I have a couple of questions for the question. First, why is this question still around after almost 2 years of being posted? Second, why is James Graham's snotty answer the best one? How flip can one be?
The questioners problem is one faced by so many people today. As some have said, the best thing to do is to find a local Realtor who has local knowledge and one in whom you can have trust. Preferably, he or she will be one of considerable experience with the client's best interests at heart.
Are you considering to sell to buy? If so are you buying up or down and will you buy in the same market area? Do you have any equity? What are your financial circumstances and credit score? If you have been in your house for some time and didn't use it as an ATM, you may still have equity even though you likely can't get for it today what you could have gotten in 2006 or 7.
With positive answers to these questions and sufficient motivation, this could be an ideal time for you to make your move. Why? Low prices and interest rates. As a broker since 1980, I have never seen rates this low. Your purchasing power has probably never been so good. With a monthly payment of $2,000, your purchasing power went up by about $50,000 when you compare a 6% rate to 4.875%. Putting it a different way, if you make a lateral move in terms of loan amount, at $350,000 your monthly payment will be reduced by over $200 per month.
The question is one of many facets and cannot be addressed in a brief way - too many considerations. Too many of the answers here are shallow and meaningless. Find a Realtor you can trust and get it done.
