Beginner's guide to Investment Loans and Property Goals

Investment property finance works differently depending on what you're trying to achieve. A government employee looking to replace income in retirement needs a different loan structure than someone focused on capital growth or portfolio expansion.

The key to getting the right investment loan is matching the product features to your specific goal, not just finding the lowest advertised rate. Your employment in the WA public service gives you income stability that lenders value, which can open up certain loan features that might be less accessible to other borrowers.

What Investment Loan Features Actually Matter for Different Goals

If you're buying an investment property to generate passive income during retirement, you'll want a loan structure that allows you to pay down debt while rental income covers most or all of your repayments. That typically means choosing a principal and interest loan with a variable rate, so you can make extra payments without restriction and reduce the loan balance before you stop working.

Consider a WA Government employee in their late 40s purchasing a three-bedroom unit in Cannington. The property is close to the train station and Carousel shopping centre, which keeps vacancy rates low. Rental income is $550 per week. They take out a principal and interest loan at a standard variable rate with full offset and unlimited extra repayments. They funnel their offset account savings and occasional lump sums into the loan. Over 15 years, they reduce the loan balance significantly while the property appreciates, and by retirement, rental income covers the remaining repayment with minimal debt left.

If your goal is to build a portfolio across multiple properties, you'll likely prioritise interest-only periods and offset accounts. Interest-only investment loans allow you to keep repayments lower while preserving cash flow and borrowing capacity for the next purchase. You're not paying down the loan, but you're holding equity that can be used to fund subsequent deposits. An offset account linked to the loan lets you park savings and reduce interest charges without locking funds into the loan itself, which keeps your liquidity intact for future opportunities.

How Loan to Value Ratio Affects Your Borrowing and LMI Costs

Your deposit size directly affects your loan to value ratio, which determines whether you'll pay Lenders Mortgage Insurance. For investment property finance, most lenders will lend up to 90% of the property value, but anything above 80% typically triggers LMI.

As a WA Government employee, you may have access to LMI waivers depending on your role, income, and the lender. Some lenders waive LMI up to 90% LVR for public servants, which can save several thousand dollars and allow you to enter the market or expand your portfolio without needing a 20% deposit.

If you're borrowing at 85% LVR on a $500,000 investment property without an LMI waiver, you might pay between $8,000 and $12,000 in insurance premiums. That cost is either paid upfront or capitalised into the loan amount. If your employer qualifies you for a waiver, that entire cost disappears, which changes the upfront cash you need and the total interest paid over the life of the loan.

Variable Rate vs Fixed Rate for Property Investors

A variable interest rate gives you flexibility to make extra repayments, access offset accounts, and redraw funds without penalty. Most investors prefer variable rates because rental income and tax settings can change, and the ability to adjust repayment strategy without break costs is worth more than rate certainty.

Fixed rates lock in your repayment amount for a set period, usually between one and five years. That can be useful if you're managing cash flow tightly or if you expect rates to rise, but fixed investment loans typically don't allow extra repayments beyond a small annual threshold, and offset accounts are often unavailable. If you need to refinance or sell before the fixed term ends, break costs can run into thousands of dollars.

Some investors split their loan between variable and fixed portions to get partial rate protection while keeping some flexibility. That approach works if your priority is certainty on part of the repayment while still being able to make lump sum payments on the variable portion.

Interest Only vs Principal and Interest Repayment Structures

Interest-only investment loans let you pay only the interest charged each month, without reducing the principal. That keeps your repayment lower and frees up cash flow for other expenses, additional property purchases, or offset account savings. Most interest-only periods last between one and five years, after which the loan converts to principal and interest unless you negotiate an extension.

If your goal is to hold the property long term and eventually pay it off, principal and interest repayments are the better structure. You're reducing the debt each month, which lowers your total interest cost and increases your equity. Rental income might not cover the full repayment initially, but as rents increase and the loan balance falls, the gap closes.

Interest-only structures suit investors who plan to sell before the loan term ends, or who want to preserve borrowing capacity to acquire additional properties. Principal and interest suits those building wealth through debt reduction and rental income, particularly if the property is intended to support retirement income.

