Barkley, who was the second overall pick of the 2018 NFL Draft, posted a photo on Instagram of himself standing in front of a house with a "sold" sign on the front lawn.
"Something I promised my parents, ever since I was a young kid. Finally be able to achieve that goal is the most amazing feeling," the 21-year-old wrote in his caption. "Every kid out there that has a dream continue to keep your head down and work your butt off, great things will come along the way."
Per TMZ, the 3,355-square foot house features four bedrooms and three bathrooms, and is approximately 90 minutes from MetLife Stadium in East Rutherford, N.J.
Before the draft, Barkley said his first major purchase as a pro athlete would be a house for his parents.
"The first big thing I'm going to buy is my mom a house. My parents are everything to me -- and all the sacrifices they've made -- I wouldn't be the man I am today without those two -- my mom and my father," Barkley said, via 247sports.com. "So, definitely going to buy those two a house that they can call home and not have to worry about anything."
Barkley's parents relocated from the Bronx to the Lehigh Valley area in Pennsylvania so the family could grow up in a safer environment.
The 6-foot-3, 233-pound Barkley later made himself at home at Penn State, rushing 217 times for 1,271 yards and 18 touchdowns last season with the Nittany Lions. He also caught 54 passes for 632 yards and two scores, as well as returning two kickoffs for touchdowns.
Barkley lit up the 2018 NFL Combine with a spectacular workout, registering a 4.40 40-yard dash, a 41-inch vertical jump and 29 reps on the bench press.
