Just ten days it took builders to sell a $19.5 million mansion in Miami Beach

The builders offered contemporary style, 11,500 square feet, five bedrooms, two staff quarters, gym, pool, four-car garage and chic design featuring raw woods, clean lines and organic fibers—a winning combination for a buyer willing to pay $1,694 per square foot.

Builders Jarrett and Sean Posner and Todd Glaser collaborated with Paulo Bacchi of the Brazilian furniture brand Artefacto to create a showpiece manse on Pine Tree Drive in Miami Beach.

A multimillion-dollar gamble paid off quickly for investors whose newly built luxury estate was snapped up in 10 days.

They built the property on spec—with no buyer contract—but closed on a $19.48 million sale days after it hit the market.

The builders used a limited liability company to make the trade with buyer Lisa A. Schneider, trustee of the Pine Tree Irrevocable Trust, according to a deed recorded Dec. 23 in Maimi-Dade County.
