OK, I live 10 miles from Launceston. Go there pretty often. What exactly do you want to know about it??? There is a good sports centre with excellent baby swimming lessons, a good choice of schools, a minor injuries unit (very useful if you have little ones) and even an Argos (wow!!!) We don't get many chain stores down this way - the nearest macdonalds etc would be about 25 miles I think - poss more. There are loads of family friendly attractions on your doorstep and the beach at Bude is about 30 mins drive (so you can get there before the emmets tourists)
There are certain places where the locals ARE unfriendly to incomers (only being honest, this is from my own experience - sorry). There are ways round it though. I don't think you'd have much a problem in Truro as it's full of 'incomers' these days. Launceston doesn't seem that bad either, yet in a village a few miles away from it, is can be a very different story.
Are you thinking of living in Launceston itself or just outside?
Have you been to launceston???? It Blo**y hilly . You are right next to the A30 and people living there commute on a daily basis to Plymouth etc. It is considered a very good base for travelling around devon and cornwall. Whereever you live in the counties you will be likely to be doing more longer journeys than you are maybe used to so an economical car is useful
Don't let what I said about the 'unfriendliness' put you off. I would not live anywhere else - my children love it here. As soon as we leave Devon everything seems so industrial! The traffic down here is nothing compared to when we leave the area - even in the high tourist season because the locals know the back roads .
If you want any more info let me know
btw - you will get a pretty nice house in or around Launceston for that budget - what number of bedrooms do you need? My place has 3 beds plus 330' long garden, several good size outhouses and a shippon and is worth less than that.
