Both can get you to a closing table. They differ in who holds the money, whose guidelines apply, and what happens when your file does not fit the first box.
A bank or credit union lends its own money and offers only its own products and guidelines, with in-house underwriting. A mortgage broker is separately licensed, does not lend its own money, and instead takes the application and submits it to a wholesale lender that underwrites and funds the loan. The practical difference is program breadth and flexibility: if a property or income situation does not fit one set of guidelines, a broker can look at other program options, while a bank can only offer what it holds.
At a bank, one institution takes your application, underwrites it, funds it and often services it. The loan officer works for the lender, and the guidelines are the bank's own — sometimes agency guidelines, sometimes stricter overlays the bank adds on top.
With a broker, the roles split. The broker is licensed by the state and registered through the NMLS, takes the application, gathers and verifies documentation, structures the file, and chooses the program. The wholesale lender underwrites, issues conditions, draws the closing documents and funds. The broker does not approve your loan and cannot overrule an underwriter — a distinction worth understanding before anyone promises you an approval.
Banks do well when your file is clean and conventional, when you have a deep existing relationship that comes with pricing benefits, and when you value having one institution handle everything including servicing. Some banks also have portfolio products they keep on their own books — construction lending, unusual property types, relationship jumbo — that no wholesale channel offers.
Brokers do well when the file has something in it that needs thought: self-employment income, recent credit events, a two- to four-unit property, an investment purchase, a jumbo loan amount, a rural property that might qualify for USDA, or a borrower who does not know which program fits. Program breadth is the point. So is having someone whose only job on the file is your file.
Get a Loan Estimate from each. It is a standardized federal form, which means the costs sit in the same boxes and are genuinely comparable — unlike informal quotes. Collect them within the same day or two, because pricing moves with the bond market.
Then compare the same rate on both, the total closing costs, whether points or credits are included, and the lock period. And ask both the same questions: who underwrites this, what could change the price after today, and what conditions do you expect on my file.
A bank lends its own money and offers only its own products and guidelines, underwritten in house. A broker is separately licensed, takes the application, and places the loan with a wholesale lender that underwrites and funds it. Brokers typically offer a wider program menu; banks may offer portfolio products no broker can access.
Brokers are able to work with more than one wholesale lender, and many do. Ai Remco LLC currently originates through one primary wholesale lending relationship and compares the programs available within that channel — conventional, FHA, VA, USDA, jumbo and Non-QM.
Not inherently. Broker compensation is disclosed and reflected in your pricing and Loan Estimate, and federal rules prohibit compensation that varies with loan terms. The only reliable comparison is Loan Estimates from both, obtained on the same day.
The lender's underwriters, applying that lender's guidelines. A broker structures and submits the file and can advocate for it, but cannot issue an approval.
