From my limited knowledge and experience, the cons would be that you have to maintain the LLC in both states.

We maintain a contract with a local towing company who gave us official towing signage to post that is compliant with local law.

I know all this off the cuff crunching may seem humorous but I"m just trying to quickly ascertain how good of an idea it is to invest in rental properties with the main idea being to passively maintain a middle class living? 

The difficulty is actually getting into high-quality properties at a high quality price, and maintaining a healthy working relationship with a high quality team over time.

The other 5 doors have tenants that pay on time and maintain the properties great. 

(A) A landlord who is a party to a rental agreement shall do all of the following:(1) Comply with the requirements of all applicable building, housing, health, and safety codes that materially affect health and safety;(2) Make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition;(3) Keep all common areas of the premises in a safe and sanitary condition;(4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;(5) When the landlord is a party to any rental agreements that cover four or more dwelling units in the same structure, provide and maintain appropriate receptacles for the removal of ashes, garbage, rubbish, and other waste incidental to the occupancy of a dwelling unit, and arrange for their removal;(6) Supply running water, reasonable amounts of hot water, and reasonable heat at all times, except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection;(7) Not abuse the right of access conferred by division (B) of section 5321.05 of the Revised Code;(8) Except in the case of emergency or if it is impracticable to do so, give the tenant reasonable notice of the landlord's intent to enter and enter only at reasonable times.

I am sure it costs a pretty penny to maintain this site.

Let her know you need your house back for your own use, nothing personal against her, and apologize to her if there was some misunderstanding.About the service calls.... no need to be annoyed by them, they are part of doing business and are necessary for maintaining a home.

I try to keep well maintained properties and am in the replace with high quality components rather than slap dab patches that need to be redone every few months. 

This would be very difficult to maintain if you're not living in the house yourself and keeping some order established.
