Last week, the Antiplanner posted a spreadsheet with metropolitan area home price indices and graphs. To complete the set, here is a similar spreadsheet for state. One difference is that the graph only shows inflation-adjusted indices, which are more useful anyway.
To graph different states, simply enter the two-letter abbreviation of up to six states (in caps) in cells BH167 through BM167. If you have autocalculation turned on, the graph should update automatically. If you want to change the years shown in the chart, click on the chart to select it, then scroll down to see the years selected (currently cells BG248 through BM329). Drag the upper right corner up or down to change the beginning year and the bottom right corner up to change the ending year. I hope you find these data useful.
