Judy - an area that one person may consider "safe and secure" another person may not. So your best bet is to check out the area you are considering (if possible) at different times of the day and evening and different days of the week to see what goes on.
You can also check websites like http://www.spotcrime.info
and type the address into the box at the top right hand corner and it will give you crime statistics for the area.
I wish you the best in your property search!
