The Option has a definitive closing date and a fixed price in the near term, its not a series of payments toward a 30 year ultimate ownership.

I told her I would not give her a date until the current person moved out and I looked at the house carefully and had it fixed. or at least scheduled to be fixed. 

You can use several different payment apps now available, management company or agent for payments as well. 

-Late Charge: $120 if payment not received by the due date, then an addition $50 per day until payment is received.

If someone books on VRBO or on a direct website then their calendar sync will block the dates on AirBNB, and I would then guess MashVisor will see it as a booking.If that's the case then if anything it probably does the opposite and over-counts it rather under since it is probably counting owner stays as bookings.

You should make sure that probate is up to date on the utilities when you close for the house.

@Alex Reamon Get the water heaters back on, lock the door and tell the tenant to provide you with their move out date.

I assumed 25% down, $6K property tax, 4.125% conventional 25 year commercial loan, $20K fixes for bringing one unit up to date and fixing minor issues, and 8-10% for variable expenses. 

If going the rental route, consider joining CAA (California Apartment Association) for forms and up to date information regarding landlord/tenant laws.
