This is a tough one to call.

For any long enough time line, house prices are going to drop 80-99%.

But, as soon as states start opening up we will probably see a flurry of home sales as people cooped up finally get out to getting their dream home.

In other news, many small rental companies are going to go bust as people haven't paid their rent and the mortgages are due. So, these homes are going to be liquidated. And it all depends on when they come on the market.

Further, we will see a lot of small banks die from lack of mortgage payments
which will shut down some bigger banks, which will...

So, mortgages are going to become scarce.

Lastly, we are going to see lots of people moving out of the (soon to be) frozen north.
Driving down home prices there, and adding to the buyers in lower latitude housing markets.

All of these are almost guaranteed, but when, and in what order?
