The house isn't really a "haunted house" sort of attraction. It's more like a tour of an older style house and a glimpse into the daily life of plantation owners from before the Civil War.
No, the house isn't haunted. The tour is really about the history of the house and the people who lived there. Very informative if you are a history buff.
Maybe, I had actually heard that it might be haunted from friends in Asheville. Here's an article from a few years ago. https://www.greenvilleonline.com/story/entertainment/2015/10/14/ghost-tour-explores-pendleton-haunts/73881186/ http://www.visitpickenscounty.com/event/1390/ghosts-of-pendleton-ashtabula-historic-house/
