What Types of Properties Are Not Able to be Wholesaled?

[Juan Santiago]

I'm new to wholesaling, still in the learning process. I'm confused about what types of properties can not be used for a wholesale deal

I read in a book to only look for FSBO's, and not to look for bank owned properties. But what is a bank owned property? Is it someone that bought a house with a loan from the bank? Can I wholesale a property is someone still owes for the loan? I would really appreciate the help with these questions. Thank you.
