The new federal budget might not be legislated yet, but the regulatory environment has changed, and most investors are not pricing that in. Bank policy has quietly been updating in the background. Annual credit growth for investor home lending is tracking at its fastest rate since 2015, which is exactly why APRA has moved. From 1 February 2026, a 20% cap on new loans with a debt to income ratio at or above six times came into force. That is not background noise. It is a direct constraint on the high leverage strategies that have driven investor returns this cycle.
Investor lending now accounts for 39.7% of all new mortgage lending, well above the decade average of 33.5%. That concentration tells you two things. First, competition for investment grade stock is intense. Second, APRA is watching, and a credit growth speed limit is not off the table if that share climbs further.
The affordability picture is becoming a structural issue for capital growth, not just a social one. The national dwelling value to income ratio has reached 8.2, and it is taking a median household approximately 11 years to save a 20% deposit. Only 14% of median income households can currently afford to buy the median priced home nationally, down from 43% just three years ago. A shrinking buyer pool is a ceiling on price growth, not just an equity story.
Adelaide is the city I think is most underappreciated in the current environment. It is delivering double digit annual growth at 11.4% alongside a 4.3% gross yield, a combination that is extremely difficult to find in a rising rate environment. Most investors are still anchored to Sydney and Melbourne out of habit. The data does not support that habit right now.
On the supply side, there is one number that should give investors more confidence than almost anything else. Total advertised listings nationally remain 15.1% below the five year average, and in Perth, new listings are 29% below year-ago levels. Demand is softening at the margins, but supply is not responding. That structural floor is what separates this slowdown from a genuine correction.
Rental growth at 5.7% annually is running at roughly 1.7 times the wage price index of 3.4%. For buy and hold investors, that is the most important defensive signal in the current data. The investors who do well from here are not the ones picking the hottest city. They are the ones who have modelled their cash flow at 4.6%, understand which segment of the market APRA's new rules are compressing, and are buying below the DTI threshold that triggers a lending restriction. Boring, disciplined, and solvent beats exciting and overleveraged every single time in a tightening cycle.
"The secret of getting ahead is getting started. The secret of getting started is breaking your complex, overwhelming tasks into small manageable tasks, and then starting on the first one."— Mark Twain
