I invested $40K in my relative's home. It was agreed that I would a.) receive money in event of sale or b.) inherit the house. They have decided to walk away and allow a foreclosure. I am not in a position to buy the house and property sales here are very slow so I can't sell to buy. Can I file a lien to get my money back? Is there an advantage if they quit claim the property deed to me? Can I use the lien as a down payment?
