From CNNMoney:

NEW YORK (CNNMoney.com) - Sixty-five of the nation's 299 biggest real estate markets are severely overpriced and subject to possible price corrections.

That's according to the latest (third quarter) Housing Market Analysis conducted by National City Corp, a financial holding company, in conjunction with Global Insight, a financial information provider.

The report named Naples, Florida as the most overvalued of all housing markets in the United States. A single-family, median-priced home there sells for $329,970, 84 percent more than what it should cost -- $180,956 -- according to the analysis.

National City arrives at its estimates of what the typical house in these markets should cost by examining the town's population densities, local interest rates, and income levels. It also factors in historical premiums and discounts for each area.

Other markets deemed wildly overpriced included Merced, California (by 77 percent), Salinas, California (75 percent), and Port St. Lucie, Florida (72 percent).

Olympia comes in at 25% overvalued.
