A lot of times when the stats are bad the Park is bad, but not always. Crime stats should never be the reason you turn down a deal. If anything it should make you do some extra diligence and will ultimately support the other reasons why the deal is bad.
Last year for a 26 pad park in Kansas I was doing my on-site diligence. Before arriving I saw lots of crime stats within 5 to 10 blocks of the property - not overwhelming though it was mostly petty things. 90% of the homes were all derelict and tenants jobless on government assistance. Came back from lunch and three cops were putting a tenant in the back of a cruiser who had an outstanding warrant. Property manager was separately a sex offender. 100K in deferred infrastructure maintenance. 65 feral cats all over the property and tenants feeding them. A couple of the homes on Google Street view looked bad, but these photos were 3-5 years old and not using their new HD cameras yet. They were in much worse shape than expected.
It was a sad story too because it was a nice little town and the test ad results were great, but the Seller misrepresented the property's condition and would not budge on price after the site visit. As of a few months back it was still for sale.
