Tons of deferred maintenance and a lot of work to do to clean up this mess. 

Make sure everyone knows a cleaning schedule, expectation for common areas, how are you splitting utilities, guest policy, etc. 

But using that mindset, so is landscaping, plumbing, or clean out during turnover.

My goal is to add verbiage within the lease that will decrease any tiffs between tenants for the common spaces and how to set expectations and promote group effort with cleaning the common areas/shoveling snow/personal dishes/shared fridge/laundry/having guests and so forth. 

3.Draft a written agreement where the property owner retains full ownership of all guest funds (nightly rates, cleaning fees, and taxes), while the cohost invoices for management fees and reimbursable expenses?

Its against my loan terms, and you cant stay at a prperty that is being shown it has to be clean.

The deal was contingent upon 60 day due diligence and a clean Phase 1 environmental assessment.

My local Airbnb rep said the algo does consider cleaning fee too so try to be lower or even with your competition. 

I had a few properties when a lady that owned a cleaning company I had contracted with previously approached me about combining forces on a property management company.

I get it if you want to take sub to just long enough to clean it refurb and sell but as a long term investment strategy its STINKS.
