Your first investment property loan works differently from the home loan you may already have.
Lenders treat investment borrowing as higher-risk lending, which means they apply stricter serviceability tests, often require larger deposits, and price the loan differently. If you're a Truganina resident looking to build wealth through property, understanding these differences before you start your search will help you know what you can borrow and which properties are within reach.
Deposit requirements sit higher for investor borrowing
Most lenders require a minimum 10 per cent deposit for an investment property, compared to 5 per cent for owner-occupiers. Many apply lower loan-to-value ratio limits for investors, capping lending at 90 per cent or 95 per cent of the property value depending on your circumstances. If you borrow above 80 per cent of the property value, you'll pay Lenders Mortgage Insurance, which protects the lender if you default. The premium is calculated on the loan amount and LVR, and it's a one-time cost you can either pay upfront or add to your loan.
Some lenders will let you use equity in your existing Truganina home as your deposit rather than cash savings. This approach, sometimes called equity release or leveraging equity, can help you enter the investment market sooner, but it increases the total debt secured against your home. We regularly see first-time investors surprised by how much usable equity they actually have, particularly if they've owned their home for several years in a suburb where values have climbed.
Serviceability is tested at a rental income discount
Lenders assess your ability to repay an investment loan by adding the proposed loan repayments to your existing commitments and measuring that total against your income. They'll include rental income from the investment property in your income calculation, but they don't count all of it. Most lenders apply a haircut, typically 20 per cent, to allow for vacancy periods, maintenance costs, and property management fees. So if the property you're considering would rent for $500 per week, the lender will only credit you with $400 per week in income.
Every lender also tests your serviceability at a rate that's roughly 3 percentage points above the actual loan rate, a buffer set by the Australian Prudential Regulation Authority. That buffer has been in place since late 2021 and applies to all new borrowing. If you're looking at a variable rate investor loan currently priced around 6.5 per cent, the lender will assess whether you can afford repayments at around 9.5 per cent.
Debt-to-income limits also apply. Since early 2026, banks can only lend up to 20 per cent of their new investor loans to borrowers with total debts of six times their gross income or more. If your household income is $100,000 and your existing mortgage and investment loan would push your total debt above $600,000, some lenders may decline your application even if you meet all other criteria.

Interest-only repayments reduce cash flow pressure early on
Most investors choose an interest-only repayment structure for the first few years of the loan. Instead of paying down both the interest and the loan balance, you only pay the interest charged each month. This keeps your repayments lower and can improve cash flow, particularly if the property is negatively geared (where your rental income is less than your holding costs including interest, rates, insurance and property management).
Interest-only periods typically run for one to five years, after which the loan reverts to principal and interest repayments unless you apply to extend the interest-only term. Not all lenders will extend beyond five years, and those that do may apply stricter conditions. Once the loan switches to principal and interest, your repayments will jump noticeably because you're paying down the loan balance as well as covering the interest.
You can still make extra repayments during an interest-only period if you want to reduce the loan balance sooner, but most investors prefer to direct spare cash toward saving for their next deposit or offsetting other debts. One thing to note is that under current lending rules, long-term interest-only loans above 80 per cent LVR attract higher risk weighting if the interest-only period isn't clearly defined or exceeds five years, which can affect pricing.
Variable and fixed rates serve different investment strategies
Most investment loan products are available on either a variable rate or a fixed rate, and some lenders allow you to split your loan across both. Variable rates move up and down with the market, which means your repayments can change, but you'll generally have access to features like offset accounts and the ability to make extra repayments without penalty.
Fixed rates lock in your interest cost for a set period, usually one to five years, which can help with budgeting and protect you if rates rise. The downside is less flexibility. Many fixed rate products don't allow offset accounts, cap extra repayments, and charge break costs if you pay out the loan or refinance before the fixed term ends.
Consider a buyer who already owns a home in Truganina and is looking to purchase a two-bedroom unit in Tarneit as a first investment. They have $80,000 in usable equity and want to borrow $420,000. They're concerned about rate rises but also want the option to use an offset account to park rental income and reduce interest. In this scenario, splitting the loan (say, 60 per cent variable with an offset and 40 per cent fixed) provides both rate protection and flexibility. It's not the right structure for everyone, but it suits an investor who wants some certainty without giving up all the features that help manage cash flow.
