There are definitely members who have had more than 1 loan, but perhaps not both active at once. If the Q+A can be believed. I haven't poked around in that LoanStatsNew.csv file before so I cannot really comment on it. It's possible that memberid is an auto increment field which doesn't remain the same for a given person necessarily.
Perhaps a more plausible explanation: Don't you have to use a different email address to get a 2nd loan? So you would be assigned a second memberid anyway.
Not sure I have an issue with this. Can't force peeps to keep higher interest rates loans than they deserve. Refi seems fine to me, as long as they aren't truly churning (applying higher interest rates with the INTENTION of refinancing later)...
There's a big difference between allowing someone to refinance and sending them emails ASKING them to refinance so LC can get another origination fee, not to mention 1% of both balances. LC should consider waiving the 1% servicing fee on the lump sum payoff under these circumstances.
