I’m sorry, but so few of these urban environments are affordable with good schools. I lived in Philadelphia and we chose to leave when our son was young because the schools generally aren’t good (most don’t even have libraries, but this is a whole different topic), the green space barely exists and isn’t maintained, and I’d never feel safe with my kid taking the transit.
NYC and Boston seem like the only east coast options and those are very expensive. What other options are there on the East Coast?
