The best mortgage rate for you depends on what you can afford to pay upfront, how long you plan to stay in the home, and which lender you shop with—not on finding some hidden "best" rate that exists everywhere.

Mortgage rates change daily and vary between lenders. A rate that is lowest today might not be lowest tomorrow. More importantly, the lowest advertised rate often comes with conditions: you might need to pay points (an upfront fee that lowers your rate), have a very high down payment, or accept a shorter loan term. The "best" rate is the one that fits your actual situation—your budget, your timeline, and what you can afford to pay both now and over the life of the loan.

The process has three parts: understanding what moves rates, knowing what lenders to compare, and doing the actual comparison in a way that lets you see apples-to-apples numbers.

Key Takeaways

  • Mortgage rates vary between lenders by as much as 0.5 percent, so comparing at least three lenders can save you tens of thousands of dollars over the life of the loan.
  • The lowest rate is not always the best deal if it comes with points or other upfront costs that you cannot afford or will not recoup before you sell.
  • Your credit score, down payment size, loan type, and loan term all affect the rate you are offered, so improving any of these before you shop can lower your rate.
  • When you compare rates, ask each lender for a Loan Estimate that shows the interest rate, the annual percentage rate (APR), and all closing costs so you can compare the true cost, not just the rate number.

What actually changes your mortgage rate

Your rate is not set by a central authority. It is set by the lender based on several factors about you and the loan itself. The most important are your credit score, your down payment, the loan type (conventional, FHA, VA, or USDA), the loan term (15 years, 30 years, or other), and current market conditions.

A higher credit score gets you a lower rate. A larger down payment gets you a lower rate. A shorter loan term usually comes with a lower rate. A conventional loan (not backed by a government agency) often has a lower rate than an FHA loan, which insures the lender against your default. These are not negotiable—they are how lenders price risk. But they are also things you can sometimes change before you shop. If your credit score is below 700, paying down debt or disputing errors on your credit report before you apply can move your rate down by 0.25 to 0.5 percent. If your down payment is below 20 percent, saving another few thousand dollars to reach 20 percent can eliminate private mortgage insurance (PMI) and lower your rate.

Market conditions—the broader economy, the Federal Reserve's actions, inflation—move all rates up or down together. You cannot control these, but you can watch them. When rates are rising, locking in a rate sooner is usually better. When rates are falling, waiting a few days might help, though no one can predict the direction with certainty.

Which lenders to compare

Rates vary between lenders. The same borrower with the same credit score and down payment might be offered 6.5 percent at one bank and 6.0 percent at another. This is why comparing at least three lenders is standard practice. Over a 30-year loan, a 0.5 percent difference costs you roughly $100 per month on a $300,000 loan—or $36,000 over the life of the loan.

You have several types of lenders to choose from: banks (Wells Fargo, Chase, Bank of America), credit unions (which often offer lower rates to members), mortgage brokers (who work with multiple lenders and can shop on your behalf), and online lenders (Rocket Mortgage, Better.com, LoanDepot). Banks and credit unions are straightforward—you call or visit and they quote you. Mortgage brokers can be faster if you have a complex situation (self-employed, recent job change, lower credit score) because they know which lenders are most likely to approve you. Online lenders are often fastest for straightforward applications but may have higher fees.

Start with your own bank or credit union if you have a relationship there—they sometimes offer member discounts. Then get quotes from at least two other sources: another bank, a credit union if you are not already a member, or a broker. Do this within a two-week window so the rate quotes are comparable and your credit inquiries count as a single inquiry for credit-scoring purposes.

How to compare rates without getting confused

When you get a rate quote, the lender will give you a number—say, 6.25 percent. That number alone is not enough to compare. You need to know whether points are included, what the closing costs are, and what the annual percentage rate (APR) is.

Points are an upfront fee you pay to lower your rate. One point costs 1 percent of the loan amount (so $3,000 on a $300,000 loan) and typically lowers your rate by 0.25 percent. If a lender quotes you 6.0 percent with one point, and another quotes you 6.25 percent with no points, the second lender's rate is actually higher even though the number looks lower. Points only make sense if you plan to stay in the home long enough to recoup the cost through lower monthly payments. On a 30-year loan, you usually break even on points after 5 to 7 years.

