@Wien2NC $17k at NM Tech gets you one semester of OOS tuition, room & board. However, in state tuition for a year is just $7k.
OP, if you really want to pursue this 2nd degree, find a low prices OOS school that has what you want, and move to that state for a year (or whatever it takes) to become a resident. You can find SOME job to pay your way for that year.
New Mexico has some low rates and I think you’ll find CS offered not just at NM Tech.
I am not pro or con getting a 2nd bachelor’s, but just as information, my oldest D and her husband both went back for 2nd bachelor’s (they now each have masters). They basically didn’t really know what they wanted to do the first time around, eventually acquired career goals and got degrees to match.
