ROCKVILLE, Md., Nov. 10, 2010 -- RealEstate Business Intelligence (RBI), an MRIS company, released the latest market data on the Washington, DC, Baltimore metro housing market today, which suggests that home prices in the market continue to remain stable, but the number of home sales remains lower than October 2009. This is attributable to the federal tax credit expiration, which offered an $8,000 tax credit for first-time home buyers and a $6,500 tax credit for repeat home buyers, who signed a purchase contract before April 30th of this year.
