Should I Buy a House Now or Wait Until After 1 July 2027?

Published 14 May 2026 — two days after the federal budget. Since 7:30pm on Tuesday 12 May, almost every first home buyer in Australia has been asking the same question: should I sign a contract now, or wait until after 1 July 2027 when negative gearing tightens and the CGT discount changes?

The honest answer is that it depends on five things, none of which are the budget date itself. The most expensive decision an FHB can make in 2026 is not "buy at the wrong time" — it is "wait for a perfect time that never arrives". Treasury, the RBA and CoreLogic all agree the 12 May 2026 reforms will soften established-property prices by roughly 1.5–2% over five years versus the no-reform baseline [source: treasury.gov.au]. That is a real number. It is also smaller than 12 months of Sydney rent.

This guide is a decision framework, not a prediction. We walk through the five variables that actually move the answer, run a $750,000 Sydney worked example for the cost of waiting, fork the recommendation by buyer archetype, address the "what if prices crash" objection on its own terms, and finish with a 12-question FAQ. If you only have 60 seconds, the TL;DR below is the whole framework.

TL;DR — The framework, not the answer

There is no universal "buy now" or "wait" answer for Australian FHBs in 2026. The right call depends on these five variables, weighted in roughly this order:

1. Are you actually ready? Pre-approval, deposit in cash, stable income, and a property you would be happy to live in for at least 5–7 years. If any of these is "no", the budget date is irrelevant — keep saving.
2. What property type would you buy? The budget creates opposite incentives for established versus new builds. Treasury models established prices softening 1.5–2% and new-build completions rising 4–6% by mid-2031 [source: treasury.gov.au]. If you are buying a new build, waiting for the investor tax change to bite means more competition, not less.
3. Where in the RBA rate cycle are you? The cash rate sits at 4.35% after the 5 May 2026 hike from 4.10% [source: rba.gov.au]. Big-4 variable rates are 5.95–6.20%. Forward markets are pricing the first cut for late 2026 or early 2027. Buying now and refinancing later is the standard playbook.
4. Are you eligible for a scheme that may close? Help to Buy has 10,000 places per year and a $100K/$160K income cap [source: housingaustralia.gov.au]. If you qualify today, waiting risks ineligibility (income creep) or oversubscription.
5. What is your alternative? Waiting is not free. It is renting. On a typical Sydney FHB target, 12 months of rent is $30,000–$40,000. Treasury's 1.5–2% cumulative-over-5-years softening on a $750K home is $11,000–$15,000. The maths usually favours buying now if you are ready.

Run yourself through those five and you will already have a directional answer. The rest of this guide gives you the inputs and the worked maths to validate it.

Why "wait until 1 July 2027" is the wrong question

The 12 May 2026 budget made two big changes that triggered the timing debate. Negative gearing is being abolished for new investor purchases of established residential property from 1 July 2027. The 50% CGT discount is being replaced by cost-base indexation plus a 30% minimum tax on capital gains from the same date. Existing investors are grandfathered indefinitely [source: budget.gov.au]. Our companion guide, Federal Budget 2026 — what it means for first home buyers, walks through the rule changes in plain English.

Neither change applies to owner-occupier first home buyers. Your own home does not pay capital gains tax (the principal place of residence exemption is untouched). Your loan repayments are not deductible to begin with, so the negative-gearing tax shield was never available to you anyway. The reform only matters to you indirectly — through what it does to investor competition on the homes you are bidding for.

Treasury's central modelling, released alongside the budget, estimates the combined reforms will reduce established-property prices by 1.5–2% relative to the no-reform baseline over five years, while raising new-build dwelling completions by 4–6% [source: treasury.gov.au]. Grattan Institute's parallel analysis puts the established softening at 1–3% [source: grattan.edu.au]. AFR's housing economics columnist Karen Maley independently arrives at 1.5–2.5% [source: afr.com]. Nobody serious is forecasting a crash.

The largest behavioural shift is expected before 1 July 2027, not after, as investors reposition portfolios away from established stock toward new builds [source: treasury.gov.au]. That means the softening is most likely to show up in auction-clearance data from late 2026 through to settlement in mid-2027 — and may have largely played out by the time the legislation goes live. Buyers waiting for "the dip" on 2 July 2027 may find the dip already happened.

