Mount Whistle doesn't offer up much to go on, and it would be doing you a disservice to dress up guesswork as local knowledge. What follows is genuinely all that can be said with any honesty. The one solid reference point is Cornwall, the wider authority Mount Whistle sits within, where the median house price runs to £285,000 and the crime rate is 73.6 per 1,000 people. Those figures give you a sense of the county-wide backdrop — Cornwall's prices sit close to the national median of £281,000, so this is not a place defined by extremes of wealth or hardship at the county level, and its crime rate is a reasonable middle-of-the-road figure for a largely rural, tourism-shaped part of England. Beyond that, there's nothing on Mount Whistle itself I can point to — no population figures, no school names, no station, no green space, no crime breakdown specific to the locality. I'd rather tell you that plainly than invent a character for the place. If you can get hold of a postcode for the exact street or area you're considering, it would unlock the kind of detail — schools, commute, house prices, crime by category — that actually answers whether you'd regret living there.
