12 Ways to Get a Lower Mortgage Rate

Mortgage rates have remained elevated in recent years compared with the ultra-low levels seen earlier in the decade, and even a difference of 0.5% to 1% can translate into tens of thousands of dollars in extra interest over the life of a 15- or 30-year loan. The good news is that borrowers have many tools to secure a better rate, reduce monthly payments, and lower total borrowing costs.

This guide walks through 12 practical strategies to help you qualify for a lower mortgage rate, whether you are a first-time homebuyer or considering a refinance.

Why Mortgage Rates Matter So Much

Your mortgage rate determines how much interest you pay on the money you borrow. Because mortgages are typically large balances repaid over long periods, even small rate changes significantly impact total cost.

Loan AmountTermRateApprox. Monthly Principal & InterestTotal Interest Paid
$300,00030 years6.5%≈ $1,896≈ $382,600
$300,00030 years5.5%≈ $1,703≈ $313,000

In this simplified example, a 1 percentage point difference in the rate reduces the monthly payment by about $190 and saves nearly $70,000 in interest over 30 years. That is why it pays to be strategic when shopping for a mortgage.

1. Save for a Larger Down Payment

Your down payment reduces the loan amount you need to borrow and improves your overall risk profile from the lender’s perspective. A larger down payment can lead to:

  • Lower monthly payments, because you are borrowing less.
  • Better interest rates, since lenders often reward lower loan-to-value (LTV) ratios.
  • The possibility of avoiding mortgage insurance on conventional loans if you put down at least 20%.

For conventional mortgages backed by Fannie Mae and Freddie Mac, pricing adjustments are partly based on credit score and LTV ratio; lower LTVs generally qualify for more favorable pricing and rates. While you do not necessarily need 20% down, crossing key thresholds (such as 5%, 10%, 15%, and 20%) can improve the terms you are offered.

Tips to boost your down payment:

  • Set up an automatic savings transfer into a dedicated home fund.
  • Direct work bonuses, tax refunds, or windfalls straight into savings.
  • Temporarily cut discretionary expenses to accelerate your savings timeline.

2. Buy Discount Points

Paying part of your interest upfront through discount points can reduce your interest rate for the entire loan term. This strategy is especially useful if you plan to stay in the home long enough to reach the break-even point.

How Discount Points Work

  • One discount point generally costs 1% of the loan amount.
  • Each point typically reduces the interest rate by about 0.25%, although the exact amount varies by lender and market conditions.
  • You pay this fee at closing as part of your settlement costs.

For example, on a $300,000 loan, one point costs $3,000 and might reduce your rate from 6.75% to 6.5%. Over time, the lower monthly payment can more than offset the upfront cost, particularly if you stay in the home for many years.

Key considerations:

  • Calculate the break-even period: divide the cost of points by the monthly interest savings.
  • Buying points generally makes more sense if you expect to keep the loan beyond that break-even timeline.
  • If you might sell or refinance in a few years, discuss alternatives with your lender, including temporary buydown options.

3. Shop Around and Compare Lenders

Different lenders can quote noticeably different rates and fees to the exact same borrower. Research from the Consumer Financial Protection Bureau (CFPB) shows that borrowers who compare multiple offers often save substantial amounts over the life of their mortgages.

To maximize your savings:

  • Request quotes from at least three to five lenders, including banks, credit unions, and online lenders.
  • Ask each for a standardized Loan Estimate so you can compare rates, points, and closing costs line by line.
  • Look at the annual percentage rate (APR), which includes both the interest rate and certain fees, for a more complete cost comparison.

Use competing offers as leverage. Lenders may be willing to match or beat a competitor’s rate or reduce fees to win your business, especially in slower markets.

4. Consider Shorter Loan Terms

Shorter-term mortgages—such as 10-, 15-, or 20-year loans—usually come with lower interest rates than traditional 30-year loans. Lenders face less long-term risk, so they often charge less to compensate for uncertainty over time.

