Which position would you choose: RN supervisor or utilization management?

This is very long, like novel length--I'm sorry. So I have a dilemma. I applied for two internal positions at the company I work for, which specializes in mental health and substance abuse. One is a nurse manager position of our inpatient unit, and the other is utilization management.

I only applied for the nurse manager position because the nurse administrator really wants me in that position. I was hesitant about it at first, because soon it's going to be an involuntary unit which makes for an extremely stressful atmosphere. One of the supervisors (non-clinical) on another unit got choked out today, and that's a voluntary unit! So yeah, involuntary is even rougher. But, thinking about the money definitely made me excited. It's $86,000 per year. The schedule is flexible, usually M-F 8-4 but they usually leave early. The positives are: flexible-ish schedule, money and experience. It would be my first supervisor position, so that would look good on my resume. The cons are: on call once a month and you only get an extra $100 for the entire week, high stress, high turnover, lots of call outs, and if one if the floors is short and three rounds of bonuses don't turn up a nurse who's willing to work, one of the three supervisors have to work it--and I don't think we get the bonus.

Now, the utilization management position is something I willingly applied for before I knew about the nurse manager position. I know a nurse who does it and she LOVES it. She actually used to be a supervisor and said she'd choose UM over that any day (so maybe there's my answer?) but maybe she doesn't need as much money as I do. I have five kids and I think she has like one who's grown already, so yeah, big difference in terms of financial responsibilities. Pros: I will be able to work from HOME after a few months of training!!!! This is huge for me. I worked from home for 7 years and miss it a lot. Also, I will get experience in UM (which I've wanted for years now) and there are tons of insurance companies that hire nurses work from home, so if I ever need to move on from this company there are many options. The schedule is flexible. They said if I need to take a few hours off one day, I can just work a few extra hours the next day to make up for it. One of the main pros is that I won't get choked out by angry patients because there's no patient care involved at all. Cons: less money. That's the only con. I think it's mid 70's per year but I have no idea.

I'm really leaning towards the UM position, but here's the main dilemma. After the interview, they said it may take a few weeks to hear back because they have other interviews scheduled. I feel like I will get an offer, because the director of nursing seemed impressed and after we left her office, the head of UM told me "that was awesome" in regards to how I did. I was supposed to have a second interview for the manager position yesterday, but that fell through and they have to reschedule (maybe that's a sign to not do it?). I'm 99% sure I'd get that position, and I'm sure that the offer will come quickly after the interview because the current manager's last day is this Friday and they need to replace him quick. So what if I get an offer for the supervisor position while I'm waiting for the UM offer? I don't think they'd let me wait weeks to accept the offer, and what if I never even end up getting the offer for UM? I'm fairly content with my current position, so if I passed up the supervisor position and didn't get the UM position I wouldn't be stuck in a crappy job.

I don't know. Sorry for rambling. I ramble when I'm stressed. What would you guys do if you were me? Which job sounds better? And thank you to those of you who actually read through all of this.
