They make a big splash once listed, but South Florida’s priciest listings are often the most difficult to sell.

From Alan Potamkin’s Coral Gables estate – once listed for a whopping $67 million – to two spec homes on North Bay Road, these properties have been sitting pretty for more than 365 days. Check out The Real Deal’s ranking of the five biggest lingering listings in Miami-Dade.

1 Casuarina Concourse and Alan Potamkin

1 Casuarina Concourse and Alan Potamkin

1 Casuarina Concourse | Listed: May 2015 | Now asking: $47.5M

After listing the massive, 3.6-acre waterfront estate at 1 Casuarina Concourse in Gables Estates for $67 million last year, auto magnate Alan Potamkin chopped the asking price to $47.5 million in September.

Built in 2000, the nearly 21,000-square-foot, three-story home includes a main floor with both a chef’s and separate family kitchen, a formal dining room with a 1,500-bottle wine room, a family room, corporate office with private bath, children’s playroom, three powder rooms and a guest bedroom and bath, according to the listing. Additional amenities include an elevator, three fireplaces, two built-in saltwater aquariums and an aviary.

Coldwell Banker’s Jill Eber and Jill Hertzberg, who Potamkin hired to sell the property last year, are the listing agents.

Emilio and Gloria Estefan, 1 Star Island Drive, The Jills

1 Star Island Drive | Listed: February 2015 | Now asking: $37M

Gloria and Emilio Estefan’s “Nena’s Villa” first hit the market for $40 million, but was reduced earlier this year.

The 1.34-acre property at 1 Star Island Drive consists of a main house, built in 1940, and a guest house built in 1995. The main villa has 4,747 square feet, with four bedrooms and five bathrooms. The 2,661-square-foot guest house has three bedrooms and three bathrooms.

The Jills also have this listing, which offers 240 feet of bayfront and views of downtown Miami.

When they do sell the property, the Estefans won’t be far. They live in another mansion on the exclusive island retreat, at 39 Star Island Drive. “They own a beautiful property on two acres, on Star Island,” Eber said last year. “This was a guest house for them that they were not using any more.”
