I'm not sure I would get to cute trying to squeeze every time out of it now with a lease that might cause you issues in the future, but the scenario you describe is common and probably smart. 

Would the 9-year balloon concern you, knowing you'd need to refinance or pay off the balance at potentially higher market rates in the future?

Just in case.Ultimately whatever correlates with your future plans but a solid way to build long term wealth.

@John Kirtley It's definitely gone up a lot in value, but you can compare the values to Folly or Isle of Palms (Sullivans isn't really comparable) to see the future growth.

Right now they have some cute but a little wild boho looking curtains with orange, teal, gold, black.  

We'd even be happy to move them into one of our (future) properties and just let them keep all/most of their rent income as free cashflow. 

If the guest feels slighted, there is no fact checking service provided by AirBnB to confirm their claims, so it is up to you to let future guests know the level of professionalism you provide.If you are able, I would recommend editing your response to the 1-star review.

I'm looking forward to the future with everyone!

Repairs made while the property is your primary residence are not deductible, but improvements can increase your cost basis, reducing future capital gains tax when you sell.
