The average days on the market for the past 6 months is 81, assuming residential and not a short sale. The short is 0 and the long was 997. I had 185 sales come up in my quick search.
My advice is not to give too much credence to this information. Well presented, easy to show homes that are priced right will sell in 1-3 weeks. I you are on the market as a seller without an offer in that time as a seller, review your approach and make the necessary changes.
If you are a buyer and find the right home have your agent prepare a CMA and make the appropriate offer. Of those 185 sales, the average sell price compared to last list price is 99.07%. There are several at and over list price. Best of luck.
