The May 2011 MLS statistics for the Houston real estate market will be released on Tuesday. The document discusses how the 2010 home buyer tax credit has distorted year-over-year comparisons of home sales and prices. While the average and median home prices in May 2011 were the highest for a May in Houston, home sales fell nearly 12% compared to May 2010 due to the tax credit's influence. The number of homes under contract, with closings expected in 30-60 days, rose over 35% year-over-year.
