Dude

Welcome to the forum ...
Many people take the step to move to some area of Kernow, Hastings isn't a bad place but there is a large element round there that's not so nice but you get that anywhere.
Just make sure you have enough cash set aside as you'll be expected to pay a deposit & a month up front in rent so if you have a job to go straight into then all the better - especially if you have a family to support.
Use the search facility on this forum using key words like 'moving' to check other threads etc.
If your moving to Newquay itself then avoid Pentire as prices are very high (this is where I come from) but further up or down the coast is cheaper like Porth or as already mentioned Perranporth ... thought they can be a little remote without your own transport.
Though its off the coast places like Truro, Redruth are also a good move & Wadebridge too.
