Crime levels in CT are a much different animal than on the west coast. Certain parts of many towns in Connecticut and New England will have certain areas that can be described as 'sketchy'- but not teaming with criminal activity.

Hartford, New Haven & Waterbury have areas that are more dangerous. Middletown no. You might look into Portland CT- across the Connecticut river from Middletown-

Other towns to consider are West Hartford, Wethersfield, Newington, South Windsor, Glastonbury, Vernon to name a few- CT has rates in to top six states for low crime.

Yes, 3000 miles away is a leap. But these days in CT seeing more auto plates with Cali plates- you will not be alone.

I would look into Zillow, Realtor.com or other sites for rental/leases.
