Anyone here live in the Eastern outskirts of Austin?

Maybe some context of my situation now would help. This is my house at the top of the hill here

This is my backyard

And the pole barn where I get to spend some quality time working on the old car. Concrete floor, insulated, wired, lights, and it has a heated/air conditioned workshop inside.

I've got 12 acres here now. This is my backfield where I get to cut up the trees that come down for firewood. I didn't even have a chainsaw before I bought this place almost 10 years ago, but I found there's something strangely enjoyable about cutting up firewood.

And for comparison, my property taxes here are $2900 a year. And I have less than 2 years left on the mortgage.

I could realistically expect to get about mid 3's for this place, which won't buy me anything even close down there. The more I think about this, the more it doesn't make too much sense. The job sounds like a dream job, but I don't know if the rest of the deal is worth it.
