The best mortgage rate for you depends on your credit score, down payment size, loan type, and how long you plan to stay in the home

A mortgage rate is not fixed across all lenders or borrowers. Two people applying on the same day can receive different offers based on their financial profile. Your credit score, the size of your down payment, whether you choose a fixed or adjustable rate, and the length of your loan all move the rate up or down. A lender also prices risk differently — one may charge 6.5% while another charges 6.2% for the same borrower.

The gap between a good rate and a poor one costs real money over 30 years. A 0.5% difference on a $300,000 loan adds roughly $60,000 to your total interest paid. This is why shopping across multiple lenders and understanding what moves your rate is worth the time before you sign.

Key Takeaways

  • Your credit score is the single largest factor lenders use to set your rate; scores above 740 typically receive the best offers, while scores below 620 face significantly higher rates.
  • Getting pre-approved by at least three different lenders lets you compare actual rate quotes and lock in the lowest one before you make an offer on a home.
  • A larger down payment (20% or more) removes mortgage insurance costs and often qualifies you for a lower rate than a smaller down payment would.
  • Paying points — an upfront fee equal to a percentage of the loan amount — can lower your rate if you plan to stay in the home long enough to recoup the cost.
  • Your rate can shift between pre-approval and closing, so locking your rate in writing protects you from market swings during the loan process.

Check and improve your credit score before you shop

Lenders pull your credit report and score to determine the interest rate they offer you. The higher your score, the lower your rate. Most lenders use FICO scores, which range from 300 to 850. Scores above 740 typically receive the best published rates. Scores between 620 and 739 face progressively higher rates. Scores below 620 may be denied outright or offered rates 2% to 3% higher than the best available.

Before you contact a lender, pull your own credit report from AnnualCreditReport.com, the only free source authorized by federal law. Check for errors — a missed payment that was not yours, an account you never opened, or a balance reported incorrectly. Dispute errors directly with the credit bureau (Equifax, Experian, or TransUnion) in writing. Corrections can take 30 to 45 days but can raise your score enough to move you into a better rate bracket.

If your score is below 740, paying down existing credit card balances before you apply can help. Lenders look at your credit utilization — the percentage of your available credit you are using. Bringing that below 30% can raise your score by 10 to 50 points in some cases. Paying off collections or late payments will not erase them from your report, but they age and matter less over time.

Get pre-approved by at least three lenders

Pre-approval is a lender's written statement of how much they will lend you and at what rate, based on your financial documents. It is not a may provide, but it is a real offer. The process takes one to three days and requires your recent pay stubs, tax returns, bank statements, and employment verification. A pre-approval does not affect your credit score — lenders use a soft inquiry that does not show up as a hard pull.

Contact at least three lenders: a traditional bank, a mortgage broker, and an online lender. Banks include Wells Fargo, Chase, and Bank of America. Mortgage brokers like Loan Depot or Better.com shop multiple wholesale lenders on your behalf. Online lenders like Rocket Mortgage or LendingTree operate entirely online and often move faster. Each will give you a Loan Estimate within three business days of your application. This document shows the interest rate, points, closing costs, and monthly payment side by side, so you can compare directly.

Do not apply to more than three lenders in a short window. Multiple hard inquiries within 14 to 45 days count as one inquiry for credit scoring purposes, but lenders see each application separately and may view too many as a sign you are desperate or unstable. Three is enough to find a competitive offer without raising red flags.

Understand how down payment size affects your rate

A larger down payment lowers your rate because it reduces the lender's risk. If you put down 20% or more, you avoid mortgage insurance (PMI), which is an extra monthly fee that protects the lender if you default. Removing that cost alone can lower your rate by 0.25% to 0.5%. Lenders also offer better rates to borrowers with more skin in the game.

The difference is measurable. A borrower with a 3% down payment might receive a rate of 6.8%, while the same borrower with 20% down might receive 6.4%. Over 30 years on a $300,000 loan, that 0.4% difference costs roughly $48,000 in additional interest. If you have the savings, delaying your purchase to save for a larger down payment can pay for itself.

If you cannot reach 20% down, aim for at least 10%. The rate improvement from 3% to 10% is usually larger than from 10% to 20%. Below 3%, rates climb steeply. If you are stuck with a small down payment, focus on improving your credit score and shopping multiple lenders — those moves may offset the rate penalty more than waiting to save another few thousand dollars.

Decide between a fixed rate and an adjustable rate

A fixed-rate mortgage locks your interest rate for the entire loan term — 15, 20, or 30 years. Your monthly payment never changes. This is the most common choice and the safest if you plan to stay in the home for more than five years. Fixed rates are higher than the starting rate on an adjustable mortgage, but you know exactly what you will pay.

