About this chart
This chart counts the homes listed for sale on ARMLS, measured every week (on Saturdays).
By default it counts Active listings. Tick Coming Soon, UCB / CCBS (under contract but still accepting back-up offers), or Temp Off Market in the List Status panel to include them.
Each year has its own line, laid out by week of the year, so you can compare this year with earlier years at the same point in the season. It opens on the last three years; tick any year back to 2011 in the Year panel.
It opens on Maricopa and Pinal Counties with every city and ZIP code included. Use the County, City, and ZIP panels to focus on any area, from a whole county down to a single ZIP code. Narrow it with the Dwelling Type, List Status, Transaction Type, and New / Resale boxes and the list price, home size, year built, and days on market sliders.
Rising inventory gives buyers more choice and more negotiating power; falling inventory favors sellers. Hover over a line to see the exact figure for that week.