The 5 timing variables that actually matter

1. Are you ready to buy?

"Buy-ready" is a specific checklist, not a feeling. The five inputs:

• Pre-approval in hand, ideally with two lenders so you can move on auction day. See our home loan pre-approval guide for the 60–90 day window and what triggers a re-assessment.
• Deposit plus costs in cash — at least 5% of purchase price for the First Home Guarantee, plus stamp duty (state-dependent — use our stamp duty calculator), plus conveyancing (~$1,500), plus building & pest ($500–$1,000), plus moving ($1,000–$3,000). Budget on 7–10% all-in for an established home.
• Stable income. Lenders want six months of consistent payslips, or two tax returns if you are self-employed. A job change inside the last six months is the single most common reason finance falls over after pre-approval.
• A property you would be happy to live in for 5–7 years. Selling costs (agent commission, marketing, stamp duty on the next purchase, conveyancing) eat 7–10% of value. A 5-year hold is the minimum at which Australian capital growth historically out-runs those frictions.
• Mental readiness. A 30-year mortgage is the largest financial commitment most Australians will make. If you are not sleeping over the decision, the budget date is not your problem.

If any of those five is "no", the cost-of-waiting maths below does not save you — fix the readiness gap first.

2. Property type: established versus new build

The budget creates structurally opposite price pressures on the two property types. Treasury's modelling, repeated in the Reserve Bank's May 2026 Statement on Monetary Policy, treats this as the central transmission channel of the reform [source: rba.gov.au]:

• Established property: investor demand falls because negative gearing is no longer available on new purchases from 1 July 2027 and the CGT treatment becomes less generous. Treasury models a 1.5–2% price softening over five years against the no-reform baseline.
• New builds: investor demand rises because the negative-gearing carve-out for newly constructed property creates a tax-advantaged class of investment. Treasury models a 4–6% increase in dwelling completions, plus modest upward pressure on new-build prices.

If your target is a house-and-land package, an off-the-plan apartment, or any other never-lived-in dwelling, the case for waiting is weaker — investor competition on new builds will rise, not fall. The case for locking in a 2026 price (and where possible a 2026 build contract) is materially stronger. Our house-and-land packages guide covers the mechanics of locking a land settlement now and a build price later.

If your target is a 1970s brick veneer in middle-ring Sydney or a 1990s walk-up unit in inner-north Melbourne, the established-stock softening might modestly help you — but as we show in the cost-of-waiting maths below, the rent you pay while waiting usually eats the gain.

3. The RBA rate cycle

The Reserve Bank lifted the cash rate to 4.35% on 5 May 2026, up from 4.10% [source: rba.gov.au]. Big-4 variable owner-occupier rates moved to 5.95–6.20% inside a week. The cash-rate decision was driven by an unexpectedly hot March 2026 quarterly CPI print of 4.1% and trimmed-mean inflation at 3.6% — both above the RBA's 2–3% target band [source: abs.gov.au]. Forward overnight-index-swap markets are now pricing one further hike with 30% probability before the first cut, which traders see as likely in Q1 2027 [source: rba.gov.au].

For the buy-now-versus-wait decision, two things matter:

• Buying at a higher rate is normal — you refinance later. If you settle in 2026 at 6.10% variable and the RBA delivers two cuts of 25bp each through 2027, your rate naturally drops to 5.60%. You do not need to wait outside the market to capture rate cuts; they pass through to existing variable-rate borrowers automatically. Our fixed vs variable home loan guide covers when to lock and when to ride.
• Borrowing capacity is what waiting buys you. Every 25bp rate cut lifts a typical FHB's borrowing power by roughly 2.5%. If you can fund the home you want at today's rates, waiting for capacity uplift is unnecessary. If you cannot, then waiting and saving more deposit (not just waiting) is the play. Use our borrowing power calculator to see your current envelope and what one or two cuts would unlock.

4. Scheme eligibility windows

Two federal schemes have time- or quota-bound windows that may close on you:

• Help to Buy: 10,000 places per year for four years, capped through 30 June 2029 [source: housingaustralia.gov.au]. Income caps are $100,000 single and $160,000 joint. If your income is creeping toward the cap, or you are on a single-income household that is becoming dual, waiting risks ineligibility. If the program is oversubscribed in 2026 (the Q1 2026 quota filled in 10 weeks), the 2027 allocation may also fill fast.
• First Home Guarantee: Unlimited places, no income caps — the 1 October 2025 expansion was confirmed in the 12 May budget [source: budget.gov.au]. Less time-sensitive, but if you are weighing it against Help to Buy, our Help to Buy vs First Home Guarantee comparison covers the decision tree.

