In the last downturn, Riverside’s median dropped over twice as much as San Diego’s. I think Riverside is going to be seriously crushed for those exact reasons you mention.
When I asked tenant attorney Steven Kellman in San Diego about foreclosure/eviction of a tenant, he said that if a bank takes over the house, they can kick me out. Unless the owner refinanced after the lease was signed so that the lease predates the refinance and the bank’s rights are secondary.
