Cherry-Picking a Loan Portfolio, Revisited

Readers might remember my original post and spreadsheet http://pistulka.com/Other/?p=1473 in August 2015 called Cherry-Picking a Loan Portfolio.  That spreadsheet relied upon going through a loan portfolio and placing an X next to the loans you were interested in purchasing.