The annual percentage rate (APR) is the rate plus the cost of closing fees, expressed as a yearly rate. It is always higher than the interest rate itself. The APR is the number to use when comparing the true cost between lenders, because it includes both the rate and the fees. If Lender A quotes 6.25 percent with an APR of 6.4 percent and $4,000 in closing costs, and Lender B quotes 6.0 percent with an APR of 6.3 percent and $5,500 in closing costs, Lender B's APR is lower, so the true cost is lower even though the advertised rate is lower by a smaller margin.

Ask each lender for a Loan Estimate. This is a standardized form that shows the interest rate, the APR, all closing costs broken down by type, the monthly payment, and the total amount you will pay over the life of the loan. It is required by law. Compare the APR and the total closing costs across all three Loan Estimates. The lender with the lowest APR is offering you the best deal, assuming you plan to keep the loan for the full term.

When to lock in your rate

Once you have chosen a lender and received a Loan Estimate, you can lock in your rate. This means the lender guarantees that rate for a set period—usually 30, 45, or 60 days—even if market rates move up. You pay for this may provide: a longer lock period costs more. A 30-day lock is cheaper than a 60-day lock.

Lock in your rate when you are confident in your choice of lender and you have a clear timeline to closing. If you lock too early and rates drop, you are stuck with the higher rate. If you lock too late and rates rise, you may have to pay more or lose the home you are trying to buy. Most people lock in once they have a signed purchase agreement and a clear closing date, usually 30 to 45 days away.

Some lenders offer a rate float-down option, which lets you lock in a rate but still benefit if rates drop before closing. This costs more upfront but gives you flexibility. It is worth asking about if you are uncertain about the direction of rates.

Improving your rate before you shop

If you have time before you apply, a few steps can lower the rate you are offered. Paying down credit card balances lowers your debt-to-income ratio, which lenders use to assess risk. Disputing errors on your credit report can raise your credit score. Saving for a larger down payment (especially reaching 20 percent to avoid PMI) can lower your rate. Waiting to apply until you have been in your current job for at least two years, if you are self-employed or recently changed jobs, can help you may have access to for better rates.

These changes take time—weeks or months—so plan ahead if you can. If you are in a hurry to buy, focus on comparing lenders instead, because the difference between lenders is often larger than the difference you can make by improving your credit in a short timeframe.

Frequently Asked Questions

Does shopping around for rates hurt my credit score?

Multiple rate inquiries within a 14-day window count as a single inquiry for credit-scoring purposes, so shopping around does not meaningfully hurt your score. After 14 days, each new inquiry is counted separately and can lower your score by a few points. This is why lenders recommend getting all your quotes within a two-week window.

What is the difference between a fixed rate and an adjustable rate?

A fixed rate stays the same for the entire loan term—30 years, 15 years, or whatever you choose. An adjustable rate (ARM) starts lower but increases after a set period, usually 3, 5, 7, or 10 years. Fixed rates are simpler and more predictable. ARMs can save money if you plan to sell before the rate adjusts, but they carry risk if you stay in the home longer.

Can I negotiate my mortgage rate with a lender?

The interest rate itself is not negotiable—it is set by the lender based on market conditions and your financial profile. But closing costs sometimes are. If one lender's rate is lower but their closing costs are higher, you can ask them to reduce the costs or ask a competing lender to match the rate and lower the costs. Lenders compete on closing costs more than on rates.

What if I have bad credit—can I still get a good rate?

You can still get a mortgage with a credit score below 620, but the rate will be higher. FHA loans allow scores as low as 580. If your score is low, focus on improving it before you apply if you have time, or look for lenders who specialize in lower-credit borrowers. Credit unions sometimes offer better rates to members with lower scores than banks do.

Should I get a 15-year or 30-year mortgage?

A 15-year mortgage has a lower interest rate and you pay less interest overall, but the monthly payment is much higher. A 30-year mortgage has a higher rate and more total interest, but the monthly payment is lower and more affordable for most people. Choose based on what monthly payment you can afford, not on which saves more interest. If you can comfortably afford the 15-year payment, it is usually the better choice.
