Key Takeaways
- Qualifying established residential investment properties held, or under contract, before 7:30pm AEST on 12 May 2026 are grandfathered under the negative gearing reforms.
- The reforms became law on 26 June 2026 and are scheduled to apply from 1 July 2027.
- Refinancing a grandfathered investment property does not ordinarily remove its grandfathered status solely because the lender changes, although loan purpose, ownership arrangements and lender assessment criteria still need to be considered.
- Decisions about selling, refinancing or purchasing another investment property may involve both tax implications and lending considerations.
- Understanding how the negative gearing changes interact with borrowing capacity, serviceability and long-term investment goals may help investors make more considered decisions.
The recent negative gearing changes for investors have prompted existing property owners to reassess their position. While much of the public discussion has focused on future buyers, current investors are often asking a different question: what happens to the investment property I already own, and how does grandfathering negative gearing apply?
The reforms became law on 26 June 2026 and are scheduled to apply from 1 July 2027. For many investors, the effect will depend on whether their property qualifies for grandfathering under the transitional provisions. Although tax outcomes are only one part of an investment decision, understanding how grandfathering works may help when considering refinancing, purchasing another investment property or reviewing a long-term strategy. Working with experienced mortgage brokers in Sydney may also help investors understand how lender policies, borrowing capacity and loan structures interact with broader property goals.
This article explains what grandfathering means, how it applies to qualifying existing residential investment properties and why lending considerations remain just as important as tax rules. It also explores practical scenarios that investors may encounter while highlighting areas where professional tax, legal and lending advice may be appropriate.
What Does Grandfathering Mean Under the Negative Gearing Changes?
Grandfathering is a legislative approach commonly used when governments introduce significant policy changes. Rather than applying new rules to every existing arrangement immediately, grandfathering may allow qualifying arrangements already in place to continue under the previous rules while the new rules apply to later transactions.
In the context of the legislated negative gearing changes for investors, grandfathering protects qualifying established residential investment properties held at 7:30pm AEST on 12 May 2026 from the new negative gearing restrictions. The protection may also extend to a property where the owner had entered into a contract to acquire it before that cut-off, even if settlement occurred later.
A qualifying grandfathered property may continue under the previous negative gearing arrangements while the owner retains it, subject to the legislation. However, a later sale, transfer or change in ownership may affect whether the protection continues, so investors should obtain qualified tax and legal advice before changing the ownership structure of a property.
This approach can reduce disruption for current owners while allowing the Government to apply the new rules to later residential property acquisitions. Similar transitional arrangements have previously been used across Australia’s taxation and superannuation systems.
Why Grandfathering Matters for Existing Investors
For many property owners, negative gearing forms only one component of a broader investment strategy. Rental demand, cash flow, financing costs, long-term capital growth expectations and personal financial objectives may all influence investment decisions.
If an existing investment property qualifies for grandfathering, the owner can generally continue to apply the previous negative gearing treatment to that property after 1 July 2027. Later purchases may be subject to different rules, depending on whether the acquired property is a qualifying new residential build or an established residential property.
This distinction may become important when reviewing an investment portfolio or considering future acquisitions. An investor could hold one grandfathered property while another property purchased after the Budget-night cut-off is subject to the new arrangements.
It is equally important to remember that the negative gearing changes relate to taxation rather than lending approval. Banks and other lenders assess applications using their own credit policies, serviceability models and risk assessments regardless of whether an investment property is grandfathered.
Understanding the Difference Between Tax Rules and Lending Rules
Many investors understandably assume that tax changes automatically affect their home loan. In practice, tax legislation and lender policy are separate frameworks, although the tax treatment of an investment may form part of a lender’s overall assessment.
A lender primarily considers whether a borrower demonstrates sufficient capacity to meet ongoing repayments under its lending policy. Tax treatment may influence an applicant’s overall financial position, but it is only one factor within a broader credit and serviceability assessment.
