Well, it is what is is. It's a city built on the ring of fire.

Two words of advice. Do a search of the Seattle forums for "Prostitution/prostitute."
Can also include gangs/drugs/and bum/homeless as you wish. This will show show you places where people have seen that sort of activity, usually. Gangs is sort of hit or miss. Some people define "gang" as 3 Hispanic guys standing on the curb.
Second word of advice. School districts. Do a search of the Seattle forums for "Schools". You will find thread about "what are good and bad schools." These threads will (many times) have links to sites that have school scores. Good schools are in good neighborhoods. Why? Money, that's why. Bad schools....bad neighborhoods.
Not always, but a general rule of thumb. Houses/apartments cost more where the good schools are. Cops patrol there more to keep out the "bad elements." Bad people can't afford to live there. It's not a pretty portrait of life, but it's true pretty much in every major city. Find the good schools and you'll find the good neighborhoods.
I wish life was fair.

You can try apartmentratings.com. I'd imagine 1/2 the ratings are from managers of the apartments, though.
