Long & Foster Realtors, the largest real estate firm in the Washington area, is one of the top-ranked real estate firms in the country, according to the Consumer Reports survey.

Long & Foster, a 22-year-old firm with 173 offices from Baltimore to Norfolk, scored a 77 total on the overall 100-point home-seller satisfaction index, which made it the second-rated firm in the country, according to the survey of 72,000 Consumer Reports readers.

Topping the list was Edina Realty, which operates in Minnesota and Wisconsin and received a 78 percent approval rating among Consumer Reports readers. Long & Foster edged out two other national firms -- Re/Max and Merrill Lynch Realty, now known as Prudential Real Estate Affiliates, both of which have offices in the Washington area.

"We were thrilled," said P. Wesley Foster Jr., president of Long & Foster, who attributed the strong ranking to good sales agents and an accomplished training department.

Several large national companies left readers more dissatisfied. Century 21, the largest brokerage firm in the country, won a 69 percent approval rating, while 68 percent of the readers surveyed who had sold their homes in the past four years were pleased with the performance of ERA Real Estate.