State stamp-duty concessions are also a moving target. NSW's $800K full-exemption threshold for FHBs has held since 1 July 2023; Victoria's $600K threshold since 2017; Queensland's $700K since 1 July 2024. None has been touched in 2026 to date, but state budgets typically land in May–June and have form for adjusting thresholds.

5. Your alternative — the cost of not buying

Waiting is not free. It is renting. CoreLogic's national rental index rose 7.4% in the 12 months to April 2026, with capital-city units up 8.9% [source: corelogic.com.au]. The median asking rent on a 2-bedroom unit in inner Sydney is now $720 per week. In Brisbane, $640. Melbourne, $580. Adelaide, $545. Every month you wait, that money pays your landlord's mortgage, not your own.

The cost-of-waiting worked example below makes this concrete.

Cost of waiting — a $750,000 Sydney FHB worked example

Two identical buyers. Same job. Same deposit. Same target — a $750,000 unit in inner-west Sydney. Alice settles in June 2026. Bob waits 15 months and settles in September 2027. We assume Treasury's 1.5% established-property softening lands fully on Bob's purchase price.

The maths: Bob saves $11,250 on the purchase price thanks to Treasury's modelled softening. He pays $42,250 in rent and misses $9,750 of equity-building principal repayments. Net, he is $31,000 behind Alice at settlement. For Bob to come out ahead, the established-property softening would need to be 5.7% over 15 months — three times Treasury's central case and well outside Grattan's, AFR's and the RBA's range.

Three caveats:

• If your local market is overheated relative to fundamentals (an established-suburb price-to-income ratio above 9, or 12-month growth above 12%), the case for waiting strengthens — but only if the softening lands in your specific suburb.
• If you are not financially ready, the waiting period is not "waiting for the budget date" — it is "saving more deposit to qualify". That is always the right call.
• If you are buying a new build, this framework inverts. New-build investor demand rises after 1 July 2027, so waiting risks higher competition and modest price rises.

Decision tree — what should YOU do?

Use this archetype tree to land your directional answer.

Archetype A: Pre-approved, deposit ready, established target

Recommendation: buy now. The cost of 12–15 months of rent is materially larger than Treasury's modelled price softening. If you can find a property you are happy to live in for 5–7 years and your finance clears, the budget is not a reason to wait.

Archetype B: Pre-approved, deposit ready, new-build target

Recommendation: buy now, lock the contract. Investor demand on new builds will rise, not fall, after 1 July 2027 because of the negative-gearing carve-out. Locking a 2026 build contract — especially in a house-and-land package where you can fix the land settlement and the build price separately — is the strongest case for action across all archetypes.

Archetype C: Help to Buy-eligible (under $100K single / $160K couples and single parents)

Recommendation: apply this quarter, do not wait. The 10,000 annual places filled in 10 weeks in Q1 2026. Income creep, partner-income changes or budget tightening in 2027 are all real risks. If you qualify today, lock it in. Compare against the First Home Guarantee using our side-by-side comparison.

Archetype D: Saving toward a deposit, not yet pre-approved

Recommendation: keep saving, do not try to time the market. Your binding constraint is deposit and serviceability, not the budget date. Use the next 12–18 months to build deposit (consider the First Home Super Saver Scheme for concessional-rate saving), kill consumer debt (see credit cards and borrowing power), and get formal pre-approval the moment you cross the threshold.

Archetype E: Just lost pre-approval after the 5 May rate hike

Recommendation: re-shop lenders, re-broker, do not assume you are locked out. Big-4 servicing assessment rates moved up 25bp in line with the cash rate. Smaller lenders use slightly different buffer assumptions and may still clear you. A specialist FHB mortgage broker can re-rate you across 30+ lenders in a day. If borrowing capacity is genuinely below your target, drop to Archetype D for 6–12 months.

Archetype F: Single parent with dependents

Recommendation: 2% deposit Family Home Guarantee, buy now. The Family Home Guarantee needs only a 2% deposit, has no LMI, no income cap, and is open to single parents who do not need to be first home buyers. The waiting maths is the same as Archetype A, but with a much smaller deposit hurdle.

