The best bank for your mortgage depends on what you need to pay for and what kind of support matters to you
There is no single "best" bank for mortgages because different banks offer different things. A bank that gives you the lowest interest rate might have slow customer service. A bank with excellent phone support might charge higher fees. A bank that specializes in mortgages for people with lower credit scores might not offer the fastest closing. The right choice depends on which of these things matter most to your situation.
Start by understanding what you are actually comparing: the interest rate (the percentage you pay to borrow), the origination fee (what the bank charges to process your loan), the closing costs (all the fees at the end), and the customer service (how straightforward it is to reach someone when you have questions). Most people focus only on the interest rate, but a bank with a slightly higher rate and lower fees can cost you less money overall.
Key Takeaways
- Interest rate, origination fees, and closing costs all affect your total cost — comparing only the rate can hide hundreds or thousands of dollars in other fees.
- Large national banks, credit unions, and online lenders each have different strengths: national banks offer consistency, credit unions often have lower fees, and online lenders often have lower rates but less phone support.
- Getting a loan estimate from at least three lenders lets you compare apples to apples, because they must all use the same form and disclose the same costs.
- Your credit score, down payment size, and the type of property affect which banks will work with you and what rate they will offer.
- The bank that approves you fastest is not always the bank that costs you least — approval speed and cost are separate things.
What actually costs you money in a mortgage
When you compare banks, you are comparing four main costs. The interest rate is what you pay yearly to borrow the money — a 6% rate on a $300,000 loan costs you roughly $18,000 in the first year alone. The origination fee is what the bank charges to process your process, usually 0.5% to 1% of the loan amount. The closing costs include appraisal fees, title insurance, property taxes, and other expenses — these typically run 2% to 5% of the loan amount. The discount points are an optional fee you can pay upfront to lower your interest rate.
A bank advertising a 5.5% rate might charge you $6,000 in origination and closing costs. Another bank with a 5.75% rate might charge only $3,000. Over 30 years, the second bank could cost you less money even though the rate is higher. This is why you need to see the full picture, not just the advertised rate.
You will receive a Loan Estimate from each bank within three business days of explore. This is a standardized form that shows the interest rate, all fees, estimated monthly payment, and total cost over the life of the loan. Use this form to compare banks fairly — it is the only document where all banks must disclose the same information in the same order.
National banks versus credit unions versus online lenders
National banks like Chase, Bank of America, and Wells Fargo have branches everywhere, which means you can walk in and talk to someone in person. They offer mortgages to people with a wide range of credit scores and financial situations. The trade-off is that their rates and fees are often higher than smaller competitors, because they have more overhead and they do not need to compete as hard for your business.
Credit unions are member-owned cooperatives that often charge lower origination fees and closing costs than national banks. If you are a member of a credit union, ask them about mortgages — many offer rates competitive with online lenders and better customer service than national banks. The limitation is that credit unions vary widely in size and lending capacity. A small credit union might not have mortgage specialists or might cap the loan amount they will offer.
Online lenders like Rocket Mortgage, Better.com, and LoanDepot often advertise the lowest rates because they have no physical branches and lower overhead. They move fast — some can close in two weeks. The catch is that most online lenders have minimal phone support, and if something goes wrong or you have questions, you may spend hours in a chat queue. Online lenders also tend to work best if your financial situation is straightforward: stable income, good credit, and a conventional loan type.
How your credit score and down payment affect your options
Your credit score is a number between 300 and 850 that tells banks how reliably you have paid debts in the past. Most banks require a score of at least 620 to offer you a mortgage, but the best rates go to people with scores above 740. If your score is below 620, many national banks and online lenders will not work with you. Credit unions and banks that specialize in mortgages for people rebuilding credit may still offer loans, but at higher rates.
Your down payment — the money you pay upfront — also changes which banks will work with you and what they will charge. If you can put down 20% or more, most banks will compete for your business and offer you their best rates. If you can only put down 3% to 5%, fewer banks will work with you, and those that do will charge higher rates and require you to pay mortgage insurance (a monthly fee that protects the bank if you stop paying). If you are putting down less than 20%, ask each bank what their mortgage insurance costs — this can vary significantly and is straightforward to miss.
