A lender colleague of mine told me that over the past two weeks there has been more initial loan & refinance applications than he has seen in the past 6 months alone due to the low rates. 

Gave out a total of 50 applications. 

@Bjorn AhlbladAccording to his rental application he does meet criteria however he is yet to show proof.

The 0% is not on loans - this is the federal interest rate - lenders base their interest on the number of application for refi and for new loans.  

I HATE doing the same application info to each individual bank over and over....good mortgage broker?

It is time consuming, because of all the paperwork that is needed for the application process.I suspect all this will be over once the warm weather hits and spring is sprung into action, at least in my neck of the woods.

Treated as an S-Corp if applicable.

Mortgage rates are based on number of applications and demand.

Lenders are pricing themselves out of the market until their underwriters catch up, then lowering rates a ton until back at capacity, then jacking rates right back up once they've gulped in a bunch of refi applications. 

I began a refinance in October 2019 and have an email message from Omar Santoyo, a NMLS, on October 14 2019 that my application was complete.
