Getting Wise to Mortgages.

Reports on comparison shopping for home mortgages in the United States. There are tools on the Internet, such as www.mtgprofessor.com, that can help borrowers determine if they are getting a good deal. Fair Isaac Corp. and Bankrate Inc. are improving their Web sites and making mortgage shopping easier. Advice is given to consumers about researching and comparing mortgages, as well as getting multiple offers. Wharton professor emeritus Jack M. Guttentag says that consumers should not assume that Web sites such as LendingTree will protect them from overpaying.
