eBay for loans

[Shoe]

Does anyone know if you can view loans that have already been funded and check if the buyer has been making his/her payments or not? I would be interested in researching different types of listings to see what type of loans are most likely to be paid/default etc....

Any listings I look at don't seem to give any information on if the buyer is actually paying on time or not. Do you have to actually be a lender on the loan to know this info?
