4 to 0.5 percentage points higher because lenders treat them as higher risk. However, the interest is tax deductible, which offsets much of the difference.
