More than in the Bay is hard to believe for Texas considering software engineers can get >400k these days if you know where to look. I'm assuming it's an oil company?
I will never draw a Bay Area salary. But I have a great house and a kid in a good private school for <50% of the cost to live in SFO.
That is far above average.
I don't know about the 400k specifically, but I hope you might want to change your attitude: you don't need to sell for what you believe is reasonable and can imagine; you want to be selling to people who have more money than sense.
