Another nurse here... I think the major advantage of getting your BSN will be future flexibility. Like you said, not a huge pay increase, but a lot of hospitals are starting to require it for new hires (it helps with magnet status, etc). So if you are very sure you will be happy in your current position until FIRE and don't plan on working PT or travel nursing later, then forget it. If your current job starts pushing you, try to get them to pay for it, it'll help the total cost if you wanna do the CNP thing later. If you may want to work part time or travel in the future, then I'd get it to make yourself more attractive to the market place. SemiRE is a great option for nurses & doesn't take that long to get there, you could be travel nursing for only 3 mos out of the year and make 30-40K to live on while you let your stash grow you to FI, not a bad deal at all.
