If my son's home is in pre-foreclosure in Florida, can I make a cash offer to the bank to buy it for a drastically-reduced price, with the intention of selling it back to him privately, or even rent-to-own it back to him? I've heard it may be unlawful for him to reside there after the foreclosure and sale, does anyone know if this is true? It seems it may be an easy way to eliminate over 100K from his current mortgage for the same house. Is this against the law?
