How Each Type of Lender Works
To choose the best source for your mortgage, you need to understand the fundamental business model of each. They're not just different companies. They operate in different ways, with different incentives and constraints.
Mortgage Brokers
A mortgage broker is a licensed intermediary who works with you to find the best mortgage from 100+ lenders. They're independent operators who shop multiple wholesale lenders on your behalf. Here's how it works:
- You apply with the broker
- Broker pulls your credit and pre-qualifies you
- Broker submits your application to multiple lenders simultaneously
- Lenders provide wholesale rates back to the broker
- Broker negotiates terms and presents options
- You choose which lender/terms you prefer
- Broker coordinates with lender through closing
Brokers are compensated through yield spread premiums (when you take a loan at a higher rate than the best available, the difference goes to the broker) or origination fees paid by the lender or you at closing. In California, brokers must disclose all compensation.
Banks (Direct Lenders)
A bank is a direct lender that originates, funds, and services mortgages. Wells Fargo, Chase, Bank of America, and Citi are large banks. Local banks like Silicon Valley Bank also originate mortgages. Here's how it works:
- You apply directly with the bank's mortgage department
- Bank uses its own underwriting and pricing
- You get the bank's rate and terms (no shopping other lenders)
- Bank either holds the loan or sells it on the secondary market
- Bank services your loan (collects payments)
Banks set pricing based on their cost of funds, risk appetite, and market competition. Some banks are aggressive (lower rates to gain market share), others are passive (higher rates because they have a full customer base).
Credit Unions
Credit unions are not-for-profit financial institutions owned by their members. Many offer mortgages to members. Here's how it works:
- You must be a member (often requires opening an account or working at an employer that sponsors the CU)
- Credit union originates and often services your loan
- Rates are typically competitive because CUs operate on lower margins
- Loan programs are often more limited than banks or brokers
Credit unions excel at conventional, conforming loans for strong borrowers. They often don't offer jumbo loans, FHA/VA program expertise, or portfolio loans for nontraditional borrowers.

The Real Cost Difference: A Bay Area Example
Let's walk through what you actually pay with each type of lender on a real $900,000 loan in Alameda County.
Hypothetical rates to show the math, not an offer or a quote. Figures are interest rate only, not APR; APR includes loan costs and would be higher. Ask for today’s rate and APR.
Scenario: $900,000 Loan, 30-Year Fixed
Large retail bank: Rate 6.50%, Origination 1.0% ($9,000). Total closing costs ~$16,000.
Credit union: Rate 6.375%, Origination 0.5% ($4,500). Total closing costs ~$12,000.
Mortgage Broker (like Chris Granger): Shop 40 lenders, find a wholesale lender at 6.25%, Origination 0.75% ($6,750). Total closing costs ~$13,500.
Monthly payment comparison:
- Bank at 6.50%: $5,689/month
- Credit Union at 6.375%: $5,615/month ($74/month savings)
- Broker at 6.25%: $5,541/month ($148/month savings vs. bank, $74 vs. CU)
30-year cost difference (principal + interest only, not taxes/insurance):
- Bank: $2,047,900
- Credit Union: $2,021,338 (-$26,562)
- Broker: $1,994,924 (-$52,977 vs. bank, -$26,415 vs. CU)
Fold in closing costs and the broker still wins: about $55,000 less than the bank over 30 years ($52,977 in payments plus $2,500 lower closing costs) and about $25,000 less than the credit union ($26,415 in payments minus $1,500 higher closing costs). And those numbers assume the bank and CU rates stay identical every day. In reality, a broker's shopping power means even bigger savings.
When to Use Each Type of Lender
Use a Mortgage Broker When:
- You want the lowest rate possible and are willing to pay for rate shopping
- You're getting a jumbo loan ($1.25M+ in the Bay Area). Brokers dominate this market
- You have complex credit or finances (self-employed, recent bankruptcy, etc.)
