Even in a buyer’s market, there’s one locale where shoppers can count on a sizable share of million dollar homes: 93 to be exact.

That sector is downtown Charleston. Ron Henderson of Century 21 Properties Plus in Summerville highlighted historic Charleston properties in his latest newsletter.

“It is always interesting to tour the downtown historic properties live,” he says, offering an online excursion through all active listings that are more than $1 million in the “below the crosstown” area.

Based on Charleston Trident Multiple Listing Service information, the top six listings by dollar amount are 32 Legare St., $23 million; 2 Concord St., $17.5 million; 32 S. Battery St., $9,875,000; 2 Water St., $8,985,000; 19 E. Battery St., $6.9 million; and 37 King St., $6.7 million.

Each of the houses with the highest offering prices have their own stories.

The top priced property, 32 Legare, is better known as the Sword Gate House.

The South of Broad estate has seven bedrooms, a carriage house and 14,000 square feet. It went on the market in summer 2009 at the highest price ever offered for a residence in downtown Charleston. The current owner, Michael Dingman, a Wall Street merger and acquisitions veteran, and wife Betsy have several other houses.

Meanwhile, 2 Concord just went on the market this summer after extensive renovations by Blackbaud founder and Charleston Battery owner Tony Bakker and his wife Linda.

The 4,689-square-foot home is a converted former Navy building that sits on a pier in Charleston Harbor.

The structure was known for years as the “degaussing station” after the process of modifying ships to reduce their magnetic fields, which can trigger enemy mines.

Ranking third in list price, 32 S. Battery broke a record for downtown Charleston when it sold in 2003 for $5.12 million.

Fourth in order is 2 Water St. Contemporary artist John Dunnan and wife Meredith are owners of the home, which went up for sale in 2010.

A Washington, D.C., couple bought 19 E. Battery in 2009 for $5.4 million and now have it back on the market.

And Brooke Gordon, who is divorced from racing star Jeff Gordon, purchased the historic mansion at 37 King for $6.5 million less than 18 months ago.

Henderson, who markets his site at Charleston Real Estate Experts, includes a mix of items in his monthly newsletter, from housing market and economic news to the “delicious recipe” and “dumb criminal” of the month.
