We moved to Lewes in November. Had the same experience re selling our house (in Maryland) that you did. Got an offer immediately, above asking price. We moved into a rental in Ocean View (could not find a rental in or near Lewes) for six months while our house was being built in Tidewater Landing. Really like Lewes so far, except for maybe the summer traffic on Route 1!!!
We looked at Tidewater Landing, settling in Red Mill.
Appeal was both communities have Kayak Launches and we both love to kayak so that was kind of a must for us. We liked the lower outlay for amenities in Red Mill and figured we could get everything we wanted and save a little each month, drawback is we are 2 miles west of 1 instead of being east of it, which is a big deal.
I drive on the beach on the Cape, so I am not too worried about traffic, you deal with it at Five Points, but then nothing (Was born and raised in Delaware).
The funny thing is this started off and we were looking at properties in Ocean View, but didn't like it there so we came to Lewes.
Our rental is across the street from Beebe Hospital a few blocks from Fishermans Wharf. I've fished the Point at the Cape all my life so it really feels like going home.
