Some issues a broker may consider to your wholesaling:Perception of the public, perception of the property owner.Dealing for yourself doesn't relieve you of Laws of Agency, facilitating a sale, are not escaped by saying you are dealing on your own behalf.

FSBO's in most cases have tried to sell their homes themselves, and have had their real estate listed with a few agencies.

Considering regulatory agencies have an interest in making sure the public is protected,  licensing coursework covers everything any real estate investor needs to know, such as the different types of valuation, real estate, contract and tenant law, equal housing and more.  

A simple call to the local code enforcement agency should be able to reveal any outstanding liens and fines.

Liens to government agencies don't go away by turning a "blind eye" as you no doubt understand.Many types of liens can fall off attaching in time.

Most for sale bank owned homes are under the same listing agent or agency within a given area.

I don't want to force them to move, but I feel I must make some adjustments to rent rates as well as talk to my insurance agency.

If you don't have a written lease from the purchase I'd check out your local and state agencies for advice on what the law is in the state in addition to consulting with an attorney.For example, where I am (St Louis, MO) the city has a "landlord's guide"https://www.stlouis-mo.gov/government/departments/...which includes things like sample applications, information on the eviction process, and citations to the state landlord tenant law.The Attorney General puts out a state guide on Landlord Tenant lawhttps://www.ago.mo.gov/docs/default-source/publica... though an attorney would be the most helpful when it comes to knowing what paper trail you need to create.  

Yes, I understand how "wholesaling" works and I think phrases like "grants the right to market the property for sale" are what get non-licensed wholesalers in trouble with licensing agencies and the law.My understanding of how this should be done is with a standard (or better written) purchase agreement with the "Buyer" listed by name "and/or assigns."
