I'm an investor, flipper, and property management company owner in central CT. 

We own several properties and now manage 18, with a few more coming online soon. 

Angel investors might be interested, but you'll likely have to give up a portion of the ownership or future profits, and there could be potential complications in managing the investor's expectations and involvement.

I don't know how much you will be paying a property manager but add that in.

I have some flexibility but rely heavily on my team for admin work and the day-to-day operations of property management.

Rank them from best to worst in management cost*4.

Detailed studies break down every component for maximum depreciation ($3,000–$10,000).

(And - full disclosure - I will be using a mail forwarding address also and only occasionally actually hosting meetings at that location... it's like a 'WeWork' space, I generally work from home and my managers are on-site at the parks...)To everyone's continued success, and due diligence,-jl-

“it is VERY hard to screw up when buying i.e. a duplex in good condition in a desirable neighborhood and either self-manages or hire a quality PM to manage.”excellent point 

It sounds like you had a terrible manager.
