Anyone self-managing 50 or more doors?

[Krishna Chava]

I self manage 75 doors with a 50% partner. We have maintenance guy who lives in one of our properties and takes of issues as needed. So, far we are doing OK, probably as good as an average property managers. My main concern is that I can't get to properties often and don't have control over who lives in there as long as someone is paying rent.

When I listed my vacant properties, I had very desirable prospective tenants  turn away because they like tenants but not "neighborhood". 

What are your issues and pain points? Any tips?
