What is a mortgage banker? Duties, fees, and loan options

A mortgage banker is a person or company that originates and approves home loans. Smaller operations may fund those loans directly or arrange the funding, then sell and service them later. Many mortgage bankers work for banks and lenders like Rocket Mortgage, though, where the institution handles funding and what happens after closing.

Understanding who and what is involved in the mortgage process can better prepare you to buy or refinance a home.¹ Here’s what a mortgage banker does, how they get paid, and how to pick the right one for you.

Key takeaways:

• A mortgage banker often originates and approves home loans for a specific lending institution, while brokers work across several lenders. At most lenders, the institution handles funding.
• Bankers, brokers, and loan officers all have the same general job to get you from application through the process to the closing table. The difference is that brokers will shop your application to one of several institutions they work with.
• Compare rates, origination fees, closing costs, and terms before you choose. Getting preapproved first helps you shop with confidence while also comparing Loan Estimates to see who can give you the best deal.

What is a mortgage banker?

A mortgage banker is a person who originates home loans. They take your application, help you pick a loan, and guide you toward approval and closing.

Mortgage bankers often work for one lender and offer that lender’s loan products. A broker is a type of mortgage banker who shops an application to several lenders. Either way, funding is typically provided by the lending institution behind the loan.

What does a mortgage banker do?

A mortgage banker works with you from application to closing, and then the loan moves on to whoever funds, owns, or services it. Here’s how it typically goes:

1. Application and documents. You share your income, assets, and debts, and your banker gathers the paperwork.
2. Underwriting. A review of your finances verifies that you meet the lender’s requirements and the loan program’s rules.
3. Final approval. Once everything checks out, your loan is approved.
4. Funding and closing. The lender provides the money, you sign your closing documents, and the loan closes.
5. After closing. The loan is either kept or sold, and someone begins servicing it.

As we’ll see, this doesn’t always happen with one person. Lending involves a diverse skill set.

"I try to build a connection with everyone I talk to. I want to understand what they want to do and how it fits in with their broader goals,” says Leena Boji, Triple Crown Banker at Rocket Mortgage. “If there isn’t a fit right now, we work on setting them up for the future. If the timing is right, we find the loan for them. Along the way, they work with me and a team of experts in their craft, whether that’s an underwriter or closing specialist. You’ve got a team behind you."

Originate loans

With some lenders, a mortgage banker handles everything from taking your application to underwriting the loan. At Rocket Mortgage, we split underwriting and closing into separate functions, and specialists in each area handle them.

That means different teams focus on different stages of your loan. Your banker helps you find the right loan product. Because they can only issue loans from their lender, you’ll need to meet that lender’s requirements. Brokers work with several lenders. When everything’s in place, you’re ready for closing on your home.

Provide funds

Funding for your loan comes from the company the banker works for or a warehouse line of credit, which is a short-term credit line lenders use to fund loans until they sell them. In some smaller operations, the banker directly funds or arranges the loan. More commonly, the institution they work for or with handles it.

Sell or service loans

Some mortgage bankers are also responsible for selling loans after they’ve been originated. Lenders often sell loans on the secondary mortgage market because it gives them cash to lend again without waiting for borrowers to pay their mortgages off. At larger lenders, bond traders, not the banker you worked with, handle those sales.

A servicer collects your monthly payment and helps with any issues that come up over the life of your loan. A lender can sell your loan and keep the servicing. If the loan or its servicing moves to a new company, you may send your payments somewhere new, but your loan terms stay the same.

Rocket Mortgage retains servicing on most of the loans it sells. In fact, we service one in six mortgages in the United States.² Here’s more on what it's like to have your loan servicing through Rocket Mortgage.

Mortgage banker vs. mortgage broker

The big difference is the employment relationship. A mortgage banker works for a lender and offers that lender’s loans. A mortgage broker works with different lenders. Let's compare:

• Mortgage banker. They work for a lending institution, help you pick from that lender's products, and close the loan in the lender’s name with its funds.
• Mortgage broker. Working as a free agent, a mortgage broker gathers your information and qualifies you by comparing options from multiple lenders. The lender funds the loan, not the broker.

A banker may suit you if you want one team to take you from application to closing. Finding a broker may suit you if you’d like someone else to gather options from several lenders. Some financial institutions operate as both, so it’s worth asking who’s involved in your loan.

Mortgage banker vs. loan officer

Is a mortgage banker the same as a loan officer? In everyday conversation, often yes. Many people use both terms for the person who works with you on your application, and a loan officer is also called a mortgage loan originator.

How do mortgage bankers make money?

Mortgage bankers and brokers are usually paid a commission, which comes from you or from the lender. Lenders can also pay a salary, a fixed amount per loan, or a percentage of the loan amount.

But they won't put you in the loan just to make more money. Federal law prohibits a loan originator’s pay from varying based on the terms of your mortgage. That means they can’t earn more by steering you toward a more expensive loan.

Origination fees

An origination fee is what the lender charges for making your loan. It can cover taking your application, underwriting, funding, and other administrative work. You’ll see origination fees on your Loan Estimate, and they’re part of your overall closing costs.

