One of my tenants was a severely disabled, retired doctor that couldn't lift her head up to look in her kitchen shelves or drive a car.

I used to designate shelves for each guest in my own fridge, but I got tired of cramming all my groceries onto one shelf.

The one I had like that started at the walk-through asking if we'd change up the walk-in closet that the unit already had that was enormous - can we extend one of the rods and take out the shelves on that end so the rod is longer? 

Fourth, add a few decorative touches to make the home more appealing: Place a flower pot full of marigolds or brightly colored welcome mat by the front door; Set a colorful bowl of fruit on the kitchen counter; Install some decorative shelving on bathroom wall; Paint one of the walls in the living or family room an accent color that harmonizes with the rest of the room.Fifth, learn to live with and accept what that renter does with YOUR house.

I have allowed some requests like I want to plant a garden or I need storage shelves but the sooner they start asking for changes to the structure the more likely they are high maintenence.You could also opt for a pm.

To soften the blow of the rent increases, take care of any maintenance, repair issues immediately and add a few cheap upgrades to the unit, extra shelving for the garage, add an exterior light or replace an outdated one inside.

You can have some type of built up shelving to keep things off the floor.

And after this tenant moves out, just remove it.I learned that when a tenant is viewing an apartment and they ask things like can we add more shelves in the walk-in closet, or darkening curtains because the street light is too bright, or put in hardwood flooring or paint a different color, etc., they will be high-maintenance tenants. 

I am thinking about adding additional storage in there, either shelves or cabinets, as well.

The people side of all this is MUCH MORE important than a buck here or there.If the holes are nail-holes for hanging clocks, pictures, or small shelves or whatever, I wouldn't charge.
