In one line: How long a listing has been for sale, and the seller's patience meter.
Days on market counts how long a home has been listed for sale. It is the most-watched number in negotiation: a fresh listing's seller is testing the market, while one sitting at twice the area's median has usually started listening.
The number is routinely laundered. Delisting and relisting resets the counter on most portals, which is exactly why buyers should be suspicious of a suspiciously fresh listing in a slow market.
Kouzr counts DOM from its own daily snapshots, so a relist does not reset it, and listing pages show the ZIP's median alongside for scale.
A worked example
A home listed 74 days in a ZIP where the median is 41 has been passed over by most of the buyers who will see it. Its seller has either priced it wrong or is not in a hurry, and the price history says which.
Questions people ask
Does relisting reset days on market?
On most portals, yes: a home withdrawn and relisted starts at zero. Kouzr's own daily snapshots keep the first day it was seen, so a relist does not hide the history.
What is a normal number in Las Vegas?
It moves with the season and the market. The market reports carry the current median for each place and each ZIP, which is the only useful comparison.
