Negative Gearing Changes 2026: 5 Property Valuations Investors Should Get Before 1 July 2027

The negative gearing changes 2026 are expected to make property valuations more important for investors who are deciding whether to hold, sell, refinance, restructure or transfer property before the new rules commence. A professionally prepared valuation can help establish a defensible market value, support tax modelling and create a stronger paper trail for future CGT, lending and compliance decisions.

Labor's 2026–27 Federal Budget delivered the most significant overhaul of Australian property taxation in a generation. From 1 July 2027, negative gearing will only apply to newly built investment properties, and the 50% Capital Gains Tax (CGT) discount will be replaced with an indexation method for new investments. Properties acquired before that date are grandfathered under the current rules, which makes the next twelve months the most valuable decision window Australian property investors have had since the Howard-era tax changes in 1999.

Every major investor decision between now and 30 June 2027, whether to hold, sell, restructure, transfer or refinance, needs to be modelled against a defensible, professionally prepared market valuation as at a specific date. This guide sets out the five valuations every Australian property investor should consider getting before Labor's reforms take effect, why each one matters, and the timeline you should be working to.

Get these wrong, and you risk paying tens of thousands of dollars in avoidable CGT, losing access to legitimate negative gearing entitlements, or ending up in a dispute with the ATO over a cost base that can't be substantiated.

What's actually changing on 1 July 2027

A quick refresher: from 1 July 2027 negative gearing will be restricted to new builds for any investment property acquired after that date, and the 50% CGT discount for individuals will be replaced with an indexation method for any asset acquired after the same date. Existing assets are grandfathered. The cut-off is tied to acquisition date, not sale date. For a deeper walkthrough of the reforms, see our analysis of the 2026 Federal Budget changes for property valuations and the Labor negative gearing changes investor guide.

In practice, every Australian investor now has a decision to make about each property in their portfolio (hold, sell, restructure, or refinance), and every one of those decisions needs a number. That number is a market valuation.

Why property valuations matter under the negative gearing changes 2026

The negative gearing changes 2026 make independent property valuations more important for investors who are deciding whether to hold, sell, refinance, restructure or transfer property before 1 July 2027. A professionally prepared valuation gives your accountant, lender or adviser a defensible market value to work from, rather than relying on agent appraisals or automated estimates.

Negative gearing changes 2026: investor valuation checklist

1. The baseline portfolio valuation

What it is: A market valuation of every investment property you currently own, prepared by a Certified Practising Valuer (CPV) as close as possible to 30 June 2027 (or earlier if you're planning a transaction sooner).

Why it matters: Your future tax decisions (sell, hold, transfer, depreciation backdating, insurance) all depend on knowing what each property is actually worth right now. A baseline portfolio valuation establishes that record formally, by an independent third party, with full documentation. Bank valuations, agent appraisals and CoreLogic estimates aren't accepted by the ATO for tax purposes and won't survive an audit.

Example: A Sydney investor with three properties commissions short-form valuations for all three in early 2027 for around $1,500–$2,000. The reports become the foundation for every subsequent CGT, restructure, refinance and depreciation decision over the next decade.

Best type: Short-form market valuation, or long-form valuation for complex properties.

2. The sell-vs-hold modelling valuation

What it is: A market valuation used as the basis for modelling the CGT outcome of selling now (under the 50% discount) versus selling later (under the indexation method, if you re-buy after 1 July 2027, or holding indefinitely under grandfathering).

Why it matters: The 50% CGT discount is enormously valuable, for an investor in the 37% marginal bracket selling a property with a $400,000 gain, the difference between the current discount and a worst-case indexation outcome can be tens of thousands of dollars. But you can't model the decision without an accurate, defensible value today. Agent appraisals aren't sufficient, accountants need a CPV-grade figure to run projections that hold up to ATO scrutiny. See our detailed guide on property valuations for capital gains tax purposes for the methodology requirements.

Example: A Melbourne investor bought an apartment in 2014 for $480,000. An independent valuation in 2026 confirms a market value of $880,000. The accountant then models sell-now (50% discount), sell-in-2030 (grandfathered), or transfer to a family trust before 1 July 2027, all anchored to the $880,000 baseline.

Best type: Long-form market valuation (the ATO requires defensible methodology for any CGT-related figure).

3. The related-party transfer or restructure valuation

What it is: A formal market valuation prepared for the purpose of transferring an investment property to a spouse, partner, family trust, SMSF or company before the 1 July 2027 deadline.

Why it matters: Many investors will look to restructure ownership before the reforms hit, transferring a property held in a high-income spouse's name into a family trust, or moving residential property into an SMSF. Any related-party transfer triggers stamp duty (see our valuations for stamp duty guide) and is treated as a CGT event, both of which require an independent market valuation under ATO and state revenue office rules. You can't use a "nominal" figure between related parties. The estate planning, divorce and SMSF post covers the related compliance situations in more depth.

Important: Restructures completed after 1 July 2027 create new acquisitions that lose grandfathering. State revenue offices and SMSF auditors also have dating rules (typically within 90 days of transfer), so planning needs to allow for that.

Best type: Long-form valuation explicitly addressed to the related-party transfer purpose.

4. The refinance and equity-release valuation

What it is: A market valuation used to refinance an existing investment loan, release equity for further investment, or restructure debt while current serviceability rules and full negative gearing still apply.

