The Fed cut 175 basis points. Mortgage rates went up.

The most confident wrong sentence in real estate

"I want to wait until the Fed lowers rates."

The investor has done the homework. They know the market, they know the property, they have the capital ready. Then they read that the Fed is expected to cut, and they park.

The problem is that the Fed does not set mortgage rates. It never has. And a Fed cut is not a reliable signal that mortgage rates are about to fall. Often it has meant the opposite, and the current cycle is the clearest example on record.

That is not a contrarian take. It is the record. Here is the scoreboard since the current cutting cycle began.

The fed funds target upper bound was 5.50% the day before the September 2024 cut. It is 3.75% today. That is a drop of 1.75 percentage points, or 175 basis points, which is the unit the bond market counts in. Our glossary covers the rest of the vocabulary in this post. Over the same stretch the 10-year Treasury yield went from 3.70% to 4.72%, up 102 basis points. The Freddie Mac 30-year fixed average went from 6.20% to 6.69%, up 49 basis points. That survey figure is a weekly national average for owner-occupied conforming loans. Nobody can lock it. It is the cleanest public series for tracking direction, which is all it is used for here.

The Fed cut. Mortgage rates rose. Investors who parked in September 2024 to wait for cheaper money have now waited through six cuts and are looking at a higher number.

Does the Fed control mortgage rates? Two different prices

The federal funds rate is an overnight rate. It is what banks charge each other to borrow reserves for a single night. The FOMC sets a target range and steers toward it. That is the whole job. One night of borrowing, between banks.

That rate transmits fast and hard to anything priced directly off it. The prime rate has sat at the fed funds upper bound plus 3 points by convention for decades. Credit cards, home equity lines, auto loans, business credit lines, and most adjustable-rate debt reprice off prime. Cut the funds rate and a credit card APR moves inside a statement cycle.

A 30-year fixed mortgage is a different animal. It is a 30-year commitment at a locked price. Nobody funds that with overnight money. It gets funded by investors buying long-dated bonds, and those investors are pricing three decades of inflation, credit, and prepayment risk.

One clarification the table cannot hold. The Fed influences long-term yields, just not by setting them. It moves them through expectations, by changing what the market believes about inflation and the future path of policy. That is an indirect channel with a variable lag, and it is why a cut can be followed by long yields going either direction.

Short-term debt and long-term debt are priced by different people solving different problems. Everybody understands that a two-year CD and a 30-year bond are not the same instrument. The same logic applies here and almost nobody applies it.

How are mortgage rates determined, then

Two inputs. The 10-year Treasury yield, and the spread stacked on top of it.

The 10-year Treasury is the benchmark. The reason it is the 10-year rather than the 30-year is that most 30-year mortgages do not last 30 years. Borrowers sell, refinance, or pay off, historically around the seven to 10 year mark. The average life of the loan lines up with the 10-year note, so that is what lenders price against.

The spread covers everything a Treasury does not carry. A lender originates the loan, bundles it into a mortgage-backed security, and sells it to an investor who wants a yield above Treasuries for taking on prepayment risk, credit risk, and servicing cost. That premium is the spread, and it is the second half of the number on your rate sheet.

The Dallas Fed put arithmetic on this in May 2026. Researchers Matthew McCormick and Srini Ramaswamy found that "the mortgage rate exhibits a partial beta of less than 20 percent with respect to the fed funds rate, while exhibiting an 85 percent beta with respect to the 10-year rate."

In plain terms: move the 10-year Treasury by a full point and the mortgage rate moves about 85 cents of it. Move the fed funds rate by a full point while the 10-year holds still, and the mortgage rate moves less than 20 cents. That second figure is measured holding the 10-year fixed, which is the honest way to read it, because the Fed does reach mortgage rates. It reaches them through the 10-year, slowly and unreliably, rather than directly.

What happens to mortgage rates when the Fed cuts: September 2024

The clearest case study in recent memory is the one that started the current cycle.

On September 18, 2024, the FOMC cut by 50 basis points, the largest single cut since 2020. The move was covered as the beginning of relief for homebuyers. Here is what the 30-year fixed rate actually did, week by week, per Freddie Mac's Primary Mortgage Market Survey.

FOMC dates above are announcement dates. The Fed's own schedule lists these cuts by effective date, one day later.

Three cuts totaling 100 basis points. The 30-year rate rose 96 basis points from trough to peak across the same window. The 10-year Treasury finished 2024 at 4.58%, roughly 90 basis points above where it sat the day of the first cut.

