You buy an investment property to build long-term wealth. But between the moment you decide to invest and the moment a tenant moves in, there are a dozen steps where the wrong move costs you real money.
This guide walks through the entire buying process, from setting your investment criteria through to settlement and tenanting. Each step includes what to do, what it costs, and the mistakes that catch first-time investors off guard.
Step 1: Set Your Investment Criteria
Before you look at a single listing, get clear on what you're buying and why. Your criteria should cover:
- Budget. What can you actually afford, not just what a bank will lend you? Factor in the deposit, stamp duty, legal fees, and a cash buffer for the first few months of ownership.
- Strategy. Are you chasing rental yield, capital growth, or both? A high-yield regional property and a negatively geared inner-city apartment are fundamentally different strategies with different risk profiles.
- Property type. House, unit, townhouse, or vacant land. Each has different maintenance obligations, strata implications, and depreciation profiles.
- Location parameters. Proximity to transport, schools, shops, and employment centres. According to Moneysmart, you should look for areas with high growth, higher rental yield, and low vacancy rates, and find out about proposed planning changes in the suburb that may affect future property prices.
Writing your criteria down before you start browsing prevents emotional purchases. It also makes it easier to evaluate deals quickly when they come up.
If you're weighing up whether to buy your own home first or invest while renting, our rentvesting guide breaks down the numbers on that decision.
Step 2: Understand Your Upfront Costs
The purchase price is the obvious number. It is not the only number. Before you approach a lender, build a realistic picture of what the total acquisition will cost.
Stamp Duty (Transfer Duty)
This is typically the largest upfront cost after your deposit. Every state and territory charges it, and the rates differ.
In NSW, Revenue NSW states that you must pay transfer duty based on the property's sale price or its current market value, whichever is higher, within three months of signing the contract (or before settlement if earlier). On a $700,000 property in NSW, transfer duty lands at approximately $26,069.
In Victoria, the State Revenue Office confirms land transfer duty applies to all property types, with a premium rate for properties above certain thresholds.
Investment properties do not qualify for first home buyer exemptions or concessions. Budget for the full rate.
Other Upfront Costs
According to Moneysmart, costs to buy a property include stamp duty, conveyancing fees, legal costs, search fees, and pest and building reports.
The ATO notes that borrowing expenses can be claimed as a deduction spread over 5 years (or the loan term, whichever is shorter), including loan establishment costs, title search fees, and lenders mortgage insurance. However, stamp duty and legal fees for the purchase are not immediately deductible — they're added to the cost base of the property for CGT purposes when you sell.
A rough rule: budget 5–7% of the purchase price for total acquisition costs on top of your deposit.
Step 3: Get Finance Pre-Approval
Pre-approval tells you exactly what a lender will offer you, and signals to sellers and agents that you're a serious buyer.
How Investment Lending Differs
Investment loan interest rates are typically higher than owner-occupier rates. You will also need a larger deposit — most lenders require a minimum 10%, and you will pay lenders mortgage insurance (LMI) if your deposit is below 20%.
Moneysmart warns that many people buy investment property with interest-only loans, but the interest-only period will end after a certain time, meaning your repayments will increase to cover both principal and interest. Factor that into your long-term serviceability modelling.
What Lenders Assess
Lenders look at your income, existing debts, living expenses, and the expected rental income from the property. They will stress-test your repayments at a rate above the actual loan rate to ensure you can still service the debt if rates rise.
Get pre-approval before you start inspecting properties. It saves you from falling in love with something you cannot afford.
Step 4: Research Locations and Properties
With your criteria set and budget locked in, it is time to find the right property in the right location.
Location Research
Your location research should include:
- Rental demand. Check vacancy rates through local property managers or data providers. Low vacancy rates (under 2%) indicate strong tenant demand.
- Comparable rents. What are similar properties renting for? This feeds directly into your rental yield calculation.
- Infrastructure plans. New transport links, hospitals, or university expansions can drive both capital growth and rental demand.
- Council zoning. Check if the area is earmarked for higher-density development, which could mean more competing rental stock in the future.
Property Inspections
NSW Fair Trading recommends arranging property and pest inspections and requesting any existing reports from the seller. For strata properties, get a strata search report before you buy.
Never skip the building and pest inspection. A $500 report can save you from a $50,000 structural problem.
Step 5: Make an Offer or Bid at Auction
There are two main ways to buy property in Australia: private treaty (negotiation) and auction. Understanding how each works protects you from overpaying.
Private Treaty
You submit a written offer to the seller through the agent. The seller can accept, reject, or counter. You can include conditions such as “subject to finance” or “subject to building and pest inspection”, which give you an exit if something goes wrong.
