The San Diego economic forecast for residential real estate indicates that home prices have become more affordable, with 48% of households able to buy the median-priced home, despite rising interest rates and the expiration of government tax credits. Home sales, particularly for new builds, have rebounded due to incentives, although sales of existing homes have fallen since the fourth quarter of 2009 despite a price increase. The overall housing market remains fragile, influenced by economic conditions and a continuing shadow supply of foreclosures.
