Kind Distance Frustration

[Krissi Miramontes]

Newbie help needed!  
I purchased 2 SFH and one duplex in Toledo last year. Hired a one man's show property manager after 10 months. Now self managing but trying to find a PM.
1 is going fine, 1 is going but always needs work on something (no CF yet), and then there is the duplex. It has been an awful pain. Started replacing and getting rent ready. New HVAC stolen, electricity being stolen by neighbors. 
I thought I found a PM but I’m not sure now (It is a big company and not very flexible). 
at this point I’m wondering if I should sell at a loss or try and get it ready again with a new PM.

Duplex purchased for 45k, put in 10k. Now need to put another 10k, plus management fees. Will rent for $1200 total. Is it worth moving forward or just sell for 30k and get out?

The SFH next door I paid 50k, put in 10, and needs another 5. It is rented for 775.
im looking for the best thing to do at this point. 
I’ve started flipping in my market in CA and like it WAY better thank LD investing. 
should I keep pouring money into these tiny things for long term returns or cut my losses?
