Example: A home was listed for 90 days and received no offers. The listing expired or the Seller removes the property from the market. Then the Seller re lists the property. The new listing will show the Average Days on the Market for the "run" as related to that particular listing period. However, the CDOM will report the cummulative days on the market counting the days listed not starting with the first day of listing regardless of the agent or brokerage offering the listing. This might read 2 days ADOM and 92 CDOM since the property was first listed.
Hope that this information helps.

CDOM = Cumulative Days on Market
In the past, it was possible to take the house off the Market (MLS Listing) for a day or two, then put it back on, and the days would go back to zero. So anyone looking, would think that it had just been listed. Get the picture?
It has nothing to do with Assessment.
Good luck and may God bless
