Warren Buffett could see a big return if his Laguna Beach, California, home sells for close to its $11 million asking price— but it seems to be lacking an interested buyer.

“It’s now been on the market for about five months longer than the median listing time for similarly priced homes in the same ZIP code,” reports Bloomberg’s Noah Buhayar, citing data from Redfin.

Buffett has owned the home since 1971, when he purchased it for $150,000. That’s about $934,000 in today’s dollars. He’s since renovated the place, which has six bedrooms and more than 3,500 square feet of living space.

The billionaire investor had primarily used it as a beach retreat for his family, but they reportedly hadn’t used it much since his first wife, Susan, died in 2004.
