And many think it is worth it. I have friends in a family from Laredo, Texas, that I have known since I was a teenager. They have lived there for 5 generations, and even a school and a park and a city building are named after them. Half of them have also moved to San Antonio.The cost of living is also 35% higher in San Antonio.
Yes, San Antonio is more expensive. It is also a lovely city. We joke about calling McAllen "McAwful" as it has the same crazy zoning as Houston and is less than attractive in that sense. But it used to have the nicest people of any of the US mainland markets I'd visit; now they are all scared.
Real estate values from the Gulf to Del Rio have declined in the last two years, while in San Antonio and Austin they have increased 50% to 100% depending on the area.
I'm about 100 miles from the border and have new neighbors from Brawley and Calexico and El Centro who have farms in Imperial County. They had such fear for their families that they now commute three or four times a week to their business, and do the rest online from the Coachella Valley. Yet even our area has a huge increase in shoplifting, car theft, burglaries and the like.
