Everything You Need to Know About Investment Property Loans

Choosing an Investment Property in Scarborough Starts with Your Loan Structure

Your property choice and your loan structure need to be decided together, not separately. Most Scarborough investors pick the property first and then look for finance, which can mean they miss out on features like offset accounts or interest-only periods that would have changed which property made financial sense.

Scarborough sits between the Indian Ocean and West Coast Highway, with a mix of older apartment blocks near the beachfront and townhouse developments closer to Osborne Park. Rental demand is high year-round from young professionals working in the city and families wanting coastal access without the price tag of Cottesloe or City Beach. That demand matters when you're structuring a loan, because consistent rental income keeps your serviceability stable and your lender comfortable.

Does Your Deposit Size Change Which Property Type You Should Target?

Yes. The amount you can put down directly affects which property types will work with your borrowing capacity and whether you'll need to factor in additional costs like Lenders Mortgage Insurance.

Consider an investor with access to equity in their current home who can put down 20 per cent. That level keeps them clear of LMI and opens up both established apartments and townhouses. In our experience, investors with smaller deposits who need LMI often focus on newer properties where the rental yield and potential for value growth justify the upfront premium. A two-bedroom apartment close to the Scarborough Beach Pool precinct might rent reliably, but if you're paying LMI and body corporate fees, the numbers need to stack up against an alternative like a villa closer to Innaloo that might have lower strata costs.

An investor targeting an established unit near the esplanade with a 15 per cent deposit would face LMI, which gets added to the loan or paid upfront. That cost changes the weekly holding cost and the point at which rental income starts to cover expenses. If the rental return doesn't justify the additional outlay, a different property or a larger deposit might be the better call.

Interest-Only Versus Principal and Interest for New Investors

Interest-only loans reduce your repayments during the interest-only period, which can improve short-term cash flow and make it easier to hold the property during vacancies or maintenance periods.

Most lenders offer interest-only periods of one to five years on investment loans. During that time, you're only paying the interest portion, so your repayments are lower than they would be on a principal and interest loan. Once the interest-only period ends, the loan reverts to principal and interest repayments, and the monthly cost increases.

In a scenario where an investor is holding a property in Scarborough and working full-time in Perth CBD, an interest-only period gives breathing room to manage cash flow without needing to draw on savings every month. The trade-off is that you're not reducing the loan balance during that period, so your equity only grows if the property value increases. If you're planning to sell within a few years or use the equity for further purchases, that might suit. If you're holding long-term and want to reduce debt, principal and interest from the start will get you there faster.

Variable or Fixed Rates for Rental Properties

Variable rates give you flexibility to make extra repayments, access offset accounts and refinance without penalty. Fixed rates lock in your repayment amount for a set period, which helps with budgeting but limits your options if your situation changes.

Most Scarborough investors we work with choose variable rates or a split structure. Variable loans typically come with offset accounts, which let you park rental income or savings against the loan balance and reduce the interest charged. That feature is useful if you're managing rental income separately or if you have irregular cash flow from other sources. Fixed rates don't usually offer offset accounts, and if you need to break the fixed term early, you may face break costs.

A split loan gives you part fixed and part variable. For example, you might fix 50 per cent of the loan for three years to lock in part of your repayment, and leave the other 50 per cent variable with an offset account. That approach spreads the risk across rate movements and keeps some flexibility in place.

How Rental Income Affects Your Borrowing Power

Lenders will include a portion of your expected rental income when they assess your ability to service an investment loan, but they don't count every dollar.

Most lenders apply a shading factor of around 80 per cent to rental income, meaning they assume you'll receive 80 per cent of the expected rent to account for vacancies, maintenance and periods between tenants. Some lenders are more conservative and shade rental income at 70 per cent. The shading affects how much you can borrow, especially if you're relying on rental income to meet serviceability.

Scarborough's proximity to the beach and public transport means vacancy rates are typically lower than outer suburbs, but lenders still apply the same shading. If you're expecting rental income to cover most of your repayments, the shaded amount needs to meet serviceability tests alongside your other income and expenses. If it doesn't, you may need to increase your deposit, reduce the loan amount or adjust your property target.

Leveraging Equity from Your Home to Fund a Scarborough Investment

If you own property already, you can use the equity in that property as your deposit without needing to sell or save additional cash.

Equity is the difference between what your property is worth and what you owe on it. Lenders will typically let you borrow up to 80 per cent of your property's value without needing LMI, which means if your home is valued higher than your current loan balance, that difference can be used as security for an investment purchase. You'll need a valuation, and the lender will assess your serviceability across both loans.

An investor holding a home in a northern suburbs location with strong value growth over the past few years might have significant equity available. Rather than saving a deposit from income, they can access that equity through a refinance or top-up and use it to fund the deposit and purchase costs on a Scarborough property. The risk is that you're increasing your overall debt, so serviceability across both properties needs to be solid. If rental income drops or interest rates rise, you're carrying repayments on two loans, and both need to be manageable within your budget.

