You cant really break it down by zip code - a lot of areas it depends on the block. Val can tell you - travel 2 blocks one way and things can change drastically.
We dont really have any war zones IMO -- not compared to crapholes like New Orleans, the nastiness of downtown San Diego or some bad places in KC, Las Vegas etc.
Just dont buy in Hilltop, or Planview if you know what's good for you - come visit the city - walk the neighborhoods, drive them etc and you can get a feel - Sunday afternoon Saturday evening you can get a good feel for what is going on in a neighborhood. Every part of town has it's quirks like some parts you really need to check out the houses foundation/basement as there are heavier clay soils, some are full of meth heads, some at first blush may appear not too attractive but drive around and you'll find lots of older people still living there taking care of their yards, keeping everything up though the racists will say the houses aren't worth anything.
Just come experience it for a week and dive in.
Living and owning a business in our state Capital - Wichita and Sedgwick county are not perfect but they are run far far better than the corrupt bozos that control Topeka/Shawnee county. Wichita cares about it's future and what it looks like and has a police dept that will get creative to solve problems such as the homeless and panhandlers -- Topeka/Shawnee county - not so much - they just care about the wealthy zip code and a several block radius around dt where the capital building is. We look forward to moving back to Wichita or to the desert Southwest in the next few years. For now Topeka area is where we lay our heads.
