The towns of the Sierra Madre are some of Jalisco's oldest communities. Mascota at one time was bigger than Guadalajara. San Sebastian was once a bustling silver mining town with more than 20,000 people, today there are less than 500. If any of the towns have seen real estate purchased by foreigners who want a second home up in the mountains where the weather is temperate year-round, it is Talpa. The three towns are a couple of hours out of Vallarta and are a popular place to visit for people in PV. But so far, it has not been of great demand for expats looking for a second home.
