The beaches at Walton and Frinton are really nice and there are some cracking properties in Frinton. It’s not cheap though.If you want somewhere adjacent to nice sandy beaches, and not totally fallen off the map (though it is a bit), then the Essex beaches of Walton-on-the-naze/Frinton-on-sea would be a good places to consider (especially if you can't quite stomach Clacton).
