I'm sorry for your loss. I'm going to suggest you get advice from a variety of sources. As Real Estate agents, our general advice is to sell. This is how we make our living and for many people it is the best advice. For your situation it may be, but you should hear other voices that have nothing to gain from your decision.
Family, attorneys or wise friends may help you walk through the various decisions you need to make. If you do decide to sell, interview a few agents and find the one who has current success in this market and listens to you needs. This one may not suggest the highest price, and that may be the best advice.
