A bad area is really a personal opinion and not one a real estate agent can or should answer for you. It is really the buyers responsibility to do the due diligence and make the decision on what they are comfortable with.
What I would suggest is two things. One if you find a property you like visit this website and type in the zip code. It will give you all the data for the area. http://www.city-data.com/. You can also look up the address on this site as well http://offender.fdle.state.fl.us/offender/homepage.do;jsessionid=v32E628HpBxfbS65e97+lQ__
Second I also suggest putting the address into google earth. You can get right down to the street level and get a feel for the neighborhood, what is around it etc. Then armed with the information you can make an personal educated decision. If you are local I would suggest driving the area either during the and also at night to get a feel as well.
I hope this helps. If you need anything else or have other questions feel free to call me, happy to help. My information is below.
