My wife and I will both be over 65 by the time we intend to move, so hopefully we will have few problems in transferring our healthcare entitlement.
As far as location is concerned, we are looking at a few inland villages in the Granada Province, away from the tourist hotspots. Neither of us smoke, are particularly big drinkers or have expensive hobbies. Other than the cost of the property itself, we have budgetted for buying a new car, moving fees, buying taxes and charges etc... and a small amount for 'unseen circumstances', but this will leave us with only a small amount to subsidise our pension.
It has long been our dream to spend a few years in Spain, but we would rather not come at all if it means living on the breadline.
