Mortgage rates vary by lender, loan type, and your financial profile—not by which bank has the "best" rate overall

There is no single bank with the best mortgage rates for everyone. The rate you receive depends on what you are borrowing, how long you want to borrow it for, how much you put down, your credit score, your debt-to-income ratio, and current market conditions. A rate that is competitive for a 30-year fixed loan might not be the best for a 15-year fixed or an adjustable-rate mortgage. A bank offering 6.5% to someone with a 750 credit score might offer 7.2% to someone with a 620 score.

What matters is understanding what moves a rate up or down, then comparing actual quotes from multiple lenders using the same loan terms. This means getting quotes from at least three to five places—banks, credit unions, mortgage brokers, and online lenders—all for the same loan amount, term, and down payment percentage.

Key Takeaways

  • Mortgage rates change daily and vary by lender, so comparing quotes from at least three to five sources using identical loan terms is the only way to find your actual best rate.
  • Your credit score, down payment size, debt-to-income ratio, and loan type (fixed vs. adjustable, 15-year vs. 30-year) all affect the rate you are offered, sometimes by a full percentage point or more.
  • Banks, credit unions, mortgage brokers, and online lenders all offer mortgages, and rates differ significantly between them—no single type consistently offers the lowest rates.
  • Lenders quote rates with different discount points and closing costs, so comparing the interest rate alone is not enough; you need to compare the total cost over the life of the loan.
  • Rate locks last 30 to 60 days typically, so once you have quotes, you have a limited window to lock in a rate before it changes.

What actually determines the rate you are offered

Credit score is the single largest factor lenders use to price your rate. A borrower with a 760 score might receive a rate 0.5% to 1% lower than a borrower with a 680 score, all else equal. Lenders publish rate sheets that show the adjustment for each credit score band—typically in 20-point increments from 620 to 780 and above.

Down payment size affects your rate because it changes your loan-to-value ratio (LTV). A 20% down payment usually gets a lower rate than a 10% down payment, which gets a lower rate than a 3% down payment. Loans with less than 20% down require mortgage insurance, which lenders price into the rate or as a separate monthly fee.

Loan type and term matter significantly. A 15-year fixed-rate mortgage typically carries a lower rate than a 30-year fixed, because the lender's risk period is shorter. An adjustable-rate mortgage (ARM) usually starts lower than a fixed rate but adjusts upward after the initial period. A jumbo loan (over the conforming loan limit, which varies by county but is often around $766,000 in 2024) carries a different rate than a conforming loan.

Debt-to-income ratio (your total monthly debt payments divided by your gross monthly income) affects pricing. Lenders typically want this below 43%, and borrowers below 36% often receive better rates. A borrower at 50% DTI might pay 0.25% to 0.5% more.

Where to get quotes and what to compare

Start by requesting quotes from at least three to five sources. Include a traditional bank (Wells Fargo, Bank of America, Chase), a credit union if you are a member, a mortgage broker, and an online lender (Rocket Mortgage, Better, LoanDepot). Tell each one the same details: loan amount, down payment percentage, property type, loan term (15 or 30 years), and whether you want a fixed or adjustable rate.

When you receive quotes, do not compare the interest rate alone. Lenders quote rates with different numbers of discount points—upfront fees you pay to lower the rate. One lender might quote 6.5% with zero points and $3,000 in closing costs. Another might quote 6.25% with 1 point ($7,500) and $2,000 in closing costs. The second sounds better until you calculate the total cost. If you plan to stay in the home for 10 years, the lower rate saves you money. If you plan to sell in 5 years, the first option might cost less overall.

Ask each lender for a Loan Estimate, which is a standardized form that shows the interest rate, APR (annual percentage rate, which includes fees), monthly payment, all closing costs, and the rate lock period. This form makes comparison straightforward because the format is the same across all lenders.

How market conditions and timing affect rates

Mortgage rates move daily based on bond market activity, Federal Reserve policy, and economic data. When the Fed raises interest rates, mortgage rates typically rise. When inflation data comes in lower than expected, rates often fall. A rate that is available on Monday might be 0.125% higher by Wednesday.

This means the "best" rate today is not the best rate next week. Once you have quotes and are ready to move forward, you can lock in your rate, which freezes it for a set period—usually 30, 45, or 60 days. During that lock period, if rates rise, your rate stays the same. If rates fall, you cannot take advantage of the drop (unless you negotiated a "float-down" option, which some lenders offer for a fee).

