When Not to Buy an Investment Property

Buying when you cannot afford vacancy

Your investment property should be able to withstand at least eight weeks without rental income before you commit to settlement. If eight weeks of holding costs without rent would force you to sell or default, the timing is wrong.

Consider someone who purchased a unit in a Brisbane suburb with a loan requiring $2,400 per month in interest-only repayments. Rental income covered $2,200 of that amount, leaving a $200 monthly shortfall. When the tenant gave notice and the property sat vacant for ten weeks during a slower leasing period, the investor faced $4,800 in holding costs with no income. They had no offset balance and no separate reserve, so the shortfall went onto a credit card. The property eventually re-leased, but the investor was still repaying that gap six months later.

Vacancy is not an exception in Brisbane. It is a recurring feature of owning residential property. Tenants leave, properties need maintenance between leases, and some locations experience seasonal demand. If your deposit, income buffer or offset account cannot cover two to three months of full holding costs, the property becomes a financial risk rather than a wealth-building tool. Lenders assess serviceability on the loan repayment, not the net position after rent, but serviceability at application and cashflow during ownership are different things.

When legislation works against your tax position

From the 2027-28 income year, losses on established residential properties purchased after 12 May 2026 can only be offset against other residential property income, not your salary. That change affects the after-tax cost of holding a negatively geared property and shifts the affordability equation for many Brisbane renters considering their first purchase.

Under the previous rules, an investor earning $95,000 per year who made a $6,000 annual loss on an investment property could reduce their taxable income to $89,000 and receive part of that loss back as a tax refund. Under the new rules, that $6,000 loss is quarantined and carried forward until the property is sold or generates a gain. The investor still wears the full $6,000 out of pocket each year with no immediate tax relief.

Negative gearing still works if you buy new builds or properties already owned before the legislation took effect, and it still works for those with multiple properties generating overall income. But if you are purchasing your first established investment property now and expect to rely on tax refunds to cover the shortfall, that support is gone. Timing a purchase when your income, rent and interest rate align to produce a neutral or positive position makes more sense than borrowing into a loss you cannot claim.

Buying before your borrowing capacity is clear

APRA introduced a debt-to-income lending limit from February 2026, capping the portion of new investment loans that banks can write to borrowers with total debt exceeding six times their income. The limit does not prevent you from borrowing at a high DTI, but it does mean fewer lenders will approve your application, and those who do may price the loan differently or require a larger deposit.

If your borrowing capacity sits right at the edge of what one or two lenders will approve, a small change in your income, expenses or interest rates can push the application into decline. We see this regularly with Brisbane renters who want to purchase interstate or in regional Queensland while continuing to rent locally. Their rental payment is treated as an ongoing expense, the investment loan is assessed at the actual rate plus a 3 percentage point buffer, and rental income from the investment property is shaded by at least 20 per cent. Once those calculations are complete, someone earning $100,000 who can theoretically service a $600,000 loan may only be approved for $480,000, and only by a subset of lenders.

Knowing your real borrowing capacity before you start looking at properties prevents you from signing a contract you cannot settle. Run the scenario with your broker first, adjust your deposit or income position if needed, and then make an offer. Buying a property and hoping the finance works out is not timing, it is gambling.

When rental income is already priced into your next purchase

Some buyers assume they can use the rental income from their first investment property to help service a second loan immediately after settlement. Lenders do not assess it that way. Most will not include rental income in your serviceability at all until you have received at least three months of rent and can provide signed leases and bank statements showing the income hitting your account.

That delay matters if you are planning to build a portfolio quickly. If you purchase your first property in July and settle in September, you may not be able to use that rental income to support a second application until January at the earliest. If the property sits vacant for a period after settlement, the timeline extends further. Timing a second purchase before your rental income is recognised means you are assessed on your salary alone, and your borrowing capacity for the second loan will be lower than you expect.

The same issue applies when buyers want to release equity from an existing property to fund a deposit on the next one. You need a valuation, and that valuation needs to support the new loan-to-value ratio you are targeting. If you refinance or top up your loan before the valuation reflects recent price growth, you may not access enough equity to proceed. Sequencing matters, and trying to compress the timeline usually just creates delays once the application is submitted.

Buying in a market you have not researched

Brisbane investors are often drawn to interstate markets offering higher rental yields or lower entry prices, but buying in a location you do not understand creates problems that do not show up until after settlement. Vacancy rates, tenant demand, body corporate costs for units, insurance premiums and property management fees all vary by location, and those variables directly affect whether the property performs as expected.

A buyer purchasing a unit in a regional area without checking the local vacancy rate or typical lease duration may find the property sits empty for months or attracts only short-term tenants. Regional markets can also have different strata cost structures, particularly for buildings with pools, lifts or older common property needing repair. If those costs were not factored into the holding cost calculation at purchase, the cashflow position can turn negative quickly.

We worked with someone who purchased a unit in a coastal town based on the advertised rental yield, without confirming how that yield was calculated. The advertised figure assumed year-round occupancy at peak holiday rates, but the property was in an area with strong short-term rental demand and weak long-term lease demand. The investor wanted a permanent tenant to avoid the management intensity of short stays, but the property sat vacant for four months before they adjusted their approach. The yield they actually achieved was nearly half what they expected. Timing the purchase for after the research, not during it, would have led to a different property choice or a different location altogether.

When your deposit includes funds you cannot prove

Lenders require all deposit funds to be verified, and they distinguish between genuine savings held in your account for at least three months and funds that appear suddenly from a gift, sale or other source. If part of your deposit comes from a family gift or the sale of assets like shares or a car, you will need a signed declaration from the person providing the funds, and in some cases the lender will exclude those funds when calculating your borrowing capacity or require a higher LVR.

If you are planning to buy in the next few months but your deposit is currently split between your account, a term deposit maturing soon, and a cash gift from a parent that has not yet been transferred, the timing is uncertain until all of those funds are in your account and documented. Contracts in Queensland routinely require a 10 per cent deposit on exchange, and if you cannot prove you hold those funds in a form the lender will accept, your finance approval may be delayed or conditioned in ways that affect settlement.

Rentvesting with a small deposit is workable if the deposit you have is genuinely yours and has been saved over time, but if your deposit position is not yet clear, waiting until it is will make the finance process faster and the approval more certain.

Locking in a rate structure you do not need yet

Some buyers fix part or all of their investment loan at application because they want certainty, but if your income or circumstances are likely to change in the next two years, a fixed rate can cost you more than it saves. Fixed loans generally do not allow extra repayments beyond a small annual threshold, and they do not allow you to redraw or access offset during the fixed period. If you exit the fixed rate early to refinance, sell or restructure, you will likely pay break costs.

An investor who fixed a $500,000 loan for three years and then wanted to sell the property eighteen months later faced $9,000 in break costs because the market rate at exit was lower than the fixed rate they had locked in. That cost reduced the net sale proceeds and wiped out part of the capital gain. The fixed rate was not wrong in itself, but the timing did not match the investor's actual plans. If you are not certain you will hold the loan and the property for the full fixed term, a variable rate or a split loan structure gives you more flexibility without the penalty.

Moving forward when the timing supports your position

Property investment timing is not about predicting markets or waiting for prices to fall. It is about making sure your income, deposit, tax position and borrowing capacity align with the property and loan structure you are considering, and that you have enough buffer to manage the holding costs when rental income is delayed or absent.
