No, there are no bad parts.

Stratford is next door and is FFC, but the taxes are much higher than in Milford and it’s arguably a more blue collar town. Lord$hip is on the water and beautiful, and there are great neighborhoods in the north end (check out Beaver Dam area). Everything in between is kind of meh, and parts of the south end (success village) suck. That said, I would not hesitate if you can afford one of its “nice” neighborhoods.

Then there’s Shelton and Trumbull if you want a more rural lifestyle.

Fairfield is beautiful if you can afford it.
