Buying an occupied foreclosure or REO

[Peter Pierzchala]

I'm seeing on some auction sites that a lot of the houses up for auction, either foreclosure or REO, the majority are listed as occupied. Do you just have to plan on evicting? What if there are tenants in place with a lease. Do you have to take over the property and wait for them to not pay you before you can start the process or are you able to start immediately?
