I had a condo once where we would have to call several times a week when a certain couple were beating each other regularly. It was just part of the routine of the building (sad, yes), but those statistics didn't hold for the entire neighborhood and they eventually moved out.
Does not sound like a lot of calls for service, but they would be the best to answer your question. If you want general crime information you can log into my website at http://www.joehoms.com and look at the neighborhood crime rates for the cities. If you need any assistance with your purchase, let me know.
