Walk into your bank for a mortgage and you get exactly one offer: theirs. That’s not a knock on your bank — it’s just the structure. A retail loan officer can only price the products their own institution underwrites, at whatever margin that institution has built in. There’s no second option in the room, and no competition working in your favor.
A mortgage broker works differently. Instead of representing one lender, an independent broker shops your loan across a wide network of wholesale lenders at once, all competing for the business. That competition is where the savings usually come from — not a discount, but an actual market being allowed to work the way markets are supposed to.
What the data actually shows
A 2023 industry study analyzing HMDA lending data found that consumers save an average of $10,662 over the life of the loan when working with an independent broker instead of a retail lender. The gap was even larger for veterans using VA loans — an average savings of $13,432 per loan, with brokered VA loans also landing a lower average interest rate than retail (6.26% vs. 6.40%).
Note: this figure comes from a study commissioned by a wholesale lender, so it’s worth reading as directionally accurate rather than gospel. Real outcomes vary by borrower, lender, and market.
Why the gap exists
Banks price to cover their own overhead and hold to their own internal credit guidelines — often stricter than what Fannie Mae, Freddie Mac, or FHA/VA actually require. Brokers access wholesale pricing across multiple lenders simultaneously, so if one lender’s fees or guidelines don’t fit your file, another one usually does. You’re not asking a single lender to be fair to you. You’re letting several compete for your business at the same time.
When a bank might still win
This isn’t absolute. Borrowers with excellent credit and a deep relationship at their bank — significant deposits, existing accounts, private banking status — sometimes get real relationship pricing that’s worth comparing. The point isn’t that banks are never competitive. It’s that you should never assume your bank’s number is the only number, or the best one, before checking it against the wider market.
The bottom line
A broker isn’t selling you a product. A broker is shopping the market on your behalf and showing you the results. That’s worth something on every loan — and worth quite a bit more on the loans that don’t fit a standard box.
