How much would you pay to relive your childhood but as the spoiled child of billionaire parents who gave you unlimited toys and wouldn’t let you leave the grounds? The bidding starts at $20 million—in the form of this positively bonkers Arizona estate that features a custom go-kart track, indoor golf simulator and regulation basketball floor.

The five-bedroom, 9,300-square-foot property in Gilbert used to be the “conventional” mansion of former Arizona Diamondback outfielder Andre Ethier before current owners Jeff and Sandra Sawyer added an entire portfolio of “Field of Dreams” stuff straight out of a teenage boy’s fever dream. In addition to the fully-paved kart track (and the storage/charging garage that goes with it), the 4.35-acre property has a 6,000-square-foot “man cave” with a chef’s kitchen, virtual-reality gaming station, dance studio, home gym, gun range—and top-of-the-line indoor golf simulator space. Outside, the pool area looks like it belongs at a J.W. Marriott, with its expansive sundeck, entertainment space and whirlpools.

Live here and you’ll be the forever favorite in the rich person indoor-sports decathlon—provided you can cover the $20 mil. The good news? Property taxes are “only” $27,434, and Arizona has a relatively low 2.5 percent state income tax. Gilbert doesn’t have the cache as Scottsdale, its Phoenix-area suburban sibling, but with amenities like this, who’s really leaving the house anyway?