According to historical rate comparisons, average rates on 15-year fixed mortgages are often between 0.25% and 0.75% lower than 30-year rates. The trade-off is that monthly payments are higher because the principal is repaid more quickly.

Pros of shorter terms:

  • Lower interest rate.
  • Much less total interest paid over the life of the loan.
  • Faster equity buildup and earlier full ownership.

Cons of shorter terms:

  • Higher monthly payments, which can impact your budget.
  • Less flexibility if your income fluctuates or expenses rise.

One hybrid approach is to choose a 30-year term for flexibility but make extra principal payments when possible. This can mimic some of the benefits of a 15- or 20-year loan without the obligation of a higher required payment.

5. Explore Different Mortgage Types

Choosing the right mortgage type can also help you secure a better rate or reduce upfront costs.

Fixed-Rate vs. Adjustable-Rate Mortgages (ARMs)

With a fixed-rate mortgage, your rate and principal-and-interest payment stay the same for the life of the loan. With an adjustable-rate mortgage (ARM), your rate is fixed for an initial period (such as 5, 7, or 10 years) and then adjusts at set intervals.

Mortgage TypeTypical Initial RateBest For
Fixed-RateHigher than comparable ARMLong-term owners who value payment stability
ARMLower initial rate, adjustable laterBorrowers planning to move or refinance before adjustments

If you expect to sell or refinance within a few years, an ARM’s lower introductory rate could reduce your costs during the time you actually hold the loan. However, you must be comfortable with the potential for higher rates later, and you should review the ARM’s terms carefully, including adjustment caps and index.

6. Improve Your Credit Score

Your credit score is one of the most important factors lenders use to determine your rate. Higher scores are associated with lower default risk, so borrowers with excellent credit typically qualify for significantly lower rates.

Even a modest improvement in your score—sometimes as little as 20 points—can move you into a more favorable pricing tier and reduce your rate.

Strategies to strengthen your credit before applying:

  • Pay every bill on time; payment history is the largest credit score factor.
  • Reduce revolving credit balances to keep utilization below about 30% of your available limit.
  • Avoid opening new credit cards or loans shortly before applying for a mortgage.
  • Check free credit reports and dispute any errors with the bureaus.

Because it can take several months for improvements to reflect in your score, start this process well before you begin house hunting when possible.

7. Reduce Your Overall Debt Load

Lenders also look closely at your debt-to-income (DTI) ratio, which compares your total monthly debt payments to your gross monthly income. Lower DTI ratios generally indicate that you have more room in your budget to handle new mortgage payments, which can help you qualify and sometimes secure better pricing.

To improve your DTI before applying:

  • Pay down high-interest credit cards and personal loans.
  • Avoid financing large purchases (like vehicles) right before your mortgage application.
  • Consider consolidating debt into lower-rate products if this reduces payments and total cost.

Reducing your other obligations not only helps you look better on paper but also gives you more financial flexibility once you become a homeowner.

8. Negotiate Lender Fees

While your interest rate is critical, the fees you pay at closing also affect your real cost of borrowing. Many of these charges are at least somewhat negotiable, particularly when you have strong credit or competing offers in hand.

Common negotiable items can include:

  • Origination fees
  • Application or underwriting fees
  • Discount point pricing (in some cases)

To negotiate effectively:

  • Get detailed, written estimates from multiple lenders.
  • Ask your preferred lender if they can match or beat competing quotes.
  • If you have a long-standing relationship with a bank or credit union, inquire about relationship discounts or reduced fees.

In addition, it may be possible to negotiate seller concessions, where the seller agrees to pay part of your closing costs. This does not directly lower your rate but can reduce the cash needed at closing and allow you to allocate more funds toward discount points, which can lower the rate.

9. Lock In Your Rate at the Right Time

Mortgage rates can change daily and sometimes move significantly between the time you apply and the day you close. A rate lock is an agreement with your lender to hold a specified rate for a defined period, such as 30, 45, or 60 days.