Serviceability Assessment
When assessing an investment loan, lenders generally calculate whether repayments remain affordable using serviceability models. These calculations commonly consider:
- Employment income and its stability
- Rental income, often after applying lender-specific shading policies
- Existing debts and repayment commitments
- Living expenses
- Interest rate buffers required under current lending policy
- The borrower’s total debt relative to income
Although the Australian Prudential Regulation Authority (APRA) sets prudential requirements and expectations for authorised deposit-taking institutions, individual lenders retain flexibility in how they assess applications within those regulatory settings. As a result, borrowing capacity may vary between lenders even where the borrower has identical financial circumstances.
From 1 February 2026, APRA also limits the proportion of new residential mortgage lending that authorised deposit-taking institutions can provide at a debt-to-income ratio of six times income or more. The 20% limit applies separately to new investor lending and new owner-occupier lending. It does not prohibit every loan at or above that level, but it may affect the availability of highly leveraged lending.
Income Shading
Rental income may not always be assessed at 100% of the amount received. Many lenders apply income shading to allow for vacancies, property expenses and other investment risks. Some lenders may also assess overtime, bonuses, commissions or self-employed income differently depending on the consistency, history and reliability of the income source.
This means two lenders could reach different borrowing outcomes despite reviewing the same financial information.
Property Security
Lenders also evaluate the property being offered as security. Loan-to-value ratio (LVR), property type, location, condition and marketability may all influence available lending options. These considerations remain separate from whether a property’s tax treatment has been grandfathered.
Can You Refinance a Grandfathered Investment Property?
One of the most common questions existing investors ask is whether refinancing affects grandfathering.
Refinancing a qualifying investment property does not ordinarily remove its grandfathered status solely because the owner changes lenders. The grandfathering provisions generally relate to the qualifying property and its ownership rather than the identity of the lender providing the finance.
However, investors should distinguish between refinancing the existing investment debt and increasing or restructuring the loan for another purpose. The tax deductibility of interest generally depends on how the borrowed funds are used, not only on the property securing the loan. For example, additional funds used for private expenses may not be deductible merely because the borrowing is secured against a grandfathered investment property.
Changes to the ownership of the property, transfers between entities or more complex loan restructures may also have separate tax and legal consequences. Qualified advice should therefore be obtained before making material changes to the property ownership or debt structure.
Refinancing may be considered for many reasons unrelated to taxation. Some borrowers review their loan when interest rates change, fixed-rate periods expire or existing loan features no longer suit their circumstances.
Investors considering these options may also find it helpful to understand broader refinancing investment property strategies, particularly where lending decisions, the purpose of borrowed funds and potential tax implications intersect.
Refinancing typically requires a new credit assessment. Approval depends on the borrower’s current circumstances and the new lender’s credit policy rather than the terms under which the original loan was approved.
Situations Where Existing Investors May Review Their Loan
There is rarely a single reason for reviewing an investment loan. Instead, several financial or lending factors may prompt borrowers to reassess whether their existing loan structure continues to meet their objectives.
Interest Rates Have Changed
Changes in interest rates may alter monthly repayments and long-term borrowing costs. Some borrowers review available loan products after interest rate movements to determine whether a different rate, repayment structure or loan feature could better suit their circumstances.
Cash Flow Has Changed
Rental income, employment income or household expenses may change over time. These changes could influence whether an existing repayment structure remains manageable or appropriate.
Portfolio Growth
Some investors consider purchasing another property after building equity in an existing investment. Understanding available investment property loan options may help when evaluating borrowing capacity across multiple lenders, particularly where servicing calculations and debt-to-income policies differ between institutions.
How Future Investment Property Purchases Will Be Different
While grandfathering preserves the treatment of qualifying existing properties, later residential investment purchases may be subject to different negative gearing rules from 1 July 2027. Investors may therefore need to evaluate each property separately rather than assuming the same tax treatment applies across an entire portfolio.
Under the legislated federal budget changes for investors, full negative gearing for residential property acquired after the Budget-night cut-off will generally be limited to qualifying new residential builds. This means losses associated with an eligible new build may continue to be deducted against other assessable income, subject to the ordinary tax rules.
