Provide a small welcome basket and "in case you forgot" basket.

Some give baskets at move in.

What is the LOW HANGING FRUIT for things I can do that comparable properties may not have?

I told him that they need to dispose of TP in the closed trash waste basket.

There seems to be this focus on low hanging fruit, motivated sellers, flips and rentals.

You also should not have all of your eggs in the Airbnb basket IMO

Choose your path, remain committed, and with the backing of this incredible community, success is within reach. what would help every one is if you mentee's would go to the General Real Estate topic and in the drop down there is a top for RE success stories that's a great place to post ACTUAL results not just talking bout the program we all understand people get excited about RE but most never do anything so if these programs you mentioned actually bear fruit then post some there for everyone to see and gain experience with and so on.

Like a coffee gift card, snack basket, etc.

My “low hanging fruit” strategy is to buy a new owner occupied every year while keeping the RV to travel in parts of the year. 

Once you pick one give it a serious dedicated effort, but if it's producing no fruit after several months you can always pivot and shift.
