What is the best strategy? Im talking about buying or flipping REOs. When i mean buying a lot of you out there who are basically rehabbers and you want to buy properties, fix 'em up and sell 'em. Folks, the best deals that you gonna get are REOs and of course when i mean an REO is also mean a Bank Owned Property. There's a couple of people that asks a little about REOs. Basically an REO is when a homeowner fails to pay their mortgage payments the bank files what is called a Foreclosure suit.
