Those scores are pretty good, but that is a serious derogatory credit item.
Physician loans are portfolio programs, so the lender is free to implement their own underwriting guidelines, but this also means they can probably make a judgment call on things.
If the rest of your credit otherwise is good and you can provide a good explanation then hopefully this will be OK.
If not then you may have to go FHA. It's 3.5% down and you'll probably have to wait until he starts working. But it's an option nonetheless.
If it doesnt work then try another lender who offers a physicians loan before you give up and go FHA.
Best of luck!
