Even as nationwide home prices rose to record-high levels, in 21 of the 50 largest metro areas values have yet to return to their pre-Great Recession peaks.

The nationwide median home value in October was $203,400, up $12,500 or 6.5% from the previous year, according to data from Zillow. This is approximately 3.3% above the $197,000 peak in the median price for the months of April and May 2007.

A trio of metropolitan areas, San Jose, Seattle and Las Vegas, posted double-digit price gains on a year-over-year basis. The median price for San Jose increased 12.3%, while in Seattle it was up 11.7% and there was an 11.2% increase in the Las Vegas area. Home sales in both San Jose and Seattle benefit from those metro areas being centers for the technology industry.

But Las Vegas was so far underwater from the effects of the Great Recession, prices there today still are nowhere near the peak value that was reached in May 2006. Things went so far south in Las Vegas that by April 2009, nearly three-quarter of home sales in the city consisted of properties sold after foreclosure.

Even as the Detroit market continues its recovery, its peak value was reached in June 2005, the longest period of any large city that prices have not rebounded.

Here are the 12 metropolitan areas among the nation's 50 largest by population where home prices have the largest percentage deficit to their peak value, according to Zillow.

The prices are based on Zillow's own estimates of the median home value. It includes the value of all single-family residences, condominiums and cooperatives, regardless of whether they sold within a given period. The estimates are seasonally adjusted.
