The only thing as Realtors we can really tell you is to check public websites for crime rates. City-Data, police and others.
Another thing to know if buying investments are point-of-sale inspections for Euclid. Not sure if you're aware of them or not. I'm sure you are since you lived there.
Wish I could shed more light on your concerns/question but it's not something we'd be able to really discuss.
