The towns of the Sierra Madre are some of Jalisco’s oldest communities. Mascota was bigger than Guadalajara at one time. San Sebastian was once a bustling silver mining town with more than 20,000 people; today, it has less than 500. Among these towns, Talpa has seen the most real estate purchased by foreigners who want a second home in the mountains, where the weather is temperate year-round. All three towns are a couple of hours from Vallarta, popular to visit, but not in great demand by expats looking for a second home, so far.
