The National Association of Homebuilders evaluate the reports for each major metropolitan area and then deems a given one "improving" if two conditions are met. First, all three data series must indicate growth in the current month and, second, at least 6 months have passed since each of the data points' respective "bottoms". The IMI ignore short-term spurts, in other words, and attempts to identify those areas showing long-term, sustainable growth. For relocating home buyers, "improving" cities may also offer better long-term employment and income opportunities. 33 states are represented in the September Improving Market Index, as well as the District of Columbia. 31 new areas were added to the list as compared to August and just 12 dropped off. The newly-added areas include Sacramento, California; Jacksonville, Florida; and Waco, Texas. Cities falling off the list for September include Dover, Delaware. The complete Improving Markets Index is available for download at the NAHB website. For a better gauge of what's happening in Bethesda on a local level, however, talk to a local real estate agent.
