I looked at the SMSF vs regular investors vs housing supply argument too broadly the first time. Here's the tighter version, and it makes the case even stronger. 📊🏗️
My first pass used Australia's total investor pool, 2.3 million people, and asked what a 5% shift would look like. Too broad. Most of those people already own what they own and aren't buying this year. So I went back and used the actual number of investors transacting annually instead.
Here's what that shows.
SMSFs are losing the ability to borrow for residential property from 10 August 2026. Real numbers range from 4,000 (the ATO's figure) to over 16,000 a year (industry lenders say the ATO is understating it).
But most of that SMSF lending was going into established homes anyway, not new builds. One major SMSF lender says only 1 in 5 of their SMSF loans funded new construction. Established homes don't add supply, they just change hands. So most of that "lost" activity was never adding to supply in the first place.
Meanwhile, every other investor in the country, all 2.3 million of them, just got a real reason to buy new instead of established, because that's the only way to keep full negative gearing going forward. And the number that matters here isn't the whole 2.3 million, it's the roughly 300,000 actually buying every year.
It takes about 1% of that pipeline switching to new builds to fully offset the entire SMSF supply loss. 5% dwarfs it five times over.
A small segment that mostly wasn't building anything is shrinking. A much bigger segment that actually builds things just got a reason to build more.
That's not a supply crisis. That's a supply shift. 🏡
