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. 

-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.

Hello fellow BiggerPockets Investors,My name is Cat and I am EXCITED to be here!

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.