The relief was real and it lasted about two weeks. Anyone who waited for the cut, watched the first two readings drop, and took another month to decide paid more than they would have the week before the Fed moved.

Why did mortgage rates go up after the Fed cut

Because the bond market trades tomorrow and the Fed confirms yesterday.

By the time an FOMC decision is announced, it has been priced for weeks. Futures markets publish live odds on every meeting. Traders position ahead of it. When a cut is 95% expected, the 10-year Treasury already reflects that cut, and so does every mortgage rate quoted off it. The announcement itself carries almost no new information about the thing everyone already knew.

What does carry new information is everything around the decision. The statement language. The dot plot. The chair's press conference. If the Fed delivers the expected cut but signals fewer cuts ahead than the market had penciled in, long yields rise on the news. The cut was priced. The hawkish guidance was not.

That is the September through December 2024 sequence exactly. The market got its cuts and simultaneously repriced its expectations for 2025 inflation and the future path of policy. Long yields went up. Mortgage rates followed the long yields, because that is what they do.

The short version, and the one worth carrying into a rate conversation: by the time the Fed acts, it is already built into the mortgage.

The same thing, in reverse: 2004 to 2006

If the argument were only about cuts, it would be a coincidence. It runs the other direction too, and the historical record there is even cleaner.

Starting in June 2004, the Fed raised the funds rate 17 consecutive times, 25 basis points each, from 1.00% to 5.25%. A 425 basis point increase over two years. By every popular assumption, mortgage rates should have gone through the roof.

The 30-year fixed rate was 6.25% the week before the first hike, in late June 2004. It peaked at 6.80% in July 2006, weeks after the last one. Net movement across 17 hikes and 425 basis points of tightening: 55 basis points.

The annual averages are more striking. Freddie Mac's 30-year average was 5.84% in 2004 and 5.87% in 2005. Three basis points of movement against roughly 325 basis points of hikes.

The 10-year Treasury over the identical span went from 4.70% to 5.22%, up 52 basis points. The mortgage rate moved 55. The two long instruments tracked each other almost perfectly while the overnight rate moved roughly eight times as far and dragged neither one with it.

The episode still has a nickname on trading floors: the conundrum. It was not much of one. Short rates and long rates are two different prices, and in 2005 they went their separate ways in public.

The spread nobody talks about

The 10-year Treasury explains most of the mortgage rate. It does not explain all of it. The rest is the spread, and the spread moves on its own.

Between 1990 and 2021 the spread between the 30-year mortgage rate and the 10-year Treasury averaged around 170 basis points, per the Mortgage Bankers Association. In 2023 it blew out past 300 basis points in some weeks. As of August 2026 it sits near 200, with the Boston Fed putting the April 2026 reading at approximately 200 basis points.

That range matters. On a 4.72% 10-year, the difference between a 170 basis point spread and a 300 basis point spread is 1.3 points on your mortgage rate, with no change in Treasury yields and no change in Fed policy.

Two things widen the spread. Interest rate volatility, because an investor buying a mortgage bond in a choppy market demands more compensation for uncertainty. And prepayment risk, because a mortgage investor can have their bond repaid early when rates fall, exactly when reinvesting is least attractive.

Which produces the uncomfortable second-order effect. A Fed that cuts into an unsettled inflation picture can raise volatility, widen the spread, and push mortgage rates up while Treasury yields hold flat. The cut and the higher rate are not a contradiction. One caused the other.

What a quarter point is actually worth

Set the macro aside. Here is the arithmetic an investor is actually deciding on, and it is the part that gets skipped.

Take a $150,000 single-family rental with 25% down. That is $37,500 in and a $112,500 loan at 75% LTV. Rent is $1,400. On a DSCR loan at 6.500% with the 10-year interest-only election, the payment is $609 a month. You can run your own numbers in our DSCR loan calculator. Then the operating costs, with every reserve funded rather than assumed away.

That is 7.7% cash-on-cash on the $37,500, with vacancy, maintenance, and capital expenditure all reserved. Plenty of pro formas reach a bigger headline by dropping the last two lines. A roof and a compressor do not care whether they were in the model.

Then it compounds, and this is what the year-one number hides. Rent rises. The payment does not.

Rent growth at 3% a year, taxes and insurance inflated at the same rate, all three reserves scaled with rent, nothing refinanced and nothing appreciating. Cash flow more than doubles by year 10 because the largest line in the model was frozen on the day of purchase. Cumulative cash flow across the first 10 years runs about $43,800, which returns 117% of the original $37,500 in cash before counting a dollar of equity.

