At the end of the day, what's the least amount of a pain?

[Pat Jackson]

I'm asking this from a "I'm done buying and am now holding my portfolio"

For folks that are enjoying their portfolio more than building it, what do you find to be the least amount of a pain in the ***?  The least time consuming?

I've read a lot of articles and forum posts, and listened to a plethora of podcasts.  Let's pretend one has 100 units, and they decide to stop buying.  They've now entered the "hold" part of their career.  You could have:

100 single family homes

25 quad plexes

50 duplexes

1, 100 unit apartment complex

This is hypothetical, so let's pretend they're all in a C+ neighborhood.  All under property management.  Thoughts?
