The average 30-year fixed-rate mortgage climbed to 6.66% as of August 27, 2026, up slightly from 6.65% the previous week, according to Freddie Mac’s Primary Mortgage Market Survey released yesterday. A year ago at this time, the 30-year rate averaged 6.56%, meaning borrowers today are paying just 10 basis points more than they were in late summer 2025.
The 15-year fixed-rate mortgage averaged 5.98%, up from 5.95% last week, while a year ago the 15-year rate averaged 5.69%. The modest uptick reflects what Freddie Mac’s chief economist called a holding pattern: “Mortgage rates changed little this week averaging 6.66%,” said Sam Khater in the official release.
The numbers matter because even a one-basis-point change—0.01 percentage point—alters what buyers pay over the life of a loan. On a $400,000 mortgage, the difference between 6.65% and 6.66% is small on a monthly basis but compounds to hundreds of dollars over 30 years. More importantly, the rate environment shapes who can afford to buy and where the market is headed next.
The numbers
What this week’s rate survey shows
Freddie Mac’s data comes from thousands of real loan applications submitted by lenders nationwide.
The Primary Mortgage Market Survey results are based on mortgage rates collected from thousands of loan applications submitted to Freddie Mac through Loan Product Advisor from lenders across the country when a borrower applies for a mortgage. This methodology, updated in November 2022, replaced the older practice of surveying lenders directly. The current approach captures real-world rates at the moment borrowers lock in their loans.
Results are released weekly on Thursdays at 12 p.m. ET. The survey is focused on conventional, conforming, fully amortizing home purchase loans for borrowers who put 20% down and have excellent credit. Borrowers with smaller down payments, lower credit scores, or non-conforming loan amounts will see different rates—often higher.

Market context
Why rates are holding steady in the mid-6% range
The economy, inventory, and buyer behavior are all pushing in different directions.
Freddie Mac noted that the economy remains resilient, demonstrated by steady consumer spending and rising household incomes. When the economy runs hot, the Federal Reserve tends to keep interest rates elevated to prevent inflation from accelerating. That backdrop keeps mortgage rates from falling sharply.
At the same time, more homes are coming on the market and slower price growth in many areas are giving buyers better options and helping create a more balanced housing market, according to Khater’s statement. The National Association of REALTORS reported that 1.56 million existing homes were available for sale nationwide in June, an increase of 1.3% from the previous year, representing a 4.6-month supply of unsold homes. More inventory means buyers have more negotiating power and more time to shop.
The Fed cut its benchmark rate three times in late 2024 and three more times in 2025, but mortgage rates have not dropped in tandem. Rates ticked upward in March 2026 after the Trump administration launched Operation Epic Fury in Iran at the end of February, accompanied by a spike in gas prices and widespread uncertainty about the economy, and they briefly looked as if they’d drop after the U.S. and Iran announced a ceasefire in June 2026, but overall have remained elevated, ticking up slightly after the ceasefire appeared to fall apart in July. Geopolitical risk and inflation expectations have kept long-term Treasury yields—and mortgage rates—higher than many forecasters predicted at the start of the year.
Historical perspective
Between April 1971 and February 2026, 30-year fixed-rate mortgages averaged 7.70%. Over the past four decades, the 30-year fixed rate ranged from a 2021 low of 2.65% to a 1981 high above 18%. Today’s 6.66% rate is below the long-term average but well above the pandemic-era lows that many buyers still remember.
What it costs
How a 6.66% rate affects your monthly payment
A small rate change adds up over 30 years, but the bigger question is whether you can afford the payment today.
On a $300,000 mortgage at 6.66%, your monthly principal and interest payment would be approximately $1,920. At 6.65%, it would be $1,918—a $2 difference. Over 30 years, that’s roughly $720. The one-basis-point move this week is not material for most borrowers.
But the difference between today’s 6.66% and the 3% rates available in 2021 is enormous. That same $300,000 loan at 3% costs $1,265 per month—$655 less than at 6.66%. Over the life of the loan, the 6.66% borrower pays about $235,000 more in interest. That gap explains why so many homeowners with low-rate mortgages are reluctant to sell, and why so many would-be buyers are waiting on the sidelines.
Housing affordability remains strained, with the cost-to-income ratio for buying a home at 35%, surpassing historical benchmarks, and buying cheaper than renting in only around 2% of metropolitan statistical areas, according to J.P. Morgan Global Research. The National Association of Home Builders reported that a typical median-income family needed about 32% of its income to cover the mortgage payment on a median-priced home during the first quarter of 2026.
Still, the market is not frozen. Home sales rose 6.1% year-over-year, and prices are holding steady as buyers and sellers adapt to mortgage rates in the 6-7% range, according to Churchill Mortgage’s August market update. Buyers are learning to budget for higher rates, and sellers are adjusting their expectations. If you’re ready to buy and the numbers work at today’s rates, waiting for a dramatic drop may cost you more in the form of higher home prices or increased competition when rates do fall.