They generally can’t increase at closing. If the fees that can change go beyond a narrow difference, a new Loan Estimate has to be issued.

Selling loans or servicing rights

Most lenders don’t make money off the interest payments from your mortgage in the long term. Waiting 30 years for loans to pay off would severely limit how many loans could be made. Most loans are sold on the secondary market after closing because of this.

Servicing rights enable lenders to maintain a relationship with you throughout the life of the loan and also get paid a small amount by the new bond investor for forwarding the payments and handling the loan administration.

What loans do mortgage bankers offer?

The loans a mortgage banker offers vary by institution. A mortgage banker affiliated with a lender can only offer the products their employer provides. If your banker is acting as a mortgage broker, they can offer products from the different lenders they work with. Take a look at the types of loans available from Rocket Mortgage.

Common loan purposes

Mortgage bankers commonly help with these loan purposes:

• Home purchase. A loan to buy a home.
• Rate-and-term refinance. A new loan that pays off and replaces your existing mortgage to shorten your term, lower your interest rate, or decrease your monthly payment.
• Cash-out refinance. A refinance for more than you owe, so you can take the difference in cash. A cash-out refinance usually means a bigger loan and a new term.
• Home equity loan. A home equity loan enables you to access your existing equity as a second mortgage if you don’t want to touch your current rate.³A mortgage banker can help you with a blended rate calculation to help you determine whether this or a cash-out refinance makes sense.

Do you need a mortgage banker?

Lenders won’t let you approve your own loan with their money, so you do need a mortgage banker. But you can shop around in order to get the best deal by getting preapproved with multiple lenders and comparing estimates. More on that in a minute.

How to choose a mortgage banker or lender

Choosing a lender is just as important as choosing a home, since the terms you get shape what your home costs each month. These steps will help you get a mortgage that fits.

Make sure you’re ready

Lenders use your credit score to judge how likely you are to repay a loan. In general, higher scores get lower interest rates, and your score can affect which loans you’re eligible for and the deal you can get from the lender.

Most loans also require some sort of down payment or equity. In general, the less a lender has to loan relative to the value of your home, the better your rate is going to be.

Beyond that, paying down existing debt will lower the amount of required payments each month. This could give you the ability to afford a bigger house payment to get the extra bedroom you’ve been looking for on the market or finally remodel your kitchen.

If your score isn’t where you’d like it, that can change. Taking steps to repair your credit before you apply could open up more loan options and better terms.

Shop around for loans

Shopping for a mortgage by comparing interest rates, origination fees, closing costs, loan terms, servicing practices, and available loan products ensures you’re getting the best deal.

Keep in mind that a low interest rate can come with higher fees in the form of points, so compare the full cost of each offer. The annual percentage rate (APR) includes the full finance charges.

Your comfort with the lender also matters. Here are questions to ask a lender.

Apply for preapproval

A mortgage preapproval is a letter from a lender saying it’s generally willing to lend you up to a certain amount. It helps you know the top end of what you can afford and shows sellers you’re serious.

A traditional preapproval involves a credit check, income, and asset documentation. If your lender doesn’t do that, it’s just a prequalification. That can be a good estimate, but without verification, it doesn’t carry weight. Even with a preapproval, you’ll need to go through underwriting and often need an appraisal.

FAQ

Let’s answer some other questions you might still have.

Do you need a degree to be a mortgage banker?

Federal law focuses on education hours, testing, and background checks rather than a college degree.

State-licensed mortgage loan originators register through the NMLS. They provide fingerprints for a criminal background check, authorize a credit report, and pass a national test. They also complete 20 hours of prelicensure education: 3 hours of federal law, 3 hours of ethics, 2 hours on nontraditional mortgage lending, and 12 hours of electives. There is also required continuing education every year.

Each state can add its own licensing requirements, such as more education hours or state-specific coursework, so the details depend on where the banker works.

Do mortgage bankers retain servicing of the loan?

Some do, and others sell the loan or its servicing rights after closing. For most mortgage bankers, that’s a decision for the lender or lenders they work for or with, not something they focus on day to day. We maintain servicing on most of our loans.

Do mortgage bankers charge a fee?

Lenders typically charge an origination fee for making the loan, and it can cover processing, underwriting, and funding. Scrutinizing Loan Estimates can help you compare offers.

How long does mortgage approval take with a mortgage banker?

It varies. The timeline depends on your lender, the loan type, and how quickly you provide your documents. If you're buying a home, your application technically isn't complete until you have a signed purchase agreement on a home.

Your lender must send a Loan Estimate within 3 business days of your application, and you must receive your Closing Disclosure at least 3 business days before closing.

You can walk through the mortgage loan process to see what happens between those points. From the time of your completed application to just before you close, we average just under 23 days at Rocket Mortgage as of this writing.⁴

The bottom line: Mortgage bankers help fund homes

A mortgage banker originates home loans for a lender, whether that be themselves, an employer, or one of the lenders they work with. After closing, the loan may be sold or serviced. Lenders offer different options, so it doesn't hurt to shop.

Compare loans, rates, fees, terms, and preapproval options before you pick, so you land on the right fit. If you’re ready to get started, you can apply online today.
