My family lived/live in this area of Devon. My parents were in several locations around South Brent, Ivybridge and Ashburton. And my sister still lives there out in the wilds of the moor.
Exmouth was my parents' home - they moved there just after I left 6th form for university; and I knew the area well, before that as my Grandmother lived in Lympstone and we spent all our holidays there as children.
The downside of these lovely places is the A38 - the huge dual carriageway that cuts the county in two, right by the places you are considering. When I used to be driven down there in my teenage brother's open top car, the road was fairly quiet and tolerable. Now it is a dangerous nightmare in my book; and a huge inconvenience to locals, some of whom need to join it, leave it at the next junction, cross it over a bridge, and rejoin to go back the other way to get to their local shops. I hate that road! There are some seriously dangerous entry and exit points and places where you can turn into a garage, but leaving it is in a hazardous place and there have been several accidents.
I would not live down there simply because of this dangerous road that cuts like a knife through the lovely countryside, and can be heard as a distant hum wherever you are - it used to be such a quiet place.
