Luxury homes in the D.C. region were snapped up at a brisk pace in 2015. Houses in the $5 million-and-above price range tend to linger on the market, sometimes for years. But in 2015, six of the top 10 most expensive homes sold less than a year after they were listed.

A Cleveland Park home lasted just four months on the market before it was bought for $6.3 million. The most expensive single-family residence sold in 2015, Fessenden House at $18 million, was gone in eight months. That may not seem fast considering half the homes sold in the District in November were under contract in less than two weeks. But at the high-end price range, selling a multimillion-dollar home in a matter of months is speedy.

Not every luxury home sold quickly. Riverview Manor in McLean needed three years and five price cuts before selling for $8.3 million. A Federal home on Cox’s Row in Georgetown languished on the market for five years.

“These large properties are not easy to price,” said Nancy Itteilag of Long & Foster, who was one of the listing agents on the Fessenden House. “The hardest part of valuing a property is that every one of these is a custom home. There aren’t two alike.”

The rapid pace of sales is just one indication that the luxury housing market continues to thrive in the D.C. area. For the first time since 2010, three homes sold for more than $10 million in one year.

“The weight of the market is still $4 million to $5 million for the upper end,” said Washington Fine Properties’ Nancy Taylor Bubes, who represented the sellers in three of the top 10 sales. “Five million was a big marker up until last year. This does move the needle some, which is very exciting for the whole market.”

Many of the buyers in this price range have multiple houses. Take Adrienne Arsht, who is selling her Massachusetts Avenue Heights house after buying another in the neighborhood. The philanthropist and member of the Kennedy Center’s board of trustees also has residences in New York and Miami.

“We’ve become a destination city,” Itteilag said. “People want a Washington home even if it’s not their primary residence.”

Georgetown continues to be the most-sought-after location in the luxury market. The tony neighborhood had 20 sales of $3 million or higher. Kalorama was second with 10 sales of $3 million-plus. Massachusetts Avenue Heights had five, while Cleveland Park and Forest Hills each had four. The West End had three.

In Maryland, Bethesda and Chevy Chase (Zip code 20815) had seven sales at $3 million or above. In Virginia, Old Town Alexandria (Zip code 22314) and McLean (Zip code 22101) each had five sales of $3 million or higher.

A penthouse at the Residences at the Ritz-Carlton in the West End that sold for $6.05 million was the most expensive condo sale in the District since 2013 and the highest price paid for a condo not located near the Potomac River.

Because the list was compiled with the help of MRIS, only sales that were recorded in the Rockville-based multiple listing service by Dec. 31 were included. Private, multifamily residential and commercial sales did not make the list.

The two historic mansions in Kalorama housed the Textile Museum for nearly 90 years until the museum moved to George Washington University’s campus. In 1912, Textile Museum founder George Hewitt Myers hired John Russell Pope, architect of the Jefferson Memorial, to design his home at 2320 S St. A decade later, Myers bought the adjacent mansion, which was designed by architect Waddy Butler Wood. Both properties are on the National Register of Historic Places.

The neoclassical limestone mansion in the Forest Hills neighborhood was inspired by the works of 18th-century Scottish architects Robert and James Adam, particularly Dumfries House. The 1994 house was designed by Leon Chatelain and took two years to build. It was constructed for Samuel Lehrman, a grandson of one of the founders of the supermarket chain Giant Foods. Everything produced for the house was cast in plaster first. From the banister on the staircase to the molding around the doors, a model was made before the final product was produced to allow for refinements to the design.
