How to Choose an Investment Property in a Buyer's Market: A Buyer's-Agent-Style Checklist (2026)

Published 24 October 2026 · Prepared by the Property Investment Professionals research desk · Market data, rates and tax law checked 23 October 2026

Capital-city vendors accepted a median discount of 4.4% in September, the largest in five years, and capital-city homes took a median 39 days to sell against 23 a year earlier (Cotality Monthly Housing Chart Pack, 15 October 2026). Cotality's final auction clearance rate for the combined capitals was 44.1% in the week ending 11 October, against 68.2% in the same week of 2025 (Cotality). Domain's September-quarter House Price Report, released 22 October, found house prices fell in every capital for the first time in 15 years, with conditions continuing "to shift in buyers' favour".

If you are working out how to choose an investment property in this market, negotiating has become the easier job and judging the asset the harder one, because falling markets bring weak properties to sale alongside sound ones.

This guide is our editorial checklist, modelled on the due-diligence steps buyers' agents commonly describe: shortlist on rental demand and supply, inspect, then finish due diligence before the contract goes unconditional. Each of the twelve tests has a public data source. We run the numbers at an illustrative modelling rate of 6.75% under the enacted negative gearing rules; substitute the rate your lender quotes. Whether to buy at all is covered in our should I buy in a buyer's market guide, and which city in our location guide; this article starts once you are looking at listings.

In one sentence: choose the property on tests a discount cannot change (rental demand, supply, land, holding cost and tax treatment), then use your bargaining power on price and conditions.

What has changed now that buyers have the upper hand?

Where the shift is sharpest

Cotality's new listings were down 7.9% on the same four weeks of 2025, so the extra stock comes from slower sales. The chart pack shows Brisbane's median selling time going from 17 to 38 days over the year to September and Perth's from 11 to 26, with total listings up 60.4% and 64.7% respectively. Domain recorded the steepest quarterly falls on record for Perth houses (−7.4%) and Brisbane houses (−5.4%) in the September quarter.

In the last downturn, CoreLogic (now Cotality) recorded a 7.5% national fall from the April 2022 peak to a January 2023 trough, then a new record high in November 2023, about ten months later. This time rates are rising from a higher base and the tax rules change on 1 July 2027, so treat a 2023-style recovery as one possible scenario and leave it out of your numbers.

What the shift gives you

At a 39-day capital-city median you can inspect twice and confirm the loan before committing, compare several candidates in one price band, and, as Domain reports "a growing number of auction campaigns converting to private treaty sales", ask for finance, building and valuation conditions.

What it does not change

The cash rate is 4.60% after the Reserve Bank's fourth rise of 2026 on 29 September. Deputy Governor Andrew Hauser said on 21 October that "the inflation outlook looks materially worse than we projected in the August report" (RBA transcript). As at 6 October, Westpac and ANZ expected a fifth rise to 4.85% at the Tuesday 3 November meeting while CBA and NAB expected a hold (Aussie). After Hauser's remarks, market pricing put the chance of a rise at that meeting at 51% (Bloomberg data reported by the ABC, 21 October); the ASX RBA Rate Tracker shows the current figure. A 0.25-point rise passed on in full would take our 6.75% modelling rate to 7.00%, the stress rate in this guide.

How do you choose an investment property? A buyer's-agent-style review

Gate 1: rental demand

Test: the postcode vacancy rate from SQM Research, free monthly for every postcode, and its direction over six to twelve months. SQM counts rentals advertised for three weeks or more as a share of the estimated established rental stock, across all dwelling types in the postcode.

Threshold (our rule of thumb): at or below 2.0–2.5%, and flat or falling for the last three months. SQM's national rate was 1.4% in September; Sydney was 1.8% (1.3% in September 2025) and Melbourne 1.9%, while Brisbane, Perth, Adelaide, Darwin and Hobart were below 1%.

A postcode at 1.7% that was 1.3% a year ago is moving the wrong way, and rising vacancy often shows up before falling rents. Allow for seasonality: inner-city and student postcodes often spike in December and January. Where the rental stock is small, a few listings move the rate (one listing in postcode 5112 is about 0.03 points), so read the listing count beside the percentage.

Gate 2: rent trend for your property type

Test: SQM's weekly asking rents by postcode, split into houses and units, over the quarter and the year.

House and unit rents are diverging. SQM recorded unit asking rents falling over the 30 days to 12 October in seven of the eight capitals while national house rents rose, and Louis Christopher, SQM's managing director, said "the more telling signal is in units". A falling quarter after a strong year is a reason to use a lower rent in your numbers rather than an automatic fail.