For an established residential property acquired after 7:30pm AEST on 12 May 2026, rental deductions that exceed residential rental income will generally no longer be available to offset unrelated income, such as salary or wages, from 1 July 2027. Restricted losses may instead be carried forward and applied in accordance with the new rules.
Under the legislation, the reforms generally limit full new build negative gearing treatment to qualifying new residential properties, with the stated aim of directing investment towards additional housing supply. Investors purchasing established residential properties may face different tax outcomes from investors purchasing qualifying new build properties.
Tax treatment should not be the sole basis for a property decision. Property value, location, rental demand, financing costs, cash flow, ownership structure and the investor’s personal circumstances may all affect whether a purchase is suitable.
Common Scenarios Existing Investors May Face
Every investor’s circumstances differ. The following examples illustrate how grandfathering and lending considerations may interact in practice. They are simplified examples only and do not represent tax, financial or legal advice.
Scenario 1: Refinancing an Existing Investment Property
Emma purchased an investment property several years ago and held it before 7:30pm AEST on 12 May 2026. She is reviewing her loan after her fixed interest rate expires. Although the property qualifies for grandfathering, she still needs to satisfy the new lender’s serviceability and credit assessment. Her borrowing capacity depends on her current income, existing debts, living expenses, total debt-to-income position and the lender’s assessment policies rather than the age of the investment property alone.
If Emma only refinances the existing investment debt, changing lenders would not ordinarily remove the property’s grandfathered status. However, if she increases the loan for private spending, the tax treatment of interest on the additional amount may differ because deductibility generally depends on the use of those funds.
Scenario 2: Purchasing an Additional Investment Property
Michael owns one grandfathered investment property and is considering buying another. His existing property can generally continue under the previous negative gearing rules while he retains it. The second purchase may fall under the new framework from 1 July 2027, depending on when it was acquired and whether it is a qualifying new residential build or an established property.
Michael therefore reviews both the taxation implications and his borrowing capacity before proceeding. He also considers how the additional debt may be assessed under lender serviceability requirements and current debt-to-income policies.
Scenario 3: Restructuring an Investment Portfolio
A couple nearing retirement decides to review several investment properties held over many years. Rather than focusing only on grandfathering and potential tax treatment, they also consider loan repayments, future income needs, property performance and overall financial objectives before deciding whether selling, refinancing or retaining each property may be appropriate.
Because transferring or selling a qualifying property may affect its grandfathered treatment and create other tax consequences, they obtain qualified tax and legal advice before making changes to ownership or disposing of an asset.
Common Misunderstandings About Grandfathering
Media coverage of investment property changes can sometimes create confusion. Understanding a few common misconceptions may help investors ask more useful questions when reviewing their position.
Grandfathering Does Not Automatically Increase Borrowing Capacity
Although maintaining the previous tax treatment may influence an investor’s overall financial position, lenders still apply their normal credit assessment processes. Borrowing capacity continues to depend on income, liabilities, living expenses, interest rate assumptions, debt-to-income position, lender policy and servicing calculations.
Refinancing Is Not Automatically Prohibited
Refinancing alone does not ordinarily remove the grandfathered status of a qualifying property solely because the lender changes. However, every refinance application is assessed under current lending criteria, and approval is not automatic.
The purpose of any refinanced or additional borrowing should also be considered. Interest deductibility generally follows the use of the borrowed funds, while a transfer or change in ownership may have separate consequences for the property’s grandfathered treatment.
Buying Before 1 July 2027 Does Not Automatically Secure the Previous Rules
The relevant grandfathering cut-off was 7:30pm AEST on 12 May 2026, not the 1 July 2027 commencement date. An established residential property acquired after the Budget-night cut-off will generally be subject to the new negative gearing restrictions from 1 July 2027, even if the purchase is completed before that commencement date.
Tax Outcomes Are Only One Part of the Decision
Investment decisions often involve multiple considerations beyond taxation. Interest rates, loan features, cash flow, property performance, long-term objectives, ownership structures and changing personal circumstances may all influence an appropriate course of action.
