"Affordable, but kind of scary in the dark..."
I'm not sure about the entire span of NE 82nd, but I used to live in the area between Lake City Wy and 25th. It's definitely affordable for Seattle, and there are a lot of great schools and parks nearby. Lake City Way also has a bunch of cute restaurants and cafes near there, and one of my favorite dive bars - Cooper's. However, I would not recommend walking around there by yourself at night. Nothing actually ever happened, but it's not very well lit, and kind of scary. I guess it didn't help that the guy living next door was super creepy. As far as public transport, 25th is just down the street and offers decent bus services (except on weekends). There are a few buses that stop on 75th as well, which is walking distance.
