65 Gregory, Cos Cob, asking $2.375 million. I haven’t seen it, but the highest price achieved so far on this street was $1.825, back in 2011. Everything else has sold way south of there, but this is new(ish) construction and a different class. Still, there’s something about being the far most expensive house on a street that gives pause. Worth looking at, certainly, because $2.4 in Cos Cob should go a lot farther than it does in other areas.
