You want as much control as possible as a landlord, so I would try to build it into the lease.

(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.

By law, independent contractors retain control over their schedule and number of hours worked.

Cash in your control (pocket) is King...

Remember you don't have to own a property to control it.

I also could call the animal control people (I believe it's actually against code to let cats roam in the city - though nobody tends to enforce it), but that probably won't endear me to my neighbors much.... 

In my area, that would mean I would need to control at least 250 SFH.  

Remember you don't have to own a property to control it.

I hated having no control over my property, and I have a hard time trusting a company to handle things that matter so much to my income!!
