I'm curious too since we plan to move next year. We've been retired for a few years and bought a new motorhome a few weeks ago. We wanted a bridge loan so that we could get the new one then sell the old one. It took over a week to secure a loan because we haven't borrowed money since our mortgage in 1993 which has been paid off for almost 20 years. The lenders said we have "shallow credit" because we have no borrowing history. We were finally able to get a loan by sending them statements from all our IRAs, listing all our other assets (motorhome, cars, airplane, motorcycles), and giving them 2 years of tax returns. At least when we get a bridge loan next year to switch houses we'll have established credit with our RV loan which should be paid off by August.
