You compensation for this kind of arrangement should include compensation (for brining the land and your work effort) AND just as importantly, the boost you will acquire to your learning curve.That said, I took the liberty of using the factors you shared with Greg Dickerson and found that, as you correctly suspected the deal doesn't work based on them.

We applied for the refi with Better.com, as they're one of few lenders who will accept Airbnb income and I explained our somewhat unique arrangement to my first point of contact, including sending her photos by way of this article about our home.
