Our MLS in Suburban Philadelphia(TREND) just implemented a policy that exposes the DOM game. Say hello to PMP.

Days on Market, or DOM, refers to the number of days a listing has been on the market under a specific MLS number.

Property Marketing Period, or PMP, is the sum of Days on Market for multiple listings of one property

PMP is calculated differently than DOM. For example, MLS #1234567 is listed for 10 days, withdrawn for 5 days then put back on the market as MLS #7654321 for 10 days before selling. The PMP is 20 days, while the DOM is 10 days for each MLS number. The difference is that the PMP counts the days from both MLS numbers.

I think a selling agent today has the most unenviable job in the world, trying to explain to a nice family why their house is worth $100,000 less than they thought. Then compromising on price and spending money marketing the now overpriced house while it sits and sits and sits.
