Clint Barton's Homestead is a farm owned by Clint Barton in Missouri. It is hinted the farm is very isolated from civilization and is off the grid. Combined with Clint's family being kept off the records, this would enable him to peacefully live there and raise his family while keeping out of the public eye.
Off the Records
When Clint Barton was recruited into S.H.I.E.L.D., Nick Fury made sure his family's existence would be a secret, setting up the farm as a secure, isolated place where they could live in safety, located in Missouri. Its inhabitants include Laura and his two children, Cooper and Lila.
Barton took the Avengers to the homestead, revealed to be the house where Barton lived with his family. Tony Stark and Steve Rogers discussed the future of the team after Wanda Maximoff showed each Avenger something about their past, future, or dark side. Later, Nick Fury visited the farm to discuss the ongoing events, and how the Avengers needed to act to achieve victory. After Ultron's defeat, Barton retired from the team and went to live with his family, now with a new family member.
