The Epstein house came on the market in July for $21.995 million.
Mr. Glaser said that the deal is slated to close in December, after which he plans to tear the property down and replace it with a 14,000-square-foot Art Moderne home. Mr. Glaser is known for building elaborate spec mansions, such as a home on Miami’s Star Island that recently sold for about $49.5 million. He was also one of the developers of the One Thousand Museum tower designed by the late Zaha Hadid in downtown Miami.
