What amount or type of crime would be acceptable or unacceptable to someone is impossible to determine by another individual. We all have different tolerances. I feel that prospective buyers should drive by a property that they are interested several times, at different times of day.
Believe it or not, the best person or agency to talk to about crime statistics in Louisville, is the Louisville Metro Police Department (502) 574-7111 or (502) 574-2111. Just contact them and give them the property address you are interested in.
