You’re basically correct (although 95% of income is drastically overstated, it can be far less than that), but I don’t understand why you can’t wrap your head around that? If you’re never taking on any credit debt then of course you will have a non existent credit score. If I’m a lender, how would I possibly know you’re capable of paying back a loan without some audit trail of your past ability to do so? It seems an incredibly simple concept to understand.
