This has been discussed quite a bit in the past and I would encourage you to do a search for these so we don't continue repeating everything.
To try and keep it short -
I too wanted a "contract" from a group who would help pay my school costs and a stipend while attending school. I found it and was offered "the deal". It was a LOUSY DEAL and I turned it down without hesitation. I did what many people do - realize that the "burger today - for X # of years of service tomorrow at a reduced wage" is usually not the "deal" that you're going to be happy with!
I toughed it out through school with loans and kept the spending down. During the last year I started "shopping the deal" with various groups. Actually, my spouse did most of the real "homework" - which is interesting when you think about it, he's simply very good at this type of thing. When opportunites looked good, we'd schedule an interview and make the trip. We inked a deal about 6 months before graduation and it has been a roller-coaster ride ever since!
I am SO PLEASED with where I landed and the practice I am in today! Also, The money is about 2 1/3 times more than what I was offered by the group initially. The loans? I owe plenty, but it's not a problem. Consolidate them for about 2-3% over anywhere from 10-30 years! Let's see here... can I afford this? The interest is deductible (if you do your homework right - or have a good CPA) and voila! Life is "sweeeeeeet!"
PS - PLEASE don't e-mail me asking for the stipend group - or my school for that matter - I wouldn't wish either of them on anyone!
