The 10-year Treasury yield is a number many Texas landlords rarely check. This week it became the number that decides whether a rental deal works. The Federal Reserve’s H.15 release shows the 10-year at 5.28% on October 7, 2026, and Forbes reported that it traded above 5.35% that day, its highest level since 2002. Freddie Mac’s most recent survey that we could verify put the 30-year fixed mortgage at 7.28% (October 1), up from 7.03% the week before.
If you own, or are thinking about buying, a rental in Dallas–Fort Worth, that is not trivia. It changes three things at once: what the “safe” alternative pays, what your loan costs, and what your eventual buyer can afford. This article walks one realistic $300,000 DFW house through all three, with the arithmetic shown so you can swap in your own numbers. It builds on this week’s market report and on our earlier guide to analyzing a Texas rental property.
A note on method before the numbers. The house below is a hypothetical, built to be typical rather than to represent any specific property, and every input (rent, taxes, insurance) is an assumption you should replace with real quotes. The rates and yields are the ones published by the Federal Reserve and Freddie Mac, stated with their dates. This is general education, not financial or investment advice.
What actually moved: the rate environment on October 7–8, 2026
Here is the snapshot, with sources, so you know exactly what we are assuming:
- 10-year Treasury (constant maturity): 5.28% on October 7, 2026, per the Federal Reserve H.15 release. Forbes reported an intraday move above 5.35%, the highest since 2002, and a 30-year Treasury bond yield of 5.7%.
- 2-year Treasury: 4.77% on October 7.
- Effective federal funds rate: 3.88%, following the Fed’s September 16 decision to raise its target range by a quarter point to 3.75%–4%. For how a hike flows through to local housing, see our earlier piece on what a Fed rate hike could mean for DFW real estate.
- Bank prime rate: 7.00%.
- 30-year fixed mortgage (Freddie Mac PMMS): 7.28% on October 1, up from 7.03% on September 24 and 6.34% a year earlier. The 15-year averaged 6.60%.
One more number matters: the spread. The gap between the 30-year mortgage rate and the 10-year Treasury was roughly two percentage points on these figures (7.28% against a 10-year that was around 5.3% that week). That is arithmetic on two published numbers measured on slightly different days, not a forecast, but it explains the mechanics: when the 10-year moves, mortgage rates tend to follow within days.
We are deliberately not predicting where yields go from here. Forecasts on the 10-year range widely, and anyone who tells you with confidence that rates are about to fall, or about to keep rising, is guessing. The useful question is what your deal looks like if today’s rates are the rates you live with.
Test one: the risk-free comparison
The simplest test for any income property is whether it pays you more than a Treasury would for taking on the work and risk of a landlord. A 10-year Treasury at 5.28% asks nothing of you: no tenants, no roof, no hail claim, no vacancy. A rental must beat that, or you must have another reason, such as appreciation or leverage, to own it.
The income side of a $300,000 DFW house
Start with a house that rents for $2,300 a month. That is about 0.77% of the price, a plausible figure for a DFW single-family rental, and below the “1% rule” that beginners often assume, which we explain in the rental analysis guide. Our assumptions, all replaceable:
| Line | Annual amount | How we got it |
|---|---|---|
| Gross rent | $27,600 | $2,300 × 12 |
| Vacancy and turnover loss (6%) | −$1,656 | Assumption; vacant months and make-ready time |
| Rent actually collected | $25,944 | |
| Property taxes | −$6,600 | Illustrative 2.2% of price; check your county and any exemptions |
| Homeowners/landlord insurance | −$3,000 | Illustrative; Texas premiums vary widely, especially after hail |
| Property management (8% of collected) | −$2,076 | Assumption; self-managing removes this line and adds your time |
| Maintenance and capital reserve | −$2,400 | Assumption, about 0.8% of price |
| Net operating income (NOI) | $11,868 |
NOI divided by price gives the cap rate: $11,868 ÷ $300,000 = 3.96%.
That is about 1.3 percentage points below the 5.28% Treasury yield. Did we pick pessimistic numbers? Change them and see. Drop management to zero and NOI rises to about $13,944, a 4.6% cap rate, still below the Treasury. Cut taxes by $1,000 and you gain a third of a point. The conclusion survives reasonable tweaks: on a typical DFW single-family rental bought at market price, the income return alone does not beat the government bond.
That does not make the rental a bad idea. It makes clear what you are really buying: rent growth, appreciation, principal paydown, and tax treatment (talk to a CPA about depreciation and your situation). Those are real, but they are not guaranteed, and they should not be passed off as “cash flow.”
Test two: what leverage does to the same house
Now add a loan. Assume 20% down ($60,000) and a $240,000 30-year fixed loan, using 7.28% as the rate. Remember that this is the owner-occupied conforming survey rate, and investor loans commonly price higher, so this is a best case for the borrowing side.
