Tell them they can break the lease (sounds like it is medium term lease) without penalty. 

For leases you write for your own buildings need give tenants no agency disclosures. 

I'm currently renting to a section 8 tenant in NYC and I've decided I won't be renewing the lease once it expires next summer.

I engage in long-term residential rentals, triple net leases, and short-term rentals, each of which has its own advantages and disadvantages.

Traditional lenders in this industry won't fund you on a purchase of a SFH that has leases for rooms and the building will need to be in your LLC name which means a primary bank won't lend you either cause of that and cause of your employment status.You have a real chance to start. 

You would be entering an estimate for each item. 

Not easy to find cleaning companies that are trustworthy and can deliver the fast turnaround that you need to be able to re-lease the cabin same day.

You need to read the lease (if he's been there for 20 years there may not be one).

I'm not sure the premium vs the basic version (I only have premium) but for any property, I can itemize the purchase price, current value, tag the associated mortgage, my assumption on appreciation, its rental income, all of its expenses (including taxes, yearly mainteance, capex, insurance, HOA, property management, depreciation and other), its estimated sale timing/and fees. 

I have a new tenant and we are working on a lease, the rehab from the old tenant and the new TI will be $500,000.
