So , lets see if I got this....
Your insurance company (gotta have it , it's required by law, sponsored by the insurance lobby) want's your credit rating before they "calculate" your premium. You pay less if you have a high credit rating and more if you have a low one. So you're penalized if you haven't paid enough interest ......
Now , more about loans and insurance ,,,,you get a loan to buy a new car , the bank requires you to have total full coverage , they own the car , not you. Don't think so ? , just miss a few payments.
Home /property mortgage loans , ditto.
Getting a longer payback time and a lower rate still ends up with the same ,or (probably) more interest paid over the life of the loan.
Credit rating and other loans works the same way.
The whole thing is set up by the banks/corps that make the profit...that's what really matters to them .