Key features of rate locks:

  • Some lenders offer basic locks at no charge; others may charge a fee or adjust the rate slightly.
  • Longer lock periods generally cost more than shorter ones.
  • In volatile markets, locking can protect you from sudden rate spikes.

The main trade-off is that if rates fall during your lock period, you might miss out on a lower rate. Some lenders offer float-down or re-lock options that allow one-time adjustments if rates drop; ask about these features before committing.

10. Sign Up for Autopay

Many mortgage lenders and servicing institutions provide a small rate discount when you enroll in automatic payments from a linked bank account. Typical discounts might be around 0.125 percentage points, which can still save you money over the long run.

Beyond the potential rate reduction, autopay helps you:

  • Reduce the risk of late payments and associated fees.
  • Maintain a positive payment history, which supports your credit score.

Ask your lender whether automatic payments or linking a checking account could qualify you for a rate or fee discount as part of a broader relationship pricing package.

11. Research First-Time Homebuyer and Assistance Programs

Federal, state, and local programs often help qualified borrowers—especially first-time buyers—obtain mortgages with lower rates, reduced fees, or down payment assistance.

Examples include:

  • FHA loans, insured by the Federal Housing Administration, which may offer more flexible credit and down payment requirements.
  • VA loans for eligible veterans, service members, and certain surviving spouses, often with highly competitive rates and no down payment requirement.
  • USDA loans for eligible rural properties and borrowers, which may offer low or no down payment options.
  • State housing finance agency programs that provide down payment assistance or below-market rate loans.

Visit your state or local housing agency website, or consult HUD’s resources, to identify programs for which you might qualify. These options can substantially reduce both your upfront and ongoing costs of homeownership.

12. Plan to Refinance if Rates Fall

Market conditions change over time. If you need to buy a home when rates are relatively high, you can still benefit later by refinancing if rates decline and you meet lender qualifications. Refinancing replaces your existing mortgage with a new one, ideally at a lower rate, which decreases your monthly payment and total interest costs.

When evaluating a potential refinance, consider:

  • The difference between your current rate and today’s refinance rate.
  • Closing costs and how long it will take to recover them through monthly savings.
  • Whether changing the term (for example, from 30 years to 20 years) aligns with your financial goals.

Many homeowners use a buy-now, refinance-later strategy: they purchase the home at current rates to begin building equity and then refinance if and when rates move meaningfully lower.

Frequently Asked Questions (FAQs)

Q: How much can a 0.5% lower mortgage rate save me?

A: On a large, long-term loan, a 0.5% rate reduction can save tens of thousands of dollars over the life of the mortgage, depending on balance and term. The exact amount depends on your loan size and repayment schedule, so using an amortization calculator is helpful.

Q: Is it worth waiting for rates to drop before buying a home?

A: Waiting for lower rates is a risk, because home prices and rents may continue to rise. Many borrowers focus instead on finding a suitable home they can afford now, locking in the best rate available, and planning to refinance if rates decline later.

Q: How long does it take to improve my credit score enough to impact my rate?

A: Some improvements, like paying down revolving debt or correcting errors on your report, can influence your score within a few billing cycles, while building a long-term on-time payment history takes longer. Starting several months before applying for a mortgage gives you more room to see positive changes.

Q: Should I prioritize a bigger down payment or buying discount points?

A: Both strategies can reduce your total costs, but they work differently. A larger down payment lowers your loan amount and may eliminate mortgage insurance, while discount points specifically lower your interest rate. The best choice depends on your cash reserves, time horizon in the home, and eligibility for programs that might reduce insurance or closing costs.

Q: How many lenders should I get quotes from?

A: Many experts recommend collecting at least three to five written quotes, including from different types of institutions such as banks, credit unions, and online lenders. Comparing standardized Loan Estimates side by side helps you identify the best combination of rate, fees, and overall terms.
