The plan was to buy a warehouse, lay down turf and hard courts and lease the space to local schools and leagues and host tournaments.

Going to local meetups is always the first step! 

I'd check your local landlord associations to see what forms they have to get.

Why not talk to a local agent or 5 and see what they think?

For instance, Berea is a charming college town, but the combination of local taxes and less favorable price-to-rent ratios makes it less appealing for investment compared to other areas in the state.

Definitely look into local meetups, REI groups, and BP networking events to connect with like-minded investors.

I recommend you discuss and plan this in depth with a local lender who knows your market well. 

As far as i know Janesville doesnt any local restrictions on either type of rentals currently.

I also organize our local meetup in Dothan.

Any insights on rental demand, tenant turnover, or local regulations?