Supply pipeline: a qualitative flag

Test: what is approved and under way within one to two kilometres, set against the existing rental stock.

The ABS recorded 16,953 dwelling approvals in August (seasonally adjusted), down 6.1% on July, with private-sector approvals for apartments and other non-house dwellings down 21.2% over the month (ABS Building Approvals). A national shortfall can sit beside a local glut, and the local number sets your rent.

There is no published standard for how much supply is too much, so we treat this as a flag for judgement, not a pass-or-fail gate. Our guide: divide the last 12 months of ABS dwelling approvals for the SA2 by the rented dwellings in the 2021 Census tenure data for that area, and compare the ratio with neighbouring SA2s. An area well above its neighbours, or with one large precinct approved nearby, needs a closer look. Approvals overstate future rentals (some will be owner-occupied, some never built) and the Census count is five years old, so treat the ratio as a reason to look harder. Council registers, PlanningAlerts and state master-planned areas show individual projects.

Land-to-asset ratio

Test: the site value from your state valuer-general (or the council rates notice) divided by the price.

Over long periods land usually drives value growth while the building depreciates. Our rule of thumb: for houses, a land share of 40–50% or more; for units, accept a lower share only in a small, older block without much new competition. Site values lag the market, and new house-and-land packages show a lower share because the price includes building and developer margins.

Owner-occupier share and buyer depth

Test: tenure in the suburb from ABS Census QuickStats.

Owner-occupiers are usually the deeper resale pool. In NAB's September-quarter survey, owner-occupiers (excluding first-home buyers) made up 45.6% of established-home buyers, first-home buyers 34.4% and local investors 14.7%. Domain said investors were "pulling back in response to tax policy changes, higher borrowing costs and a softer price outlook". While that lasts, a type that depends on investor buyers has a thinner resale pool.

Days on market, discount and stock

Tests: this listing's days on market against the local median; its first asking price against comparable sales; and suburb listings against a year ago.

Cotality's September medians in the table above are only the backdrop; build local evidence from sold listings nearby. As a rule of thumb (ours), a listing at twice the local median with one price cut usually signals a motivated vendor, while three times the median with several cuts often points to a defect, a strata problem or a price the market has already rejected, so find out which. Our negotiation guide covers turning this evidence into an offer.

Building, strata and hazard checks

Tests: a pre-purchase building and pest inspection; for strata title, a records search (minutes, capital works fund, special levies, defect claims); flood, bushfire and heritage overlays from the state planning portal; and an insurance quote before exchange.

A special levy for cladding or waterproofing can exceed the negotiated saving several times over. In a buyer's market you can usually make the contract conditional on these reports.

Exit liquidity

Test: how many comparable properties sell, and how fast.

Cotality's final clearance rates for the week ending 11 October ranged from 49.8% in Melbourne to 21.8% in Brisbane. Given NAB's buyer shares, our expectation is that types selling in volume to owner-occupiers (established houses, family townhouses) regain liquidity sooner than those relying on investor demand (studios, serviced or student units).

What do the criteria look like on real suburbs right now?

Source: SQM Research postcode vacancy (September 2026, all dwellings) and weekly asking rents (week ending 20 October 2026, all houses or all units in the postcode), accessed 23 October 2026; PropTrack September-quarter 2026 suburb median values for the type shown, published by realestate.com.au on 11 October 2026. Indicative yields are our calculation (rent × 52 ÷ value) and mix a postcode rent with a suburb value, so treat them as approximate; unit yields are not calculated because postcode unit rents mix newer apartments with older stock. Postcodes cover more than one suburb (4301 includes Collingwood Park and Redbank; 5112 several Elizabeth localities; 3029 Truganina and Hoppers Crossing; 2150 Harris Park; 2017 Waterloo).

Redbank Plains. SQM's vacancy rate for postcode 4301 was below 1% in ten of the past twelve months, while PropTrack's Redbank Plains house median fell 10% over the quarter. The indicative gross yield of about 4.2% divides SQM's postcode house rent by PropTrack's suburb house value, so it is approximate. Supply is the open question. The Ripley Valley Priority Development Area, about five kilometres south-east of the Ipswich CBD, is planned for about 48,750 dwellings, according to Economic Development Queensland. New lots there will compete with resales for years, which favours established streets with features new estates lack (larger blocks, rail access, existing services) over near-new houses priced close to new.