Truganina's proximity to employment hubs supports rental demand
Truganina sits roughly 22 kilometres west of Melbourne's CBD, bordered by the Western Freeway, Forsyth Road, and Skeleton Creek. The suburb has grown quickly over the past decade, driven by new estate developments and its position between Werribee employment areas to the south and the Deer Park industrial precinct to the north. The area attracts a mix of young families and essential workers looking for newer housing stock within reach of distribution centres, manufacturing, and logistics businesses along the Western Ring Road corridor.
Rental demand in Truganina is supported by that employment base and by the suburb's access to Tarneit and Williams Landing train stations, both within a short drive. Investors often look at newer three- and four-bedroom houses on compact blocks, which appeal to families who want modern homes and can't yet afford to buy. Vacancy rates across the broader Wyndham local government area have been low in recent years, though investors should always factor in a buffer when calculating expected returns.
When you're looking at a specific property, check how far it sits from the nearest train station, shopping centre, and primary school. Tenants in this part of Melbourne tend to prioritise those three things, and properties that require two cars to function will have a smaller pool of renters.
Tax treatment depends on when you buy and what you buy
If you purchase an established investment property after mid-May 2026, the tax treatment of any loss you make on the property will change from the 2027-28 financial year onward. Losses will only be deductible against income from other residential properties, including capital gains when you sell, rather than against your salary or wage income. Losses you can't use in a given year can be carried forward.
Properties you already owned at mid-May 2026, or properties you've exchanged contracts on by that date, continue to be fully negatively geared against all income until you sell. Newly built properties also retain full negative gearing, which means if you're buying your first investment property now, a new build or a property classified as an eligible new build under the legislation may deliver better tax outcomes over time.
Negative gearing is not the only reason to invest in property, but for buyers in Truganina who are still in the wealth-building phase and earning a salary, the ability to offset holding costs against other income can make the difference between positive and negative cash flow in the early years. If you're considering an established property purchased after the cut-off date, model your cash flow assuming you won't be able to claim losses against your wage income from the 2027-28 year onward.
Refinancing your investment loan keeps your rate in check
Investor interest rates are typically higher than owner-occupier rates, and lenders often reserve their sharpest discounts for new customers. That means the rate you start on may not stay optimal two or three years down the track. Refinancing your investment loan to a more suitable product or a lender offering a lower rate can reduce your interest cost and improve your cash flow, particularly if you've built equity in the property or your financial position has strengthened since you first borrowed.
Refinancing also gives you a chance to reassess your loan structure. You might want to switch from interest-only to principal and interest, or vice versa. You might want to access equity to fund your next purchase. Or you might simply want to move to a lender that allows offset accounts on investment loans where your current lender does not. Each of those changes can be managed through a refinance.
If your loan is on a fixed rate, check whether break costs apply before you move. Break costs are calculated based on the difference between your fixed rate and the lender's current cost of funds, and they can sometimes exceed the benefit of refinancing. If your fixed term is close to ending, it's usually worth waiting.
Your next step is a borrowing capacity assessment
Before you start attending inspections or making offers, you need to know how much you can actually borrow for an investment property. That figure will be different from what you could borrow as an owner-occupier, and it will depend on your income, existing debts, living expenses, and the rental income the property is expected to generate.
Call one of our team or book an appointment at a time that works for you.

Frequently Asked Questions
What deposit do I need for my first investment property loan?
Most lenders require a minimum 10 per cent deposit for an investment property, though some will lend up to 95 per cent of the property value in certain circumstances. If you borrow above 80 per cent LVR, you'll pay Lenders Mortgage Insurance. You can also use equity in your existing home as your deposit.
How do lenders assess rental income on an investment loan?
Lenders include rental income in your serviceability assessment but apply a discount, typically 20 per cent, to account for vacancy, maintenance, and management costs. If the property would rent for $500 per week, the lender will usually only credit you with $400 per week.
Can I still negatively gear an investment property purchased now?
If you purchase an established property after mid-May 2026, losses will only be deductible against other residential property income from the 2027-28 financial year onward. Newly built properties and properties owned before mid-May 2026 retain full negative gearing against all income.
Should I choose interest-only or principal and interest repayments?
Most first-time investors choose interest-only repayments for the first few years to keep cash flow manageable, particularly if the property is negatively geared. The loan will revert to principal and interest after the interest-only period ends, and your repayments will increase at that point.
Why are investor interest rates higher than owner-occupier rates?
Lenders treat investment loans as higher risk because borrowers are more likely to prioritise their own home over an investment property during financial stress. That higher risk is reflected in both the interest rate and the serviceability requirements applied to investor borrowing.
