Once a person gets into the rarefied air of 760+ credit score, the differences become nearly meaningless.
This is a massive assumption, but I think those that literally do not use Credit, but once did and were up in the 800+ range will likely stay there until they open a new account that gets reported to the credit bureaus. THEN, they will drop if that new account gets reported.
I never did like this # but the key is that you stay above that 760+ range. If you drop below that and your insurance comes up for renewal, they might ding you and increase the policies cost based on the lower trending score.
Otherwise, nothing to be concerned about. I always make sure I maintain 760+. I was around 810 back in July when I refinanced our home...it pushed me all the way down to 760 after that refinance (I did pay down a pt and wrapped that into the total loan) soo...total LTV technically increased a little and I'm certain that is why it dropped so much.
Meanwhile, my wife who uses literally almost no credit (is not on the mortgage and has no loans) hovers around the 850 mark.
Once I drop below Excellent, it's a trigger to stop applying for new credit.
Credit is funny, but once you have an excellent rating and most of lifes big purchases have occurred (New car + Home + CCs) I don't see how it would change much after.
If you are buying your very first home...credit is basically the most important piece of the puzzle alongside coming up with that 20% downpayment to get the best interest rate while avoiding PMI Private Mtg Insurance when you pull the trigger. Other than that its basically irrelevant IMHO.
