Flutterby™! : credit scores for sale

Interesting story about how lenders are nervous about the practice of "piggybacking" on FICO scores.

Estruch paid $1,800 in December for three credit card spots, and by January, his FICO score jumped from 550 to 715. In mid-March, he closed on his four-bedroom beige stucco house after obtaining a 30-year fixed-rate mortgage from a unit of American Home Mortgage Investment Corp. It carried a 7.5 percent interest rate and required no down payment.