"But what if prices crash?" — the objection on its own terms

The "prices will crash" argument has been a constant feature of Australian housing commentary since 2009. It has not been right yet. But the question deserves an honest treatment rather than a dismissal.

Three things to test against the data:

• What does the modelling say is the worst case? Treasury's central estimate is a 1.5–2% softening against the baseline; the AFR's upper bound is 3% [source: afr.com]. Grattan's analysis goes up to 3.5% in inner-suburban Sydney and Melbourne, where investor concentration is highest [source: grattan.edu.au]. None of the credible models forecast a fall below 5%.
• What would it take for prices to actually crash? Historically, Australian house-price falls of more than 7% over 12 months require unemployment to rise above 7% (we are currently 4.1%), or a sustained 200bp+ rate hike from here. Neither is in any major forecaster's base case [source: rba.gov.au].
• What is the cost of being wrong? The asymmetry runs both ways. If you wait and prices rise 3% (CoreLogic's projection for the next 12 months absent the reform), you pay more and 15 months of rent. If you wait and prices fall 3% on a $750K home, you save $22,500 — less than 12 months of Sydney rent. The downside scenario does not pay for itself.

The honest take: a crash is not impossible, but it is well outside the probability range of every model that took the 12 May budget seriously. Building your decision around it is the same shape of mistake as not buying insurance because your house has not burned down.

Other timing variables worth knowing

The budget date and the cash-rate cycle are the two big ones, but there are quieter timing inputs that move some buyers' decisions:

Season — auction vs private sale

Auction-heavy Sydney and Melbourne markets see roughly 60% of annual stock cleared in the spring (Sep–Nov) and autumn (Feb–Apr) selling seasons. Winter listings are thinner but competition is lower; summer is the dead zone. Buying off-market or via private treaty in July or January typically negotiates 1–3% better than at peak auction periods. Brisbane, Adelaide and Perth are private-treaty markets year-round; season matters less.

Personal life events

The single biggest predictor of regretting a property purchase is buying within 6 months of a major life change — new job, new city, marriage, divorce, baby. If anything in your personal life is in motion, the budget date is the wrong reason to act. Wait for stability, not for legislation.

End-of-financial-year tax timing

Settling before 30 June lets you claim that financial year's First Home Super Saver Scheme withdrawal sooner and (if relevant) finalises your taxable-income picture for the lender's serviceability assessment. Settling in July restarts your tax position. For FHBs the EOFY timing is a minor factor — not zero, but not decisive.

What FHBs should do this week — 3 action items

1. Get pre-approval today if you do not have it. Pre-approval is free and locks your borrowing capacity for 60–90 days. With the 5 May 2026 rate hike already absorbed by lender servicing models, today's pre-approval reflects today's reality. A specialist FHB mortgage broker can run you across 30+ lenders in a sitting. Our pre-approval guide walks through the exact documents you need.
2. Run the cost-of-waiting numbers for your specific situation. Use the borrowing power calculator and stamp duty calculator to model your purchase, then sanity-check against your current rent. If waiting 12 months costs you more in rent than the modelled softening saves, the answer is buy now.
3. If you qualify for Help to Buy, lodge the expression of interest this quarter. The 2026 quota is 10,000 places and Q1 filled in 10 weeks. Q3 places open 1 July 2026 [source: housingaustralia.gov.au]. Income caps are $100K single, $160K joint. If you are close to the cap, do not wait for a 2027 quota that may be tighter or oversubscribed.

Frequently asked questions

Should I buy a house now or wait until 2027 in Australia?

If you are pre-approved, have a deposit, and would be happy to live in the property for at least 5–7 years, the maths usually favours buying now. Treasury's central modelling of 1.5–2% established-property price softening over five years is materially smaller than 12–15 months of typical capital-city rent. The exception is a new-build target, where waiting risks more investor competition, not less — buy sooner not later.

Is now a good time to buy a house in Australia in 2026?

For prepared FHBs targeting established stock, yes — investor demand on established property is expected to ease over the next 12–24 months as the 1 July 2027 negative-gearing reform looms. For new-build targets, the next 12 months are likely the lowest-competition window before investor demand on new dwellings rises. The exception is buyers who are not yet pre-approved or are stretching financially — for them, no time is a good time.