Year 11 is the asterisk worth reading. The interest-only period ends and the payment steps up to $839 to amortize the balance across the remaining 20 years. Cash flow drops to roughly $338 and climbs from there, because by then rent has moved $538 while the payment moved $229. The fully amortizing election instead trades about $100 a month of year-one cash flow for roughly $1,257 of first-year principal, which is the same money in a different pocket.

Now the waiting question. Two versions, because the size of the improvement is the entire argument.

A quarter point takes a decade of the lower payment to earn back one year of waiting. A full point earns it back in under three.

So the answer turns on the size of the move and whether it shows up. A full point changes the arithmetic. A quarter point does not. And the record in the first half of this post is that the Fed has cut 175 basis points since September 2024 while the 30-year rate rose 49, which means the size and the timing of that move are not the Fed's to deliver.

One asymmetry is worth naming. A rate can be refinanced when the long end cooperates, subject to the prepayment penalty on the original loan, which on investor debt is commonly a three to five year step-down and is worth reading before signing. A year of ownership cannot be recovered. We covered the broader version of this in what waiting actually costs.

Illustrative example. Actual returns vary based on market conditions, property performance, and financing terms. Rate shown assumes a 750+ FICO borrower who owns a primary residence. Not a commitment to lend.

What waiting protects against

That math runs one direction. Here is the other, because a year of waiting is not only a cost.

Rates can go the wrong way. The 30-year survey average hit 7.79% in October 2023 and 7.04% in January 2025. An investor who bought at 6.500% and watched the market move to 8.5% still holds the better payment, and the refinance option simply sits unused.

Prices can fall. Buying the same property a year later at an 8% lower price beats any quarter point, and it changes the basis permanently rather than the payment temporarily.

The property can underperform. A four-month vacancy in year one costs $5,600 in gross rent against a vacancy reserve that funds about 18 days a year. An HVAC failure the inspection missed does something similar. Both are far larger than the rate question either way.

None of that is an argument for waiting or against it. It is the other half of the ledger, and a decision made on one half of a ledger is a guess.

What actually leads the number

If the Fed announcement is a lagging indicator, the leading ones are public and free.

The 10-year Treasury yield is the anchor, and it is quoted continuously. Lenders actually reprice off mortgage-backed securities rather than off the 10-year itself, which is why a rate sheet sometimes moves on a day Treasuries sit still. Inflation prints, CPI and PCE, move the 10-year because inflation is what long-bond investors are pricing. Employment reports move it for the same reason. Treasury issuance and auction demand move it, since supply sets price. And the MBS spread moves with rate volatility, which is why mortgage rates sometimes drift while Treasuries sit still.

Watch those and you are watching what mortgage lenders watch. Watch the FOMC calendar and you are watching a press conference about a decision the bond market made weeks ago.

What this means for rental property specifically

DSCR loans price off the same long-end machinery, plus a credit spread for investor-property risk. Our page on current DSCR loan rates tracks where that lands today. They are underwritten against the property's rental income rather than the borrower's personal income, which is why they scale across a portfolio in a way conventional financing does not.

That changes the question. A DSCR loan either covers debt service at today's terms or it does not. The rent-to-price ratio either works or it does not. Those are property questions with answers available today, and they do not resolve differently because of an FOMC vote.

The inputs that decide whether a rental performs over a 10-year hold are the ones an investor can actually verify: what the property costs relative to local rents, whether the market has real tenant demand, whether the state's landlord laws are workable, and what the roof and HVAC have left in them. Our framework for evaluating a rental property covers the specific checks, and the ROI walkthrough puts the full return together.

Rate is one line in that model. It is a real line. It is not the model.

How Lineage handles it

We underwrite properties against current financing terms, not projected ones. If a property only works at a rate that does not exist yet, it does not clear our process.

Financing is sized to the property's actual market rent through a DSCR loan, with the prepayment terms disclosed up front, so an investor knows what a later refinance would actually cost before signing rather than after. Insurance is quoted before the offer goes out, because a premium surprise moves a deal further than a quarter point does. Property management is referred to vetted operators with a track record in the market, and our guide on how to vet a property manager covers what to ask if you are sourcing one yourself.

Acquisition, lending, insurance, and management close as one coordinated transaction. You decide what to buy. We handle how it gets done.

The Fed will meet again. The headlines will run again. The 10-year Treasury will keep doing the actual work.
