Yup. Too few people understand that almost all of these companies are solely loan origination and loan servicing.
They are not providing the capital, they are not making money through interest. They have almost no control over the rates they offer you.
They make money when a borrower signs a new loan agreement (origination) and by collecting the payments the borrower owes and passing them along to the real lender (servicing).
If you're wondering why your mortgage company used to keep calling you telling you to refinance (and some still are, even with the higher rates), it's because that's another loan origination for them - another payment. They don't care that you save long term on the interest, they want the payment for closing a new loan.
Same for loan consolidation (ex: consolidate your auto/credit debts!) style pitches. They're ONLY interested in originating a new loan, because that's how they get paid.

Basically - these guys don't have anything other than you, the borrower.
They're not selling you a loan, they're selling you to real lender, which is almost always the large government backed mortgage lenders (Freddie/Fannie).
This is why they jump to call you, or text you, or harass you. They are out there fishing for new borrowers to make money.
