My suggestion would be to visit the area that you are looking for, talk to some of your new neighbors and ask them; a lot of crimes go unreported.
You should buy in an area that you feel comfortable, not just a low priced area:
You will regret doing that every time you come home; you should be proud and feel safe in your new home.
With interest rates where they are, and special programs, you might be surprised how much home you can afford.
Good luck and may God bless
