U.S. new-home sales decreased 8.6% to an annual rate of 763,000 in March, the government said Tuesday. That figure represents the quantity of homes that would be sold over a yearlong period of time if the same number of properties were bought each month based on the rate of sales in March. Compared to a year ago, sales were down 12.6%. Economists polled by MarketWatch expected new-home sales in March to drop to an annual rate of 770,000.
