There is nowhere in the Bronx that is affordable and even remotely decent.
Sure, you can find something for 350K in the South Bronx and dodge bullets and bums if that is your fancy.
Brooklyn is high priced everywhere now.
Carnesie, Coney Island, Brighton Beach, edge of Bed-Stuy, etc. etc. are still within reach of many. No, you don't get to live someplace quaint and safe like The Heights, the Slope, Cobble Hill etc. But fortune favors the bold.
In any event, my sense is that you don't see yourself in NYC in 20 or 30 years. So why bother?
