Seaport District housing prices at the end of 2018 average $2,200-plus a square foot

The average asking price for Seaport District homes as of late November was $2,238 a square foot, according to an analysis from real estate research site NeighborhoodX.

That the enclave should boast such a sky-high average should be no surprise. The Seaport is famous—or infamous, depending on your viewpoint—for hosting some of Boston’s most expensive new developments.

And a pair of those new developments—Twenty-Two Liberty and 300 Pier 4 Boulevard—drove the $2,238/foot average.

“The Seaport is an interesting market, from an analytical perspective,” Constantine Valhouli, NeighborhoodX’s research director, said over email. “Given the relatively few properties listed in the Seaport at one time, a slight shift in the listing mix could skew the average higher or lower month to month.

“Also, the prices per square foot range considerably within individual buildings. For example, at Twenty-Two Liberty, prices range from $1,216 to $2,721 a square foot, and, at 300 Pier 4, prices range from $1,695 to $3,350 a square foot.”
