What the Golden Mile actually is
It is not a single urbanisation but a stretch of coastline with distinct pockets: beachside gated communities south of the road, and the hillside enclaves rising toward Sierra Blanca behind it.
The difference between the two sides is the single biggest driver of price here. Beachside buys proximity and privacy; the hillside buys view, space and light. Both are the Golden Mile, and they are not comparable in value.
