Clint Barton's Homestead is a farmhouse owned by Clint Barton in Missouri. The residence is implied to be very isolated from civilization and located off-the-grid. Combined with Barton's family being kept off the records, this enables him and his wife, Laura Barton, to peacefully live and raise their children here 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 kept secret, setting up the farmhouse as a secure, isolated place where they could live in safety, located in Missouri. Its inhabitants include Barton, his wife Laura, and his two children, Cooper and Lila. The only other person to know of this arrangement was Barton's partner and best friend, Natasha Romanoff.
After the Avengers' loss to Ultron, nightmares from Scarlet Witch, and an outbreak of the Hulk, Clint Barton decided to take the team to his home, where they could lay low and collect themselves. Clint landed the Quinjet outside the house, which the team thought was a safe house, as they made their way towards it.
When they entered, they discovered Clint being greeted by Laura, who was revealed as his wife that they were not aware of. Following this surprise, Cooper and Lila appeared, and Clint hugged his family, while everyone but Natasha Romanoff stood there, shocked. As Clint and Romanoff reunited with the family, Thor exited the house and went off to go find answers for the visions he saw earlier. The Avengers then got changed and each went and did their own thing.
Clint talked with his wife, informing her of what had been happening with the team and Ultron, having been the only one not to be affected by Scarlet Witch. They also discussed Romanoff and Bruce Banner's relationship, as well as Clint's place on the Avengers. Clint then went to do some woodworking with his children outside.
As Banner got out of the shower, he found Romanoff waiting in the other room. The two revealed to each other their darkness within them, both seeing themselves as monsters. They then discussed being together and leaving everything behind. However, Banner explained to Romanoff that he could not have a normal life, not like Clint, as he gestured to the home environment.
Meanwhile, Tony Stark and Steve Rogers went to chop wood outside as they recovered, where they discussed the future of the team after Scarlet Witch showed them something about their past, future, or dark side. When they started arguing, they were interrupted by Laura who asked if Stark could fix their tractor, so he left Rogers to help her.
Stark entered the barn, but was greeted by Fury, who had been called by Maria Hill. Fury and Stark discussed the latter's actions in creating artificial intelligence. Stark revealed how he was shown the death of the Avengers and how he would be responsible for it.
That night, Fury talked with the Avengers, discussing the ongoing events, and how the Avengers needed to act to achieve victory. They were able to realize Ultron's plan, and the team headed out to stop him. Clint promised Laura that this would be his final mission, and the flew away in the Quinjet.
After Ultron's defeat, Barton retired from the Avengers and went to be with his family, now with a new member being born shortly after. When Clint went to assist Captain America in 2016 and was imprisoned and eventually freed from the Raft, Clint decided to make a deal with the government to be put under house arrest, so he could be with his family, rather than a prison.
In 2018, one day, the Barton family decided to have a picnic outside their home, as Clint was still under house arrest. As Laura prepared their lunch, Cooper and Nathaniel played catch while Clint trained Lila in archery. However, Clint's family disintegrated from the Snap, leaving him alone at the house.
Testing Time Travel
Five years later, Clint volunteered to test time travel via the Quantum Realm. He arrived in the barn at his homestead in an alternate 2018 timeline. Clint made his way to the house, where he got emotional at being back there. He then overheard Lila arguing with Cooper, prompting him to try and see his daughter again. However, he was brought back to the present seconds before he could.
After the Blip, Clint's family were restored to life. Shortly afterwards, Clint returned home in a Quinjet where he was happily greeted by his children who hugged him on arrival. Clint then embraced Laura, happy to be reunited again.
