About this chart
This chart shows the year-over-year change in supply: the number of homes for sale on ARMLS each Saturday compared with the same week a year earlier, as a percentage. Above zero, there is more inventory than a year ago, which gives buyers more choice; below zero, less.
By default it counts Active and Coming Soon listings; tick UCB / CCBS (under contract but still accepting back-up offers) or Temp Off Market in the List Status panel to include them. It opens on the last four years; use the Period panel to show the last 2 or 8 years, everything since 2011, or chosen years.
It opens on the Greater Phoenix area: the counties, cities, and ZIP codes that make it up are ticked to start with. Tick or untick any of them to change the area, including counties beyond Greater Phoenix. Narrow it further 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.
