I guess I am an example of Prosper scoring being tougher:
Loan Amount: 13,500
10y/20y/Current DQs: 0 / 0 / 0
Before / Now
Credit score: 680 / 760
Credit Lines: 33 / 29
Active Lines: 25 / 22
Balance: 23,316 / 18,841
Utilization: 67% / 57%
DTI: 41% / 38%
Inquiries: 2 / 0
Rating: C / D
Although my numbers have improved in every category, I receive a lower score for the same loan amount than previously. Still, I think that is a really big problem to give someone with proven non-payment the highest rating.
