A 54,570-square-foot estate in Manalapan, Florida, is set to become the most expensive home ever sold in the US, with an astounding $285 million price tag. The newly listed mega mansion boasts 8 bedrooms, 16 bathroom, and recreational amenities such as a bowling alley, golf simulator, and car museum. If sold at asking price, it will shatter the previous record set by Ken Griffin's $238m NYC penthouse.
