Usage of Home LOC impact for credit score

[Vincent Chen]

Had credit score slightly above 700, would like to get LOC based on my rental property from penfed, just curious the usage of LOC impact for my credit score.

Let's say if I got 100k LOC on my rental property, if I use 80k of them and make each payment on time, what is the expected impact on my credit score? Since 80% is high if it is considered as similar as credit card.

Hope experts give good inputs, thanks.
