winged scapula said it best, you can't have your cake and eat it too..
if you specialize, your loans are NOT an issue, period point blank. even at at unrealistic 7%.
if you are in primary care, lets say pedes, fp, or im:
lets say you bring 150k in the door, at the end of the day, meaning this is your net profit (you or your corp) AFTER taking every possible deduction..
lets say your total federal/state/local liability totals some 33%... in the interest of round numbers.
you are left with 100k in disposable income.
i am assuming you have allready contributed to your sep or ira (non roth in this case) or whatever pre-tax pension you have set up..
so you have 100k to play with..
lets break it down:
if you are living in an average 4 bed 3.5 bath in suburbia USA, depending on lots of factors lets say that home will cost you 400k on average. in some places less, in some more. lets play the middle.
depending on where the rate is in the next few years, lets say you end up at 7% on your 30 year money. 7% on 400k plus taxes/insurance will chew up
36k.
you now have a home, and 64k to spend.
lets not forget: your home will have maintenance! lets set aside 4k, which really barely covers it.
60k left, but you have a roof over your head.
now we need a way to get around. lets face it, you will always have a car payment because you will always want a car less than 5-6 years old.. most of us that is:
a new f150 will run around 35k fully equipped, likewise a lower end 3 series BMW.. so with insurance the 2 cars will run us about: 20k per year.
now we are down to 40k...
oops what about gas and maintenance on those? about $600 total per month:
down to 33k..
and we havent eaten, or clothed ourselves, or had a baby, or 2 or 3, bought a tv, couch, bed, etc etc, household goods, vacations, etc etc..
oops what about those student loan payments, that nagging credit card debt??? child support/alimony?? hobbies?
pretty grim..
not trying to scare anyone, but its HARD to make 150k work unless A)you have no kids, or B)you have a spouse bringing $$ in the door. C)you are very lucky in your investing.
