Nashville mortgage rates eased again this week. As of August 20, 2026, the 30-year fixed averaged 6.65% and the 15-year fixed averaged 5.95%. Both figures come from the Freddie Mac Primary Mortgage Market Survey. The 30-year fell 2 basis points from 6.67%. The 15-year fell 1 basis point from 5.96%. That is a second consecutive weekly decline on both terms.
Here is the gap I want you to see. The survey and the rate sheet disagreed this week, and that gap is the story. The weekly average slipped. Daily lender pricing went the other way. The Mortgage News Daily 30-year index finished Thursday at 6.76% and Friday at 6.77%. That is up 6 basis points from 6.71% the previous Friday. The survey prices earlier in the week. It caught Wednesday’s rally on the Treasury buyback announcement. It missed the two days of oil-driven pressure that followed.
I publish this read every Friday for one reason. The weekly survey and the daily rate sheet do not move at the same speed. The gap between them is where borrowers get surprised. This week is the clearest example of that in months. For the running figures between these posts, the Nashville mortgage rate tracker carries the current week’s dashboard and payment math.
In this report
Market Summary
- Nashville 30-year fixed mortgage rate averaged 6.65%, down from 6.67% the prior week.
- Nashville 15-year fixed mortgage rate averaged 5.95%, down from 5.96% the prior week.
- Daily lender pricing ran higher than the survey. The MND 30-year index hit 6.77% on August 21, 2026, up from 6.71% the previous Friday.
- FHA 30-year mortgage rates were near 6.31% on daily lender pricing.
- The 10-year Treasury yield closed near 4.70%. It touched 4.75% Tuesday, the 2026 high, then reset lower on Wednesday’s buyback announcement.
- Mortgage spreads were near 1.95%, or 195 basis points, tighter by 2 basis points.
- Federal Reserve policy remained restrictive, with the target range held at 3.50% to 3.75%. The July meeting minutes, released August 19, read less hawkish than expected.
- Oil stayed elevated near $85 a barrel with the Iran conflict unresolved. That is the standing obstacle to lower borrowing costs.
Weekly survey figures come from the Freddie Mac PMMS. It prices conventional, conforming, fully amortizing purchase loans for borrowers putting 20% down with excellent credit. Nashville borrowers with different credit profiles, loan sizes, or property types will see quotes above or below these averages.
Mortgage Rate Dashboard
The mortgage rate dashboard shows a 6.65% 30-year fixed rate, a 5.95% 15-year fixed rate, and an FHA 30-year rate near 6.31%. The 10-year Treasury yield sits near 4.70%. The mortgage spread is near 1.95%, as of the week ending August 21, 2026.
Nashville Mortgage Rates This Week
Both fixed terms fell for a second straight week, but only barely. The 30-year came off 6.67% to 6.65%, a 2 basis point move. The 15-year gave back a single basis point to 5.95%. Sam Khater, Freddie Mac’s chief economist, framed the decline as modest relief for homebuyers. He repeated the point that shopping multiple lenders is worth more than the survey move itself. On that arithmetic he is right, and this week the daily market made the case for him.
The week in sequence
Oil ran the front of the week. Renewed Iranian threats and the seizure of a UAE tanker in the Strait of Hormuz pushed crude higher Monday. Treasury yields followed. By Tuesday morning the 10-year had briefly touched 4.75%, the highest yield of 2026. That level attracted enough buying to stabilize the market. Wednesday brought the announcement that reset the week. By Thursday and Friday the market was back to trading oil.
What the buyback announcement actually did
Treasury said it would at least double the maximum size of certain long-term buyback operations. That takes them from $2 billion to $4 billion, starting September 9. This is not quantitative easing. Treasury is not creating money to force rates down. It already repurchases older, harder-to-trade bonds to improve liquidity, funded through normal cash and borrowing operations. Investors still reacted hard because the change targets debt maturing in 10 to 30 years. The 30-year yield fell almost a tenth of a point while the 2-year moved slightly higher. That divergence is the tell. This was a liquidity adjustment, not broad stimulus.
