Crashing the economy is of course going to have knock on effects. I don't think anybody should be surprised by this?

Housing is essentially a bottomless pit when the economy is good, it can sink any amount of money because it is an absolute necessity. So when people have money they'll use it to bid against each other for a scarce resource. But when the economy pauses or even starts to shrink then that surplus evaporates and one of the first indicators that this is happening is the demand for housing. Usually the result will be some price adjustments and after that it is business as usual. But if the cuts go deeper then there may be more substantial effects.

The only thing that is holding the US economy afloat right now is the fact that there are still a couple of levers of power that Trump hasn't gotten his fingers on. When and if that happens I fully expect things to go into freefall.
