You cannot control the market, but you control most of what decides whether you get a mortgage with a low interest rate: your credit score, your down payment, the type of loan you choose, whether you pay points, when you lock, and above all how many lenders you compare. Two borrowers buying similar homes on the same day can be quoted rates half a percentage point apart or more, and on a 30-year loan that gap is worth tens of thousands of dollars.
This guide explains how US lenders price mortgages in 2026 and gives you a practical plan for getting the lowest rate you qualify for. It covers credit score tiers, discount points, rate locks, fixed versus adjustable rates and the 45-day shopping window that lets you compare lenders without hurting your credit.
This article is general information, not financial advice. Mortgage rates change daily, so check current averages in Freddie Mac’s weekly survey or the rate tool on consumerfinance.gov before you start.
What Determines Your Mortgage Interest Rate?
Every quote starts with the market: the level of Treasury yields, inflation expectations and investor demand for mortgage bonds. On top of that base, lenders add or subtract pricing adjustments for your personal risk profile. The main ones are:
- Credit score. The single biggest personal factor on conventional loans.
- Loan-to-value ratio (LTV). A bigger down payment means a lower LTV and better pricing. Putting down 20% also avoids private mortgage insurance on conventional loans.
- Loan type. Conventional, FHA, VA and USDA loans are priced differently. VA loans often carry the lowest rates for those who are eligible.
- Loan term. A 15-year loan usually has a noticeably lower rate than a 30-year loan.
- Occupancy and property type. Primary residences get the best rates. Second homes, investment properties, condos and multi-unit homes cost more.
- Loan size. Jumbo loans above the conforming limit ($832,750 in most areas for 2026) are priced separately.
- Debt-to-income ratio (DTI). A high DTI can trigger pricing adjustments or a decline.
How Much Does Your Credit Score Affect Your Rate?
Conventional loans sold to Fannie Mae and Freddie Mac are priced using a grid of loan-level price adjustments based on credit score and LTV. The best pricing is reserved for scores of 780 and above, and costs step up with each 20-point band below that. The table shows the general pattern; actual adjustments depend on your down payment and lender.
| FICO score band | What to expect on a conventional loan | Worth considering |
|---|---|---|
| 780 and above | Best available pricing | Shop on fees and points; you already have top-tier rates |
| 740–779 | Very good pricing, slightly above the best tier | A small score bump before applying may pay off |
| 700–739 | Moderate pricing adjustments | Compare conventional against FHA if your down payment is small |
| 660–699 | Noticeably higher rate or fees; PMI costs more too | FHA often becomes competitive |
| 620–659 | Highest conventional pricing; 620 is the usual minimum | FHA, VA or USDA are usually cheaper |
| Below 620 | Conventional generally unavailable | See our bad-credit home loan guide |
FHA, VA and USDA rates are less sensitive to credit score, which is why they suit borrowers with lower scores, although FHA adds mortgage insurance premiums. If your score is under 620, read how to qualify for a home loan with bad credit.
Quick ways to lift your score before applying
- Pay credit card balances down below 30% of each limit, and below 10% if you can. Utilization updates within a month or so.
- Dispute genuine errors on your reports, which you can check free at AnnualCreditReport.com.
- Do not open new credit, finance a car or co-sign anything in the six months before you apply.

Why Does Shopping Lenders Matter, and What Is the 45-Day Window?
Lenders have different costs, profit targets and appetites for particular loans, so quotes for the same borrower vary widely. Research by the CFPB and Freddie Mac has found that borrowers who get several quotes save meaningful money.
Worried about your credit? Credit scoring models recognize rate shopping. Multiple mortgage inquiries made within a 45-day window are treated as a single inquiry by current FICO models. Some older scoring versions use a 14-day window, so the safest approach is to collect all your quotes within about two weeks.
Get quotes from at least three to five sources across different lender types:
- A large bank or the bank where you already hold accounts, which may offer relationship discounts
- A credit union
- An online or non-bank lender such as Rocket Mortgage, Better or loanDepot
- An independent mortgage broker, who can price your loan with many wholesale lenders at once
- Your state housing finance agency’s approved lenders, if you are a first-time buyer
Compare Loan Estimates, not advertisements
Within three business days of applying, each lender must send you a standardized three-page Loan Estimate. Compare the interest rate, the APR, the origination charges in Section A, any points, and lender credits. Third-party costs such as appraisal and title insurance are broadly similar between lenders, so focus on what the lender itself controls. Then ask your preferred lender to match the best offer. Many will.
Should You Pay Discount Points to Lower Your Rate?
A discount point is prepaid interest. One point costs 1% of the loan amount and typically lowers your rate by around a quarter of a percentage point, though the exact trade varies by lender and by day. The opposite is a lender credit: cash toward closing costs in exchange for a higher rate.
