AnEDO, that is a good point and definitely worth considering. It's unclear what the actual job description is. I will build on knowledge and skills I already have as well as learning new, so it could affect that.
If the job description is clear that I could do some of this remotely (ie correspondence via email, etc), I can just do this over my hour lunch break at work (which much as I would like to fool myself, I probably wouldn't be doing school work anyways). In my personal life, I'm child-free and unmarried. My partner is super supportive and has basically said he wants me to do whatever it takes to fulfill this dream, even if it means seeing him less/devoting less time to the relationship.
In terms of the program itself, it'll help boost my salary (with a new job) by probably 10-20k/year at first and it could double at some point, which would be GREAT to save half/more of my salary.
These have all been really great questions and are really helpful in thinking about the pros and cons. I really appreciate it and if anyone else has thoughts, I'd love to hear it.