Why it matters: Lender serviceability calculations currently assume that negative gearing offsets investment property losses against your overall taxable income. Once Labor's reforms take effect, that assumption changes for new investment loans on properties acquired post-1 July 2027. The practical effect: investors who want to release equity from existing (grandfathered) properties to fund a new build (which retains negative gearing under the new rules, plus full depreciation schedule deductions) should be moving in 2026–27, not 2028.

A bank valuation alone is rarely the best tool, bank valuations come in 5–15% under market value (see our bank valuation vs market value guide). An independent valuation prepared for you can support a higher refinance number and unlock a larger deposit for a new-build investment.

Best type: Short-form valuation, often in conjunction with the bank's panel valuation. A desktop valuation is useful for indicative refinance modelling.

5. The pre-grandfathering record valuation

What it is: A formal, dated market valuation report kept on file as evidence that you owned a property of a particular value before 1 July 2027. This is the document you'll wave at the ATO in 2032 if your cost base or ownership history is ever questioned.

Why it matters: Audit risk on grandfathered assets will increase once two CGT regimes run in parallel. Title records prove date of acquisition, but a contemporaneous independent valuation prepared in 2026 or 2027 strengthens the audit trail and protects you in any future family law, deceased estate or SMSF audit situation.

Best type: Short-form market valuation, archived with your tax records and SMSF compliance records.

The timeline

A realistic plan for most Australian investors:

• Now to December 2026, strategy phase. Engage your accountant. Identify which properties are sell, hold, restructure or refinance candidates. Order indicative desktop or short-form valuations to feed the modelling.

• January to June 2027, execution phase. Commission long-form valuations for any sale, transfer or restructure. Lodge state revenue office documents. Complete refinances. Update SMSF compliance records.

• 1 July 2027 onwards, record phase. Archive a final pre-deadline valuation for every property still held as permanent evidence of pre-grandfathering value.

Demand for CPV-prepared valuations is expected to spike in the lead-up to the deadline, particularly across Sydney, Melbourne, Brisbane and Perth. Investors leaving this until Q2 2027 will find both valuers and accountants stretched thin.

Who should act urgently

• High-income earners with sizeable unrealised gains, the CGT discount change disproportionately affects you.

• Anyone planning a related-party restructure, spousal transfers, trusts and SMSF moves take months.

• Investors with old depreciation gaps, a portfolio review is also a natural moment to commission a retrospective property valuation and an updated depreciation report.

• Investors thinking about new-build investment, the post-2027 advantage shifts heavily to new builds, which means a QS report on the build cost is critical for maximising deductions.

• SMSF trustees, already have an annual SMSF valuation obligation; a pre-deadline CPV report closes the compliance gap and creates a grandfathering record in one document.

Frequently asked questions

Do existing investment properties really keep the 50% CGT discount forever? Yes, under the current grandfathering arrangements announced in the 2026 Budget, properties acquired before 1 July 2027 retain the 50% CGT discount on disposal regardless of when you sell. The reform applies based on the acquisition date of the asset, not the sale date.

If I restructure my property into a family trust before 1 July 2027, does it keep grandfathering? This is where it gets technical. A transfer to a trust is a CGT event and a new acquisition for the trust. Whether the trust itself receives grandfathered treatment depends on how the legislation is ultimately drafted. Speak to a tax adviser before any restructure, the legislative detail is still being finalised at the time of writing.

Can I use a real estate agent's appraisal instead of a valuation? No. Agent appraisals are sales estimates, not independent valuations, and are not accepted by the ATO, state revenue offices, SMSF auditors or courts. For any tax or compliance purpose, you need a Certified Practising Valuer's report. See property valuation vs appraisal in Australia for the full distinction.

How much does a property valuation cost? Short-form market valuations for residential property typically range from $450 to $700. Long-form valuations for CGT, family law, SMSF or related-party transfer purposes generally range from $600 to $1,500. Desktop valuations are cheaper (often from $295) but are not accepted by the ATO and shouldn't be used for any of the five purposes in this guide.

Will commissioning a valuation now lock in my value for CGT? No. CGT is calculated based on the actual sale price (or the deemed market value at the time of a CGT event), not on a historical valuation. But a contemporaneous valuation is critical evidence supporting your cost base, especially for properties acquired or restructured close to the 1 July 2027 deadline.

Should I get valuations for properties I'm not planning to sell? Yes, for two reasons. First, the strategic landscape may change, an unplanned sale or family event may force a decision later. Second, a 2026 or 2027 valuation creates a permanent record of pre-grandfathering ownership that protects you against audit disputes long into the future.

What if Labor doesn't pass the legislation? The reforms were a flagship Budget measure and have been confirmed in the May 2026 Budget papers. Implementation timelines or thresholds could shift, but the direction is clear. Acting on the basis that the reforms will come into effect is the prudent default, and any valuation commissioned now retains its value regardless of legislative outcome.

The bottom line

The next twelve months represent a one-time window for Australian property investors to position themselves under the current tax rules before they change permanently. Every major decision in that window (sell, hold, restructure, transfer, refinance, document) depends on an accurate, defensible market valuation prepared by a Certified Practising Valuer.

Five valuations, properly sequenced and properly documented, can save Australian investors tens or hundreds of thousands of dollars in CGT, locked-in lending capacity, missed depreciation, and audit defensibility. The cost of getting them is a tiny fraction of the upside.
