A real estate agent is a good source for finding out the status of the local housing market. So is your statewide association of Realtors, most of which are continuously compiling such statistics from local real estate boards. For overall housing statistics, U.S. Housing Markets regularly publishes quarterly reports on home building and home buying. Your local builders association probably gets this report. If not, the housing research firm is located in Canton, Mich.; call (800) 755-6269 for information; the firm also maintains an Internet site. Finally, check with the U.S. Bureau of the Census in Washington, D.C.; (301) 763-2422. The census bureau also maintains a site on the Internet. The Chicago Title company also has published a pamphlet, "Who's Buying Homes in America." Write Chicago Title and Trust Family of Title Insurers, 171 North  Clark St., Chicago, IL 60601-3294.
