Houston home shoppers went on a buying spree in May, sending sales and pricing through the roof.

According to the Houston Association of Realtors, real estate agents sold 6,185 single-family homes last month, an increase of 23.8 percent over May 2011.

The median price for single-family home hit a record high, rising 7.1 percent over last year to $168,000.

Lower-priced foreclosures made up 17.8 percent of all property sales.

Job creation and low interest rates are driving the buying frenzy, according to the association's chairman.
