Sheriff’s deputies said Brent Nicholson, who lived at the home in Pageland, South Carolina, has been arrested and charged with possession of stolen property.
Ammunition, around 150 chainsaws and taxidermy supplies were also discovered, they added.
The guns reportedly filled one 40ft-long truck and the ammunition filled another as they were taken away.
The weapons were mostly shotguns and hunting rifles, and officials said it appeared Nicholson was hoarding them after other people had stolen them for him.
Hundreds more guns were discovered at an off-licence that he runs with his father, according to Chesterfield County Sheriff Jay Brooks.
Deputies have found no evidence that Nicholson ever sold any of the guns, according to WBTV.
Sheriff Brooks said: “There’s like 150 chainsaws, probably 250 to 300 taxidermy mounts, somewhere between 7,000 and 10,000 stolen weapons.”
When asked what Nicholson, 51, was allegedly doing with so many guns, Sheriff Brooks said he “looks like a gun hoarder, to be honest with you”.
He added: “None of us have ever seen anything anywhere close to this. No telling how many break-ins this will help wrap up.”
The sheriff told the Charlotte Observer newspaper: “There were so many guns we quit counting after a while.”
The guns may have been taken from North Carolina homes and hunting clubs. Nicholson’s home is near the state’s border.
He was arrested and charged with trafficking opium and heroin earlier in the week in Union County, WBTV reported.
Deputies went to serve him with a subpoena on Friday and noticed what appeared to be stolen chainsaws in his front yard.
They then got a search warrant and went back to the house and found thousands of guns.
Authorities plan to send 20 agents to help process the stash and determine what has been stolen.
