House prices, after falling for more than five years, are rising again. All the major sales-price indexes show that there have been modest national increases in recent months, even after adjusting for seasonal patterns.

When foreclosures and distressed sales are excluded from the data, prices are up even more. And we should expect further gains: The asking-price index, a leading indicator of sales prices, published by Trulia Inc., climbed at an annualized rate of 3.3 percent in the second quarter of this year, adjusted for mix and seasonality, and rose in 84 of the 100 largest U.S. metropolitan areas.
