I have a foreign rental property that's been in service since 2013.

I list my rentals on Zillow, and I have an agent profile on there, but I dont use any of their other services. 

People are often evicted from places when ownership of a property changes hands for no reason other than the owner wanted to sell the place empty or the buyer wanted to start with a clean slate of tenants of their own choosing. 

Every tenant needs security for their private roomYou may get additional rent but you can also have additional work (dealing with more frequent turnover, common area cleaning/maintenance).

Clean up any grease spots on the pavement. 

Make sure it explicitly explains the process for termination if you are unhappy with their services, but especially if they violate the terms of your agreement.3.

It makes me go crazy because I want to offer excellent service, but then having to outsource and worse, wait an extra day or more because the guy I called is booked.Has anyone else gone through similar feels?

My jurisdiction has us sign a declaration stating we understand the risks associated with acting as Owner Builder:https://www.sandiego.gov/sites/default/files/legacy/development-services/pdf/industry/forms/ds3042.pdf

Services that you 'can't shop for' are a rip off.

You can even get investor loans on 1-4 unit properties that do not factor in your income, only the debt service coverage on the property you are acquiring.