Why Professional Advice May Still Be Valuable
Tax legislation, lender policy and property markets continue to evolve over time. Even where the general rules appear straightforward, applying them to an individual situation can become more complex when multiple investment properties, trusts, companies, changing employment income, ownership transfers or refinancing strategies are involved.
A mortgage broker may assist by comparing lender policies, assessing borrowing capacity and explaining how different loan structures could operate under current lending guidelines. A broker cannot provide tax or legal advice unless separately qualified to do so.
Separately, a qualified tax adviser can explain how the current legislation applies to an investor’s circumstances, including whether a property qualifies for grandfathering and how the use of refinanced funds may affect interest deductibility. Legal advice may also be appropriate before changing a property’s ownership or transferring it between individuals or entities.

Conclusion
For many existing property owners, grandfathering provides continuity for qualifying established residential investment properties held, or under contract, before 7:30pm AEST on 12 May 2026. The negative gearing reforms became law on 26 June 2026 and are scheduled to apply from 1 July 2027.
Preserving the previous tax treatment is only one aspect of managing an investment portfolio. Refinancing decisions, borrowing capacity, lender assessment policies, debt-to-income requirements, property performance and long-term financial objectives may all remain important when reviewing future opportunities.
Because lending policies and tax rules can change and their application depends on individual circumstances, investors may benefit from considering tax, legal and finance implications together before making significant property or borrowing decisions.
This article contains general information only and does not constitute financial, tax or legal advice.

The negative gearing reforms discussed in this article became law on 26 June 2026 and are scheduled to apply from 1 July 2027. Investors should obtain qualified tax and legal advice about how the transitional provisions, grandfathering rules and interest deductibility requirements apply to their circumstances.
Frequently Asked Questions (FAQs)
1. What is grandfathering in relation to negative gearing?
Grandfathering refers to transitional rules that may allow qualifying established residential investment properties held at 7:30pm AEST on 12 May 2026 to continue under the previous negative gearing arrangements. The protection may also cover a property that was under contract before the cut-off but settled afterwards.
2. When do the negative gearing changes apply?
The reforms became law on 26 June 2026 and are scheduled to apply from 1 July 2027. However, the relevant cut-off for grandfathering is 7:30pm AEST on 12 May 2026.
3. Will refinancing affect my grandfathered investment property?
Changing lenders alone would not ordinarily affect the grandfathered status of a qualifying property. However, the tax treatment of refinanced or additional borrowings depends on how the funds are used, and changes to property ownership may have separate consequences. Investors should obtain qualified advice before restructuring debt or ownership arrangements.
4. Can lenders assess my application differently even if my property is grandfathered?
Yes. Lenders apply their own credit assessment policies when reviewing loan applications. Factors such as income, existing debts, living expenses, loan-to-value ratio, debt-to-income ratio and serviceability calculations may differ between lenders.
5. Will negative gearing changes apply to every investment property?
No. Qualifying established residential properties held, or under contract, before the Budget-night cut-off may qualify for grandfathering under the legislation. For later residential property acquisitions, full negative gearing may be limited under the legislation to qualifying new residential builds from 1 July 2027. Established residential properties acquired after the cut-off may be subject to the new restrictions.
6. Does buying before 1 July 2027 secure the previous negative gearing rules?
No. The grandfathering cut-off was 7:30pm AEST on 12 May 2026. An established residential property acquired after that cut-off may be subject to the new rules from 1 July 2027, even if the purchase occurs before the commencement date.
7. Should I sell my investment property before the changes commence?
There is no single answer that suits every investor. Decisions about selling may involve taxation, capital gains tax, lending, market conditions, cash flow, long-term objectives and personal circumstances. A qualified tax adviser, legal adviser and lending professional may help assess the relevant considerations.
8. Where can I find official information about negative gearing?
The Australian Taxation Office, Australian Government Budget website and Federal Register of Legislation publish official information about the reforms and their application. Investors should check current official guidance and obtain qualified advice regarding their circumstances.