Whether points are worth it comes down to a break-even calculation. As an illustration, on a $350,000 30-year loan, one point costs $3,500. If it lowers the rate from 6.50% to 6.25%, the principal-and-interest payment falls from about $2,212 to about $2,155, a saving of roughly $57 a month. Divide $3,500 by $57 and the break-even is about 61 months. Stay longer than five years without refinancing and the points pay off. Sell or refinance sooner and you lose money.
Also ask about temporary buydowns, such as a 2-1 buydown, often funded by sellers or builders. They reduce your rate for the first year or two only, so make sure you can afford the full payment afterwards.
When Should You Lock Your Rate?
A rate lock guarantees your quoted rate and points for a set period, usually 30, 45 or 60 days, while the loan is processed. Without a lock, your rate floats with the market until closing.
- Lock once you have a signed purchase contract and have chosen your lender. Trying to time the market is guesswork.
- Choose a lock period that comfortably covers your closing date. Longer locks cost slightly more, and extending an expired lock can be expensive.
- Ask whether a float-down option is available, which lets you take a lower rate if the market improves after you lock, and what it costs.
- Get the lock confirmation in writing, showing the rate, points, expiry date and loan program.
Fixed-Rate or Adjustable-Rate Mortgage: Which Is Cheaper?
A fixed-rate mortgage keeps the same rate and principal-and-interest payment for the life of the loan. The 30-year fixed is the US standard because it offers certainty and the lowest required payment. A 15-year fixed has a lower rate and saves a great deal of interest, but the monthly payment is much higher.
An adjustable-rate mortgage (ARM), such as a 5/6, 7/6 or 10/6 ARM, has a fixed rate for the first 5, 7 or 10 years and then adjusts every six months based on the SOFR index plus a margin. Caps limit how much the rate can rise at the first adjustment, at each later adjustment and over the life of the loan.
ARMs can start lower than fixed loans, but not always by much, so compare on the day. An ARM can make sense if you are confident you will sell or refinance before the first adjustment, for example if you are on a work assignment of a few years. If you plan to stay long term, or a payment jump at the cap would strain your budget, take the fixed rate.
How to Get a Low Mortgage Rate: Step by Step
- Check credit six months ahead and fix errors and utilization.
- Reduce DTI. Pay off small installment debts and avoid new ones. Most programs prefer a total DTI under about 43% to 45%.
- Build the down payment. Each LTV threshold crossed (95%, 90%, 85%, 80%) can improve pricing or reduce mortgage insurance. Explore first-time buyer programs and down payment assistance.
- Pick the right loan type. Compare conventional, FHA, VA and USDA. Our guide to buying your first home in the USA explains eligibility.
- Get preapproved, then request Loan Estimates from several lenders on the same day for the same loan type, term and points.
- Negotiate using the best competing estimate.
- Decide on points with a break-even calculation.
- Lock in writing and keep your finances stable until closing.

Look Beyond the Rate: Total Housing Cost
A low rate with high fees is not a bargain, which is why APR and the five-year cost comparison on page three of the Loan Estimate matter. Closing costs typically run 2% to 5% of the loan. Your monthly payment will also include property taxes, homeowners insurance and, with less than 20% down, mortgage insurance. Insurance premiums have risen sharply in several states, so get quotes early; our guide on how to lower your homeowners insurance premium can help.
Frequently Asked Questions
What credit score gets the lowest mortgage rate?
On conventional loans, the top pricing tier generally starts at a 780 FICO score, with very good pricing from 740. Government-backed loans are less score-sensitive, so a borrower with a 680 score may find FHA or VA pricing more attractive than conventional.
Can non-citizens get the same mortgage rates?
Permanent residents, and many work visa holders with a valid Social Security number, US credit history and documented income, can qualify for conventional loans on standard terms. FHA loans have been limited to citizens and permanent residents since 2025. ITIN and foreign national loans exist through specialist lenders but usually carry higher rates and larger down payments.
Is it worth refinancing later if rates fall?
Often, yes, if the rate drop is large enough to recover the closing costs of the new loan within the time you expect to stay.
Does getting preapproved lock my rate?
No. A preapproval confirms how much you can borrow, based on a credit check and documents. Your rate is only secured when you formally lock it with a lender, normally after your offer on a specific property has been accepted.
Bottom Line
Getting a mortgage with a low interest rate is mostly preparation and comparison. Raise your credit score into the highest tier you can reach, enlarge your down payment, choose the loan type that fits your profile, and collect Loan Estimates from several lenders inside the rate-shopping window. Then do the math on points, lock in writing and keep your finances steady until the keys are in your hand.
