Working on potentially our first investment deal and need some advice. My wife's grandmother owns a house outright. She is very ill and is currently in a nursing home. 2 of her sons who are in their 50's still live at home and feel They are the owners even tho Grandma is the ONLY one on title. We have approached them about buying their home cash so that proceeds can go and take care of grandma while she is STILL alive. I told my wife that probably the next step to take would be get ALL sibblings on board(and they are) and get together with the attorney. There are several sibblings but One seems to be a thorn and its one that still feels HE owns the house. We have been as nice as possible with him as we dont want this to get ugly..........Any advice on this would be great :)
