In order to be successful in this market you need to be ready to jump when the right home appears. This means having a great broker working for you, having your pre-approval in hand and doing as much research ahead of time as possible.
For safety questions, you are better doing some research yourself. There is the State Patrol site where you can check for registered sex offenders and others sites that track crime statistics.
Even in the "safest area" no one can guarantee anyone else won't have something unfortunate happen, but you are wise to try to find safer areas.
