Only in the event of an emergency, such as a water/gas leak or electrical problem, is the Tenant to take any and all reasonable actions to minimize damage to persons and the Premises, including, if necessary, calls to emergency personnel, utility repair technicians, and/or licensed contractors. 4) Is painting the apartment something the landlord has to include every year?

An emotional support animal is not required to have any training or certification.As a landlord, you have the right to request documentation regarding the prescription of the animal but you cannot demand medical records or access to the medical personnel prescribing the animal. 

Here’s my spin on it, The area I am looking at is next to a major Military Base, 27000 employees with an addition to constant inflow and outflow of TDY personnel and people traveling for meetings and such.

You don't shut down your phones; if anything, you pay a call center to add additional support personnel to reassure your customers.

This could include photos, videos, or written statements from neighbors or maintenance personnel who have witnessed smoking on the property.

By buying an apartment complex with 60 or more units, the business can afford full time managerment and maintenance.I started off investing in single family rentals and found myself doing many lower value activities while I waited to grow big enough to make business sense to afford managers and maintenance personnel.

My recommendation is to stick with someone local, as it is very difficult to find and retain good cleaners, maintenance personnel, etc. 

Realistically i dont think you would need any regular onsite personnel in properties of up to 20-30 units and could probably manage something like that with a decent group of subs and some good solid tenant screening.

Here's my perspective:1. 100-unit and larger apartment complexes is more efficient than smaller apartments because 100-units or larger can afford a full time PM and full time maintenance personnel.

Call the personnel office and ask if are expecting any new employees moving in from out of town.
