In a first-of-its-kind legal action that could inspire numerous local copycat complaints, two Michigan counties are taking Fannie Mae and Freddie Mac to court in separate lawsuits claiming the two GSEs have systematically dodged paying county and state property transfer taxes for years.Last month, Oakland County, which contains the state capital Lansing, filed suit against the GSEs in federal court. Two days later, officials in Ingham County, a Detroit suburb, filed suit in state court.
