The thing is i don't know how to rent it to other people ( preferably students) because 5 minutes away from my studio apartment, there is a college nearby. i bought all the furnitures in the apartment and the contract is in my name.

Tenants will always want you to move out certain pieces of furniture, even if they want the other pieces, unless they're a short-term renter. 

Maybe they want to measure the rooms to see if their furniture will fit.

I'm willing to bet it's a bunch of old used furniture and nothing of real value. my process is to document what was left behind and then dispose of it, clean up the unit, change the locks, and rent it again.

Rent to owner does not include cost of any meals or supportive services or furniture which may be provided by the --67.87.xx.xxx

missing furniture in upper unit and the huge scratches in wall 18' up in stairwell.

So, they leave all their furniture, and sublet it as furnished with my permission.I got to where I did not want parents as co-signers. 

I had to remove a piece of their furniture myself. 

Did some work on a leaking faucet, got rid of some old furniture and replaced it with new, made a ton of tasteful decorative updates to decor.

They let it wander loose in the house and it dug or chewed the carpet under the furniture.
