Both evictions and foreclosures will take 1-2 years to get through. And thats if both happen at a mass scale. Which I dont think will happen. My guess is that 60-70% of people going to be evicted will just leave before anything gets filed. Banks will do pretty much anything to make sure someone doesnt go into foreclosure. So I don't think there will be a flood of those either. Even if theres 500k foreclosures, just because of the amount of time it take for them to process, they will trickle in over the next couple years.
The Fed has already laid the ground work for rising interest rates. They have to. Otherwise inflation will get to 10-15% and that will surely cause a crash. They would rather cause a big correction than a crash. So I think we will see interest rates in the 4-5% by winter, at the latest spring 22. This will be the tipping point in the housing market that will see a hard softening of prices dropping to more normal levels, so probably a 5-10% drop in price. What could spook the housing market to fall further than that, to the 10-15% range (maybe 20%), is if the stock market starts a major dip at the same time. Not because one controls the other, but because of humans being human and forcing a correlation between the two because thats what happened in '08. But I think that would be short lived with a quick rebound once everyone realizes it was an over reaction. Disclaimer - I don't have stocks (outside my 401k) and know very little about the stock market. So the stock market correlation is truly a guess on my part and not backed on experience or numbers.
What actually concerns me the most is the banks. They are already tightening up their lending requirements LIKE CRAZY!!! To the extent that a lot of people that bought a house 6-12 months ago would struggle to get approved today. I've been seeing a good chunk of the houses that come back on market because the buyer couldn't get approved. Not because they were way out of their lane and trying to buy a house they truly couldnt afford but because banks have raised the bar really high for buying standards now. My take on this is that they think another major crash is coming and are hedging against it since they see so many houses going for 10-20% above asking, even in this high peak market. I think they are wrong on a major crash but what I see as a potential consequence of this is that they are tightening up now bracing for a crash and when any dip in the market actually does happen (even if its only 5% dip) they will tighten up even further. Restricting the market to only top tier buyers with either lots of cash for a 30%+ down payment and/or those with very high credit scores (750+). This will get even more restrictive for non-owner occupied SF and MF 1-4 units. I'ver personally seen this already.
I also see rental demand spiking while, whatever ends up happening, happens. The next 1-2 years will see 10-20% increase in rental price yoy. Between a small dip in home prices, banks tightening lending requirements, tenants leaving before being evicted, and eviction and foreclosures eventually rolling out after year 1. It will drop back down around year 3-4 if everything takes a normal course back to "normal" price as if we had gain the average 3-5% yoy. So if anyone is going to buy in the next couple year make sure to run numbers on a "normal" rent price and make sure thing work at that price because I don't see these high rents staying with us past the next couple years.
Of course, I could be completely wrong. A famous politician once said "Don't under estimate a politicians ability to screw things up!" (I paraphrased of course)
