You will have to decide for yourself if I'm speaking from experience or have motivated reasoning, as I'm saying this as an overseas absentee landlord who bought a UK apartment around the tail end of the previous price crash, initially as a place to live in until I decided the UK wasn't for me any more, and was rich enough to do so without a mortgage.

(I left the UK in 2018 due to a mix of Brexit and technological incompetence in the form of the Investigatory Powers Act. Would have left UK sooner but for parent with Alzheimer's).

Reason being: the income from housing doesn't have to come from reselling houses (which a price crash would impact) — I'm collecting rent, not flipping property. Forecasts future increases to rental rates suggests it won't keep getting worse (relative to general inflation) than it already is for renters, but it's already obviously quite bad.

What is needed is a steady decrease in demand or an increase in supply.

The cost of living crisis is directly caused by the huge bureaucracy needed to build new housing. And speculators are benefiting from that. As long as governments are unwilling to let go of regulations housing costs will only increase.