Your next move
What to do if you’re shopping for a mortgage now
Rates in the mid-6% range are the reality for 2026—but you have more control than you think.
First, shop around. Freddie Mac’s survey reflects national averages, but individual lenders quote different rates based on your credit score, down payment, loan type, and the property you’re buying. Comparing offers from at least three lenders can save you thousands of dollars over the life of the loan. Our financing guide walks through how to compare mortgage offers and what to watch for in the fine print.
Second, consider your down payment. Freddie Mac’s survey is based on borrowers who put 20% down and have excellent credit. If you’re putting down less, your rate will be higher—but you may still be able to buy sooner. Many first-time buyers use low-down-payment programs, including FHA loans (3.5% down), conventional loans with as little as 3% down, and state and local assistance programs that cover part or all of the down payment. Home buyer assistance programs reached a record 2,746 nationwide in Q2 2026, with growing grant funding and expanded eligibility helping more buyers overcome affordability and down payment challenges. Check our assistance programs page and zero-down options guide for details.
Third, look at the whole deal, not just the rate. Nearly half of sellers gave concessions to buyers in May, the highest May level in Redfin’s records, with concessions taking different forms including assistance with closing costs or a home warranty. Builders are offering incentives such as mortgage rate buydowns, and in the second quarter the average mortgage rate for a buyer purchasing a newly built home was 5.85%, compared with 6.47% for a buyer purchasing an existing home. A seller credit or builder buydown can reduce your effective rate or lower your upfront costs, making the deal work even when headline rates are high.
Finally, remember that mortgage rates are not locked in forever. If rates drop meaningfully in the next few years, you can refinance. Waiting to buy in hopes of lower rates means you’re also waiting through months or years of rising rents and potentially rising home prices. Run the numbers for your situation, and make the decision that works for your budget and your timeline. Our first-time buyer guide covers the full process from start to finish.
Expert forecasts for the rest of 2026
Fannie Mae’s June 2026 Housing Forecast projects that 30-year fixed mortgage rates will hover at 6.4% for the rest of 2026. The Mortgage Bankers Association forecasts rates of 6.5% in Q3 and Q4, while a June Reuters poll predicted rates will decrease to 6.4% in Q3 and 6.3% in Q4. In other words, most forecasters expect rates to stay in the mid-6% range through year-end, with only modest declines possible.
Quick answers
Mortgage rates at 6.66%: common questions
Is 6.66% a good mortgage rate?
It depends on context. The long-term average for 30-year fixed mortgages since 1971 is 7.70%, so 6.66% is below the historical norm. But it’s more than double the 3% rates available during the pandemic, which makes affordability much tighter for today’s buyers. Whether it’s “good” depends on your budget, your local market, and whether waiting for lower rates will cost you more in the form of higher home prices or rent payments.
Why didn’t mortgage rates drop when the Fed cut rates?
Mortgage rates don’t move in lockstep with the Federal Reserve’s benchmark rate. They track long-term Treasury yields, which are influenced by inflation expectations, economic growth, and global events. Rates ticked upward in March 2026 after geopolitical events in Iran, accompanied by a spike in gas prices and widespread uncertainty. Even with Fed cuts, inflation and geopolitical risk have kept long-term yields—and mortgage rates—elevated.
How much does a 0.01% rate change actually matter?
On a $300,000 loan, a one-basis-point change (from 6.65% to 6.66%) costs about $2 per month, or roughly $720 over 30 years. It’s not a deal-breaker. But a larger move—say, from 6.66% to 7.66%—would cost an additional $213 per month, or about $76,000 over the life of the loan. Small rate changes matter less than big ones, but every tenth of a percent adds up.
Should I wait for rates to drop before buying?
That depends on your situation. Most forecasters expect rates to stay in the mid-6% range through the end of 2026, with only modest declines possible. If rates do drop, more buyers will enter the market, which could drive up home prices and increase competition. There is no guaranteed timeline for a meaningful decrease, and lower rates could bring more buyers back into the market, creating additional competition. The right time to buy is when the numbers work for your budget and your life, not when rates hit an arbitrary target.
Can I get a lower rate than the Freddie Mac average?
Yes. Freddie Mac’s survey is based on borrowers who put 20% down and have excellent credit. If your credit score is higher, your down payment is larger, or you’re buying in a competitive market, you may qualify for a lower rate. Conversely, if your credit is weaker or your down payment is smaller, your rate will be higher. Always compare offers from multiple lenders—rates and fees vary significantly from one lender to the next.
Are there programs that can help me afford a home at today’s rates?
Yes. Home buyer assistance programs reached a record 2,746 nationwide in Q2 2026, with growing grant funding and expanded eligibility. Many programs offer down payment grants, closing cost assistance, or below-market interest rates. Check our assistance programs page for a full list, and visit your state’s housing finance agency website for local options.
