My husband grew up in Canarsie, and we have lived in Baltimore for nearly 20 years (and raised a child here) so he is not up to date on the current vibe in Flatbush, but for similar housing stock and a Jewish turned black now become more mixed neighborhood with architecturally appealing brownstones I would add reservoir hill to your list. Druid hill park is a great asset, but the neighborhood is lacking in "walk to amenities (coffee shops, restaurants, grocery, etc).

For example this one: https://www.redfin.com/MD/Baltimore/2430-Eutaw-Pl-21217/home/10866259

On a two (even public interest) lawyer salary I would also consider Roland Park, Guilford and Tuscany Canterburry. Tuscany Canterberry is all row homes, Roland Park and Guilford have large row homes at the edges (they were built to keep the riff raff out).

I find that those that choose to live in the city are pretty committed to the city and making it better and therefore very neighborly. I know that our block really looks out for each other and my impression is that is true in many parts of the city.
