My friend lives up in the Wilmington area, just moved north due to a job change. He used to live in Bear, DE. Wilmington and the surrounding suburbs can be nice, but be careful of where you look if you consider downtown Wilmington. There can be some not so nice areas there (just like any city). But the location to I-95 from Wilmington is nice, it'll get you to Philly in less than 45 mins, and down to Baltimore in about an hour or so. And it'll get you to the beaches in about an hour also. Nice location if you want to get around to other places. And the cost of living isn't too expensive, if I recall correctly.
I can ask my friend about suggested areas if you'd like, what city is the job going to be in?
