What is the hardest part of DIY management?

[Nathan Gesner]

There are pros and cons to self-management. Some landlords are very successful. Some lose their shirts, destroy their health, and even ruin relationships. Most land somewhere in the middle.

If you have experience as a DIY landlord, what has been most challenging about it? What hard lessons did you learn that you could share with readers?

My biggest problem has been the same as @Mike Dymski - not being large enough to have handymen, HVAC, plumbers etc that work just for me. Having to share means working around other big jobs, etc and doing more stuff myself than I would care to do for lack of help.
