I have heard people predicting a collapse of the housing market for almost a decade. I expect some areas will see a rise in prices, and some a fall.

Mass unemployment will cause problems for many, but at the same time lots of countries are essentially forbidding evictions and that has to have a somewhat balancing action for the short-term. How well that will hold up is an open question, and nobody knows the answer.

We are preparing to sell our current house and buy a new one. Our realtor (so grain of salt here) said that its currently a buyers market and that he expects it to remain that way at least through fall. But honestly, no one knows and there is no way to know.

Not necessarily. People are still buying houses. Interest rates are low.
