Puerto Vallarta and Nayarit are neither the cheapest retirement choice in the world nor the cheapest option within Mexico. You aren’t likely to find it a bargain compared with the cost of living Stateside… unless you compare it (as you should) with the cost of living in top Pacific coast locales north of the Rio Grande. Puerto Vallarta could be called a bargain compared with the cost of living in Newport Beach, for example. And, in this case, that comparison wouldn’t be extreme or inappropriate.
