You are under no obligation to accept the offer for the home that you listed where the listing expired. However, since the offers came to you before the listing expired, most likely you would be responsible for real estate commissions if you accept one or the other.Given the fact that the real estate agent (listing) that you had does not seem to want to assist you on these offers that came in before the expired listing, I suggest that you consult with a real estate attorney to counter any of the offers to possibly sell your home. If you close escrow, then you can deal with the real estate commission issue of your former listing brokerage later. It seems that the best thing for you to do is to close escrow on the property you are writing about for an amount you can live with.
