Which are the best ZIP codes to buy in New Haven?

There is no single answer, because "best" depends on what a buyer is optimizing for. The three tables below rank the same 40 ZIP codes three different ways: by typical home value, by how much prices have actually moved over the past year, and by how far a home's price stretches against observed rent. A ZIP code that leads one list rarely leads all three.

Ranked by typical home value (Zillow ZHVI), highest first.
