When to Buy an Investment Property
Timing matters when you're buying an investment property, but it's less about picking the market bottom and more about matching your borrowing capacity to a genuine income opportunity.
The legislation changes that came into force in June brought new tax treatment for properties purchased after mid-May. If you're looking at an established property now, losses from that investment can only be offset against other residential property income from the 2027-28 income year onwards. That shifts the focus away from short-term tax relief and towards properties that can hold their own on rental yield.
Consider someone earning $95,000 who's saved a 15% deposit and wants to buy a unit close to public transport. Under the current debt-to-income lending limit introduced in February, lenders can only allocate 20% of their new investor loans to borrowers with a total debt ratio of six times income or higher. For this buyer, six times income is $570,000. If they already hold an owner-occupied loan of $420,000, their total borrowing sits at the threshold before they add any investment loan amount. The timing question becomes whether they can service a new loan at current variable rates plus the 3% assessment buffer, or whether waiting another 12 months to reduce their owner-occupied balance makes the numbers work.
How Rental Income Affects Your Borrowing Power
Lenders assess investment loan serviceability using rental income, but not at face value.
Most lenders shade rental income by 20% to account for vacancy periods, maintenance and management costs. If a property generates $550 per week in rent, the lender applies $440 per week to your serviceability calculation. That $110 weekly reduction across a year equals $5,720 in income the lender won't count. At the same time, your loan repayments are assessed at the product rate plus 3%, so even if you're borrowing at a variable rate around 6.3%, the lender tests your capacity to repay at roughly 9.3%.
In our experience, buyers who time their purchase to align with strong rental demand in their chosen area rather than chasing capital growth in softer yield suburbs end up with more borrowing headroom. A property returning 5% gross yield in an area with consistent tenancy demand will service itself more reliably than a property returning 3.5% in a suburb where rents have stalled.

Interest Rate Structure and Loan Features
You can choose a variable rate, a fixed rate, or split your loan across both.
Variable rates on investment loans typically sit higher than owner-occupied rates, and lenders apply a risk margin based on your loan to value ratio and whether you're making principal and interest or interest-only repayments. A fixed rate locks your repayments for a set term, usually between one and five years, but comes with restrictions on extra repayments and can trigger break costs if you exit early. Interest-only periods let you reduce your monthly outgoings in the early years, which can help with cash flow if you're holding multiple properties or managing renovation costs. Keep in mind that interest-only loans classified as long-term and above 80% LVR attract a higher capital risk weighting under the prudential standards, which flows through to pricing.
As an example, someone purchasing a townhouse in a regional centre might split their loan 50-50 between a three-year fixed rate and a variable rate with an offset account. The fixed portion provides certainty during the early tenancy phase, and the variable portion with offset gives them flexibility to park surplus cash and reduce interest without losing access to funds. That structure works when you expect rental income to build gradually and want the option to make lump sum reductions without penalty.
Tax Treatment for Properties Purchased After May
Properties acquired after 7:30pm on 12 May can only offset losses against income from other residential properties from the 2027-28 financial year onwards.
If you purchase an established investment property now and it runs at a loss due to loan interest exceeding rental income, you cannot deduct that loss against your salary. You can carry the loss forward and use it to offset future residential property income, including capital gains when you sell. New builds are exempt. If you're buying a property constructed on previously vacant land, or a development that increases the dwelling count on a parcel, the old negative gearing rules still apply and you can offset losses against all income.
This changes the timing calculation. A property that delivers modest positive cash flow or breaks even becomes more valuable than a high-growth property with weak yield, particularly if you're not planning to build a portfolio of multiple residential investments where losses can be pooled. If you're holding property purchased before mid-May, or you're under contract before that date and settle later, the old rules continue to apply for as long as you hold that property.
Loan to Value Ratio and Deposit Requirements
Most lenders will lend up to 90% of the property value for an investment loan, but anything above 80% LVR requires lenders mortgage insurance.
LMI premiums are calculated on a sliding scale and increase sharply as your LVR rises. The premium is a one-off cost, usually capitalised into the loan, and varies depending on the insurer, the loan amount and your LVR. On top of the premium, some states charge stamp duty on the insurance itself. A 15% deposit avoids LMI entirely and gives you access to sharper interest rate pricing, particularly if you're borrowing a larger amount.
