Ok, a couple things. Buying a house is something to consider as long as housing costs in your area are not toooo bad.
Also, consider asking parents for help as many med students do, ask your tax advisor about this. There are lots of areas to reduce the out of pocket on a home using tax breaks.
Finally, in response to the above.
1) Buy house and pay house payment while in school with student loan money.
Maybe an ok Idea...if you allready have a big nestegg or outside support. Most student loans will give you about 500 bucks a month for housing. That is about enough for a 75-90k (if you can find a house for this, then go ahead, I have no idea where it would be though) loan depending on your rate. If you could rent to a roommate, that would help a bunch as long as you can come up with the 20% down payment and manage the property with ALL your free time.
2) Move to new city for residency, rent house out to cover house payment and live in inexpensive apartment. Pay off house as quickly as possible.
Because managing a property while you work rediculous hours far away for little money is an easy thing??
3) Sell house and invest all proceeds in ~10-15% mutual fund. Do not touch. Pay off student loan as slowly as possible and beat the student loan interest rate on the market.
Considering all things, since I am buying a house and a finance and acounting professional going to med school, I think I have some credential to say probably not going to pan out this way.
Assuming you have poured all your equity into the house since you started working. Maybe you end up taking away 80-90k in gain. If the market stands or goes up. This is a pretty risky time to bet on that. I would plan on not going up at this point.
Finally, 10-15% mutual funds grow on trees. Haha, good luck with that. assuming you pull out 75k in gain when done with residency at 30, assume you beat your loan rate by 5% (this is probably a huge overestimate with a small amount of money like 75k). It would take you 20 years to catch up to pay a loan that was 150, from your original 75. Remember the loan grows as does your investment. Assuming you didn't put more of your own money in.
4) Become debt free in 40s with sizable portfolio.
If you get 100,000 for your house and find a conservative 12% mutual fund to invest in and don't even add to it, that grows to just under $3,000,000 in 30 years.
So far being a homeowner has been great, though it's tough to afford anything nice on the amount of loan money you're allocated. I've had a few tight months and have had to cut out some extras but I think things will work out in the end. It helps to buy a cheap used car with cash because those car payments will really hold you back.
Being frugal and conservative is the first step to wealth. Props on the hard work and gumption to get it going. I just want to shed a little opposing light so we don't have a bunch of eager people jumping on houses unprepared.
If you do...cheap house, very frugal life, a decent chunk of work outside of school, and no guarantees.