Locking too early means you might lock in a higher rate than you could get later. Locking too late means rates might rise before you lock. Most borrowers lock when they are within 30 to 45 days of closing, because that is when the rate is most likely to stay stable through the closing date.

Banks vs. credit unions vs. mortgage brokers vs. online lenders

No category consistently offers the lowest rates. Each has trade-offs. Traditional banks (Wells Fargo, Bank of America, Chase) have physical branches and customer service, but their rates are often higher than online lenders because they have higher overhead. They are good if you want to work with someone in person or already bank there.

Credit unions typically offer competitive rates to members and may have lower fees, but you must be a member to borrow. may be able to access varies by credit union—some are open to anyone in a geographic area, others require employment at a specific company or membership in an organization.

Mortgage brokers do not lend their own money; they connect you with lenders and earn a commission. They can shop multiple lenders at once, which saves you time, but their rates are not always lower because they add their fee into the cost. Some brokers are transparent about fees; others bury them in closing costs.

Online lenders (Rocket Mortgage, Better, LoanDepot, Blend) have low overhead and often competitive rates, but customer service is entirely digital. If you need to talk to someone on the phone or have a complex situation, this can be frustrating. They are fastest if your process is straightforward.

What to watch out for when comparing rates

Watch for bait-and-quote tactics, where a lender quotes a very low rate but adds high closing costs or points to make up the difference. Always compare the total cost, not just the rate. A quote of 6.2% with $8,000 in closing costs is not better than 6.5% with $2,000 in closing costs if you are staying in the home for 10 years.

Be aware that some lenders quote rates with conditions you might not meet. A rate of 5.9% might only be available if you have a 760+ credit score, 25% down, and a debt-to-income ratio under 30%. If you do not meet those conditions, the actual rate you receive will be higher. Always ask the lender to quote based on your actual profile, not a best-case scenario.

Do not assume a lower advertised rate means a lower final cost. Some lenders advertise rates without mentioning that they require you to buy discount points or that closing costs are higher. The Loan Estimate will show the true picture, but by then you have already spent time explore. Get the Loan Estimate early in the conversation so you can compare apples to apples.

How to lock in a rate and what happens next

Once you have chosen a lender and received a Loan Estimate you are comfortable with, you can ask to lock the rate. The lender will confirm the lock period (30, 45, or 60 days) and put it in writing. Your rate is now frozen at that level for that period, regardless of market movement.

During the lock period, the lender will order an appraisal, verify your employment and income, and review your credit again. If anything changes—your credit score drops, you lose a job, you miss a payment—the lender can adjust or deny your rate lock. This is rare if you lock close to closing, but it happens.

If the appraisal comes in lower than the purchase price, the lender might require you to put more money down or might adjust the rate. If you are refinancing and rates have fallen significantly, the lender might offer you a lower rate even though you locked a higher one—but they are not obligated to.

Frequently Asked Questions

Can I get a mortgage rate quote without a hard credit pull?

Yes. Most lenders offer a soft inquiry that shows your credit range without affecting your score. This is useful for initial shopping. Once you are ready to move forward with a specific lender, they will do a hard pull, which does affect your score slightly. Multiple hard pulls within 14 days typically count as one inquiry for credit scoring purposes, so shopping around does not significantly harm your score if you do it quickly.

What if rates drop after I lock in?

You are locked in at your rate and cannot change it unless you negotiated a float-down option when you locked. Some lenders offer this for a fee (usually 0.25% to 0.5% of the loan amount), which lets you take advantage of a rate drop during your lock period. If you did not buy this option, you are stuck with your locked rate. You can refinance later if rates drop significantly, but that means new closing costs and a new process.

Do I need to use my bank for a mortgage?

No. You can borrow from any lender, regardless of where you have a checking account. Shopping outside your bank often saves money because banks do not always compete aggressively on mortgage rates. Many people find better rates from credit unions, online lenders, or mortgage brokers than from their primary bank.

What is the difference between APR and interest rate?

The interest rate is what you pay on the borrowed money. The APR (annual percentage rate) includes the interest rate plus closing costs and fees, expressed as an annual rate. It is a more complete picture of the true cost of borrowing. Lenders are required to disclose both on the Loan Estimate, and comparing APRs across lenders is often more useful than comparing rates alone.

How often do mortgage rates change?

Mortgage rates change daily, sometimes multiple times per day, based on bond market activity and economic data. Rates are typically quoted in 0.125% increments (one-eighth of a percent). A rate available in the morning might be 0.25% higher by afternoon. This is why locking in a rate matters—once locked, your rate does not change even if market rates move.
