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.

There is always some things left behind. things like inside stove, refrigerator, inside the Owen, corners, some cabinet shelves, window frames some residue on the walls etc.

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and add a few cheap upgrades to the unit, extra shelving for the garage, add an exterior light or replace an outdated one inside.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.

My tenants have installed shelves in rooms, etc. and I haven’t given them trouble mid lease.

Even things like paper towels they used for cleaning, an empty trash can, etc.Did not empty and wipe out all cupboards and cabinetsDid not clean appliances - this means taking shelves out of your fridge and washing them, scrubbing the stove top clean, cleaning the oven, cleaning inside the microwave, etc.

I'd take out the shelves. 

Even during the height of the social-distance measure, with all the businesses closed, I still had apartments and small houses flying off the shelves.