Tax Treatment and Deductibility After Recent Changes

Interest on investment loans is generally deductible against rental income, but recent legislation has changed how losses are treated depending on when you purchase.

For properties purchased before May 2026, rental losses can still be deducted against your total income, including salary. For established properties purchased after that date, losses can only be offset against income from other residential properties, not against wages. New builds purchased after May 2026 remain fully deductible. The rules also change how capital gains are taxed from mid-2027 onward, with indexation replacing the discount method for gains accruing after that date.

Those changes affect the cash flow and after-tax return on any Scarborough property you're considering now. If you're buying an established apartment or townhouse, you won't be able to offset rental losses against your salary, which means the property needs to be closer to neutral or positively geared from the start. If you're looking at a new development, the old negative gearing rules still apply, which can improve your cash position during the early years when expenses are higher.

Loan Features That Matter for Property Investors

Offset accounts, redraw facilities and the ability to make extra repayments all affect how you manage cash flow and interest costs over the life of the loan.

An offset account is a transaction account linked to your loan. Any balance in the offset reduces the amount of interest you're charged without locking the funds away. That feature is valuable if you're holding rental income, tax refunds or savings that you might need access to. Redraw facilities let you make extra repayments and then withdraw them later, but some lenders place conditions on redraw, and accessing funds isn't always instant.

For Scarborough investors managing rental income from a beachside unit, an offset account means that income can sit in the offset between expense payments and reduce interest in the meantime. If you don't have an offset and you're parking rental income in a separate savings account, you're paying interest on the full loan balance and earning minimal interest on the savings. Over time, that difference adds up.

Choosing Between Established and New Builds in Scarborough

Established properties near the beachfront or around Scarborough Beach Road offer immediate rental appeal and established infrastructure, but come with body corporate fees and older building stock. New developments closer to the Karrinyup boundary or Innaloo offer depreciation benefits and lower maintenance in the early years, but may face higher initial purchase prices.

Depreciation is a non-cash deduction that reduces your taxable income. Newer properties have higher depreciation schedules because fixtures, fittings and building components can be written off over time. Established properties have lower depreciation, especially if they were built before recent tax changes that restricted plant and equipment depreciation for second-hand assets.

If you're weighing an older two-bedroom unit close to the esplanade against a newer townhouse development near Glendalough station, the older unit will likely have lower purchase costs and potentially lower body corporate fees, but the depreciation benefit will be smaller. The newer townhouse will offer higher depreciation, which improves your after-tax return, but may have higher upfront costs and strata levies during the early years. Your loan structure and tax position will determine which property delivers stronger returns over your intended holding period.

What Lenders Look for in Investment Loan Applications

Lenders assess your income, existing debts, living expenses and the rental income from the property you're buying. They also apply a serviceability buffer, currently set at 3 percentage points above the loan rate, to ensure you can still afford repayments if rates rise.

That buffer means even if you're borrowing at a rate around current variable levels, the lender is testing your ability to service the loan at a rate 3 per cent higher. If you're carrying other debts like car loans, personal loans or credit card limits, those commitments reduce your borrowing capacity. Lenders will also account for your living expenses, either by using your declared expenses or applying a benchmark like the Household Expenditure Measure.

Debt-to-income limits also apply. From early 2026, lenders can only write up to 20 per cent of new investor loans to borrowers with total debt more than six times their gross income. If your total borrowing across all loans exceeds that threshold, you may fall into the portion of lending that's capped, which can mean a lower approved amount or a decline unless your income or deposit increases.

When to Consider Refinancing an Investment Loan

Refinancing can give you access to lower rates, better loan features or additional equity as your property value increases. It's worth reviewing your loan whenever your circumstances change or when your current loan no longer suits your strategy.

Investors often refinance to access equity for further purchases, to move from interest-only back to principal and interest, or to switch lenders for a lower rate or offset account. If your Scarborough property has increased in value since purchase, refinancing lets you access that equity without selling. If your income has increased or your other debts have reduced, you may also qualify for a larger loan or different loan structure.

Refinancing does come with costs, including discharge fees from your current lender, application fees with the new lender and sometimes valuation costs. Those costs need to be weighed against the benefit you're gaining. If you're refinancing to access equity and fund a second purchase, the cost is usually justified. If you're refinancing purely for a small rate reduction, the saving needs to outweigh the fees.

Working with a Mortgage Broker on Investment Property Selection

A broker can show you how different loan structures affect which properties make sense, and which lenders will support the type of property and strategy you're considering.

Not every lender will finance every property type. Some lenders have restrictions on high-rise apartments, others have postcode restrictions or limits on interest-only lending. A broker has access to investment loan options from banks and lenders across Australia and can match your deposit, income and property target to the lenders most likely to approve and offer competitive terms.

For Scarborough investors, that might mean identifying lenders comfortable with beachfront apartments, lenders offering higher LVRs on new builds, or lenders with offset accounts and flexible repayment options. It also means structuring the loan in a way that keeps your options open if you want to build a portfolio, release equity later or adjust your repayment strategy as your income or property values change.
