Believe it or not, the District finally completed loading sales it recorded in February 2007, just in time for the Memorial Day holiday. At least I hope that's true; I've encountered instances when sales data was loaded months after the fact.
I've cleaned the data - a never-ending story - and geocoded it. No $88MM condos this time. It's now available on DCHomePrices.com and DCCondoPrices.com. I'll publish the sales analysis tomorrow.
