I had to get a gas stove for the kitchen because the electrician said it would have overloaded the existing electrical power or amps (I'm not an electrician so my terminology is probably incorrect) and it would have cost more if I wanted an electric stove. 

This coverage does not extend to the tenants belongings.Many times this coverage would be used to cover a stove, fridge, washer and dryer if you are providing that with your rental.

Also, AC units and stoves can dig into your expenses if they're older.

We also had a full commercial stove with griddle.

I'm sure an electric stove and fridge would need special electrical. $100k install cost doesn't sound bad too with everything included.

They do have separate "kitchen" areas but don't include a stove/range, so I'm not sure if this qualifies as a kitchen in this case.

I have had tenants add blinds, curtains and even a brand new gas stove.

Definitely separate this from any rehab, you don't want to make it sound like its a quid pro-quo that you are making it nicer because they will try and balk "oh I don't need a new stove, etc. just keep the rent the same."

Some of the items they have entered include:Blinds too long and don’t turn smoothly, tub plugged, stove dirty, door bell not working, dishwasher smell, we did get her new dryer, refrigerator drawers cracked along many more.Property management sends someone over and I pay several hundred for each of these.

It already has stove and fridge .
