Practically all housing development is financed with borrowed money against the property. Given the build-to rent model, the party at the end of the cashflow stream relies on rent checks being paid every month to remain solvent. When the rents stop being collected, at some critical point, some loan that is reliant upon that rental stream will default. When that happens, the properties are called in by the borrower and auctioned off at foreclosure.

Now yes, the major lenders, developers and speculators will spread their risk as much as possible by diversifying their portfolios and try not to be caught short by a problem in any specific market. But when there is a some kind of macroeconomic shock, ALL the markets will suddenly contract and be flooded with foreclosed properties and other rapidly depreciating assets. That's more-or-less what happened in 2007. Massive liquidity injections and historically low interest rates supposedly saved us from a prolonged financial catastrophe then - but there were still a LOT of foreclosures. I also think we are still seeing that situation playing out today. Current housing markets are unsustainable in a climate of higher interest rates. This will all come crashing down, probably sooner than most people expect. When it happens, it happens fast - and of course the reasons will seem obvious with hindsight.

By the way, perhaps you're being ironic - "This time is different" is the defining catchphrase when looking at historical financial crashes: https://www.economist.com/media/pdf/this-time-is-different-reinhart-e.pdf

Yes, there is finite supply and ever-growing demand, however the price of real estate ultimately reflects both the buyer and lender's confidence that the mortgage payment will be met. This can be affected not only by interest rates but by labor market conditions and other factors.

If there is a sudden surge in interest rates in response to some kind of inflationary shock, or the credit market becomes suddenly much more restrictive in terms of lending standards, then housing prices will most certainly fall, simply because the pool of potential buyers at a given price level is smaller.

When pressures on the housing market are coupled with leveraged loans on variable rates going upside down, people will begin dumping their real estate investments. These factors compound to cause a sharp reduction in price. In 2007-8 metro home prices declined up to 50% from their earlier peaks - but seem to have increased about 200% since the bottom, roughly, to where they are today That's quite a considerable appreciation and seems unlikely to be sustained. Maybe I'm wrong - we're just shooting the shit on Lemmy - but looking at what's happened before, real estate seems overheated - but it may well keep on boiling for all I know.

It should be fucking illegal for corporations to own single-family homes, full stop.
