Asking Prices Lie: Sold Comps, Price Drops, and Days on Market

Every bad exit estimate starts the same way: open a listings site, look at what similar cars are listed for, and call the middle of that range "market value." The problem is structural — listings are a survey of seller hopes. The cars priced right leave quickly and stop being visible; the overpriced ones accumulate and dominate what you see. Averaging them builds optimism into your spread before you have bid a dollar.

Sold prices

What comparable cars actually transacted for is the only number that settles arguments. Where true sold data is available, weight it far above asking. Where it is not, the next two signals let you infer it.

Price drops

A listing's price history is a negotiation happening in public. A car listed high and cut twice is telling you where the market said no. Across many comparable listings, the pattern of cuts sketches the ceiling real buyers will pay — treat the post-drop prices as closer to truth than day-one asks.

Days on market

Velocity is the difference between a spread and a story. Two cars can share an exit value while one sells in a week and the other sits for two months — and every week of sitting is holding cost plus drift plus the growing likelihood of a price cut. When you estimate exit value, estimate time-to-sell beside it; a high exit that arrives slowly is frequently worth less than a modest exit that arrives fast.

The practical method

Build the exit from sold comps where you can get them. Where you cannot, use the post-drop asking prices of listings that then disappeared, and let stale, uncut listings define the ceiling you will not underwrite to. Then let local days-on-market set the holding estimate in your maximum-bid subtraction.

Sellers price cars with hope. Underwriting replaces hope with what the market has already demonstrated it will do — and walks into the lane knowing not just what the car is worth, but how long the money will take to come back.
