The work force in the mortgage business waxes and wanes with the interest rates. When rates go up, volume slows and people are laid off. When rates go down, it is hard to staff up quickly enough to handle the added volume of loans that come with it. So people are hired from almost any field.
There was a joke in the industry, "Yesterday a go-go dancer, today an escrow officer," because it was hard to find people to work in an industry where layoffs were sometimes frequent and unpredictable.
"Yesterday a bartender, today a US congresswoman."
The joke writes itself. :-)
Lol. Did you see the movie The Big Short?
”I was a bartender. Now I own a boat!”
