The ADU does not have a private entrance; you enter on the side of the SFH and they both share the same back yard.It is at the top of our budget already and needs potential mini-split HVAC added to it to bring highest Air Bnb value.

I lease to some Air BnB'ers.

These are places that would never be painted, and the stinky salts in the urine are still active due to the humidity in the air.  

A lot of Delta Air Lines employees opt to live south of the city for easy access & less traffic to reach the airport.

Make sure you have an air-tight lease and also a house rules or house expectations.Has someone been renting in the other side and you are just renting your side? 

:However, I wonder if we will have more dual agency type transactions. 

As @Daniel Sperling said, either get a standard contract that you can edit from a realtor you know or pay a local attorney to draw you up an air-tight contract that you can re-use once they know your goals - direct to seller, wholesaler, etc.The worst thing you can do is show up with a half-page doc for a seller.

Tenants used the propane for 9 years, then we decided to switch to heat pump with central air and stopped using the propane.
