Seymour, understand FICO for what it is, and nothing more.
FICO is NOT an evaluation of your credit strength. It is an evaluation of your risk of repaying. Donald Trump and Archie Bunker are equally evaluated, not on their income or debt, but rather on how prompt and consistent they are in paying their debt. That is FICO.
If you perceive a folly in FICO, then I would ask you to first perceive the folly in the mind of the lendor using it. Would any lendor, once you apply for a half-million dollar loan, pull your FICO, and stamp "approved" or "not approved" based on your FICO? KInda silly,huh? Without knowing your income, debt, marital status, etc., all of which are factors that are prohibited under the FCRA from appearing in your credit report, and thus being scored by FICO?
Dont stamp FICO or any credit score, regulated by law in what it cannot include, as being an evaluation of credit heatlth.
