Everything You Need to Know About Investment Loans

If you're considering buying an investment property in Mount Lawley or nearby suburbs, the loan you choose will shape your cash flow, tax position, and ability to grow your portfolio over time.

The right investment loan structure depends on whether you're holding the property for capital growth, generating passive income, or both. Mount Lawley's proximity to the CBD, established character homes, and consistent rental demand make it a popular choice for investors, but the recent changes to negative gearing and capital gains tax announced in the Federal Budget mean your loan setup now carries more weight than it used to.

What Makes an Investment Loan Different from a Home Loan

An investment loan is assessed differently because the property generates rental income and carries different tax treatment. Lenders consider the rental yield, vacancy rate, and your ability to service the loan even when the property isn't tenanted. Most lenders apply a rental income assessment of around 70% to 80% of the expected rent, which means you'll need enough personal income or equity to cover the shortfall.

Interest rates on investment loans are typically slightly higher than owner-occupier rates, usually by around 0.10% to 0.30%, depending on the lender and loan structure. This reflects the higher risk lenders attach to investment lending. Your deposit size also matters. While you can borrow with a 10% deposit, you'll pay Lenders Mortgage Insurance (LMI) on any loan above 80% loan to value ratio. In Mount Lawley, where established properties in the heritage precinct often attract premium prices, a 20% deposit can make a meaningful difference to your upfront costs and ongoing repayments.

Interest Only vs Principal and Interest Repayments

Interest only repayments let you pay just the interest portion of the loan for a set period, usually one to five years. This keeps your repayments lower and frees up cash flow, which can help if you're relying on rental income or planning to use surplus funds to pay down your home loan or invest elsewhere.

Consider an investor who bought a two-bedroom villa in Mount Lawley with a loan amount of $600,000 at a variable interest rate. On interest only, the monthly repayment sits at roughly half what it would be on principal and interest over 30 years. That difference might be directed toward their owner-occupied mortgage or held in an offset account. Once the interest only period ends, the loan reverts to principal and interest unless you negotiate a new term, and the repayment increases accordingly.

Principal and interest repayments reduce the loan balance over time, which builds equity and lowers risk. If you're planning to hold the property long term and want to eventually own it outright, this structure makes sense. It also gives you more refinancing options down the track, since your loan to value ratio improves as you pay down the balance.

How the 2027 Tax Changes Affect Your Loan Strategy

From 1 July 2027, negative gearing deductions on established residential properties purchased after 12 May 2026 will only be claimable against rental income or capital gains from residential property, not against salary or wages. If you bought an investment property in Mount Lawley before Budget night, your existing arrangements remain unchanged.

For properties acquired after that date, any loss you make on the property can still be carried forward and claimed against future rental income or when you sell, but it won't reduce your taxable income in the year you incur it. This shifts the appeal of interest only loans for some investors, particularly those who were using negative gearing to reduce their annual tax bill. If you're no longer able to offset losses against your salary, holding a higher loan balance on interest only may not deliver the same tax outcome it once did.

The capital gains tax discount is also changing. Instead of the current 50% discount, gains will be indexed for inflation and subject to a minimum 30% tax. New builds retain the option to use the 50% discount, which makes them more attractive from a tax perspective if you're planning to sell within a decade or two.

Variable Rate, Fixed Rate, or a Split Loan Structure

A variable rate loan moves with the market, which means your repayments can increase or decrease depending on what the Reserve Bank and your lender do with rates. Most variable rate investment loans come with features like offset accounts and the ability to make extra repayments without penalty, which can be useful if you want flexibility or plan to refinance later.

Fixed rate loans lock in your interest rate for a set period, usually one to five years. This gives you certainty around repayments, which can help with budgeting if rental income is tight or you're managing multiple properties. The downside is less flexibility during the fixed term, and if you want to exit early or make large extra repayments, you may face break costs.

Some investors split their loan between fixed and variable, which lets them lock in part of the repayment while keeping access to features like an offset account on the variable portion. In our experience, this works well when you're uncertain about rate movements or want to balance security with flexibility.

Using Equity to Fund Your Deposit

If you already own a home in Mount Lawley or a nearby suburb, you may be able to use the equity in that property to fund your deposit rather than drawing on cash savings. Lenders typically allow you to borrow up to 80% of your home's value without paying LMI, so if your property has increased in value since you bought it, that equity can be released and directed toward your investment purchase.

As an example, if your home is valued at $900,000 and you owe $400,000, you have $500,000 in equity. At 80% lending, you could access up to $320,000 in usable equity, which would cover a deposit and purchase costs on an investment property without needing to sell or save additional funds. This is a common approach for investors building a portfolio, but it does increase your overall debt, so serviceability becomes important. Your broker can run the numbers based on your income, existing commitments, and the rental income from the property you're buying.

Loan Features That Matter for Property Investors

Not all investment loan products are the same. An offset account linked to your variable rate loan can reduce the interest you pay without affecting your ability to claim deductions, since the loan balance stays the same. If you're holding surplus rental income or savings, parking it in an offset can save you thousands over the life of the loan.

Some lenders offer interest rate discounts for investors with larger deposits or those refinancing from another lender. Rate discounts of 0.20% to 0.50% are not uncommon, and they add up over time. Portability is another feature worth considering if you plan to sell and reinvest, as it lets you transfer your loan to a new property without reapplying or paying discharge fees.

Redraw facilities let you access extra repayments you've made, but the tax treatment can be complex if you're pulling money out for non-investment purposes, so it's worth speaking to an accountant before using this feature.

What Lenders Look at When Assessing Your Investment Loan Application

Lenders assess your borrowing capacity based on your income, existing debts, living expenses, and the rental income the property will generate. Most lenders apply a serviceability buffer, which means they test whether you can still afford the loan if interest rates rise by 2% to 3%. They also assess rental income at a discounted rate to account for vacancy periods and potential rent fluctuations.

If you're self-employed or earn variable income, you'll generally need to provide two years of tax returns and financials. If you're salaried, recent payslips and a letter from your employer are usually enough. Your borrowing capacity will also be affected by any other investment properties you own, personal loans, credit card limits, and even buy now, pay later accounts.

Body corporate fees are factored into the assessment if you're buying a villa or apartment, and lenders want to see that strata records are in order. In Mount Lawley, many character conversions and older villa complexes have lower body corporate fees compared to newer developments, which can improve your serviceability.

When Refinancing Your Investment Loan Makes Sense

Refinancing can reduce your interest rate, access equity for further investment, or switch your loan structure as your circumstances change. If you've been on the same rate for more than two years, or if your loan to value ratio has improved due to property value growth or repayments, you may be able to negotiate a lower rate or access features your current loan doesn't offer.

Investors often refinance to consolidate debt, release equity, or move from interest only to principal and interest as they approach retirement. A loan health check can help you understand whether your current loan still fits your strategy or whether there are better options available now.
