For years, the choice between buying a new build and an established home as an investment property was largely a matter of location, depreciation, and personal preference. The 2026 federal budget has changed that equation. With negative gearing now limited for established residential properties purchased after budget night, while remaining fully available for new builds, the tax position of these two property types has diverged materially overnight. At OM Financials, Shyam Maggo and the team have been fielding this exact question from clients since 12 May. Here is what every investor considering an investment property loan in Australia needs to understand about how this changes the lending decision.
What Exactly Changed: The Rule in Plain English
The rule is specific:
From 1 July 2027, investors who purchased established residential property after 7:30 pm AEST on 12 May 2026 can only deduct rental losses against other residential rental income or capital gains from residential property, not against salary or wages.
New builds are fully exempt: investors purchasing eligible new residential construction retain the full ability to negatively gear against all income, including salary, exactly as before.
Existing properties and those under contract before 7:30 pm on 12 May 2026 are fully grandfathered. Nothing changes for investors who already hold. The changes apply to new purchase decisions from Budget Night forward.
What Qualifies as a ‘New Build’ Under the New Rules?
An eligible new build under the proposed changes generally covers:
- Properties not previously sold, bought off the plan or newly constructed
- House-and-land packages built on previously vacant land
- Demolished and replaced properties only if replaced with a greater number of dwellings than were demolished
- Established homes being renovated: renovation alone does not qualify a property as a new build
The final determination of eligibility will depend on legislation that has not yet been passed as of the time of writing. Investors considering off-the-plan or house-and-land purchases should seek specific legal and tax advice before assuming they are eligible based on Budget Night announcements.
How This Changes the Investment Lending Decision
The investment property loan you take out for a new build versus an established home is different in several ways, and the budget has now made the tax dimension a primary factor in that decision for most investors. Here is how the two options compare across the dimensions that matter most for lending:
Investment Lending Comparison Post-Budget 12 May 2026
| Factor | Established Home | New Build |
| Negative gearing | Limited from 1 July 2027 for properties bought after Budget Night. Losses can only offset residential property income or be carried forward. | Retained. Losses can still offset other income, including salary. |
| CGT on sale | From 1 July 2027, cost-based indexation replaces the 50% CGT discount, with a 30% minimum tax on capital gains. | Investors may choose between the new CGT regime or the existing 50% discount. |
| Loan type required | Standard investment property loan. | May require a construction loan with progress draws if building. Off-the-plan or completed new homes may use a standard investment loan. |
| LVR at most lenders | Typically 80% for investment loans, or up to 90% with LMI, depending on lender policy. | Typically 80–90%, but some lenders may restrict off-the-plan purchases to lower LVRs. |
| Serviceability assessment | Some lenders may adjust how they treat negative gearing benefits for affected established properties. | Negative gearing benefits may still be considered by some lenders, depending on policy. |
| Valuation risk | Usually valued using comparable sales. | Off-the-plan purchases can carry settlement valuation risk if values move before completion. |
The Serviceability Shift: What Lenders Are Already Doing
This is the lending change most investors haven’t factored in yet; many lenders will no longer include negative gearing tax savings in serviceability calculations for established homes purchased after budget night. Under the previous framework, a negatively geared investor could have the tax benefit counted as assessable income, improving what the lender calculated they could repay. For established purchases after 12 May 2026, that calculation changes. For new builds, it does not.
For investors close to borrowing limits and in 2026, with the RBA cash rate at 4.35% and APRA’s DTI cap limiting lending at 6x income, this serviceability difference between new and established can genuinely shift whether an application is approved. This is a conversation OM Financials is having with investment property loan clients across NSW and Australia every week right now.
The Lock-In Effect: Why Existing Investors May Hold Rather Than Sell
One consequence of the budget that directly affects the investment property market is what CBA economists have called the ‘lock-in effect’. Grandfathered investors have a stronger incentive to hold their existing properties because selling means losing the grandfathered negative gearing treatment, and any future acquisition would be subject to the new rules. CBA projects this will reduce market listings and turnover in the short term. potentially softening some of the downward price pressure the reforms might otherwise create. For buyers targeting established properties, reduced listings may mean less choice, not lower prices.

Frequently Asked Questions
FAQ: Are investment properties I already own affected by the budget changes?
Answer: No, properties held or under contract before 7:30 pm on 12 May 2026 are fully grandfathered. Your existing negative gearing arrangement is unchanged until you sell. Only established properties purchased after that date and time are affected.
FAQ: Do new builds qualify for negative gearing even after July 2027?
Answer: Yes, eligible new builds retain full negative gearing indefinitely. New investors can still offset rental losses against all income, including salary, when purchasing a qualifying new residential property. The definition of ‘new build’ is based on whether the property was previously sold and genuinely adds to the housing supply.
FAQ: How does this affect my borrowing capacity for an investment property?
Answer: For established properties purchased after budget night, some lenders are already removing the negative gearing tax benefit from serviceability calculations, which can reduce what you are assessed to afford. For new builds, this calculation is unchanged. OM Financials compares your options across 50+ lenders. Call Shyam or visit omfinancials.com.au to understand your position.
The Decision Has Changed: Make Sure Your Finance Has Too
Before the 2026 Federal Budget, the choice between a new build and an established investment property was largely about yield, depreciation, and capital growth expectations. Those factors still matter. But the tax position and how lenders are treating it have now shifted materially in favour of new construction. For investors making acquisition decisions in the coming weeks and months, understanding the lending implications is as important as understanding the tax ones.
