Silicon Valley’s million-dollar home sales reached their highest level in three full years in June as the high-end market continued to bounce back from the recessionary downturn, according to a new market report by Coldwell Banker Residential Brokerage, the region’s leading provider of luxury real estate services. 

A total of 284 homes sold for more than $1 million in Santa Clara County last month, up from 230 sales in May and 266 in June 2010. The 284 transactions were the most million-dollar deals in the county for any month since June 2008, the period leading up to the Lehman Brothers collapse and the subsequent crash of the financial markets.

The median sale price of a million-dollar home in Silicon Valley also moved higher in June to $1.4 million, up 6.8 percent from last year’s $1,310,000 median and up 2.3 percent from May’s level of $1,368,500.

Other metrics continued to show steady improvement for the South Bay high-end market. Multi-million sales jumped sharply to 52 transactions last month, up from 42 in May and 36 a year ago. And sellers received an average of 101 percent of their asking price last month due to multiple offers bidding up sales over the listing price.

The figures were derived from Multiple Listing Service data of all homes sold in Santa Clara County for more than $1 million last month.

“After a fairly quiet spring, the housing market really is heating up this summer and Silicon Valley’s luxury market in particular is gaining momentum,” said Rick Turley, president of Coldwell Banker Residential Brokerage. “The high-end segment normally leads the way for the rest of the market in a housing recovery, so this is encouraging news for the entire market.”
