There is work in rehoboth, but its not a ton. Commercial work is slow and has been for over a year now. they overbuilt and its just now catching up.
There is residential remodeling work out there, but you gotta find it cause theres enough guys doing work to snatch it up quick. New construction is all tract homes, mostly Schnell (how ever its spelled) so to be a sub you have to be super fast and cheap. quality is 2nd tier as long as it will look good enough with paint on it.
The other thing is the pay scale less down there, and the cost to live at the beach is really high so you have to live up in the farm land and drive it.
Up here above the canal its about the same work wise, there is some commercial fit out work and home remodeling. New houses is pretty slow and commercial jobs are pretty dead right now. commercial always lags behind residential so they are just now getting into the period residential had 2 years ago.
New homes are also all tract for toll brothers or ryan homes. there is not much of it.
The university has a huge boom the past 3 years for housing but that is slowing down already. They are all rental town houses, so its the same deal, who ever can do it the cheapest wins.
The university itself was busy until last year when it just up and stopped doing projects. Things are improving in the residential market, but it will be a little bit before the commercial catches back up.
As far as living, its pretty nice here. The state is 3 counties, Newcastle, Kent, and Sussex. NC is where most of us live, and Sussex is the beach basicly. The nickname is Slower Lower, and there is a line you cross going from dover to the beach where it becomes southern, its more relaxed and slower. The summers at the beach are nuts cause everyone from DC and up north has vacation homes there and are there every weekend. If you go, check out Dewey Beach. its a small skinny patch of land between the ocean and bay, and its awesome. very chill laid back attitude with plenty of bars and stuff, and all with in walking distance.
good luck with everything!
