Landlords Offload Record Number of Rentals Ahead of Tax Reforms, Fueling Rental Market Squeeze

Australian investors have flooded the property market with thousands of former rental homes in recent months, driven by fears over impending federal tax changes. According to fresh analysis by property data firm FoundIt, landlords sold a record 22,640 ex-rental properties nationally between February and May 2026. In Sydney alone, 4,865 such homes hit the market, while Melbourne saw 5,565. That meant roughly 21 per cent of all homes listed for sale in both cities during the period were previously tenanted.The sell-off, described by FoundIt head of research Kent Larnder as a “flood,” hit hardest in low-yield inner-city pockets. Sydney’s CBD, inner south, north shore and Parramatta suburbs led the charge, with Parramatta alone losing 572 rental listings. In Melbourne, sales surged in Docklands, Southbank and western districts. Many of these properties were snapped up by owner-occupiers rather than new investors, effectively shrinking the private rental pool at a time when supply is already desperately tight.The timing is no coincidence. Ahead of Treasurer Jim Chalmers’ federal budget delivered on 12 May 2026, speculation swirled around wide-ranging reforms to negative gearing and the capital gains tax (CGT) discount. Investors worried that generous tax breaks—long criticised for inflating house prices—were about to be wound back. Marginal landlords, already squeezed by high interest rates, rising insurance costs and patchy rental yields in cities like Sydney, decided to cash out early rather than risk higher future tax bills. Some were simply locking in existing CGT discounts before any shift to an indexation system.The budget itself delivered a nuanced outcome. Existing landlords were largely spared: negative gearing arrangements for properties already owned remain fully grandfathered. However, from July 2027, new investors buying established homes will face restrictions, with full concessions limited to new-build dwellings. The 50 per cent CGT discount is also being replaced by a cost-base indexation model plus a 30 per cent minimum tax on gains, again applying prospectively. The government argues the changes will channel investor capital toward new housing construction—potentially adding tens of thousands of extra homes—while easing pressure on first-home buyers.Yet the short-term fallout is already visible. National rental vacancy rates hover around a critically low 1.0–1.2 per cent, with Sydney and Melbourne sitting near 1.1–1.5 per cent. Rents have climbed steadily through 2025–26, with annual growth hitting 5–8 per cent in some capitals and quarterly spikes even sharper in Perth and Brisbane. SQM Research director Louis Christopher has warned that further erosion of investor incentives could push Sydney and Melbourne rents up by as much as 20 per cent if supply doesn’t rebound quickly. Multi-property investor Nathan Birch, who holds around 350 homes, has been even blunter, suggesting many landlords will simply pass costs on through immediate rent hikes.Not everyone agrees the sky is falling. Some analysts point out that every ex-rental sold to an owner-occupier simply shifts a property from the rental stock to owner-occupation without reducing total housing supply. Victoria’s earlier negative-gearing tweaks did not trigger the predicted rent explosion, with growth actually slowing in Melbourne between 2023 and 2025. Mortgage broker Brett Sutton notes the uncomfortable reality: most tenants cannot afford to buy the homes being sold, so shrinking investor participation leaves renters with fewer options.Broader pressures continue to weigh on the market. Strong population growth from migration, sluggish new-home construction and elevated interest rates have kept the rental crisis simmering for years. While the budget’s focus on new builds may eventually ease the crunch, experts like buyer’s agent Michael Kowalczyk stress that only a genuine increase in overall housing supply—beyond tax tweaks—will deliver lasting relief for tenants. In the meantime, landlords are voting with their feet, and Australia’s already-stretched renters are feeling the pinch.
