Funny that these CPS guys are selling notes through Prosper. Now I can see why they could afford to pay me 10% for two years: because they're relending at 17-22%.
I clicked on a a random car loan:
http://www.prosper.com/invest/listing.aspx?listingID=414868$10,956.56 principal balance offered at premium
$11,277.66 @ 13.20% [that's net yield, but not net of servicing, AFAICT]
Borrower interest rate:
17.70%
Servicing fee:
3.00%
Loan-to-value:
118%
WTF, 118% LTV at origination and selling for a premium? Yow, that is one spicy meatball.
