Let me simplify my answer --
If you see anything supposedly in Nambe less than $200 per sq ft-- get a new agent. Something is very wrong.
Expect to pay much more in Tesuque.
If it is not ostentatious and gated and "exclusive:", if it is less than three acres, if no one sneers at your Accord, if it doesn't have two golf courses, if the roads are paved -- it is not Las Campanas.
