this occurred to me when i started thinking, "having a high FICO score can save you money, but unless you're buying a house, you can't really generate positive cashflow with it." so the next question was, "how can i generate positive cashflow using a FICO score?"
but maybe there is something here: say IR's FICO score is 825, and mine is 600. i need a loan, but a 30-yr fixed is 9.25% for me and IR can get the same loan for 7.25% (as a 2nd residence). so IR becomes my banker and lends to me @ 9.0%, for a spread of 175 basis points. now if IR can buy some sort of PMI insurance (i know it doesn't exist, but let's just talk theory) for under 175 basis points, then IR has positive cashflow.
i wished i had a fail-proof idea, IR. but you know, conceptually, this is just a credit default swap.
