Jenn Ablan and I have done a lot reporting on Mortgage Resolution Partners’ plan to get county governments and cities to use eminent domain to seize and restructure underwater mortgages. As we’ve reported, it’s an intriguing solution to the seemingly intractable problem of too much mortgage debt holding back the U.S. economy. But it’s also a controversial one that threatens to rewrite basic contractual rights and the whole notion of how we view mortgages in this country.