Auction
At auction, the property sells to the highest bidder once it passes the reserve price. There is no cooling-off period at auction in most states — if you are the winning bidder, you are legally committed and must pay the deposit (typically 10%) on the spot.
Complete all your due diligence before bidding: building and pest inspection, contract review, and finance approval. You will not get a second chance.
Step 6: Exchange Contracts
Once your offer is accepted (or you win at auction), contracts are exchanged. This is where the deal becomes legally binding.
What Happens at Exchange
- You pay the deposit (usually 10%, though 5% can sometimes be negotiated in a private treaty sale).
- Both parties sign the contract of sale.
- The cooling-off period begins (if applicable). In NSW, private treaty sales have a 5 business day cooling-off period. At auction, there is none.
The Role of Your Conveyancer or Solicitor
A conveyancer or property solicitor handles the legal transfer, reviews the contract, conducts title searches, and ensures there are no encumbrances affecting your ownership. NSW Fair Trading also notes that the conveyancing process at settlement identifies any unpaid expenses (rates, utility fees) and pro-rates them between buyer and seller from the settlement date.
Engage a conveyancer before you make an offer. Reviewing a contract after you have already committed puts you in a weaker position.
Step 7: Settlement
Settlement is the final step in the legal transfer of ownership. It typically occurs 30 to 90 days after exchange, depending on what the contract specifies.
What Happens at Settlement
- Your lender transfers the balance of the purchase price to the seller's solicitor or conveyancer.
- The title is transferred into your name (or your entity's name, if purchasing through a trust or company).
- You receive the keys.
Revenue NSW notes that settlement cannot take place if transfer duty has not been paid. Make sure your conveyancer has lodged and paid stamp duty before the settlement date.
Immediately After Settlement
The ATO recommends keeping records from the time you buy the property, through to 5 years after you sell it. Start your record-keeping system on day one.
Also note: if you do any work to repair damage that existed when you purchased the property, these “initial repairs” are capital expenses, not immediate deductions. They are added to the cost base for CGT purposes.
Step 8: Get the Property Ready to Rent
Landlord Insurance
This is separate from building insurance. Landlord insurance covers tenant damage, loss of rental income, and legal liability. According to Moneysmart, ongoing investment property costs include council and water rates, building insurance, landlord insurance, body corporate fees, land tax, property management fees, and repairs and maintenance.
Property Manager or Self-Manage
A property manager typically charges 5–10% of the weekly rent, plus letting fees for finding new tenants. They handle advertising, tenant screening, rent collection, inspections, and maintenance coordination.
Self-managing saves the fee but costs your time and requires you to stay across tenancy legislation in your state. If you're weighing up the options, our buyers agent alternative guide covers how to get professional support without traditional fee structures.
Setting the Rent
Price the property based on comparable rentals in the area, not on what you need to cover the mortgage. Overpricing leads to extended vacancy, and even a few weeks empty can wipe out the difference between a higher and lower asking rent across a full year.
Use our rental yield guide to work out gross and net yield once you have the rent figure locked in.
Step 9: Understand Your Ongoing Tax Obligations
The ATO states that if you own a residential rental property, you need to keep records, declare income, and claim expenses correctly.
Income You Must Declare
You must declare all rental-related income in your tax return, including rental income from tenants (including cash payments), bond money you retain, and insurance payouts.
Deductions You Can Claim
We cover this in detail in our investment property tax deductions guide. At a high level, you can claim loan interest, property management fees, council rates, insurance, and repairs — either immediately or over time depending on the category.
Be aware that the 2026 Federal Budget announced changes to negative gearing and capital gains tax, subject to final legislation. Make sure you take these changes into account when modelling your investment returns.
Records
The ATO says the key to making tax time easier is keeping good records and creating a record system that works for you. Records can be in paper or digital format — keep a backup of all digital records.
Common Mistakes to Avoid
Underestimating holding costs. Moneysmart warns that rental income may not cover your mortgage payments and other expenses. A rise in interest rates means higher repayments and lower disposable income. Always stress-test your numbers.
Skipping due diligence on strata properties. NSW Fair Trading recommends getting a strata search report before you buy. Special levies for building defects can run into tens of thousands of dollars.
Not diversifying. Moneysmart advises investing in more than just property so your money is not all in one market. Putting everything into one asset class increases your risk.
Treating initial repairs as deductions. The ATO is clear: repairs to fix damage that existed when you bought the property are capital expenses, not immediate deductions. Getting this wrong attracts ATO attention.
