About this chart
This chart counts the listings under contract for single-family detached homes on ARMLS in one ZIP code: Pending listings plus UCB / CCBS listings. Each point is the reading on the 1st of the month. It shows how much buying activity is under way.
Each year has its own line, laid out by month, so you can compare this year with earlier years at the same point in the season. Pick any of 149 ZIP codes from the ZIP Code list (it opens on 85003); the last three years are ticked to start with, and you can tick any year back to 2011.
Hover over a line to see the exact figure for that month.
