Your federal student loans can be consolidated for 30 years at around 4% now. Figure the $300K home loan at 30 years at 7% and the $500K practice loan for 7 years at 8% and your monthly payment on these three thing will be about $11K per month.
Those interest rates are assuming you have good credit (which you won't if you owe all this money), you have all federal loans (which I don't think you can if you owe 200K) and you can put 20% down on the house (do you have 60K lying around?).
There are people who will loan you money like this but you will not get such good rates as those above. The "dental lenders" like Sky, Matsco, HPSC have some terms that MIGHT be seen as preditory. I know several guys who used them and paid for 5 years of a seven year loan and wanted to pay it off now that they were financially able too. Their loan was structured such that all the interest was paid off first and they still owed basically all the money they originally borrowed. That's fair and high risk borrowers can't be choosers, but IMHO you would be better off starting in a smaller house, saving some money in the beginning, and then once you're better off financially, live like a doctor.
If you have a spouse that works it would be very easy to live moderately (not frugal or extravagant) and save $150K+ in two years. That would put you in much better shape as far as getting reasonable loan rates which would save you lots of money for a long time.
