Southern California home prices hold steady in August, sales hit high Southern California home prices remained flat in August from a month earlier and sales hit a seven-year high for the month as more homes went on the market. The median sales price was $385,000 last month in the six-county Southland, unchanged from July and June, real estate firm DataQuick reported Thursday. Prices were 24.6% higher than last year. In Los Angeles County, the median price rose 28.1% to $429,000 in August, while the median in Orange County was $560,000, 25.8% more than last year. PHOTOS: Most affordable SoCal ZIP codes for home buyers Home values have shot up sharply this year as traditional home buyers rushed into the market eyeing historically low mortgage rates amid an improving economy, but found few homes available for sale and significant competition from cash-carrying investors. Buyers purchased a total of 23,057 new and resale houses and condos in the Southland last month. That was 2.8% more than August 2012, but down 0.8% from July. This year's sharp price gains, as well as recent mortgage rate increases, have eaten away at affordability and frustrated many would-be home shoppers, while raising questions of how long the fervid pace can continue. But the steady median price figure over the last two months could signal that dramatic price increases are easing as more homes come on the market. "Home shoppers have more properties to choose as we begin to see a "supply response" to higher values," DataQuick President John Walsh said in a statement. Price pressures appear to be easing, though, amid higher mortgage rates, more supply and fewer cash and investor purchases.
