Months of supply is the better way to think about pace than a days-on-market average. A lower number of months of supply means less competing inventory for buyers to choose from, which tends to shorten the path from listing to accepted offer for a well-priced house.
Condition and price relative to comparable sold homes matter more than the season. An overpriced house can sit for months in a fast market, while a well-priced, well-presented one can draw an offer quickly even when overall supply is looser.
The honest way to estimate your own timeline is a comparable-sale review of homes like yours, not a citywide average. Get your hand-reviewed valuation from Joel Dyck.
