Jagger Eaton is already an Olympic bronze medal winner, two-time world champion and five-time X Games medalist, and the 22-year-old pro skateboarder is also on his way to building his own financial foundation.

Eaton tells CNBC Make It that his No. 1 savings goal at the moment is to buy more income property. "It's not necessarily a hobby; it's more like a business for me," Eaton says. The Mesa, Arizona, native bought three properties in the area this year and hopes to own more in the future. "I buy homes, put about $5,000 or $6,000 into them, and then long-term rent them," he says.
