Thanks again to Jan-Martin for picking up this one. We at Doom were stunned when we saw this 12 minute video [1] about the Billings Montana housing market. There is really excellent use of footage of the houses, Geographical Info System (GIS) style maps placing the houses in context, and charts detailing trends in affordability, cash flow, inventory and much more. Kudos to blogger Doug Armknecht. More info on this Montana bubble blogger is here.[2]
