Heard about it on the expiration date of my annual contract which allowed subscriptions to submarkets. 

If you analyze 10 deals per week between now and your 10/15 extension date you’ll be able to answer your own questions.

OR one day she will mess up and miss the date! 

I asked if I could prove Year-to-Date earnings with my contracts, invoices, and bank statements, but they said underwriters always fail these exceptions for self-employed. 

Scouring the internet for answers to this question but haven't found anything definitive.

Only big category missed was internet/cable.

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.
