If anyone owns an indoor sports facility I would love to connect!

The area is expanding, new hospitals, new indoor water parks, reasonable good shoping (100 Outlet Stores); most developments have recreational facilities that families find attractive. 

I don't have any rehabs going on right now, but we do have a "shelter in place" order here in NY, and they warn people over 70 should particularly should stay indoors, and as I am, will stay indoors.

Our lease states no smoking anywhere on or in the property and no vaping indoors.

The existing infrastructure includes an RV park with 16 hook-ups, complemented by an impressive 81,000 square feet of diverse buildings, featuring a state-of-the-art 54,000 square foot indoor arena, a 26-stall indoor horse stable, a 40-stall covered barn, public restrooms, and a 3,500 square foot, 20-foot ceiling insulated metal building.

I'm not aware of any states that dictate that you have to allow your tenants to smoke indoors (but dbl check with your state). 

The indoor experience and outdoor experience on the property must be equally present.

Another way to solve occupancy challenges, which I strongly encourage, is adding a few more features so guests will feel less desire to leave and find comforts, such as a hot tub (with great photos, including lights on at twilight), well stock the home and make a big deal of this(especially coffee and the ease of making it), buy more indoor and also outdoor games, photograph them in use and describe them via verbiage in the listing.

Indoor pests are the responsibility of the tennent.
