again I think different banks draft their own guidelines for the loans. The lender I am working with for example has a 90 day grace period from closing of escrow until my first day of work. Similarly they even are willing to give me a prequalification letter on the basis of an unexecuted copy of my contract. I think specific terms vary lender to lender. As far as physician loans are concerned as a whole, they offer a 100% financing option with a competitive interest rate with the the benefit of having no PMI.
