The mathematical average isn't very useful to describe how quick any particular property may sell. It depends a lot on where it is, the demand for that type of property, and most importantly, price. If you are thinking about selling a home, you can email me the address and your contact info and I can prepare a report for you that will show the competition for sale, what has sold, and days on market for homes like yours in your neighborhood.
