I am coming back to the USA on vacation for several weeks in the next few months. There is a condominium I am looking at buying. I assume that I wouldn't be able to close fast enough on the property before I have to go back. Due to tax laws, I can't stay in the country for very long. Also, it would be annoying and costly to fly back a 2nd time just to close on the property. So my question is: Do I need to be physically present to close on a property? Can they just Fedex me the necessary documents to sign?
