I crunched so many numbers, my teeth hurt.

There's lots to see besides the story:

--Maps (showing the change in metro-area sales and prices, and the same for city neighborhoods) by cartographer extraordinaire Christine Schoenberg, who gave up part of her vacation to pull everything together in time.

--A video about recent home buyer Will Cocks, who moved from Bowie to Baltimore. Thanks to multimedia whiz Christopher Assaf for piecing my raw footage into something watchable.

--A photo gallery showing the place Amy Lincoln MacDonald and Paul MacDonald sold in Glen Burnie and the one they bought in Lauraville, along with Cocks moving into his Greenmount West home. Photography by the excellent Kenneth K. Lam and Karl Merton Ferron.

--A nifty online search tool, put together by web guru Lauren Custer, that lets you see how many homes sold in your ZIP code, for how much and how trends changed from a year ago.

--An Excel file showing home-sale trends in city neighborhoods. In that file you'll find worksheets with the neighborhoods ordered alphabetically, by price change and by sales change. (There's also a clickable city map that lets you see which neighborhood is which, put together on short notice by the inestimable Kevin Richardson.)