If you already own property, you might be able to use equity from that property as part of your deposit rather than drawing down cash savings. Lenders will value your existing property, apply an 80% LVR to that valuation, subtract your current loan balance, and treat the difference as available equity. You can then use that equity as security for the new investment loan, subject to your overall serviceability. Timing becomes relevant if your existing property has increased in value but you haven't had it revalued recently. Requesting a valuation update before you apply can increase your available equity and reduce or eliminate the need for LMI on the new purchase.
Capital Gains Tax Changes from July 2027
From 1 July 2027, capital gains on residential investment properties will be taxed under a new method that indexes your cost base to inflation and applies a 30% minimum tax rate to real gains accruing after that date.
For properties purchased now and sold after mid-2027, gains will be split. The portion of the gain that accrued before 1 July 2027 is taxed under the current 50% discount method. The portion accruing after that date is taxed under the indexed method with the 30% minimum rate. You can choose between a market valuation as at 1 July 2027 or an ATO apportionment formula to divide the gain. If you're buying an eligible new build, you'll have the option to use either the old discount method or the new indexed method when you sell, whichever delivers the lower tax.
The change affects timing in two ways. If you're buying an established property purely for capital growth and plan to sell within a few years, the new tax treatment reduces your after-tax return compared to the old rules. If you're buying a new build or holding long-term in an inflationary environment, indexation may deliver a lower taxable gain than the flat discount, particularly if inflation remains elevated. The choice matters more for investors in higher tax brackets who would otherwise lose most of the benefit of the 50% discount.
Foreign Investment Restrictions and Established Dwellings
Foreign investors are currently banned from purchasing established dwellings until 30 June 2029, with limited exceptions.
Temporary residents can still apply for approval to purchase new dwellings or vacant land. Permanent residents and New Zealand citizens are exempt. The restriction was extended in the most recent federal budget and is intended to redirect foreign capital towards new housing supply. For Australian residents and citizens, the restriction has indirect effects on timing. Established property in high-demand areas that previously attracted foreign buyer interest may see slower price growth in the short term, which can create entry opportunities for local investors if rental fundamentals remain solid. On the other hand, new builds and vacant land may see stronger competition as foreign capital concentrates in the segments still available.
Development conditions on vacant land require foreign purchasers to complete construction within four years and prohibit resale until construction is finished. Compliance is being actively enforced, and the ATO received additional funding in the last two budgets to target land banking. If you're considering a purchase in a precinct with high foreign ownership, it's worth checking settlement and construction timelines to understand whether supply is likely to increase in the near term.
Borrowing Capacity and Debt-to-Income Limits
The debt-to-income limit introduced in February caps high-DTI lending at 20% of each lender's new investor loan book each quarter.
If your total debt sits at six times your gross income or above, you're competing for a limited portion of each lender's quarterly allocation. That doesn't mean you can't borrow, but it does mean your application will be assessed more closely and you may need to approach multiple lenders to find capacity. The limit applies separately to investor and owner-occupied lending, so your investor loan is measured against the 20% investor cap, not the owner-occupied cap.
Timing comes into play if you're at or near the six-times threshold. Paying down existing debt, increasing your income or waiting for a rate cut that improves your serviceability can shift you below the threshold and give you access to the other 80% of the lending pool. Alternatively, if you're planning to buy multiple properties over time, sequencing your purchases so that earlier acquisitions have time to build equity and improve your overall position can keep you below the DTI limit on subsequent purchases. Working with a broker who has access to investment loan options from banks and lenders across Australia increases your chances of finding a lender with available capacity in their quarterly allocation.

Frequently Asked Questions
Can I still negatively gear an investment property purchased now?
If you purchase an established property after 12 May, losses can only be offset against other residential property income from the 2027-28 financial year onwards. New builds are exempt and continue to allow full negative gearing against all income.
How does the debt-to-income limit affect investment loan timing?
If your total debt is six times your income or more, you're limited to 20% of each lender's quarterly investor loan allocation. Timing your purchase after reducing existing debt or increasing income can move you below the threshold and improve access to lending.
What deposit do I need for an investment property?
Most lenders will lend up to 90% LVR, but anything above 80% requires lenders mortgage insurance. A 15% deposit avoids LMI and typically gives you access to lower interest rates.
How do lenders assess rental income for serviceability?
Lenders typically shade rental income by 20% to account for vacancies and costs. They also assess your loan serviceability at the product rate plus a 3% buffer, so rental yield and vacancy rates in your chosen area directly affect borrowing capacity.
How will capital gains tax change from July 2027?
From 1 July 2027, gains on investment properties will be taxed using cost base indexation and a 30% minimum rate on real gains accruing after that date. Gains accruing before that date continue to use the 50% discount method.