Elizabeth. Vacancy passes, and the indicative gross yield is about 4.1% (postcode house asking rent ÷ suburb house median), but postcode house asking rents eased 5.8% over the quarter, so use the rent achieved on recent leases.

Parramatta. SQM vacancy of 1.74% is within the gate, but it climbed from 0.99% in April before holding steady in September. Under our trend rule it is a "keep watching" case; three months without a rise would see it pass again.

Tarneit. SQM vacancy in postcode 3029 is down from about 5% a year ago but up from 3.25% in August, with house asking rents flat. It fails until vacancy is back under the gate.

Zetland. SQM counted 569 advertised rentals in postcode 2017. A discount here buys into a rental market that is getting harder, in a precinct where new apartments keep arriving.

Does the property pay its way at today's interest rates?

Interest cover and cash flow are different tests

Interest cover is gross rent divided by the interest bill. Cash flow is what is left after every holding cost and the repayment, so 100% interest cover can still cost you money. Cotality's national gross yield is 3.85%, the highest since August 2019, yet Cotality notes that "opportunities for neutral to positive cash flow remain low". At 80% LVR and the 6.75% modelling rate, rent covers the interest alone only at a gross yield of about 5.4%.

A worked example

The RBA's Table F6 put the average rate on new investor variable-rate loans at 6.40% in August, before the big four passed on the September rise in full from 9 October. We use 6.75% as an illustrative modelling rate and 7.00% as the stress rate. Neither is a market average or a lender quote: substitute the rate your lender quotes.

Illustrative property: an established house listed at $730,000, bought for $698,000 (4.4% below asking), renting at $560 a week. Loan of $558,400 (80% LVR), interest-only. Investor earning $160,000 (37% marginal rate plus 2% Medicare levy). Contract signed after 12 May 2026, so the property is a post-cut-off established purchase.

Source: our illustrative calculation. Excludes stamp duty, land tax, depreciation, rent growth and capital growth, which vary by state and property. The 6.75% and 7.00% rates are modelling assumptions, not lender quotes.

Switching to principal and interest lifts the pre-tax outlay to about $26,500 a year. About $5,950 of that repays debt in year one: it reduces the loan but is not tax-deductible, because only the interest is. Our analysis: on the interest-only numbers the house needs to grow by about 3.0% a year ($20,800 ÷ $698,000) to cover the pre-tax holding cost, or about 1.8% on the 2026-27 after-tax cost, before buying and selling costs.

What a 4.4% discount is worth

Paying the full $730,000 would mean a $584,000 loan and a pre-tax shortfall of about $22,630. The discount is worth about $1,860 a year in cash flow, plus $6,400 less deposit and lower stamp duty. A little over three weeks of extra vacancy a year ($1,860 ÷ $560) would cancel the cash-flow gain.

The break-even yield

Few capital-city houses reach these yields; Cotality's capital-city dwelling yields ran from 3.4% in Sydney to 6.5% in Darwin in September. Neutral cash flow at today's rates comes from a lower LVR, a higher-yield market with its own risks, or both. Our positive cash flow guide covers the options and the cash-flow calculator runs your numbers.

Deposit, LVR, buffer and lender differences

Borrowing capacity and deposit capacity are separate limits. APRA expects banks to assess new loans at a rate at least 3 percentage points above the loan product rate, about 9.75% on the modelling rate here. Since 1 February 2026, APRA has limited each bank's new lending at a debt-to-income ratio of six or more to 20% of new lending, separately for owner-occupier and investor loans; that is a portfolio speed limit, not a borrower-level cap. Above 80% LVR most lenders charge lenders mortgage insurance, and lenders differ in how much rent they count.

A bank valuation below the contract price leaves you to fund the gap, so a finance condition tied to a satisfactory valuation is worth more in a falling market. Check capacity early with the borrowing capacity calculator and a broker's written assessment.

New build or established after the negative gearing reform?

What the Act says

The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on 26 June 2026 (Act on legislation.gov.au). Two dates in it do different jobs.

12 May 2026 decides negative gearing. Schedule 2 inserts section 26-155 into the Income Tax Assessment Act 1997. From 1 July 2027, net rental losses on established residential dwellings whose ownership interest was last acquired after 7:30pm (ACT legal time) on 12 May 2026 are not deductible against salary or other income. The quarantined amount offsets residential rental income in the same year, is applied against residential capital gains, and any remainder carries forward to later years. Earlier purchases and new residential dwellings are outside the rule, and for a property bought under contract the interest is acquired when the contract is signed, so a contract signed now is on the post-cut-off side.

