Exclusive | Oil trader Mark Fisher re-lists $78M Miami mansion

A $78 million waterfront mansion in Bal Harbour is the latest trophy property to hit Miami’s booming luxury market, The Post has learned. 

This isn’t the glassy home’s first appearance on the market. It briefly listed in November 2024 for the same price and again in March, according to Realtor.com records — but it returns in good company.

Despite trouble in the lower price tiers, South Florida’s luxury market is humming along with eight- and nine-figure listings, from a $200 million partly finished home in the ultra-exclusive Indian Creek to a $185 million potential teardown in Palm Beach. Those both hit the market in the last week.

This pricey pad’s owner, Mark Fisher, is the founder of proprietary trading firm MBF Trading.

Fisher made his fortune trading energy commodities, particularly oil and natural gas. He’s now trading his custom-built trophy property for an even larger family compound nearby.

Specifically, Fisher told The Post, his family plans to move to a much larger property about 40 minutes west of this property, on “almost 15 acres.”

Jill and Danny Hertzberg of Coldwell Banker Realty represent the Bal Bay Drive listing.

Fisher and his family built the bayside mansion in 2017. The roughly 1-acre lot cost Fisher $9 million to snap up in 2013. At that time, the property hosted a small multifamily building. Fisher tore it down, but retained the lot’s generous zoning. 

The move allowed Fisher to build one of the tallest homes in Bal Harbor.

“We were able to build higher,” Fisher told The Post. “So we have a third floor that has a pretty incredible gym, home office and game room, without taking away so much space from the house.”

The rest of the residence isn’t lacking in space. The 10,729-square-foot interiors are set off by a 42-foot-high foyer. Its three floors include nine bedrooms and 11 full baths. 

Several of the contemporary living spaces are lined with retractable glass walls, and the amenities-filled rooftop terrace offers 360-degree views of Biscayne Bay and Bal Harbor. 

The affluent village on the northern tip of Miami Beach is largely made up of gated communities, including Fisher’s. A little more than 3,000 residents reside in Bal Harbour, and enjoy its open-air luxury mall and large yacht marina. Brazilian soccer star Neymar snapped up a $26 million home there last October, the Wall Street Journal reported. 

“I think people recognized how special it is and how convenient it is,” Fisher said. “I think that’s what’s made a lot of people tear down houses and build pretty extraordinary residences.”

Bal Harbor’s median listing price currently sits at $2.8 million, according to Realtor.com data, with the typical home spending about 121 days on the market. 

Fisher and his family filled their custom-built home with luxury perks, including a rooftop putting green, a home theater, a basketball court, a Jacuzzi and two heated saltwater pools.

“It’s a thriving gated community, and I live a hundred yards from the beach, so what could be better than that?” Fisher said of the home.
