In reply to silo:
Pretty well everywhere gives good access to climbing, and good access to the surrounding cities for work etc.
The Peak isn't homogeneous though. I live between Calver and Froggatt. Just got back from bouldering at Froggatt, and can drive into the ClimbingWorks in about 20 minutes, which is great. However this is the S32 postcode which has an average house price of £427,000 according to Zoopla. There are certainly nice cottages in Places like Stoney and over toward Monyash for reasonable prices but you've got to be prepared for doer uppers.
Worth looking on the outskirts of Buxton, and then just anywhere as far as possible from a rail station, which tend to drive the price up.