Why the survey and the rate sheet disagree
Mortgage rates improved Wednesday too, but far less than the long end of the Treasury curve. Mortgage-backed bonds typically last only five to seven years as borrowers sell, refinance, or pay off. The Freddie Mac survey prices early in the week. It captured that improvement and none of the oil-driven pressure that followed. A Nashville borrower reading the headline sees a rate that fell. A Nashville borrower who called a lender Friday got a quote 12 basis points above the survey number. That 12 basis points is the number I would be planning against, not the headline. Year over year the comparison remains unfavorable on both terms. The 30-year sat at 6.58% a year ago, the 15-year at 5.69%.
Institutional Macro Snapshot
What Is Driving Mortgage Rates Right Now?
Three forces set the price of a Nashville mortgage this week, and not one of them was an inflation print. No CPI, PPI, or jobs report landed in this window. What moved the market was oil, a Treasury liquidity announcement, and a set of Fed minutes. The announcement made more noise than difference. The minutes read gentler than the market expected.
1. Oil is still the market mover
Iranian threats and the UAE tanker seizure in the Strait of Hormuz lifted crude and Treasury yields Monday. The 10-year touched 4.75% Tuesday morning, its 2026 high. Crude then finished the week higher than it was on Tuesday, near $85 a barrel with the conflict unresolved. Thursday made the relationship explicit. Oil jumped overnight and Treasury yields followed almost perfectly. Elevated corporate bond issuance from the hyperscalers added background pressure. Heavy corporate supply coincides with higher rates across the board. While oil stays where it is, inflation stays in the conversation, and Nashville borrowing costs stay elevated with it. That is the relationship I watch most closely right now.
2. The Treasury buyback announcement was a reset, not a rally
Wednesday’s news concerned Treasury’s long-term buyback operations. It will at least double their maximum size, from $2 billion to $4 billion, beginning September 9. It is worth being precise here, because the headlines were not. This is not quantitative easing. Treasury is not creating money to push rates down. It is repurchasing older, less liquid bonds to improve how the market functions. The purchases come out of normal cash and borrowing operations. The 30-year yield fell almost a tenth of a point on the news. The 2-year moved slightly higher. That is exactly what a targeted liquidity operation looks like, and exactly what broad stimulus does not. The honest test is the bond market itself. If yields stay compressed after the intervention, it worked. I will be reading the next two weeks of auctions as that test.
3. Low volatility is holding the spread, and the spread is holding your rate
The July 28 and 29 minutes were released Wednesday. They carried three dissents from members who favored raising rates. But the text said “some” participants were leaning that way rather than “many.” That single word did real work. It suggests the hawkish bloc is smaller than markets had priced. Add the liquidity the buybacks are meant to supply and you get the week’s quietest, most useful outcome. Volatility stayed contained. The spread between the 10-year Treasury and the 30-year mortgage did not widen. It tightened, from 197 basis points to 195. That is why the 10-year could push toward its 2026 high without Nashville mortgage rates going higher still.
The 10-Year Treasury and Mortgage Rate Spreads
The mortgage spread is the 30-year fixed rate minus the 10-year Treasury yield. This week it came to approximately 1.95%. That is a 6.65% Freddie Mac 30-year fixed rate against a 4.70% 10-year Treasury yield. A week earlier it was 1.97%, from a 6.67% rate and the same 4.70% yield.
The Treasury did nothing across the week and still made borrowers work for it. It ran from 4.68% to an intraday 4.75% Tuesday, then reset lower Wednesday. It finished roughly where it started. That is a lot of motion for zero net change, and the spread absorbed all of it. Every basis point of improvement in the survey rate came from spread compression. That has now been true three weeks running.
The level I am watching is 4.75% on the 10-year. That is essentially the 2026 high. So far it has acted as resistance, turning yields back each time they reach it. If that ceiling holds, the path from here is lower. If it breaks, 5.00% comes into view. At that point no amount of spread discipline keeps the 30-year in the 6.6% range.
A 195 basis point spread is still wide against the long-run historical norm of roughly 170 to 180 basis points. That gap is the excess cost sitting on top of every Nashville borrower’s rate. Closing it fully would take the 30-year toward 6.45% with no help at all from the bond market. That remains the clearest route to materially better pricing this year.
Payment Impact for Nashville Buyers
The locked comparison is a $500,000 purchase with 20% down and a $400,000 loan on a 30-year fixed. Principal and interest only, excluding taxes, insurance, HOA dues, and closing costs. At this week’s 6.65% the payment is $2,567.86. At last week’s 6.67% it was $2,573.16. The weekly improvement is $5.30 a month, or $1,908 across the full term.
