When you buy a home or refinance, a mortgage broker can be a huge help. Brokers don’t lend their own money. They shop your situation to several lenders and try to find a loan that fits. A good broker saves you time, explains confusing parts, and can sometimes get a better rate or lower fees than you would find on your own. But a broker only helps if they are working for you, not just chasing a commission. Here is how to tell the difference before you sign anything.
Start with money. Ask the broker exactly how they get paid. Some are paid by you through a broker fee. Some are paid by the lender through a credit or a higher rate. Some are paid both ways. If the broker says, “Don’t worry about it,” that is not an answer. Ask for the amount in dollars. Ask whether that money is already baked into the rate or closing costs. A broker who is upfront about pay is usually upfront about everything else. A broker who dodges this question is showing you their business style early.
Then ask which lenders they actually compared. A real broker should be able to name several lenders and explain why each one fit or did not fit. If they only mention one lender, you are not getting broker service. You are getting a salesperson for that lender. Ask if they checked banks, credit unions, online lenders, and lenders that work with people who have less-than-perfect credit. If your credit is strong, ask if they checked the big names you could call yourself. You want proof they shopped, not just a promise.
Ask for side-by-side options. Not just the monthly payment. The monthly payment can hide a lot. Ask for the loan amount, the interest rate, the length of the loan, the points, the broker fee, and the total closing costs. Ask for a written Loan Estimate for the top two choices. That form is designed to make lenders show their numbers in the same order, so you can compare apples to apples. If a broker will not give you a written estimate, stop there. Verbal quotes are not worth much when you are signing real papers.
Watch out for “no fee” or “no closing cost” promises. Nothing is free. The cost is still there somewhere, usually in a higher rate, a bigger loan balance, or a lender credit that gets paid back over time. That does not mean those loans are always bad. Sometimes paying a slightly higher rate to keep cash in your pocket makes sense. But you should know what you are trading. Ask the broker to show you the same loan with and without the credit. Then decide which math works better for your plan.
Ask about the rate lock. A rate lock protects you if rates go up before closing. It can also cost you if rates fall and you are stuck. Ask how long the lock lasts, what happens if closing is delayed, and whether there is a float-down option. Get the answer in writing. Also ask who pays for any extension if the seller or appraiser slows things down. These details matter more than a flashy first quote.
Check the broker’s license. Every mortgage broker should have a license number, often called an NMLS number. You can look it up online with your state regulator. You can also check complaints with your state attorney general or consumer protection office. This takes ten minutes. It is worth it. You are letting this person handle one of the biggest financial decisions of your life. A clean license and a short complaint history are not a guarantee, but they are a good start.
Finally, compare the broker’s offer with at least one direct lender or credit union. Do it within a short window, ideally the same week, so your credit score treats the mortgage shopping as one event. A broker should welcome the comparison. If they get angry or push you to hurry, that is your answer. A good broker knows they are not the only option and acts like it. They return calls, explain the tradeoffs, and never make you feel dumb for asking questions. If they cannot do that, walk away. There is always another broker, another lender, and another loan. Your job is not to be loyal. Your job is to get a mortgage you can live with for years.
