Josh and Tayla Thomforde thought they had a deal to buy a three-bedroom house with a fenced-in backyard and room for their family to grow. But the nation's latest foreclosure quagmire scuttled their plans. Three days before closing on their first home, they learned that Ally Financial's GMAC Mortgage unit was taking the house off the market. The house is a foreclosure, and Ally and other banks are suspending or at least slowing down foreclosure sales as regulators examine whether banks filed foreclosure documents without confirming their content. Now Tayla, 25, and Josh, 26, aren't sure what they'll do when their apartment lease runs out at the end of November. "We're a little discouraged," Tayla said. "All the homes in our price range were foreclosures."
