I will ask you why you are asking.
Are you trying to make a determination for how long you home will be on the market. Homes either sell very quickly, or they tend to sit and possibly not sell.
My answer, it depends!
It depends on how serious you want to sell. If you are serious you will do the right things to make sure your home sells quickly. say 30 days.
2 things determine whether a buyer buys a home. Price and condition.
And of course finding a top Realtor is another part of the puzzle. It not only shows you are serious about selling a home, but you will get the counsel to make sure you get it right.