1 July 2027 decides CGT. For assets held by Australian-resident individuals through 30 June 2027 (with separate provisions for trusts), the Act treats the asset as sold at market value just before 1 July 2027 and reacquired at that value (sections 112-155 and 112-160). This deemed disposal is not a taxable sale. The gain or loss to that date is deferred until the property is sold, and the deferred gain keeps the 50% discount if it qualifies. Growth after 1 July 2027 is taxed on a CPI-indexed cost base, and a 30% minimum tax (Division 119) applies to certain capital gains of resident individuals under its own conditions. The deemed disposal applies to qualifying assets whatever their purchase date; the 12 May 2026 cut-off applies only to negative gearing.

Eligible new residential dwellings are treated differently on CGT. They are excluded from the deemed disposal, and under section 115-102 a gain on a new residential dwelling keeps the 50% discount; the investor can instead choose indexation, in which case the 30% minimum tax can apply. Our negative gearing guide and 1 July 2027 CGT guide set out the mechanics.

The Tax Reform No. 3 Bill

On 14 October 2026 the Treasurer introduced the Treasury Laws Amendment (Tax Reform No. 3) Bill 2026. In the second reading speech, Dr Chalmers said "Schedule 5 legislates the definition of a new residential dwelling"; the Bill also exempts affordable and public housing from the negative gearing limits. It is a Bill and can be amended. Treasury's August consultation draft proposed treating a dwelling as new if acquired within 24 months of its occupancy certificate, so treat edge cases (off-the-plan resales, substantial renovations) with care until the law is settled.

How the tax rules change the criteria

For established property bought now, the after-tax cost in our example rises by about two-thirds from 1 July 2027, from about $12,700 to $20,800 a year. The loss carries forward, but the cash still leaves your account each year, so the holding-cost test and the buffer are pre-tax.

For new dwellings, the deduction against salary continues and the investor keeps the choice between the 50% CGT discount and indexation. Depreciation deductions are also usually larger, though they are claimed gradually over several years. Division 40 deductions for plant and equipment depend on the asset and on whether it was previously used or installed ready for use (the ATO's rules limit claims on second-hand assets in residential rentals), and Division 43 capital works deductions on the construction cost generally run at 2.5% a year. Eligibility depends on the asset, when it was first used or installed, and the purchaser, so get a quantity surveyor's schedule. Against that sit three of the tests above: a developer margin lowers the land share (test 4), new stock often sits in a supply pipeline (test 3), and resale can be slow when many similar dwellings complete together (test 12). Our new-build carve-out modelling estimates how large a premium the tax advantages can justify.

How do you use a buyer's market without buying a weak asset?

The cheap-but-weak trap

Large discounts often sit on properties with a problem the market has already noticed. Beyond the walk-away signs in the decision table below, watch for:

• a flood, bushfire or heritage overlay that affects insurance, finance or use;
• strata records showing defect claims, a thin capital works fund or a special levy;
• repeated price cuts at several times the local days on market, with no explanation.

Terms worth asking for

• Finance condition tied to formal approval and a satisfactory valuation, with enough days for the bank to value.
• Building and pest condition, plus a satisfactory strata report for strata title.
• Settlement timing that suits your finance, or a quicker settlement traded for price if the vendor needs speed.
• Auction campaigns: a written pre-auction offer with your conditions when a campaign is struggling, or first chance to negotiate as the highest bidder if it passes in (rules differ by state). A contract signed at auction is generally unconditional.

Cooling-off rights are set by each state and generally do not apply at auction. Our negotiation guide covers offer tactics.

A due-diligence sequence

Source: our framework. Contract terms, cooling-off and auction rules vary by state; take legal advice on the contract.

Do you need a buyer's agent?

Buyers' agents are licensed under state real estate laws and act for the buyer. Ask whether they receive any commission, referral fee or rebate from vendors, developers or selling agents, and avoid "free" advisers paid by developers. Our off-market and buyer's agent guide covers fees. With Cotality's national total listings up a fifth on a year earlier, off-market access alone is a weaker reason to pay than it was in early 2026.

Which criteria matter most for your situation? Five profiles

These are illustrative, hypothetical profiles. Names and figures are invented; none is a recommendation.

Profile 1: First investment, Brisbane renter

Situation: Mia, 34, earns $145,000, rents in Brisbane and has $160,000 saved. She is looking at established houses around $700,000 in Ipswich, where PropTrack medians fell about 10% over the quarter in suburbs such as Redbank Plains.

