Qualifying for mortgage as an S corp self-employed

[stepim]

I'm a self employed sole-proprietor and I want to switch to S corp so I can pay myself a $20K salary out of $100K business earnings. I also want to get a mortgage. For the purpose of the loan application, will I be qualifying as someone who's making $20K or $100K? Is there anything I can do to qualify for a bigger loan without remaining a sole-proprietor or increasing my salary?

If you pay yourself a $20k salary, then that is the number they are going to use to qualify you.

The days of stated income are gone (for now).
