West Devon, around Tavistock, just north of Plymouth is lovely, and quite naice. South Hams is beautiful, but ££££.
Plymouth is an acquired taste, but was the fastest rising UK property market in 2025. It is still cheapish, for its wonderful coastal location, with good and poor/decent housing stock, but the city is gritty. It has some of the most deprived wards in England, and is currently being used for migrant dispersal accommodation. Plus it is home to the Marines.
The road traffic network is modern, and being improved; the hospital is over-stretched but very well run. Schools vary, but the grammar schools remain selective, just not super-selective.
I actually like Plymouth and its people, but I live about 6 miles north of it in rural charm. The theatre gets West End pre-shows, and the restaurants are as varied as you'd expect in a merchant port. There's everything from Japanese (four good Japanese restaurants) to Indian, Korean to haute cuisine. Great ingredients are landed in the fish market every day and there is a massive artisan horticulture hinterland in the city's perimeter. And almost half of Britain's naval history started here. The Museum is good, there's a very lively art scene, and it's three hours to London by train.
If the authorities would find the money to reopen the airport and fund the avionics needed to land a plane in low cloud, the place would be Boomtown.
