Single family home are poor long term investments for institutions, outside of maybe California. Prices tend to follow inflation while property taxes and maintenance eat growth. States without income taxes tends to make up revenue through higher property taxes.

Because of these facts, I don't see this trend of investors gobbling up SFHs to be sustainable. I suspect most of them are in this for a quick buck, and will quickly dump these homes the minute it becomes obvious that this was a dumb idea.
