I suggest you drive by the neighborhood in the morning also in the evening to see for yourself. Talk to people while you are there ask questions. Feeling safe is really relative to the person. Also you can try the link http://www.city-data.com/ that provides information on any city. I would also ask the local police.
Speak to the owners of the house that you are interested in. I would also suggest that you make a call or visit the local Police Department and speak to them about safety and crime in that area..
Good Luck .
