Have a frank conversation with the property manager. 

Self managing should be easy, if not then that Realtor can probably help you with the rental side of it. 

I have been in property management for 20 years, almost 3 years ago I moved to Birmingham AL to start my investment journey.

I’m in the process of managing 18 units and have a full-time job.

Quote from @Brandon Vukelich:If you buy a vacation rental in Hawaii, then you're tied to that location.

20% is not high for managing a STR.

Yes, it eats into cash flow, but bad management (or self-managing with no experience) can cost you way more in the long run.

@Andreas Mathews admirable, but make sure you do some research so you understand what a PM can make.Starting your own PMC business will require 75-150 doors to make a decent living, depending on gross rents and your fee structre.Working for a SFR PMC as a PM, will require a RE license and you usually get paid a percentage of the gross rents the portfolio of owners/properties you manage generates.

Just make sure the management part is taken care of.

I would like a book or program recommendations in order to learn how to purchase and manage the extended stay hotel.
