Lexington house prices comparable to those in Eastie, Roslindale

The average asking price for market-rate houses in Lexington right now is $387 a square foot, according to a new analysis from real estate research site NeighborhoodX.

The range that creates that average runs from $215 to $619 a foot. See the chart below.

That $387-a-foot average places Lexington somewhere between Roslindale and East Boston in Boston proper; and it is a little bit higher than the $349 a foot recently found in similarly history-soaked Concord (though the range there is wider).

One caveat to the Lexington data, per NeighborhoodX co-founder Constantine Valhouli: The analysis excluded two properties that at first glance were the most expensive per square foot—10 Paul Revere Road ($723 a square foot) and 23 Hamblen Street ($674 a foot).

"The value of these was in the land and expansion potential,” Valhouli said in an email, “so we did not consider the existing built space to justify a higher per-square-foot price than the new development at 17 Hayes Avenue.”
