Freddie Mac’s average 30-year fixed mortgage rate reached 7.28% for the week ending October 1, 2026, its highest level in three years. At the same time, the latest available existing-home sales report showed August sales down from July, and mortgage purchase applications fell in the week ending September 25. Those figures point to a cooling in buyer activity, but they cover different weeks and do not prove that higher rates alone caused the decline.
What the latest figures show
The mortgage-rate, application and sales measures are related indicators, not interchangeable data. The Freddie Mac figure is a weekly survey average; MBA tracks mortgage applications; NAR reports completed existing-home sales, with a lag.
| Measure | Latest figure | What it measures |
|---|---|---|
| 30-year fixed mortgage rate | 7.28% for the week ending October 1, 2026, up from 7.03% the prior week and 6.34% a year earlier | Freddie Mac’s Primary Mortgage Market Survey average for conventional, conforming, fully amortizing home-purchase loans; its borrower assumptions include excellent credit and 20% down. |
| 15-year fixed mortgage rate | 6.60% for the week ending October 1, 2026, versus 6.42% the prior week and 5.55% a year earlier | The corresponding Freddie Mac survey average for 15-year fixed loans. |
| Purchase mortgage applications | Down 4.0% week over week and 14.0% year over year for the week ending September 25, 2026 | MBA’s seasonally adjusted Purchase Index for the weekly change; the year-over-year comparison is unadjusted. Applications are not completed purchases. |
| Existing-home sales | 3.98 million annualized in August 2026, down 2.0% from July and 1.2% from August 2025 | NAR’s seasonally adjusted annual rate of completed existing-home sales. |
Freddie Mac and MBA reported slightly different fixed-rate readings because their surveys use different samples and methods. MBA’s September 30 release described its 30-year fixed rate as 7.3%, the highest since November 2023; that rounded MBA survey figure should not be treated as a competing exact quote to Freddie Mac’s 7.28%.
NAR had not yet released September existing-home sales when its calendar listed the next report for October 13, 2026. The latest completed-sales data in this comparison therefore describe August, not September or October.

Why higher rates can weigh on home sales
A mortgage rate changes the monthly principal-and-interest payment a buyer must qualify for at a given loan amount. When the rate rises, some buyers respond by lowering their budget, delaying a purchase, increasing their down payment, or dropping out of the market. A smaller pool of financed buyers can reduce demand and make it harder for sellers to find a match at their asking price.
The effect is not immediate or uniform. Existing-home sales count transactions that have closed, while applications are an earlier signal of people seeking financing. Rate movements can affect application activity before they appear in closed-sales statistics, and cash buyers are not directly exposed to mortgage rates in the same way.

NAR Chief Economist Lawrence Yun said, “Mortgage rates and home sales move in opposite directions, so it’s not surprising to see a mild dip in home buying activity due to high mortgage rates.” That describes a relationship, not proof that rates explain all of August’s decline. NAR also cited wages, job additions and available inventory as part of the broader market backdrop.
Affordability: what a rate change means for a buyer
NAR’s October 1 article illustrated the payment effect using its cited August median existing-home price of $429,100, a 10% down payment and a 7.28% rate: about $2,642 a month for principal and interest. This is an illustration, not an individual lender quote. It excludes property taxes, homeowners insurance, HOA dues, mortgage insurance and loan-specific fees, all of which can materially raise the total housing cost.

For an actual comparison, use a lender’s quoted interest rate and APR, not a national weekly average alone. The APR incorporates certain loan costs, while the rate determines interest used in the payment calculation. Compare offers for the same loan amount, term, down payment, points and lock period, and check whether the quote assumes a particular credit profile.
What the sales figures say about the broader market
August’s 3.98 million seasonally adjusted annual rate of existing-home sales was lower than July and a year earlier, but the longer trend was not uniformly downward: NAR reported existing-home sales up 1.6% year to date through the first eight months of 2026. One monthly decline should not be mistaken for a nationwide collapse or a forecast for every local market.

Inventory and price data also complicate the picture. NAR reported 1.62 million homes in inventory in August and a median existing-home price of $429,100, up 1.6% year over year. Yun put supply at 4.9 months and said the larger inventory gave buyers better opportunities to negotiate. Separately, NAR reported that Realtor.com found 20.8% of active listings had a price reduction in September, the highest September share since 2018. These measures may give some buyers more choice or negotiating room, even as higher borrowing costs strain affordability.

Adjustable-rate mortgages (ARMs) can start below fixed-rate offers, but the initial rate is not necessarily the rate for the full loan term. After the introductory period, the rate can adjust under the loan’s schedule and limits, changing the payment. The borrower should understand when adjustments begin, how often they can occur, the index and margin used, and the caps on increases.

In the MBA survey week ending September 25, ARMs made up 10.3% of mortgage applications, the highest share since October 2025. NAR’s reporting described ARM rates as around 80 basis points below fixed rates in that market snapshot. The spread is not a promise of savings for an individual borrower, and an ARM is not automatically cheaper over the time someone holds the loan. Compare its APR, fees, adjustment terms and possible future payment against a fixed-rate loan before deciding.
Quick Recap
How to compare a mortgage offer with the national averages
- Use the averages as context, not a quote. Freddie Mac’s 7.28% figure assumes a particular conventional conforming purchase-loan profile, including excellent credit and 20% down. Your lender’s offer may differ based on credit, down payment, loan type, points, property and location.
- Request comparable written estimates. Ask lenders for the same loan amount, term, down payment and rate-lock period, and compare both the interest rate and APR.
- Calculate the full monthly housing cost. Add estimated taxes, insurance, HOA charges and mortgage insurance where applicable to principal and interest.
- Test the budget against alternatives. Compare a lower purchase price, a larger down payment, paying points, or a different term. For an ARM, include a payment scenario after the initial fixed period and at potential adjustment limits.
- Recheck before locking. Weekly averages can move, and a published survey average does not reserve a rate for a borrower. Confirm the lender’s current terms, fees and expiration date.
What to watch next
- Freddie Mac’s weekly survey: whether average fixed rates continue rising or reverse direction.
- MBA’s application data: whether purchase demand continues to weaken or rebounds; these figures are a lead indicator, not closed sales.
- NAR’s monthly existing-home sales report: the September release was scheduled for October 13, 2026, and will show whether August’s dip continued.
- Local inventory, prices and reductions: national averages cannot show whether a specific neighborhood is gaining supply or seeing prices soften.
