Drill into the crime statistics, and in a lot of cases you can see they are concentrated in a specific part of the town. Or if it’s just blended evenly across the entire town then security of the park perimeter could be put in place as a nice differentiator that would allow you to command market rents, or maybe more.
And what type of crime is it? Petty stuff or violent crimes? Call the police department and see how many calls they get per month to the neighborhood surrounding the park and how that compares to other areas of the town.
If the crime rates are high and concentrated in and around the park you might have larger reputation issues to deal with to turn it around - or alternatively you can accept it and say I am okay to run this type of business. I suspect you don’t want felons as tenants though, and violent crimes in a park can tend to drive people out.
