Credit score worth to keep building past 780

[Yuriy Panchelyuga]

Just some back round info I make about 150k a year and I have a 780 score one rental property. Do you guys think it’s worth looking up every way of raising credit score and doing it ?

for example I know multiple cards can increase the score should I get more cards just for this ?lastly what’s the best resource for raising credit score if it is worth it
