Budget changes and rentvesting: how to test if it still works

Rentvesting can still work after the 2026–27 Budget, but you now have to assume little or no negative gearing benefit on new established properties and be confident the numbers hold on pre‑tax cashflow. If your rentvesting plan only works because the tax office chips in, it’s probably not safe under the new rules.

Compare your lifestyle rent and investment numbers side by side before committing.

Quick refresher: what is rentvesting now?

Rentvesting means you rent where you want to live, and buy where the numbers work.

You might:

• Rent a $900/week place near the city or beach, and
• Buy a $650,000 investment in a solid growth corridor.

You get lifestyle where you live, and potential capital growth where you invest.

But after 12 May 2026, negative gearing on many established investments will be quarantined, so you can’t freely offset rental losses against your salary from 1 July 2027.

How Budget changes hit rentvesting decisions

From the 2026–27 Budget measures:

1. Established properties bought after 12 May 2026 – rental losses will generally be quarantined to rental income from 1 July 2027, not offset against wages.
2. New builds that qualify – can still access negative gearing and the CGT concessions, but should never be bought on tax benefits alone.
3. Existing pre‑12 May 2026 holdings – broadly grandfathered under current rules, though CGT is also shifting.

That means a rentvesting purchase after Budget night 2026, if it’s an established dwelling, must be assessed as if negative gearing is worth $0 to your household (knowledge fact 2).

Simple worked example

• Purchase price: $650,000 established unit (post‑12 May 2026)
• Loan: $617,500 (95% LVR + LMI rolled in), P&I, 6.5% rate
• Repayments (30 years): about $3,900/month
• Rent: $580/week ≈ $2,513/month
• Other costs (rates, strata, insurance, maintenance): $700/month

Pre‑tax cashflow:

• Rent: +$2,513
• Interest + principal: −$3,900
• Costs: −$700
• Net before tax: −$2,087/month

Under old rules, a big chunk of that loss could reduce your taxable income.

Under new rules for many established properties, that $2,087 loss mostly stays trapped in the rental bucket.

If your household budget can’t comfortably wear an extra ~$500/week drain, the deal fails the rentvesting test.

A decision framework you can use this week

Step 1: Test it on pre‑tax cashflow only

For any potential rentvesting property, run it three ways:

1. Base case today – current interest rates, realistic rent, all costs.
2. RBA +1% – increase the rate by 1%.
3. RBA +2% – increase by 2% (roughly APRA’s 3% buffer from your actual rate).

The strategy still stacks up if:

• You can carry the loan at +2% without using credit cards or cutting essentials, and
• The property is close to neutral or mildly negative before tax.

This is exactly the stress‑testing approach we use for geared investments in /insights/rentvesting-with-gearing-live-where-you-want-invest-where-it-works.

Step 2: Choose the right property “bucket”

Post‑2026 there are three practical buckets (see /insights/negative-gearing-after-budget-what-still-works-what-doesnt):

• Grandfathered holdings – bought before 7:30pm, 12 May 2026.
• Post‑12 May 2026 established dwellings – losses quarantined.
• Qualifying new builds / exemptions – negative gearing largely retained.

For new rentvestors:

• Don’t bank on large tax refunds from established properties bought after Budget night.
• For new builds, still test the deal as if tax benefits are a bonus, not the core reason.

Step 3: Compare “buy where you live” vs rentvesting

Use a simple comparison this week:

• Scenario A: Buy a home to live in where you want.
• Scenario B: Rent that home, buy an investment where the numbers are stronger.

Key questions:

• Which scenario gives you a lower total cash outflow each month (rent + investment shortfall vs home loan P&I + costs)?
• Which one gets you into the market with a safer buffer (3–6 months of living costs and at least 3 months of loan repayments in offset)?
• How does each option affect your borrowing capacity for future moves (business, upgrading, kids)?

If Scenario B still gives you:

• Better lifestyle,
• Similar or lower monthly strain, and
• Access to a fundamentally good asset,

then rentvesting still stacks up.

Serviceability and risk: what lenders will care about

Lenders already apply at least a 3% serviceability buffer over your actual rate.

Post‑Budget, they’ll look even harder at:

• How much of your rent they count (often 70–90%),
• Your existing rent obligations,
• Other debts and credit cards,
• Reliance on tax refunds that may shrink.

For rentvestors, a common trap is:

• High personal rent in a prestige area, plus
• A heavily negative investment.

On paper, that can crush your borrowing power.

Loan structure matters more now

Things to tighten up before you commit:

• Use P&I on investment debt unless there’s a clear, modelled reason for interest‑only.
• Maximise genuine offset accounts rather than redraw.
• Keep home and investment loans clearly separated for tax clarity.

A CPA‑grade mortgage broker can model after‑tax cashflow under the new rules so you’re not guessing. See how that works here: /insights/cpa-mortgage-broker-after-tax-outcomes-new-rules.

Who should still consider rentvesting?

Rentvesting still makes sense if you:

• Have stable income but are priced out of the area you want to live in.
• Value lifestyle and schooling now, but don’t want to delay investing.
• Are self‑employed and want to separate home and business risk from investment.

It’s much less attractive if:

• You’re stretching to the limit on both rent and loan repayments.
• Your chosen property only looks okay once you plug in old‑school negative gearing benefits.
• You’d lose sleep over a few months of vacancy or rate rises.

FAQs

Is rentvesting still worth it without full negative gearing?

Yes, if the property is strong on fundamentals and close to neutral before tax. The new rules simply remove the crutch of large salary‑offset losses for many established properties, forcing you to buy assets that hold their own. If your deal collapses without big tax refunds, it probably wasn’t worth doing.

Should I only buy new builds to keep negative gearing?

No. New builds may keep negative gearing benefits, but many also carry higher build‑quality and valuation risks. Start with location, demand and realistic rents, then layer in tax as a secondary consideration. A mediocre new build with tax perks can still underperform a quality established property with modest or no tax benefits.

How big a buffer do I need as a rentvestor after the Budget?

Aim for at least 3–6 months of total living costs plus 3 months of loan repayments in your offset, especially if you’re self‑employed or on variable income. The more you’re relying on one income, the closer your numbers are to the line, or the more negatively geared you are, the larger that buffer should be.

Key takeaways

• Treat negative gearing as upside only; the property must work on pre‑tax cashflow.
• Choose assets by fundamentals and stress‑test at +2% interest and periods of vacancy.
• Make sure your rent + loan setup still leaves room for buffers and future goals.
