Magdalena,

I am a mortgage broker. Trust me when I tell you... "cash Back" at closing more likely than not is illegal. If you don't like Prison. Stay away from that one.

Are you and Rcardo (selling his home in Spain) the same poster?

If structured properly, "cash out" to an investor is possible and perfectly legal. The structure itself is complex and varies state to state.
Please contact me with more information.

Not the place to list this type of "question" and, cash back at closing schemes are.....ILLEGAL 99.9% of the time. Cash back at closing schemes are being scrutinized by lenders and the federal government landing many participants in a heap of trouble. Ignorance of the law is no defence.
