Safe is relative and in the eyes of the beholder. Realtors can not address safety and crime issues. the Prince George County website offers crime stats but I would recommended if you are interested in living in the area driving around at various times of the day to see how comfortable you feel.
Ask your agent to provide you recent comps of homes sold and active listings. Plus, if you submit an offer and accepted by the seller & you are using a loan to finance. You will need an appraisal which must at least appraise for the amount requested.
