If you are a chart purist and want to see the numbers in raw spread sheet form, then after the jump are a few more nuggets of sales price information for April 2012. These ones are for the unwieldy suburbs and have all the usual categories for each county. Washington D.C. is in there just for comparison's sake, but all the deals are in Prince George's County. Their median sales price last month was under $200K.
