It sounds like some incoming physicians doing their residency here have been receiving bad information about available mortgage options

The mortgage market has changed dramatically over the last two years. There are now only about a half dozen zero downpayment mortgage options now where two years ago there were about twice that many. (And they were dramatically more available.)

But, when you are buying a home you only need one mortgage, and if you are a physican here for your residency then realatively easy zero downpayment options are still available.

It will take some preparation and there are some limitations, but in general the Midwest Financial Credit Union is still a good option.

They offer:
Closing before  first paycheck
Zero downpayment
Ignoring student loan obligations in most situations
No PMI (but a higher interest rate to compensate for some additonal risk.)
A  physician friendly application process

Note: These loans are specifically for physicians, so they are not visible on the credit union's website.
