Also then is your job rock solid?

In other words, most PMs cannot afford to put in the significant amount of effort required to correctly manage in a C area for the minimal returns a single property produces in a C area.

You rock.

I've seen some have had difficulty selecting property managers (and in turn produce bad tenants with negative cash flow) in Reading, and since I'll be an out of state investor I'm wondering what some of the best PM or PM companies are?

Turnkey would produce better returns than this house and I have a good relationship with a local company.

Here is a nice letter written in Market on a wall, meaning the wall had to get new Sheet Rock as it would have taken tons of paint and time to cover (easier to put up new sheet rock).

.- FHA can qualify on their 5/1 Adjustable Rate Mortgage (ARM) at a payment based just on the starting note rate while conventional 5/1 ARM's have to qualify at the starting note rate + 2.00% fully amortized payment which rocks your DTI ratios and makes it a lot harder to qualify for.

The highly desirable areas of DFW are not producing many cash flow positive deals, simply because market rents haven't caught up with property values. 

Deals are not produced when and where and how you want them.

But it is something to keep in mind for the future if you find that your RE investing produces greater returns than your more traditional retirement investments.
