Buying Your First Investment Property in NSW: A Guide
By Fay
Buying your first investment property is a different process from buying the home you live in. The deposit rules differ, the loan structure matters more than most people expect, and the costs go well beyond the purchase price. Here is what to work through before you start browsing listings.
What Do You Want the Property to Do for You?
Before looking at a single listing, it is worth being clear on your goal. Are you after long-term capital growth, a property that generates rental income to help cover its own costs, or somewhere that a family member might live in one day? There is no right or wrong answer, but your goal affects the type of property you buy, where you buy, and how your loan should be set up. Getting this clear at the start saves a lot of confusion later.
How Much Deposit Do You Need for an Investment Property?
As of October 2026, most lenders prefer a 20% deposit for an investment property. Putting down 20% also avoids Lenders Mortgage Insurance (LMI). Some lenders will accept less, often 10% or sometimes lower, but you will usually pay LMI and may face a higher interest rate.
On top of the deposit, your budget needs to cover:
Legal and conveyancing fees
Loan costs
One thing that catches many people off guard: first home buyer stamp duty concessions generally do not apply to investment properties, so stamp duty can be a significant upfront amount. You can estimate it using the Stamp Duty Calculator at themortgagemum.com.au.
Can You Use Equity in Your Home Instead of a Cash Deposit?
If you already own your home, you may not need to save a separate cash deposit at all. Many first-time investors use the equity they have built up in their home to fund the deposit and buying costs on an investment property.
Usable equity is generally calculated as up to 80% of your home's current value, minus what you still owe on it. As of October 2026, and subject to lender criteria, that figure works as follows: if your home is worth $900,000 and you owe $500,000, your usable equity could be around $220,000. That is $900,000 multiplied by 80%, giving $720,000, minus the $500,000 still owing.
That equity can often cover the deposit and purchase costs, while the remainder is borrowed against the new investment property. How this is structured matters considerably, which is worth thinking through carefully before you proceed.
Why Does Loan Structure Matter So Much from Day One?
Loan structure is the part most first-time investors do not think about until it is too late. A few principles that are worth understanding:
Keep investment debt separate from your home loan. Separate loan accounts make it much easier to track what was borrowed for what purpose, which your accountant will appreciate.
Avoid cross-securing your properties where possible. When two properties secure one loan, selling or refinancing one of them can become harder because the lender has a say over both.
Think about interest-only versus principal and interest. Interest-only repayments are lower during the interest-only period, but your loan balance does not reduce and repayments rise once that period ends. It suits some strategies and not others.
Consider where your offset account sits. Many investors keep savings in an offset account linked to their home loan rather than the investment loan, but the right setup depends on your individual circumstances.
The tax treatment of investment loans is a question for your accountant. It is worth having that conversation before you buy, not after.
How Do Lenders Assess a First-Time Investor?
Lenders look at investment loan applications a little differently from owner-occupier applications. A few things to be aware of:
Rental income is shaded. Lenders usually count only a portion of the expected rent, often around 70 to 80% as of October 2026, to allow for vacancies and ongoing costs.
You are tested at a higher rate. Lenders check that you could still afford repayments if interest rates rose, so your borrowing capacity is assessed against a higher rate than the one you will actually pay.
Investor rates are often higher than owner-occupier rates, and interest-only rates are often higher again.
Policies vary between lenders. Some lenders are more generous with rental income or existing debts than others, which is one reason borrowing capacity can differ substantially depending on who you apply with.
The Borrowing Power Calculator at themortgagemum.com.au gives a rough starting point. A pre-approval tells you what a lender is actually prepared to lend.
What Ongoing Costs Do First-Time Investors Often Forget?
The purchase price and loan repayments are only part of the financial picture. Make sure your budget also includes:
Property management fees
Landlord insurance and building insurance
Council rates, water rates, and for units, strata levies
Land tax, which applies in most states once your total landholdings pass a threshold and is calculated separately in each state
Repairs and maintenance
Periods when the property is vacant
Keeping a cash buffer for these is sensible. One quiet month or one broken hot water system should not become a financial stressor on top of everything else.
Should You Buy in a Different State to Where You Live?
Many investors live in one city and buy in another. For example, living in Sydney and buying in Brisbane or Melbourne. That can work well, but there are a few practical points to keep in mind:
Stamp duty and land tax rules differ by state, so make sure your budget reflects the rules of the state where you are buying.
Lender policies can vary by location and property type, for example for small apartments or properties in certain postcodes.
Get local help: a building and pest inspector, a conveyancer or solicitor registered in that state, and a reliable local property manager.
A Quick Checklist Before You Start
Working through these steps before you look at properties puts you in a much stronger position:
Be clear on your goal for the property.
Work out your deposit, or calculate your usable equity.
Get your borrowing capacity checked and a pre-approval in place.
Talk to your accountant about loan structure and tax before you buy.
Budget for all the ongoing costs, plus a cash buffer.
Research the area and property carefully, with local help if you are buying interstate.
Set up your loans so this purchase does not make the next one harder.
