I have yet to have a property I couldn't keep tenants in for at least a decade. Some even sign 2+ year leases if they plan on being in the area for a while.
As long as the mortgage is covered, I can hold a property indefinitely.
2007-9 isn’t really comparable to what went down in the 90s, especially for californian real estate after the Japanese had to liquidate from their binge, but all throughout the country as well.
