First the Wall Street Journal and now NPR, is following the news originally broke by HousingWire that a “Robo signer” is partially responsible for GMAC’s foreclosure woes… Jacob Goldstein reports: How did a middle manager at GMAC Mortgage sign off on 10,000 foreclosures a month? He didn’t read the paperwork like he was supposed to. The company (part of Ally Financial, a Planet Money sponsor) recently halted evictions in dozens of states, after news of the robo-signer came to light, NPR reports. The case — which could allow thousands of homeowners to challenge their evictions — has triggered other reports this week of sloppy foreclosure practices.