Getting loan estimates and comparing them side by side
Once you have identified three to five banks or lenders you want to compare, contact each one and ask for a Loan Estimate. You do not have to formally explore — you can ask for an estimate based on your financial information. Each bank must send you the estimate within three business days, and it is free.
When you receive the estimates, look at the Loan Estimate form itself, not the bank's marketing materials. The form has three pages. Page 1 shows the loan amount, interest rate, and monthly payment. Page 2 shows all the fees broken down by category. Page 3 shows the total amount you will pay over the life of the loan. Compare the same numbers across all three estimates: the interest rate, the origination fee, the appraisal fee, the title insurance cost, and the total closing costs.
Be aware that some fees can change between the estimate and closing, but the bank must notify you of changes in writing. The origination fee, interest rate, and most closing costs should stay the same if your financial situation does not change. Property taxes and homeowners insurance estimates may shift slightly.
Speed versus cost: what to prioritize
Some banks close mortgages in 10 days. Others take 45 days. If you are in a competitive real estate market and need to close quickly to win a bidding war, speed matters. If you have time and want to save money, cost matters more. These are not the same thing — the fastest bank is rarely the cheapest.
Ask each bank how long their average closing takes and whether they have any delays in their process. Online lenders are usually fastest. Credit unions are often slower because they have fewer staff. National banks fall somewhere in the middle. If speed is critical, prioritize banks that have closed mortgages in your state recently and have dedicated closing teams.
If cost is your priority, do not rush. Take the full time to compare estimates, ask questions about fees, and negotiate. Some banks will lower their origination fee or cover some closing costs if you ask, especially if you have good credit and a large down payment.
Red flags and questions to ask before you commit
Before you choose a bank, ask these questions: What happens if interest rates drop — can I lock in a lower rate? What is your process if the appraisal comes in lower than the purchase price? Do you have a loan officer I can call, or is everything online? What is your average closing time, and what causes delays? Are there any fees that are not on the Loan Estimate?
Be cautious of banks that pressure you to decide quickly, advertise rates that seem too good to be true, or refuse to put their terms in writing. Be cautious of banks that quote you a rate without asking about your credit score, down payment, or the type of property — rates vary based on these factors, and a quote that does not account for them is not real.
If a bank charges a fee that other banks do not charge, ask why. Some fees are legitimate and necessary. Others are padding. A good loan officer can explain every line on your Loan Estimate.
Frequently Asked Questions
Should I use the bank where I have my checking account?
Not necessarily. Banks often give discounts to existing customers, but the discount is usually small — maybe 0.25% off the interest rate or $200 off closing costs. Compare their Loan Estimate against at least two other banks before deciding. The discount is only worth it if their total cost is competitive.
What if I have bad credit or a low down payment?
Start with credit unions and banks that specialize in mortgages for people with lower credit scores or smaller down payments. FHA loans, which are backed by the federal government, allow down payments as low as 3.5% and work with credit scores as low as 580. Ask whether each bank offers FHA loans and what their rates and fees are for that product.
Can I lock in an interest rate before I find a house?
You can get a pre-approval letter that shows a rate, but that rate is usually only good for 30 to 60 days. Once you find a house and make an offer, you will lock in your actual rate at that time. Locking too early can cost you money if rates drop before you close.
What if the bank's appraisal comes in lower than what I am paying for the house?
Ask the bank upfront what their process is if this happens. Some banks will renegotiate with you. Some will require you to put down more money. Some will walk away from the deal. Knowing this in advance helps you decide whether to work with that bank.
Do I have to use the bank's title company and appraiser?
No. The bank will recommend vendors, but you can shop around for title insurance and appraisals. Get quotes from at least two title companies — prices vary. For the appraisal, the bank usually orders it, but you can ask whether you can use a different appraiser if you find one cheaper.
