Obviously there are bragging rights to having an 800+ score (or any really high score), but from what I've seen as a newbie to credit scoring, there's a point where you're really not getting a tangible benefit to a higher credit score. Meaning, you're not getting a better interest rate for having a higher score.
Where is this point? 750-760 range? The FICO Scorewatch page seems to indicate that a 720+ will get you the best auto rates, and a 760+ the best mortgage rates. After these scores for the respective loans, is there a benefit to going higher?
Realistically the only real benefit is probably bragging rights. There may be a few credit products where you can obtain better rates or benefits with a score higher than 760 but most high achievers probably won't see any difference.
ETA: I am not a FICO high achiever so I am only speculating about this.
I believe you are very accurate. My Realtor and Loan Officer say 760 and up for the best mortage rates.
