Building an optimal AirBnB house/structure?

[Peter Knepper]

My wife and I are just getting started and excited about real estate and trying to plan out what our first move is. We live in Grand Junction, Colorado and housing prices are very high, so buying a profitable rental here at the moment is going extremely difficult. We live on 3 acres in "wine and peach country", so we came up with the idea of building an accessory dwelling unit (ADU) on the property to use as an AirBNB. Running the, numbers, it appears like it will cash flow well.

My question is, since we are building it from scratch for this purpose, how would you go about designing it for maximum profitability?
