Qualifying for a foreclosure, "repo," "REO," "Bank-owned" home is no different than qualifying for a regular home. As Marla mentioned, banks don't care what kind of purchase it is, though they do care about conditions about specific things within the home.
It's best if you ask for a list of homes available from your agent. Your agent can also enter your info where you will receive automatic updates on homes that come available on the market as soon as they are made available. It's possible this way that you see them even before your agent sees them at times, if you view your e-mail before he or she does.
If you are driving around and finding properties on your own it is best that you write those addresses down and give them to your agent to have him or her investigate those addresses and availability for them.
Good luck, Theresa.
