We live in a "below median price" neighborhood. Nowhere near $35k, but there are plenty of homes in the $35k-50k within a block or two (in the same neighborhood). Typical SF houses are more like $100-150k though.
Crime isn't bad. Occasionally there's a string of break ins to houses or cars, or silly high school kids doing dumb stuff kids do.
The best part is the people. Regular, ordinary people. Who mostly don't care what the Joneses are up to. We save a ton on housing and we save even more by having frugal friends in the neighborhood who enjoy frugal activities.
Edit to add: also paid cash at closing with zero closing costs. My FIL inspected the house, I pulled together half the money in cash and my parents gave me a short term loan (where I paid them a lot more interest than the bank was paying them). I did the title search (law school grad).
Closing was me meeting the real estate guy from the City (from whom I bought the house) at my new house. He gave me the keys and what little info he had on the house. I gave him a check for $105,000. After a few minutes of pleasantries, he left and I said "WTF, I just bought a house". :)
