When Im not at work I wear one of my dozens of free shirt and shorts I have left over from college basketball.

 Congrats Trevor, house hacking is an amazing way to get into the real estate game. Renting

I drove by the site for the new basketball stadium yesterday and could count 12 cranes within a half mile radius. 

Like a basketball game they know if they are up or down at any point of the game.

This will have ~100 spots with amenities like basketball, Volleyball, office, gym, dog park etcThis lot has water and electricity but needs septic.Anyone on BiggerPockets who developed RV parks in Texas that I can connect to get some advice?

Amenities include a 540-seat food hall, a daycare center, a preschool, a fitness center, an outdoor running trail, indoor volleyball courts, and outdoor basketball courts.https://austin.culturemap.com/...

Pick your game. Red

Maybe create a business card with details listed and hand them out at work, church, grocery store, kid's basketball game, etc.

Things that first came to mind:-Buy blaster boxes of Panini Prizm and Hoops Basketball at WalMart and Target (this will require me to sit in the aisle for a few days until the restocker arrives) and use the $100 to purchase 5 blasters which I can flip for $80-$100 each. 

I’m on my way out to my daughters basketball tournament but I will respond later.
