It goes on to say the property manager / agent below is authorized to order repairs and/or service to the building.I live approximately 75 miles and it would take me roughly 1:15-20 to get to the property.Adding to the pain....It also says *** New Applicants must complete Rental Property Training within 6 months of application.

That means if you've got a manager that charges you $100 to make one-off visits to change a light switch cover, authorizes repairs beyond what your contract says, and so on, you need to be cognizant of perhaps finding another manager.The whole beauty of having a PM is not having to do it yourself.

I've taken the effort to get them signed by their authors, when possible.The challenges facing most new, would-be investors are no different now than when I started nearly 40 years ago: I don't know what I don't know until I need to know it. 

Articles of Organization (depending on the entity you choose), Statement of Authority, Operating Agreement (can be optional), Employer Identification Number (EIN).

My property manager isn't providing information about if the housing authority will catch up her rent or what is going on. 

I also own and manage medium term rentals where the neighbors don’t like the changing guests and call the authorities to complain.

I also had to have an office inspection prior to obtaining the authority to pull credit reports.  

I don't believe you can just rent to section 8 without having gone through the approval processA rental becomes Section 8 approved when the landlord accepts an applicant with a HousingChoice voucher and requests their local Housing Authority conduct an inspection.

If you lack the constitution to be the boss of your property - to conduct inspections, enforce the terms of your lease agreement, communicate with tenants from a position of authority then you should consider a property manager and see if they do better with your asset.

The longer answer might be to talk to the permitting authority and find out from them how much would be grandfathered in - if any - and how much really has to be re-piped.