How the 2027 Budget Changes Affect New Investment Property Purchases

If you bought an established investment property before 13 May 2026, your arrangements remain unchanged. If you're buying an established residential property from that date onwards, two significant changes take effect from 1 July 2027.

The 50% capital gains tax discount will be replaced with a discount based on inflation and a minimum 30% tax on gains. Losses from the property, such as when your interest and expenses exceed rental income, will only be deductible against rental income or capital gains from residential property, not against your salary.

Those changes don't apply to new builds, which still qualify for the 50% CGT discount and full negative gearing. If you're purchasing an investment property and your goal is to maximise tax deductions in the early years, a new or newly completed property might deliver better tax outcomes than an established one, particularly if you're in a higher tax bracket.

The deductions you can't claim against salary can still be carried forward and used against future rental income or capital gains, so they're deferred rather than lost. That makes established investment properties less attractive for high-income earners focused on immediate tax benefits, but still viable for those prioritising capital growth or long-term income.

Claimable Expenses and Rental Income Considerations

Rental income is assessable, and most costs associated with holding the property are claimable. That includes loan interest, body corporate fees, council rates, insurance, property management fees, repairs, and depreciation on certain fixtures and fittings.

If the property is vacant, you can still claim expenses during that period, but lenders will assess your ability to service the loan assuming some level of vacancy when you apply. Most lenders apply a vacancy rate assumption of around 4% to 6% when calculating your borrowing capacity, even if the property has a tenant in place.

Stamp duty is payable when you purchase the property, and it's calculated on the purchase price. In Western Australia, stamp duty on a $500,000 investment property is around $17,765. That's an upfront cost that can't be added to the loan, so it needs to come from savings or other sources. Unlike interest and ongoing costs, stamp duty isn't claimable as a deduction, but it does form part of your cost base for capital gains tax purposes when you sell.

Using Equity from Your Home to Fund Investment Property Deposits

If you already own a home and have built up equity, you can use that equity to fund the deposit on an investment property without selling or saving additional cash. Lenders allow you to borrow against the equity in your home, either by refinancing your existing loan or taking out a separate loan secured against the property.

This is common among public service employees who have owned a home for several years and want to enter the investment market without liquidating other assets. You'll need to leave at least 20% equity in your home after the release to avoid paying LMI on that property, and the total borrowing across both properties needs to fit within your serviceability.

For guidance on how to structure equity release and what that means for your overall borrowing, take a look at the page on equity release loans. The process involves a valuation, a new loan application, and careful consideration of how much debt you're comfortable holding across multiple properties.

Choosing the Right Investment Loan Application Strategy

Your loan application will be assessed on your income, existing debts, living expenses, and the rental income the property is expected to generate. Lenders typically assess rental income at 80% of the full amount to account for vacancy and management costs, so if the property generates $500 per week, the lender will use $400 per week in their serviceability calculation.

If you're applying for your first investment loan, lenders will want to see genuine savings, a clear deposit source, and stable employment. WA Government employees generally meet the employment stability requirement without issue, which can make the application process more predictable than it is for contract or casual workers.

If you're expanding an existing portfolio, lenders will assess your current investment properties, their rental income, and the debt attached to them. Borrowing capacity can tighten as you add more properties, even if each one is positively geared, because lenders apply serviceability buffers that assume rate rises and income changes.

Refinancing Investment Loans to Improve Rate or Structure

Refinancing an investment property loan makes sense if your current rate is significantly higher than what's available elsewhere, or if your loan structure no longer matches your goals. Switching from interest-only to principal and interest, adding an offset account, or consolidating multiple investment loans into one facility are all common reasons to refinance.

Refinancing involves a new application, a property valuation, and discharge fees from your existing lender. The new lender will assess your current income and serviceability just as they would for a new purchase. If your circumstances have changed since you took out the original loan, such as a pay rise, additional properties, or reduced living expenses, refinancing can also increase your borrowing capacity.

If you're holding multiple investment properties and your goals have shifted from acquisition to debt reduction, refinancing to a lower rate with principal and interest repayments can save tens of thousands in interest over the remaining loan term. More detail on that process is available on the investment loan refinancing page.
