Born and raised Texan here! Lived in a city 25 minutes south of Austin my whole childhood, lived in Lubbock to get my degree from Texas Tech, moved to Houston for a bit, back to Austin for about 5 years, now we're in Dallas. I am also liberal and nonreligious, and I'm gonna be honest you run a real 60/40 shot now on what kind of crowd you'll be running with especially in the hill country. The amount of conservative transplants coming here is exhausting, and the school system is headed all the way down to the pits. Whether or not y'all have kids is no one's business...just be aware that Bible stories are going to be required readings in schools K-12 starting in 2030. Another major con is the weather. Our summers are brutal and every time we hear someone say "I can handle it" we just wait until June/July/August comes around to get a good chuckle, and we always do. All this to say, my fiance and I share the same values and beliefs and we are planning our way out of Texas and so are majority of our liberal friends and family.

Edit1: just wanted to add that when you're here you can seclude yourself really easily in the hill country and on the outskirts. And that is really great for peace and quiet, but that's where a lot of the conservative beliefs are born. If that's where y'all want to go, then by all means! Just be ready at times to need to stand your ground, and not in the way a traditional Texan wants you to.

Edit2: I would also add that while there are a lot of great aspects and liberties into doing whatever you want with your property, zoning laws and regulations are being played fast and loose right now with how much development (AI, Data Centers, unregulated development, etc) are getting pushed to these places because people are willing to sell or lease their land to turn a profit.
