If multiple neighbors contact the property owner or local authorities, it might increase the pressure to resolve these issues.

Does your local housing authority allow this type of arrangement? 

My challenge is that I am not authorized/signed up with the city to take on CHA checks, so that will take a while to get a tenant.

A closing / title company can handle the transaction but may want to get a lawyer to draft the documents.Assuming you are buying in your name and not a LLC - if a LLC then there would need to be additional docs like a authorization for LLC to borrow $ etc

What authority under the Trust does your father have to sell the property? 

Tenants should have no authority to engage contractors without authorisation from the landlord and if they do they should never be compensated by the landlord.

A PM would have taken most of that.I have seen too many OOS investors fail buying cheap properties in rough areas not recognising that over time capex exceeds cash flow.

I've recently started an eviction on a S8 tenant of mine in Detroit.The process will be identical to a normal, cash paying tenant with one big exception.The housing authority will continue to pay the voucher amount during the eviction process. 

It is the role of the legislature and municipal authorities, not the courts, to consider any policy concerns related to STRs.

They might tell you they can't release any info to you without SS number or some kind of authorization or detailed info.Who knows how fast a lender forecloses.