Move the same math to the $1 million price point that dominates Brentwood, Franklin, and Green Hills. With 20% down, an $800,000 loan runs $5,135.72 at 6.65% against $5,146.31 at 6.67%. That is a $10.60 monthly improvement and $3,816 over the term. Against the 6.58% rate of a year ago, that same $800,000 borrower is paying $37.02 more each month today.
Here is the part the headline hides, and it is the figure I actually quote clients. Price that same $400,000 loan at Friday’s 6.77% daily index instead of the 6.65% survey average. The payment is $2,599.71, or $31.85 a month more. On the $800,000 loan the gap is $63.71. The survey number is the benchmark. The daily number is what you can actually lock, and this week they moved in opposite directions.
For investors the arithmetic is different because the debt service is underwritten against rental income rather than a household budget. A 2 basis point weekly move is noise in that calculation. What matters is where the rate sits when the loan funds. At these levels the debt-service coverage math still requires disciplined acquisition pricing on East Nashville homes and comparable inside-the-loop product.
Strategic Borrower Considerations in Today’s Market
Rates that move 1 to 2 basis points in a week do not change a purchase decision. They change the cost of waiting for one. And in a week where the survey and the rate sheet disagreed by 12 basis points, they change which number you should be planning against.
- Buyers should plan against the daily quote, not the survey headline. Ask your lender what today’s actual pricing is on your file and treat the Freddie Mac average as context. A quarter-point difference between lenders is worth more than a month of this kind of survey movement.
- Sellers should note what the headline hides. Rates fell, but the payment a buyer can qualify for did not improve this week. Pricing to the current payment band, rather than to spring comparable sales, is what produces offers inside 30 days.
- Investors are underwriting to debt service, not to sentiment. Three straight weeks of spread compression make a refinance window likelier than it was a month ago. That case rests on the 10-year respecting 4.75% rather than breaking through it.
- Move-up buyers carry the hardest math because they are trading a lower legacy rate for a larger balance. The question is not whether 6.65% is a good rate. It is whether the blended cost of the move clears the value of the house you actually want.
What I am telling clients this week
I have closed more than 550 short-term rental transactions in Middle Tennessee. In most of them the financing structure decided the deal before the price did. That is why DSCR and investor financing gets its own guide on this site rather than a paragraph.
In my experience the borrowers who get hurt in a week like this one read a headline on Friday and assume it is still true on Monday. The survey is a rear-view mirror. The lock desk is not.
Nashville Real Estate Market Outlook
This was a slow news week. Next week is not. Three things land. Core PCE, the Federal Reserve’s preferred inflation gauge, published by the Bureau of Economic Analysis. The Jackson Hole symposium, where Chair Kevin Warsh speaks for the first time in that role. And new Treasury auctions into yields already at the top of their 2026 range. Jackson Hole is where the Fed has historically made its most consequential policy signals. Any one of the three can move a Nashville rate lock more than everything that happened this week combined.
Why the Treasury auctions matter most
I am watching the auctions in particular. Strong demand supports the bond market and pulls yields down. Weak demand does the opposite. And it would land on top of oil pressure and heavy corporate issuance rather than instead of them. That is the scenario where the 4.75% ceiling gives way.
If the ceiling holds and the spread keeps compressing toward 180 basis points, the 30-year survey rate works into the mid 6.5% band with no help from policy. Two Nashville segments respond first. Entry-level product under $450,000 in Davidson County, and the $750,000 to $1.5 million move-up band across Williamson County, where a $20 to $30 monthly change compounds into real qualification headroom. If the ceiling breaks, the daily index leads the survey higher and Friday’s 6.77% quote becomes the floor rather than the spike.
For a longer view of how far this has traveled, last week’s rate update shows the 30-year at 6.67% against the same 4.70% Treasury. That frames how little the benchmark has actually moved, which is why I keep pointing clients at the spread rather than at the Treasury. Condo buyers working the FHA path should also check the FHA financing requirements for Nashville condos before assuming the 6.31% FHA note rate is available on a given building.
Nashville Mortgage Rates FAQ
What are Nashville mortgage rates today?
