@James Wise When reading his reply, my interpretation is that he is not providing "property management", in his opinion.

If you need to modify the agreement, you need to keep track of the notices/addendums and then over time interpreting the lease becomes messy because the agreement is actually the sum total of ALL of those documents over time.

Am I interpreting that correctly? 

@Brandon LashmetI would interpret this as you are not exempt.

IE- it requires interpretation and I could see how a CPA's interpretation could differ from one to the other. 

You should ask a lawyer in that state if that violates a statutory provision or case law interpreting your landlord-tenant act.

There is a legal concept that when a contract is ambiguous that it will be interpreted in favor of the party that did NOT write the document.

Your tax pro needs to read these and interpret the findings. 

Therefore you are taking bad information and then interpreting it incorrectly which is double trouble. 

But even this, as noted, is explicitly allowed in Ohio, but rather open to interpretation.
