About this chart
This chart shows annual appreciation: how much prices have changed compared with the same point a year earlier, measured every week. The price compared is the median sales price over the last month (Based on Monthly Median Sale Price). Above zero, prices are higher than a year ago; below zero, they are lower.
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 2002 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, Transaction Type, and New / Resale boxes and the sales price, home size, and year built sliders. The Inflation (CPI) option compares prices in today’s dollars, using national or Phoenix inflation, so you can see appreciation after inflation.
