A penthouse at One Dalton has sold for $30 million. The unit on the 61st floor has six bedrooms, seven baths and phenomenal views.

Both the buyer and seller are not known.

Despite fears of the recently passed “Millionaire’s Tax”, high mortgage rates and global instability, the luxury housing market may be on a record setting pace, according to Kevin Ahearn of Douglass Elliman Real Estate who has tracked the city’s housing market for decades.

“There are three [high-end] new buildings, Raffles, St. Regis and Winthrop Center that have generating about $508 million in closings so far this year with more to come.”

According to Ahearn, high-end buyers are empty nesters from Boston’s suburbs or wealthy individuals who believe that real estate will produce better returns than debt and equity investments. “Cash sales range from 21 to 43% depending on the building.

One previous group of condo buyers is no longer a factor as foreigners have stopped buying in the area.
