Harvey Sanders, the former chairman and CEO of Nautica Enterprises, has a buyer for his combined unit at the Continuum South Beach, with an asking price of $22 million. If the deal closes near that figure, Sanders will have turned a $1.4 million purchase into a roughly 15-fold return over 23 years.

The 4,400-square-foot unit at 100 South Pointe Drive combines units 1906 and 1907 in the Continuum's South Tower. It includes five bedrooms, four bathrooms, a wraparound balcony, a chef's kitchen and a private foyer with direct elevator access. Sanders and his late wife, Ellen, bought the unit in 2003, a year after the oceanfront building opened.

The pending sale is the priciest condo contract signed in Miami-Dade County during the week of July 6-12, according to the Douglas Elliman Eklund-Gomes weekly luxury market report published Sunday, July 13. Carlo Dipasquale of Compass and Sonia Toth of Brown Harris Stevens hold the listing.

That week marked a jump in high-end activity across the county. Twelve luxury contracts were signed — seven single-family homes and five condos — totaling $123.9 million in asking volume, per the Eklund-Gomes report. The prior week logged nine deals worth a combined $88.9 million. The jump represents a one-third increase in deal count and a 39% rise in dollar volume.

The five condos that went under contract averaged $9.1 million in asking price and spent an average of 139 days on the market. The week's overall priciest pending deal was a single-family home at 508 West Di Lido Drive on the Venetian Islands, listed at $24.5 million.

Sanders served as president and CEO of Nautica from 1977 until VF Corporation acquired the company for approximately $585.6 million in 2003, according to SEC filings. He also served as chairman from 1993 to 2003. Miami Beach city records confirm Sanders as the owner of both units at the Continuum.

The Continuum South Tower, developed by Ian Bruce Eichner and designed by Fullerton-Diaz, was completed in 2002. The 42-story building sits on 12 acres at the southern tip of Miami Beach in the South of Fifth neighborhood, with a private beach club, pools and a four-story spa.

The deal remains under contract. No closing date has been made public.
