Sales Price / List Price Ratio
The sales price/list price ratio is the average sale price divided by the average list price for sold properties expressed as a percentage. If it is above 100%, homes are selling for more than the list price. If it is less than 100%, homes are selling for less than the list price. The September 2026 sales price/list price ratio was 104.67%, down from 107.52% from the previous month and down from 105.74% from September 2025.

Average Days on Market
