Your insurance certainly does not cover other people's possessions - for rental properties, that's why tenants have to get renter's insurance.As others have stated, your agreement with the staging company will identify who is responsible.Now, there is another aspect to "who is responsible".

You get possession but not ownership (i.e., "the deed"). 

Example, does your lease maintain that the oil tank must be full on departure and proof exists it was full at possession?

Remember, you can not take the proceeds from the sale yourself, an intermediary must take possession.

The tenant has violated a lawful obligation or covenant of the tenancy, other than the obligation to surrender possession upon proper notice, and has failed to cure such viola-tion after having received written notice thereof from the landlord. 3.

We bought it from the bank almost as soon as they took possession. 

Do you have experience and time to return to court and file a writ of possession?

Specific skills are required, most of which everyone believes they possess when in actuality most don’t possess at all;  negotiating skill, analytical ability, marketing and sales skills. 4.

Can I tell my tenants:Smoking is not allowed in the house or within a certain distance from entrances(Just like standard rules in offices)All possessions are to be kept inside your unit.

Hi @Petya Toncheva, in my opinion the principal at play here is "best and highest use" and since a room need only have walls and a door to be an office space, but needs to possess more to qualify as a bedroom you're generally better off qualifying it as a bedroom and advertising it however best fits your market.Do be mindful of total square footage and overall utility.
