It will be a hire rate that market average, but at least it will be principal and interest bearing.

Honestly, if you are out of state you should probably be hiring property management regardless of troublesome tenants in the present.i don't know how experienced you are as an investor or if this market you're buying in is one due for exceptional appreciation but realistically $160/mon cashflow is not a move i would suggest in the short term considering you're a world away and any number of things could go wrong that would wipe out a years worth of cashflow overnight. 

This leads to the problems worsening, and I end up having to hire an emergency technician to handle the repairs.

I have heard from others that you should learn and research tax if possible for your first property rather than hire CPA right off the bat as it should be less complex from strategy.

Just hire an electrician, hire a plumber, and you can do all the rest.

Put a virtual potential call center at the front line to field calls and this feels like something that could be done cheaper than what appears to be $26/door/mo.

I definitely understand why you want them but you're better off hiring someone to manage in my opinon. 

I hire a property manager and I have never in 10+ years of having a PM had a tenant reach out to me, if they got upset or had a complaint they dealt with the property manager.

You always hire professional cleaners if it's an old person's home and construction cleaners if it's a disaster area.

Many of our clients in similar positions keep the investment and hire a property manager - that allows them a completely hands off investment, while continuing to build equity.
