The gentrification of Brooklyn is oh so very real. And just in case you wanted to see where it was happening, well, Property Shark has a map for you. It looks almost exactly the way you expect it to.
What is really interesting in the map (which covers property prices change between 2004 and 2012), however, is just how localized things are. While some neighborhoods are seeing cah-razy growth (Williamsburg, Lefferts Garden, Gowanus, Fort Greene) others are really, really not. Head a bit deeper in and you see some serious declines in places you might expect (poor Cypress Hills) and some you might not (what's up with Fort Hamilton/Bay Ridge?).
Now, for a really fun time, compare this map to where people like to complain about rats...
