Well not quite everyone, but it seems like a lot of personal finance bloggers just don’t like it. I’m not in that camp, nor am I in the other camp of die hard propser fans. I think it’s still to early to tell if prosper makes a good an investment. At this point, I’m going to amend my original verdict to “watch and follow” I realize my initial calculations from Earning Money Part 5: Prosper.com were not really reflective of true performance. I used the average default rate for the entire period. This is problematic for two reasons. 1) Loan volume is biased toward more current loans 2) It probably takes at least a few months for a loan to go into default. Coupled with reason one this would bias the default rates down.

I think it’s still early in the game before we can make a decisive judgement on if Prosper.com is a worthwhile investment. Early adopters reap greater rewards and greater risk. In the end I do feel a disciplined propser investor can achieve market returns that beat out a savings account and should provide returns that are less correlated with the stock market. How much work is involved to achieve that is unclear. Is it worthwhile? Who knows. Only time will tell. Once I have a little more personal experience with prosper, I will do a more thorough analysis. I’d love to get my hands on all the actual raw data - there’s a goldmine of data there. If anything that’s one problem I have with propser is the inability to properly query data.
