I think there must be something wrong with your handling of the Prosper homeowner field.
Your breakdowns show very few homeowner=true loans.
For example, if I filter all loans 2016-01-01 and later, you show 68,485 loans, of which only 13 are homeowner=true !
That doesn't seem like it could be correct. I've bought a lot more homeowner=true loans than that during 2016 !
This should be fixed now. We had a problem importing listing data for some boolean values. This was only a problem with historical data because of a conversion issue when saving to the database, but it should be resolved now. Thanks for the heads up.
Indeed, seems to be working now (no longer treated as boolean).
Thank you again for your quick response.
