They are not published on a schedule and they are not a monthly snapshot. Both towns are read from the live MLS feed at the same instant, when you open this page, so the two sides are always measured against each other rather than against different weeks.
Both sides of this comparison are recalculated from the live MLS feed at the moment the page loads - neither is a monthly snapshot, and the two are read at the same instant so they are always comparable. Figures cover residential homes for sale; rentals, land and commercial are excluded, as are fractional co-ownership shares, which are priced per share and would distort the medians. Sold figures cover the last twelve complete calendar months. Market data is deemed reliable but not guaranteed - talk to us before making a decision on it.
The listings these figures are drawn from were last changed at the MLS on September 22, 2026 at 9:20 PM Mountain time. The figures themselves are worked out again from scratch every time this page is opened.
