Billionaire Wilbur Ross’s American Home Mortgage Servicing Inc., facing lawsuits by attorneys general in two states, was sued by a homeowner who accused the firm of using tactics that lead to improper foreclosures. The lawsuit, filed Oct. 25 in federal court in Dallas, seeks class-action status on behalf of homeowners with mortgages serviced by American Home going back to 2006. American Home’s “illegal, unfair and deceptive business practices victimize borrowers” across the U.S., according to the complaint. American Home “routinely and systematically assesses unwarranted fees against consumers, resulting in premature default that often gives rise to unfair and improper foreclosure proceedings,” according to the complaint. Banks and loan servicers are under scrutiny for their foreclosure practices following accusations they relied on faulty documentation to foreclose on people’s homes. Attorneys general in all 50 states have launched a coordinated investigation into the issue.
