This graphs show the average days on market, which means the number of days from the date a property is listed, until the property goes Pending. It's good to note there are usually anywhere from a couple weeks to a couple months between the date a property goes Pending to the date the sale actually closes. The graphs also show the average difference between the listing price and the selling price of a property as a percentage of list price. So if the average is 90%, if a home is listed at $100,000 it will on average sell at $90,000.
Keep in mind that the better you price your home, the quicker it should sell. These days on market numbers are for the current listing only, and the selling price percentage is figured off of the last list price of the home...not the original list price.
