Jacquse is correct, this is something licensed realtors can not speak upon. However, the good news is that New Haven has a great website to help home buyers make that decision on their own based on recent police incidents. Here's the site: http://www.newhavencrimelog.org/cl/streets/
If you have any other questions, please feel free to ask me. I know the area very well and would be happy to show you some properties there.
