Is it Really 850 Credit Score or Bust?? We do not think so!
You should go for a 760+ Credit Score instead of an 850 Credit Score, because most things can be achieved with a score of 760, like Amex Cards, Low Mortgages, Low Car Loans, Good Insurance Rates etc.
We say get this first, then if you want a personal goal to knock out of the park, then go for the 850 Credit Score. The most important thing is to plan out your credit journey for prestige, lifestyle, and financial leverage and you will be financially stress free.