- You want personal service and accountability
- You're a repeat buyer or investor and value flexibility
- You're looking at non-traditional programs (portfolio loans, asset-based loans)
Use a Bank When:
- You're a customer already (checking/savings account) and they give you a loyalty discount
- You want simplicity and don't care about rate shopping
- You're doing a simple conventional loan with excellent credit and down payment
- You prefer dealing with a large institution you trust
- You're refinancing a loan you already have with them
Use a Credit Union When:
- You're a member and they offer competitive rates on conventional loans
- You want lower fees and simpler processes
- You're doing a basic conventional purchase with good credit
- You value being part of a not-for-profit institution
Common Myths About Mortgage Brokers
Myth: Brokers Are Less Regulated Than Banks
False. Mortgage brokers in California are regulated by the Department of Real Estate (DRE) Mortgage Loan Broker license requirement. Federally, all brokers must be registered with NMLS. Banks are also federally regulated (OCC, FDIC, Fed). Both are heavily regulated; the regulations are just different.
Myth: Using a Broker Hurts My Credit More Than a Bank
False. Whether you apply with a broker or a bank, there's one hard credit inquiry. If a broker shops you with multiple lenders within a 14-day window, credit scoring models treat it as a single inquiry. After 14 days, additional inquiries are separate. This is industry standard across all lending.
Myth: Brokers Take Longer Than Banks
False. Brokers typically close in 5-7 days, same as banks. Some banks are slower (10-14 days) due to internal processes. Speed depends on document preparation and appraisal turnaround, not on broker vs. bank.
Myth: Brokers Always Charge More
False. Brokers can charge origination fees (0.5-1.5%) but often compensate you with better rates. Wholesale pricing is often a fraction of a point below retail, and on most loans that lower rate more than offsets the origination fee (see the worked example above).
How to Choose Your Lender: Key Questions
- What's the total cost including rate, origination fees, and all closing costs? Get a Loan Estimate from each lender and compare total out-of-pocket at closing.
- What's your customer service quality? Can you reach someone if you have questions? Are they responsive? Check Google reviews and ask for references.
- Are they licensed and regulated? Verify NMLS license status at nmlsconsumeraccess.org. For brokers in CA, check DRE license.
- What loan programs do they offer? Make sure they can do your specific loan type (VA, FHA, jumbo, etc.).
- How transparent are they about pricing? Can they explain origination fees, lender credits, and yield spreads?
All three types of lenders (brokers, banks, and credit unions) can get you a mortgage. The key difference is: brokers shop 100+ lenders to find you the best rate; banks offer only their own rates; credit unions offer competitive rates for members on basic loans. For most Bay Area borrowers, a broker's rate advantage (often 0.25-0.5% lower) saves tens of thousands of dollars over the loan term. For simple scenarios or bank customers with loyalty discounts, a bank can make sense. Credit unions work best for members doing straightforward conventional loans.
Frequently Asked Questions
What's the difference between a mortgage broker and a bank? +
A mortgage broker is an independent middleman who shops 100+ lenders on your behalf and gets paid when your loan closes. A bank is a direct lender that only offers its own mortgage products and rates. Brokers have access to more programs and rates; banks control the entire process but are limited by their own offerings.
Do mortgage brokers cost more than banks? +
Not necessarily. Brokers and banks both charge origination fees, typically 0.5-1.5% of the loan amount. The real difference is lender selection and negotiation power. A broker can find a lender with better rates or programs for your specific situation. On a $1M loan, the right lender choice saves $5,000-15,000+.
Can I trust a mortgage broker? +
Qualified brokers are licensed and regulated by state authorities (in California: DRE Mortgage Loan Broker) and federally (NMLS). Always verify your broker's license and ask for references. The best brokers have testimonials from past clients and transparent fee structures. A broker's profit depends on your satisfaction; they succeed when you get a great loan.
Should I shop multiple lenders even if I use a broker? +
A good broker shops 100+ lenders internally, so you don't need to. However, you can still request rate quotes from 1-2 others if desired. Multiple hard credit inquiries within 14 days count as a single inquiry for credit scoring purposes. Most borrowers are best served by one strong broker who shops comprehensively.
What are the pros and cons of using a credit union for mortgages? +
Credit unions often have competitive rates and lower fees because they're not-for-profit. However, they serve members only, have limited loan programs, and may not offer jumbo loans or specialized products. Best for conventional, conforming loans; less suitable for FHA, VA, or jumbo mortgages.
