not any time soon - to much of the economy is tied up in housing assets and we will likely see measures to keep prices growing even if slowly. Eventually it will get to a tipping point, but expect to see new house developments slow or grind to a halt, and schemes brought in to get people on the ladder at the bottom end to keep it moving. Schemes which wont lower the price, just spread the pain. Similar to the equity loan scheme the government did.
If the housing prices drop the conservatives are finished regardless of what peoples views on Starmer are as a credible alternative.
I dont think it will crash but it may slow down, however crashes are not good for people wanting to get on the ladder, as per the 2008 crash institutional investors hoover up property, and reduce overall stock which then drives the prices back up, but with lower stock of housing and more people trapped in rent.
