Probably exaggerating, but there's no denying that the neighborhood has a very steep appreciation curve right now.In regards to the note option, I have two buyers that have explicitly agreed to purchase the house for the 700K in whatever way we prefer, including buying the note and giving us the difference. 

I am curious how do you know things like that don’t happen twice My wife worked at a hospital in Balto city , they had armed guards in the ER .

You make the escalation clause contingent upon receiving a copy of a bona-fide, arms-length offer.

The buyer accepts the home in as-is condition at settlement unless there is an explicit agreement to the contrary.  

He made it explicitly clear that he wants to keep it straight forward and wants to get out clean otherwise he will just list it.

Our local banks will only give ARMS to investment property. 

Fixed 30 year, ARM?

I couldn't imagine why it would be cold in their when we just spent an arm and a leg on all Anderson Windows in that home.  

@Kaynea Bingham, I don't deal with HOA's, for every condo that has a HOA there are 10 that don't, several apartment complexes realize that for the traveling person Airbnb keeps the rents paid on time so some apartment complexes have explicit addendums specifying not to short term rental, others look the other way, and some welcome it. 

Which is fine IF that's what they say they're doing, but it's not.Once again AirBNB is far better with owner tools, as their Superhost criteria is explicitly spelled out and you can view your progress in detail at any time.
