Actually if you think about it, one of the biggest gripes are from people who get irritated about listings that expire or cancel and then relist simply to have a lower DOM.
Wouldn’t this serve to eliminate that?
Also you can still get DOM by simply asking your agent to get a listing history report. This makes common sense even with DOM available as you can see when price changes were made, comments in fields, and ANY other changes such as if the home was in then out of escrow.
