I've lived here 30 years and surprised to hear that. It possibly depends on the area and a report gets logged for every call, many which are minor. I don't believe serious crime is a problem here at all but more of a "look for trouble and you will find trouble" problem. Almost everyone knows each other here.
We recently bought a house near Stone st in Deland off of W Euclid ave. All the neighbors are nice and there are a lot of families with children around this area. We are able to walk the dog near the historic homes and we are very comfortable with our choice. I would recommend Deland. Hope this helps you.
Real estate agents and Realtors are responsible for letting a buyer know that it is THEY who need to do the due diligence we can supply you with the river info or the crime stat contact but since much is subject to interpetation it is best to hear it with your own ears and judge it as how it will relate or affect you.
Some cities have more crime than they report to insure tourists or habitation and that is just how it is.
