Prior to 2006, San Diego experienced a dramatic growth of real estate prices, to the extent that the situation was sometimes described as a "housing affordability crisis". Median house prices more than tripled between 1998 and 2007. According to the California Association of Realtors, in May 2007, a median house in San Diego cost $612,370. Growth of real estate prices has not been accompanied by comparable growth of household incomes: Housing Affordability Index (percentage of households that can afford to buy a median-priced house) fell below 20% in early 2000s. The San Diego metropolitan area had the second worst median multiple (ratio of median house price to median household income) of all metropolitan areas in the United States. As a consequence, San Diego had experienced negative net migration since 2004, with significant numbers of people moving to Baja California and Riverside county, with many residents commuting daily from Tijuana, Temecula, and Murrieta, to their jobs in San Diego. Others are leaving the state altogether and moving to more affordable regions
