re: Backing out of Purchase Agreement

You can be as hard-headed as you want but you cannot make someone buy a house they don't want. Something turned them off, and it's a big decision/purchase to make. You are also not getting $30k from them, you are going to try and fight an uphill battle that will cost you more money in the long run.

My advice to you would be contact the party involved personally, have a conversation with them and move on. Honestly you don't even have to contact them, just move on. For the life of me, I'm not sure why you have such a short period of notice (10 days). It really sounds like you were out to take advantage of someone.
