In most US cities, the walkable parts that aren't heavily crime-ridden and distressed still have pretty bad schools (because they're just pockets here and there among the really poor parts) so you'll be adding the cost of private school (and hassle/cost of transportation to it, if it's a day school) to the already-high costs of housing.

There are a very-few cities with walkable areas of the actual city (not a walkable 'burb) that buck this trend, but it's the overwhelming norm. If you have money, have kids, and live in the city, the kids go to private school.

(Yes, I know, parts of NYC are a huge exception to this, I'm just saying, your list of potential target cities with this scheme is short unless you're planning to also pay for private school, in which case a whole bunch of cities open up)
