As long as you rent my unit, I want to make sure you have liability coverage so if something happens, I can get reimbursed.

You are still paying the city and being reimbursed by the third party. 

You’ll need to reimburse them for GL insurance as well, as well as some sort of equitable, but low fee. 

Roof and parking lot are huge expenses even if can be passed on to the tenants they can't take the additional to CAM all at once so landlord pays for new stuff and gets reimbursed over a long period of time.

Additionally, I am in a somewhat similar position to you: looking for a place for my family to use, and STR in between.Regarding expenses:- Electric- Gas- Water- Internet- Netflix/Cable/etc- Paper product- Cleaning supplies- Coffee for guest- Fairly regular replacement of linens (sheets/towels/wash clothes)- Insurance- Taxes- Airbnb Fees- Local fees/taxes- Cleaning costs (yes reimbursable, but there is a fine balance between covering costs and not pissing off potential guests)- Mortgage costs- Maintenance costs- LandscapingThere are lots of nuances to running an airbnb.  

And you need to be meticulous with your bookkeeping, as HM lenders want paid receipts for every single item before they will reimburse you for each draw.

Furthermore, I'll assume what you are also attempting to do is use the 2% commission equivalent to cover that portion of the down payment needed to close on the purchase, which would give you a larger equity position in the deal.If the above assumptions are correct, the simplest method would be for your group to front the cash equivalent to the 2%, which will be reimbursed to you through the 2% commission collected at closing.

Once you have yourself organized, you can either start an account w/ a propane company, and bill the tenant yourself for reimbursement, or leave it up to the tenant to find a company, start an account, etc.

A homeowner or end-user will generally see their project each day and act appropriately, may be more likely to sue to fix the problem or get reimbursed, plus protection laws are more geared toward end-users than investors.
