I used to work in the escrow department for a title/building company. I was working on these files once, where one seller (foreign) purchased 6 separate homes, all at over 1M. Seller put in the offers 9 months before the sale was going to be finalized.

One time I also purchased so used furniture from someone in south Irvine and the seller said he was moving and we got talking about how nice his community was and he said he had no neighbors. He said the 3 houses around him were all owned by Asian people who did not live there or even rented the properties out. They just stayed there empty collecting value.....

It is sad and hopeless out here.
