of us gets accepted into CRNA school FIRST will be supported by the other only to switch roles once they graduate.) However, if I had to work I would try to find a WEEKEND ONLY job. My wife knows a nurse who works only weekends (12 hours each Saturday and Sunday) and gets time and a half in the ICU at a hospital on the North side of Indy. Thus, she earns $45 per hour for 24 hours per week instead of $30.00 for 40 hours (albeit she would only have to work 36 hours to earn 40 at most local hospitals). This may not be possible in all job markets, and in some markets in which it is possible it might require going through an agency.
If you decide to go this route you might wish to apply at CRNA schools
with above average job markets for RN's (if you can combine this with average or below average cost of living then all the better). One city that comes to mind is Houston Texas I think they have at least two CRNA schools and I read that nurses there make among the best salaries in the nation. Also, keep in mind that some CRNA schools will require that you demonstrate your ability to support yourself while in school without working.
In addition, if money is tight consider maxing out student loans while in CRNA school (if you're not already doing this to pay the tuition!) After all what is an extra $30K or so in debt (at below market interest rates) when you will be increasing your salary by MORE than that EACH YEAR after graduation. You might also consider moving to Florida after graduation where they have NO state income tax (as opposed to my ECONOMICALLY insane dream of moving to Hawaii where the state income tax is 9%! If I could only find a job in Fiji or Bora Bora....) The income tax savings could be applied to any accrued student loan debt.
You might also consider trying to find someone who will let you live in their home for minimal rent. Given that you are an RN there are many older people who would truly benefit from this arrangement. This would probably be easier for females than males. Indeed, females might find a part time Nanny/live in position to be beneficial and easy to obtain (just make sure that the people understand that your schooling comes first). In addition, I have read on this site about future employers paying lump sums/ or monthly support in exchange for a future committment of employment (many of these have provisions where by the monies become loans if the CRNA doesn't end up working there in which case you could look at it as a way of borrowing MORE than federal loan limits would otherwise allow. In fact I think FORCING you to work someplace even after giving you money would be considered a violation of the constitutional injunction against involuntary servitude.)
One other option to consider is the MILITARY. They will probably pay for your education outright in exchange for a four to six year commitment after graduation (that's a lot of dough in opportunity cost maybe in excess of a half million but you will be going in as an officer AND serving your country. By the way the involuntary servitude thing doesn't apply here if you play on their dime your going to do the time one way or another!)
Hope something here is of use.
