saw the link about the whitecoatinvestor, I can't say I agree with him... Yes, he says how he can save money for retirement... but he isn't doing it for ER//FI. I don't know if it is the same whitecoatinvestor since it's a different site and just same name but
http://forums.studentdoctor.net/threads/an-emergency-docs-budget.817037/. Even with all of his savings, while I have no problems how he spends his money, I don't think he should give advice while he himself is still "living in debt" as evident that he could have paid off the debt but chooses to spend money on something that isn't the debt so IMO he's living on debt the same as the walmart guy living on credit cards... If he had paid off the debt and not rely on having it forgiven than that would be "his" money to spend, but as long as he is "in debt" I feel like he shouldn't be able to live so spendy on tax payer money/private loan money but that isn't up to me.
The only reason I bring this up is that my sister just graduated med school and starts residency in a few weeks. She'll have $250k or so in debt and yes she will make close to estimated $200k/year after 3 years of residency, her plan is still to work 10 years and have it forgiven. I'll didn't go to med school and I make $50k/year and will continue to make that (adjusted for inflation of course in future). But I also don't work 80 hours/week like she does in residency, if I choose to work that hard I would be making $100k/year. But even without working extra hours, I'm on track to FIRE with $1m by the time I'm 40, 12 years. She is 26 now, will be in residency until 29-30. If she doesn't do a fellowship, she could start earning the $200k/year and have the debt paid off and be a millionaire by 40 as well. However, her plan is to work 10 years to let the loan be forgiven while slowly saving for retirement (IE: 10-20%/year) and "live like a doctor" in the meantime, meaning she still has to work until 60. Becoming a doctor is a "life" choice, while my job is one where I have no problem giving up. It's my way to becoming FI, and I'm not as invested in living my life as my career title. Being a doctor really is something that sticks with you for the rest of your life but that makes it harder to FI. Sure doctors save lives, but once I FI, I could also do as much good. Plus since I work as a medical technologist in hospitals, I kind of "save lives" as well, indirectly but still...
The only advice I can give and this might not be the best case for you is that it wouldn't be a bad idea to take out more federal loans to pay off the undergrad loans that are private. The loan forgiveness only works on federal loans if you weren't told that. As well as federal loans have a slightly lower interest rate. So if you take out $120k loan to pay off $100k debt, or you take out $20k loan for med school and leave $100k loan untouched, you'll still have same debt amount. This is just to consolidate all your loans into one place and with the goal of having it forgiven.
And then there's the entire loan forgiveness thing, do you really want to risk it not being forgiven or having it capped? I've read news articles about talks to cap the loan forgiveness. Regardless, 10 years is a long time for programs to change, so it may not even be around by the time it's your turn to have it forgiven.
Best advice I can give is not rely on it and live "like you are still in residency" once you are out for the first 5 or so years and just pay off the debt instead of waiting around for it to be forgiven. But since my sister isn't listening, it may be a moot point, all my doctor friends and her's are already 2 weeks out of med school starting to inflate their lifestyle. She will be given a work phone to use but she's already went and bought the galaxy s5 last week and doubled her cell phone bill (even if $50/month isn't "bad", it just isn't reasonable to me either). She's already talking about her next new car although she's smart enough to know she can't afford it YET. But I have no doubt that once she's "saved" enough, she'll think she can afford it and there goes her retirement money.
edit: fun fact, her graduating class of about 300 doctors as of today (so no interest yet) has a total debt of about $52 million. Imagine what happens when it is forgiven and think about why the politicians don't like the loan forgiveness talks. A reason why they talk about capping it.