As of August 20, 2026, the 30-year fixed averaged 6.65% and the 15-year fixed averaged 5.95%. Both come from the Freddie Mac Primary Mortgage Market Survey. Daily lender pricing tracked by Mortgage News Daily put the 30-year index at 6.77% on August 21, 2026, and the FHA 30-year near 6.31%. Your actual quote will differ based on credit score, loan size, property type, occupancy, and lock period.
Did Nashville mortgage rates go up or down this week?
It depends which number you mean, and this week they disagreed. The Freddie Mac survey fell for a second straight week. The 30-year was down 2 basis points from 6.67% to 6.65%, the 15-year down 1 basis point from 5.96% to 5.95%. Daily lender pricing went the other way. The Mortgage News Daily 30-year index rose from 6.71% the previous Friday to 6.76% Thursday and 6.77% on Friday, August 21, 2026.
What is the mortgage spread and why does it matter in Nashville?
The mortgage spread is the 30-year fixed rate minus the 10-year Treasury yield. It came to 1.95%, or 195 basis points, as of August 20, 2026, against 1.97% a week earlier. It matters because it is the second lever on your rate. The 10-year Treasury finished the week flat near 4.70%, after touching 4.75% on Tuesday. The 30-year survey rate still fell, because the spread tightened by 2 basis points. Contained bond-market volatility is what keeps that spread from widening. A spread returning toward its historical 170 to 180 basis point range would lower Nashville mortgage costs without the Treasury moving at all.
What is the monthly payment on a $500,000 Nashville home right now?
Take a $400,000 loan on a 30-year fixed with 20% down. At the 6.65% survey rate as of August 20, 2026, principal and interest run $2,567.86 per month. That excludes property taxes, homeowners insurance, HOA dues, and any mortgage insurance. At last week’s 6.67% the same loan cost $2,573.16, so this week’s move saves $5.30 monthly. At the 6.77% daily index on August 21 it runs $2,599.71, or $31.85 more than the survey figure.
Are FHA rates lower than conventional rates in Nashville?
Yes, on the note rate. Mortgage News Daily showed the FHA 30-year near 6.31% on August 20, 2026, against a 6.76% conventional daily index the same day. That is a gap of roughly 45 basis points. FHA also carries an upfront mortgage insurance premium of 1.75% plus an annual premium. So the all-in comparison depends on your down payment and how long you hold the loan. Have your lender run it on your specific file.
Will Nashville mortgage rates fall before the end of 2026?
There is no FOMC meeting in August. The next policy decision comes September 16, 2026, with an updated Summary of Economic Projections. The nearer catalysts are Core PCE from the Bureau of Economic Analysis, the Jackson Hole symposium where Chair Kevin Warsh speaks for the first time in that role, and Treasury auctions into elevated yields. The 10-year has repeatedly turned back from 4.75%, its 2026 high. Whether that level holds matters more for Nashville pricing over the next month than the September meeting does. Nothing here is a forecast or a rate guarantee. Make any lock decision with a licensed mortgage professional on current pricing.
Sources and methodology
Rate data in this update reflects weekly averages from the Freddie Mac Primary Mortgage Market Survey (PMMS) as of August 20, 2026, released August 20, 2026. Daily lender pricing context comes from the Mortgage News Daily Mortgage Rate Index for August 20 and August 21, 2026. The 10-year Treasury figure of 4.70% is the August 20, 2026 close. It is corroborated by the Mortgage News Daily live quote of 4.695 on August 21, 2026, the same basis used in prior weekly updates. Official Treasury constant maturity closes from the Federal Reserve H.15 release of August 20, 2026 are 4.63% on August 13, 4.68% on August 14, 4.72% on August 17, 4.71% on August 18, and 4.65% on August 19. H.15 published on a given day carries data only through the prior business day. Spread analysis uses the 30-year PMMS rate minus the 10-year Treasury yield, both in percent, converted to basis points by multiplying by 100. Core CPI is the July 2026 reading published by the Bureau of Labor Statistics on August 12, 2026. It is carried forward because no CPI release fell in this week. Payment figures use the standard amortization formula for principal and interest only. The terms are a 30-year fixed with 20% down, excluding taxes, insurance, HOA dues, and closing costs. Year-over-year comparisons are taken from the Freddie Mac PMMS release itself.
