50 Most Expensive Small Towns In AmericaAccording to the National Association of REALTORS®, foreclosures and other “distressed properties” sell at discounts of 20 percent of more. Discounts of that size affect pricing in the broader housing market, too. It’s among the reasons why median home prices are dropping.

Not all markets are affected equally, however. In a recent BusinessWeek analysis, it was shown that one-third of the nation’s 50 most expensive small towns experienced a median price increase between 2010 and 2011.

Topped by Sagaponack, New York — a town of only 582 residents — each of the cities carries a median home price of more than $1,000,000, and a total population of 10,000 or less.

The list is dominated by New York and California, with 22 and 13 entrants, respectively. The rest of the towns are spread throughout the country, including Chilmark, MA (#28), Yarrow Point, WA (#29) and Belle Meade, TN (#48).
