There are several key statistics that are used to determine the health of any real estate market – average days on market, month’s supply of inventory, sales absorption rate, and the median sales price. Days on market (DOM) describes how long a home is active on the market before its status changes to pending.  The average days on market is determined by adding each listing’s days on market in a month, then dividing by the number of active listings for sale at the end of that month.
