About this chart
This chart shows annual appreciation for single-family detached homes in one city, measured every week on Thursdays: the change in the average sales price per square foot over the last 12 months compared with the 12 months to the same date a year earlier. 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 Phoenix and the last five years. Pick any of the 34 cities (18 major and 16 secondary) from the City list, and tick any year back to 2002 in the Year panel.
