When my family looked across the US for somewhere to move from Northern California, we chose Santa Fe. Why? A smallish town (70,000), real climates but not too harsh, all the culture we could handle, a diverse population, close to the mountains, progressive politics.... We've been here for 6 years, and really enjoy it. The town has delivered on most of its promises. And it even has a Trader Joe's now!
I'm a realtor here now - my wife teaches at an elementary school. The housing market here is different to the rest of NM - more expensive, with median price of $425,000, although I've sold nice condos to people for less than $200k. So it's not a trivial decision. But, for us, the right one.