Reasoning: Rental demand passes in postcode 4301. A 20% deposit ($140,000) plus about $24,500 of Queensland transfer duty already exceeds her savings, leaving nothing for a pre-tax shortfall near $20,000 a year, and as a post-cut-off established purchase her salary offset stops on 1 July 2027.

Strategy: Lower the price band, or borrow more with lenders mortgage insurance only if a 12-month buffer at the stress rate remains. Check each street against the Ripley Valley pipeline.

Profile 2: Equity-rich Sydney owners tempted by inner-city units

Situation: Daniel and Priya have $600,000 of usable equity in their Sydney home, and an agent has floated a pre-auction price for an inner-city unit 8% below the original guide.

Reasoning: The discount is real, but Gate 1 fails in postcodes like 2017 (SQM vacancy 4.37%, unit asking rents falling), and new completions in the precinct raise the supply flag.

Strategy: Revisit when vacancy has stopped rising for three months, or switch to an older boutique block with a higher land share in a postcode that passes.

Profile 3: Self-employed, needs close to neutral cash flow

Situation: Sam, a self-employed Adelaide electrician with variable income, wants a property that costs him little each month and is looking at houses around $670,000 in the city's north.

Reasoning: Rental demand passes in postcode 5112. But an indicative gross yield near 4.1% (postcode asking rent ÷ suburb median value) is far below the 7.6% pre-tax break-even at 80% LVR, and lenders may assess his income conservatively.

Strategy: Even at 60% LVR the break-even is about 6.1%, so he should budget for a modest shortfall, model a lower rent, and ask a broker how lenders treat his income before signing.

Profile 4: High-income buyer considering a new build for the tax treatment

Situation: Grace earns $250,000 and is weighing a new townhouse in a western Melbourne growth corridor because new dwellings keep the salary offset after 1 July 2027.

Reasoning: The tax treatment is real under the Act, but the definition of "new" sits in a Bill. Postcode 3029 fails Gate 1 at 3.82% vacancy, the estates around Tarneit and Truganina raise the supply flag, and the developer margin lowers the land share.

Strategy: Measure the premium against resales of two- to five-year-old townhouses nearby, confirm eligibility with a tax adviser before exchange, and look for new stock in a postcode where vacancy passes.

Profile 5: Portfolio holder with grandfathered properties

Situation: Tom and Elena own three investment properties bought before 12 May 2026, one a unit with weak rent growth, and are considering a fourth while prices are down.

Reasoning: Their three properties keep negative gearing while they own them. Selling one to fund a new established purchase swaps a grandfathered asset for a quarantined one, in a market where the weakest asset is hard to sell well.

Strategy: Run the weakest property through the Sell or Hold Planner first. Buy a fourth only if it passes the gates on pre-tax cash flow and the portfolio buffer covers all four shortfalls at the stress rate.

Decision framework, risks and what would change our view

Buy, keep looking or walk away

Source: our framework; thresholds are our rules of thumb applied with the data sources in the twelve-test table.

Risks and mitigations

Source: NAB Residential Property Survey Q3 2026; Bloomberg data via ABC News (21 October 2026); SQM Research; ABS Labour Force, September 2026; mitigations are our analysis.

The case for waiting

The gates screen for rental risk and resale depth and say nothing about where prices go next. If respondents to NAB's survey are right about a 4.2% fall over the next year, our $698,000 house would cost about $29,000 less in a year, and waiting would also save a year's pre-tax shortfall of about $20,800. Against that, today's discounts, choice and conditions may narrow if the market turns, which is why the tests ask whether you can hold through further falls.

What would change this guide's view

The approach holds while discounts and selling times stay elevated. It would change if Cotality's capital-city discount narrowed toward 3% and days on market fell for several months (buyers' bargaining power fading); if SQM vacancy rose above 2.5% in the smaller capitals, now below 1%; if the cash rate went beyond 4.85%, pushing the stress rate above 7.00%; or if the new-dwelling definition passed in a materially different form.

The Bottom Line

Capital-city homes took 39 days to sell in September and vendors gave up a median 4.4%, so buyers hold the bargaining power. The cash rate is 4.60% with a November rise possible, and the tax rules for established purchases change on 1 July 2027.

That puts the weight on choosing the asset. In our example the discount is worth about $1,860 a year in cash flow, and one vacant month costs more than that. Screen on rental demand and supply first, test holding cost before tax, and use the time and conditions a buyer's market offers to finish due diligence before the contract goes unconditional.

What to monitor: the RBA decision on 3 November, SQM's October vacancy (due mid-November), Cotality's final clearance rates, discounts and days on market, and the Tax Reform No. 3 Bill.
