Investor activity in Australian residential property is adjusting sharply in 2026 after a record run. Tax reform, three Reserve Bank rate rises and rising holding costs have combined to pressure returns. A live sector poll of more than 500 professionals found three-quarters expect a significant number of investors to sell up or stop investing, and 78% expect the reforms to push property values down. Fewer than one in 10 respondents believe the changes will improve housing supply. The view among professionals who advise, finance, value and regulate property transactions is that the reforms will reduce investor participation without lifting housing supply. Brokers are now central to how investors respond.
Investor lending hit record levels through 2025, accounting for more than 40% of all new home lending in the September and December quarters. The investor segment grew 18.9% year on year, outpacing owner-occupier growth of 12.5%. Conditions have since shifted. ABS data shows the June 2026 quarter saw new investor loan commitments fall 8.6% in number and 10.2% in value compared to the March quarter. "The investor market is in a significant period of adjustment," says Anja Pannek, chief executive officer of the Mortgage and Finance Association of Australia. Twelve months ago there was strong momentum, she says, but investors are now taking a more measured approach. Baber Zaka, general manager of third-party banking at Commonwealth Bank, calls it "a healthy recalibration rather than a change in direction."
The negative gearing and CGT overhaul became law in late June 2026. From 1 July 2027, negative gearing on established residential properties purchased after 12 May 2026 will be restricted. Losses can no longer be offset against wages or salary, they carry forward against future residential property income only. New builds retain full entitlements. The existing 50% CGT discount will be replaced by cost-base indexation, with a minimum 30% tax on real capital gains for all assets except new builds. Pannek's concern sits with the cumulative effect. "We've consistently highlighted concerns about the cumulative impact of the reforms, including changes to negative gearing, capital gains tax and borrowing through self-managed super funds. Individually they may appear manageable, but together they have the potential to influence investor confidence and housing supply," she says.
After delivering three cuts through 2025, the Reserve Bank of Australia raised the cash rate three times in 2026, in February, March and May, bringing it to 4.35%. That reversed all of the previous year's relief. On an average loan of $736,000, each 25-basis-point increase adds roughly $120 a month to repayments. Three hikes add around $360 per month compared to the start of the year. "Today's investor market is more measured. Broker feedback indicates investors are spending more time researching opportunities, assessing cash flow and seeking advice before making decisions," says Zaka. He adds that investors are placing greater emphasis on portfolio resilience and long-term objectives rather than simply responding to a fast-moving market.
For most capital city investors, the answer is no. Cotality data shows national gross rental yields recovered to 3.7% in July 2026, the highest since April 2023. Typical variable mortgage rates sit around 6%. Sydney gross yields are the lowest among capital cities at 3.3%. Holding costs add to the gap. Australian home insurance premiums have risen 51% in five years, according to data analytics firm Finity. The average home and contents policy rose 14% in 2025 alone, from $2,452 to $2,795 nationally. "Investors are spending more time understanding how an investment will perform over the long term. That includes rental yield, cash flow, long-term-growth potential and how the lending side of the equation works," says Sergio Delvescovo, national sales manager and broker at ING Australia.
The negative gearing restriction applies to residential property only. Commercial property retains full negative gearing under the new law. The market has moved quickly to price that distinction in. Industrial property recorded yield compression across every capital city in Q1 2026 and over the year to March. E-commerce growth, tight land supply and warehouse demand supported the trend. Some brokers are already seeing a 'tsunami' of investor interest in commercial following the tax changes. Brokers write a record 81% of residential home loans, according to MFAA data, yet commercial penetration remains far lower. "We're already seeing growing interest in commercial lending, and I think that trend is likely to continue. For brokers, that's a real opportunity to broaden the services they provide to clients," says Pannek.
APRA activated its debt-to-income cap in February 2026. The cap limits authorised deposit-taking institutions to writing no more than 20% of new residential mortgages at a DTI of six or above, with investor and owner-occupier portfolios assessed separately. The cap does not apply to non-bank lenders. That distinction shapes where investor business flows. Zaka says the measures have increased the focus on borrowing capacity and serviceability earlier in the customer journey. "The real winner is the consumer because mortgage and finance brokers have access to both markets," says Pannek. For investors whose borrowing sits at higher DTI levels, non-bank lenders remain a viable path that brokers with access to both channels are well placed to navigate.
Prices have cooled from their recent peak. Cotality's national Home Value Index fell 0.4% in June and 0.7% in July 2026, the steepest monthly drops since December 2022. Sydney and Melbourne year-on-year figures are now negative at -2.0% and -2.8% respectively. Auction clearance rates fell below 50% in late June for the first time since the 2020 lockdowns. Ray White data shows the investor share of auction buyers dropped to as low as 20.7% in late June. The investor credit growth outlook in 2027 is expected to drop by half from 2026. "Australia continues to face housing supply constraints, with population and strong rental demand in many areas. Those fundamentals continue to support long-term investor interest in residential property," says Delvescovo.
