House insurance during eviction after REO purchase

I'm thinking of buying a REO that will require me to evict the previous homeowner. Once he's out, I plan on occupying the house as my primary residence. But in the intervening few months required to evict him, what kind of building insurance can I get to protect myself against fire, earthquakes...? This scenario doesn't seem to overlap with a) normal homeowner's insurance as I'm not living there yet b) landlord insurance (we don't have a contract) or c) flipper insurance (i'm not renovating an empty building.)

Any ideas?