How much will house prices fall after the 1 July 2027 negative gearing change?

Treasury's central modelling estimates established residential property prices will be 1.5–2% lower than the no-reform baseline over five years. Independent analysis from Grattan and the AFR puts the range at 1–3%. Critically, this is "softer than the baseline", not "1.5% nominal fall" — if the baseline trend is +3% per year, actual nominal prices may still rise 1–1.5% per year. New-build prices are forecast to firm slightly because the investor carve-out applies to them.

What is the cost of waiting 12 months to buy a house in Sydney?

On a $750,000 inner-Sydney unit purchase, 12 months of typical $650/week rent is $33,800. Missed equity-building (principal paid in year 1 of a 30-year P&I loan at 6.10%) is roughly $8,000. Total cost of waiting: ~$41,800. Treasury's modelled 1.5% price softening would save $11,250 — leaving you $30,000+ worse off for waiting a year. The maths is similar in Melbourne and Brisbane, smaller in Perth and Adelaide where rents are lower.

Should I wait for the RBA to cut interest rates before buying?

No — buy when you are ready, refinance when rates fall. Variable-rate borrowers capture RBA cuts automatically, so you do not need to wait outside the market to benefit. Forward markets are pricing the first cut for early 2027, but timing markets is notoriously unreliable. If you settle in 2026 at 6.10% and the RBA delivers two 25bp cuts in 2027, your rate naturally drops to 5.60% without any action from you.

Does the 12 May 2026 budget affect my first home purchase directly?

Not directly. Negative gearing applies only to investment properties, not the home you live in. The CGT discount change applies to investment property and other capital assets, not your principal place of residence. The First Home Guarantee remains unlimited with no income caps, and Help to Buy retained its 10,000 places per year through 30 June 2029. The budget affects FHBs only indirectly, through what it does to investor competition on the homes you bid for.

If I buy now, do I get grandfathered under the old rules?

You are an owner-occupier, not an investor, so the negative-gearing and CGT changes never applied to your own home in the first place — there is nothing to be grandfathered out of. Your principal place of residence is fully CGT-exempt at sale, before and after 1 July 2027. The grandfathering provision applies to existing investors with established investment properties under contract before 7:30pm AEST 12 May 2026.

What if I am buying a new build — should I still wait?

No — the case for buying a new build now is the strongest of all archetypes. The 12 May budget carved out newly constructed property from the negative-gearing abolition, which is expected to push investor demand toward new builds from 1 July 2027 onwards. Treasury models a 4–6% increase in dwelling completions. Locking a 2026 contract price (especially on a house-and-land package where you can settle the land and build separately) front-runs the investor competition.

What if I lose my job after I buy?

This is a real risk, but not a budget-date risk. Standard mitigation: a 3-month cash buffer in an offset account, mortgage protection insurance (typically $20–$50 a month for FHBs), and a serviceability cushion of 1–2% above current rates already baked into APRA's lender stress tests. The same risk applies whether you buy in 2026 or 2027. Waiting for "more job security" is rarely the right framing — most Australians never feel fully secure.

Should I use Help to Buy before it runs out?

If you qualify (under $100K single, $160K joint, citizen, owner-occupier, under state property price cap), yes — apply this quarter. The 10,000 annual places filled in 10 weeks in Q1 2026, and there is no guarantee future quotas will be increased or that eligibility caps will be unchanged. If you are weighing Help to Buy against the First Home Guarantee, see our side-by-side comparison.

What if the legislation does not pass before 1 July 2027?

Both the negative-gearing and CGT reforms are expected to clear the Senate by late 2026 — Labor has the numbers with Greens and crossbench support. Even if implementation is delayed by 6–12 months, the investor behavioural shift (repositioning toward new builds) has already started based on the budget announcement. From an FHB perspective, the answer to "buy now or wait" does not change materially with a delayed effective date.

How do I know if my market is overheated and waiting makes sense?

Two quick tests. First, median price-to-household-income ratio: above 9 is overheated (Sydney is currently ~10.5, Melbourne ~8.2, Brisbane ~7.5, Perth ~6.9, Adelaide ~7.1). Second, 12-month price growth: above 12% suggests near-term momentum that may cool. If your suburb scores high on both — and you are not yet pre-approved — waiting 6–12 months to save more deposit while the market cools is defensible. If only one is high, the rent cost usually still outweighs the wait.
