Professional basketball player here who has a ton of time in the offseason.

Maybe you could add a wine cellar downstairs or a basketball court in the backyard while your taking their requests to renovate the property .

A landlord here in Houston told my neighbor to take down the kids basketball hoop off his property.  

Pretty cool with the American Ninja Warrior stuff!

Toss in his retirement, whatever his disability is (which IS tax free) and the fact that his fiancé is working full time and even without his second BAH payment and his employment rent should be covered assuming this is an important goal for the two of them.If I sound jaded it's only because I once rented to a young (early 30's) veteran who was not only 100 percent service connected but also managed to draw social security AND had the Wound Warrior Project fork over his security deposit AND first months rent for my SFH. 

Looking back the harbor freight tools have served me just as well but I am more of a weekend/ after work warrior.

@Jorge Rios I love NW Arkansas, I went to school in Siloam Springs (most people won't be able to appreciate that, but I know you will :)) and my brother actually lived in Centerton for 4 years while he was a basketball coach @ Bentonville High School.

@Abraham AndersonMaybe consider a couple of soccer goals, or although more expensive a basketball court.

These resorts have amenities guests love, pools, spas, clubhouses, water slides, mini movie theaters, tiki bars, tennis, beach volleyball, basketball, games arcades, playgrounds and some even have restaurants.

If a 'spandex warrior' has ever ran your son off the bridge shoulder cursing because he was in a hurry and getting his cardio on, you wouldn't consider it as happy experience either.
