As a symbol of the national foreclosure crisis, Jaymie Jones isn’t what you might expect. The 52-year-old Seattle-area woman worked her way up in the financial-services industry over three decades from bank teller to mortgage executive. In spring 2007, she bought her dream home in Kirkland, signing a 30-year, fixed-rate mortgage. Then, as Jones celebrated New Year’s Eve on a beach in Mexico, the call came: Her division was shutting down. Jones tapped her savings over the next year and tried for a loan modification, but in the end, the bank filed to foreclose. The dream was over.
