房子在哪里 every state could be different

I only know California. If you already released inspection contingency and financing contingency, then be prepare to lose the deposit (up to a few percent of the total price forgot if it is 2 or 3 %).

If it is investment property as long as the deal make sense, I would say don't be too emotional. If you will live in there, then the question is do you want to live there or not. Don't tie it to the problem with your agent.

If you don't like the service of the buyer agent you can complaint and see if she will settle with you or risk getting something logged with the board.
