I suppose it depends what you're used to, but walking to gigs or using public transport is highly unlikely.
Both my bands straddle the Devon/Cornwall border and when we were gigging we regularly travelled the entire length of Cornwall and up to Exeter, Torquay, Teignmouth, Exmouth, etc.
Exeter was always a good crowd, my avatar is in The Cavern in Exeter.
From the amount you've said you'll to gig you should be fine, but expect to do some travelling to Torquay, Plymouth to pull in the gigs as well as Exeter.
I'm happy to travel but we had an enquiry last week asking how much to gig in Skegness, erm yeah, won't be happening. 😄
Good luck if you choose to move.
