Presumably this is a condo so your capex will be limited, but you'll still need to think about occasionally replacing appliances or furniture, or cosmetic upgrades as time marches on.Overall your margins on this are pretty slim - there's a lot of variables in STRs and while they can be amazing investments, you've got to pencil out things for the worst case scenario so you don't end up losing money.  

You charge them for the house and for the use of the appliances, furniture and all little things like a kitchen utensils, vacuum cleaner, garden hose, grill, sheets, shower curtain, etc.  

Setup expenses includes furniture, appliances, cookware, repair services, and some supplies such as soaps, toilet paper, tissue paper, etc. 

I was on the fence about going the Airbnb route because you'd have to buy furniture, decorate, etc and definitely a lot more upkeep and wasn't sure if it was worth it due to location of ER, which is more of a family-oriented neighborhood.

The grass is high and the house is still full of furniture and personal items.

Is there a better way of doing this so that we can have the property cleaned and any maintenance done before the new tenants move their furniture in?

They are far more important than resetting the depreciation clock.It's like choosing furniture for a house that is not built or designed yet.

The lease has a tenant allowance clause that stipulates: "Provided the Tenant is not in default of its Lease, Landlord shall grant Tenant an additional allowance of $5.00 per square foot to be used toward as improving the Premises including moving costs, furniture, fixtures, equipment, cabling/network costs."

Whatever matches your furniture.

Furnish the rooms with low cost furniture that looks nice (queen frame, mattress, dresser, nightstand) and charge everyone equal utilities (I recommend $50 a month).