An adjustable-rate mortgage (ARM) starts with a lower rate that is fixed for a set period (typically 3, 5, 7, or 10 years), then adjusts annually based on market conditions. If rates rise, your payment rises. If rates fall, your payment falls. ARMs are cheaper upfront but risky if you stay past the adjustment period or if rates spike. Most borrowers choose fixed rates because the certainty is worth the higher starting rate.

When comparing quotes, make sure you are comparing the same loan type. A 5/1 ARM (fixed for 5 years, then adjustable) will always show a lower rate than a 30-year fixed on the same day, but they are not the same product. Ask each lender for both options so you can see the actual difference.

Consider paying points to lower your rate

A discount point is an upfront fee you pay at closing to reduce your interest rate. One point costs 1% of your loan amount. On a $300,000 loan, one point costs $3,000 and typically lowers your rate by 0.25%. Two points cost $6,000 and lower your rate by roughly 0.5%. The lower rate means a lower monthly payment for the life of the loan.

Paying points makes sense only if you stay in the home long enough to recoup the upfront cost through monthly savings. If one point costs $3,000 and saves you $75 per month, you break even after 40 months (about 3.3 years). If you plan to sell or refinance within five years, paying points is usually a waste. If you plan to stay 10 years or longer, points often pay for themselves and then some.

Ask each lender for a rate sheet that shows the rate at zero points, one point, and two points. This lets you calculate the break-even point for your situation. Some lenders also offer lender credits — the opposite of points — where the lender pays some of your closing costs in exchange for a slightly higher rate. This is useful if you have limited cash at closing.

Lock your rate in writing before closing

Once you have chosen a lender and agreed on a rate, ask for a rate lock in writing. This freezes your rate for a set number of days — typically 30, 45, or 60 days — so that market swings do not change your offer before you close. Without a lock, the lender can adjust your rate up if market rates rise between pre-approval and closing.

Rate locks are free, but longer locks sometimes cost slightly more. A 30-day lock is standard if you expect to close in 30 days. A 60-day lock costs a bit more but protects you if the closing is delayed. Ask your lender what happens if you need to extend the lock — some allow one free extension, others charge a fee.

Read the lock agreement carefully. Some locks are float-down locks, which let you take a lower rate if the market drops before closing. Others are lock-and-shop locks, which let you lock a rate but still shop other lenders during the lock period. Standard locks do not allow either. Understand what you are locking before you sign.

Shop for the lowest closing costs, not just the lowest rate

Two lenders may offer the same interest rate but different closing costs. Closing costs include origination fees, appraisal fees, title insurance, and other charges. They typically range from 2% to 5% of the loan amount. A lender with a 0.1% lower rate but $2,000 higher closing costs may cost you more over time, especially if you plan to sell within five years.

Use the Loan Estimate each lender provides to compare total cost, not just the rate. Add the rate and the closing costs together. A lender charging 6.2% with $4,000 in costs is not automatically better than one charging 6.4% with $2,000 in costs — it depends on how long you stay. Ask each lender to break down their closing costs line by line. Some costs are negotiable; others are set by third parties like the appraiser or title company.

Federal law requires lenders to provide a Closing Disclosure at least three days before closing. This is your final accounting of all costs. Review it against your Loan Estimate. If costs have changed significantly, ask why and whether you can negotiate them down or switch lenders if you have not locked your rate yet.

Frequently Asked Questions

Does shopping for rates hurt my credit score?

Multiple mortgage inquiries within 14 to 45 days count as a single inquiry for credit scoring purposes, so shopping three lenders in one week has minimal impact. Your score may drop 5 to 10 points temporarily, but it recovers within a few months. The rate savings from shopping usually far outweigh the temporary score dip.

Can I negotiate my rate after I get a pre-approval?

Yes. If another lender offers a lower rate, bring that quote to your current lender and ask them to match it or beat it. Lenders have some flexibility, especially if you have a strong financial profile. This is called a rate match or price match. Do this before you lock your rate, because once locked, you cannot shop further without breaking the lock.

What is the difference between APR and interest rate?

The interest rate is the percentage you pay on the loan itself. The APR (annual percentage rate) includes the interest rate plus closing costs and points, expressed as an annual rate. The APR is always higher than the interest rate. Use APR to compare total cost across lenders, but use the interest rate to understand your monthly payment.

Should I refinance if rates drop after I close?

Refinancing makes sense if the new rate is at least 0.5% lower than your current rate and you plan to stay in the home long enough to recoup the closing costs (usually three to five years). If rates drop 0.25%, refinancing usually costs more than you save. Use an online refinance calculator to compare your current loan against the new offer before you apply.

Can I get a better rate if I use the same bank for my checking account?

Some banks offer small rate discounts (0.125% to 0.25%) to customers who have a checking or savings account with them. These discounts are real but small. They should not be your primary reason to choose a lender. A 0.5% rate difference from a competitor matters far more than a 0.125% loyalty discount.
