Sounds like a great idea, well, except for the Texas part.
If it's a cultural issue, Austin sidesteps that problem nicely.
I live in Texas and might be moving to SF area. My 2000 SF house here is cheaper than a 1 BR apartment there and no income tax. Prop taxes are a little higher (4% per year). Financially it's way better here but job wise not as much.
Unless you can make 200k all included, don't do it. It'll be a step backwards.
(Unless you make 50k in Texas, in which case, do move, you can always move back, and cling on to the new salary bar)
It boils down to jobs. Texas is a fine place to live if you work in certain sectors. California is great place to live for other kinds of work.
It's a very pleasant 96*F today!
80˚F in San Antonio right now.
Air conditioning's been around for 100+ years. Start using it.