- Monthly principal and interest: about $1,642
- Annual debt service: about $19,705
- NOI: $11,868
- Annual cash flow: NOI − debt service = about −$7,837
That is negative cash flow of roughly $650 a month before a single surprise repair. The same $240,000 at last year’s 6.34% would have cost about $17,902 a year, which still exceeds NOI, so this house did not cash-flow with a mortgage last year either. The rate jump made a thin deal thinner, and it did not create the problem. But it is an instructive picture of negative leverage: a loan that costs 7.28% against an asset that yields 3.96% subtracts from your return, not adds to it.
The DSCR view
Lenders who underwrite rentals on the property’s income look at the debt service coverage ratio, NOI divided by debt service:
$11,868 ÷ $19,705 = 0.60
Many DSCR programs look for roughly 1.0 to 1.25 or better, though the cutoff varies by lender and loan, so confirm with the actual lender. To see what rent that would take at these assumptions, work backward:
- DSCR of 1.0: NOI must equal $19,705, which requires rent of roughly $3,055 a month.
- DSCR of 1.25: NOI must reach about $24,632, which requires rent near $3,530 a month.
Those rents are 33% and 53% above our $2,300 assumption. This is why a conventionally priced single-family rental can fail the income test at these rates, and why the ones that pass tend to be bought at a meaningful discount to market, put more money down, or get priced with a rate buydown. If you want the full framework for these ratios, our rental analysis guide covers DSCR and cash-on-cash step by step.
Test three: the buyer you eventually sell to
Even if you never plan to hold, rates still reach your deal, because your exit is a buyer with a monthly payment budget. Using Freddie Mac’s survey rates and a 30-year term:
- A buyer comfortable with about $2,053 a month in principal and interest can borrow roughly $300,000 at 7.28%.
- The same payment supported roughly $330,000 at last year’s 6.34%.
That is about a 9% drop in the loan amount a buyer can carry for the same payment, before taxes and insurance, which in Texas are heavy. Sellers do not get to ignore that, and neither do flippers. For fix-and-flip investors the consequences stack:
- Your own financing costs go up. Hard-money and bridge pricing are set separately from mortgage rates, so get current quotes. Our guide to hard-money fix-and-flip financing walks through points, interest, and the true all-in cost.
- Your resale price ceiling comes down. Appraisals and buyer budgets are anchored to payments. If you underwrite your after-repair value (ARV) from comps closed when rates were lower, haircut it.
- Your hold gets longer. The TRERC’s July data showed days on market creeping up even before this month’s rate jump, per this week’s report. Model 90 days to sell, not 45, and price the carrying costs.
What still works: buying at the right number
The honest takeaway from all three tests is not “stop investing.” It is that the margin for paying too much has disappeared. At 7%+ rates, the deals that still work are the ones bought at a price that absorbs the bad news up front.
Keep the offer formula, and use the conservative end
The offer math we use for standard flips is ARV × 75–80% − repairs, and for clean, light-rehab properties, 85–92% of ARV. As an illustration, on a house with a $300,000 ARV and $40,000 in repairs, the standard formula gives a maximum offer of $185,000 to $200,000. In a market with higher carrying costs and a softer exit, the low end of that range is the sensible default, not the high end. A flat “70% rule” is not what we use and not what we recommend, because it ignores both the repair scope and the clean-rehab tier.
Think in “price versus yield”
For buy-and-hold, flip the earlier problem around: instead of asking what rent a $300,000 house needs, ask what price makes the rental work. If a house rents for $2,300 and you want a 6% cap rate to beat a 5.28% Treasury with some margin for risk, NOI must be $13,800 at a price of $230,000. At our expense assumptions that does not quite work either, because taxes and insurance scale with price and with the county rather than with rent, but the direction is clear: the price has to come down, and the cheapest place to find a lower price is a property that needs work, has a title or tenant complication, or belongs to a seller with a deadline.
Where the discounts come from
Distressed and as-is properties exist in every rate environment, and higher carrying costs and repair bills can push owners toward a quick sale. If you buy from them, the discipline is the same: verify the repair scope, price it, and use the formulas above. Our guide to how a cash offer is calculated shows the seller-side view of that same math, and our investor marketplace is where Diamond makes its deals available to buyers who want to see them.
A short checklist for this week
- Re-run every pipeline deal at the 7.28% survey rate or your lender’s actual quote, whichever is higher.
- Compute the cap rate and compare it to the 10-year. If you are below it, write down what you are betting on besides income.
- Check DSCR against your lender’s real minimum, not a rule of thumb from a podcast.
- Haircut your ARV if your comps closed before the rate climb.
- Hold the offer formula: ARV × 75–80% − repairs, with 85–92% of ARV only on clean light-rehab deals.
- Stress your hold period to 90 days or more, and price the interest, taxes, and insurance for that period.
- Watch Thursday’s Freddie Mac survey and the next TRERC release, because they will show whether the higher rate level is reaching closed sales.
