The Dow Jones Real-Estate Index also includes a Starter Home Index [WSJ].  The data comes from First American Realty Solutions which uses condo and single family sales. These towns have a median income of $40,000.
Webmaster’s note: The data set shows a 5.3% increase in the Upper East Side neighborhood of Manhattan, which is the lowest of the areas presented. Its interesting because they are missing about 2/3 of the housing stock for that market because they do not track co-op apartments.
