What a builder pays to borrow: spec construction runs 11.22%, and 447 basis points over prime

A speculative single-family construction loan carried an average effective interest rate of 11.22% in the first quarter of 2026, according to NAHB's quarterly Survey on Acquisition, Development and Construction Financing, released May 15. That is 447 basis points above the 6.75% bank prime rate, and it is the number a private builder actually pays to put up a house, as distinct from the 6.49% a buyer sees advertised on a 30-year mortgage. The two are different instruments for different borrowers, and this note is about the builder's side.

The survey tracks four loan types. In the first quarter the average effective rate, which folds in both the contract rate and the points charged up front, ran 9.36% on land acquisition, 10.15% on land development, 11.22% on speculative single-family construction, and 11.68% on pre-sold single-family construction (NAHB AD&C Financing Survey; Eye on Housing, May 15, 2026).

The direction split. Land acquisition and land development both eased over the quarter, acquisition down from 9.81% and development down from 10.28%. The two construction rates rose, spec up from 10.64% and pre-sold up from 11.01%. What makes that notable is that the contract rates on the construction loans actually fell over the quarter, from 7.47% to 7.31% on spec, while the effective rate climbed. The gap is points. Average initial points on spec construction loans jumped from 0.34% to 0.62%, and on pre-sold loans from 0.37% to 0.55%. On a loan that is drawn and paid off as fast as a single-family construction loan, roughly eight to nine months in the survey's model, a move in points shifts the effective rate more than a move in the contract rate does. Lenders lowered the sticker and raised the fee.

Measured against the 6.75% prime rate, the spread over prime widens with project risk: 261 basis points on land acquisition, 340 on land development, 447 on spec construction, and 493 on pre-sold construction. Land money is cheaper than vertical money, and it has been for the length of the series.

Two independent surveys measure whether builders can get a residential land or construction loan, one asking lenders and one asking builders, and in the first quarter they agreed. NAHB's own net easing index, drawn from builders, posted -2.7, where any negative reading means more respondents saw credit tighten than saw it ease. It is the closest that index has come to zero in four years, but it is still negative. The Federal Reserve's Senior Loan Officer survey, drawn from lenders, posted -4.9 on the comparable construction-and-land-development measure; the Fed treats anything between -5.0 and +5.0 as essentially unchanged. Both readings sit just inside tightening territory, and the first quarter marked the seventeenth consecutive quarter that both surveys have been negative at the same time (Eye on Housing, May 15, 2026; FRED SUBLPDRCSC).

How lenders tighten, when they do, is the part that reaches a small builder's term sheet. NAHB asks the builders who reported worse conditions which specific tactics their lenders used. Too few builders answered that question in the first quarter of 2026 for NAHB to report it, so the most recent published breakdown is the fourth quarter of 2025: 60% of those builders said lenders lowered the maximum loan-to-value or loan-to-cost ratio, and 47% each cited reduced loan amounts, required interest reserves, and required personal guarantees. The pattern there is structural rather than priced. When credit tightens on these loans, it shows up first as how much a lender will advance and what a borrower must personally guarantee, not as the rate.

One more figure worth a builder's attention: 35% of the builders NAHB surveyed financed at least some of their first-quarter homes with a construction-to-permanent, one-time-close loan made directly to the buyer, and among those builders an average of 51% of their homes were financed that way (Eye on Housing, May 15, 2026).

The public builders finance themselves differently, through bond desks and bank syndicates rather than the community and regional construction lenders that carry the private builder, so their capital news is context here rather than the story. Two items from June touch the Charlotte market. Berkshire Hathaway agreed on May 31 to acquire Taylor Morrison, which operates a Charlotte division, for $72.50 per share in cash, valuing the builder at roughly $8.5 billion including debt, a 24% premium to the prior close, with the deal expected to close in the second half of 2026 (Taylor Morrison investor release). It is the first major acquisition under Greg Abel, who took over as Berkshire's chief executive at the start of the year, and if it closes, Taylor Morrison goes private and delists. Separately, Lennar reported its May 31 quarter on June 11, repurchasing $447 million of stock during the quarter and redeeming $400 million of 5.25% senior notes shortly after the quarter closed (Lennar Q2 2026 release).

Total AD&C loans outstanding at FDIC-insured institutions, which include both residential and nonresidential construction and development lending, fell to $453.3 billion in the first quarter of 2026, down 0.6% from the fourth quarter and the ninth consecutive quarterly decline, even as single-family construction lending specifically edged up 0.8% over the same period (Eye on Housing, June 1, 2026). The aggregate pullback and the single-family uptick sitting side by side is itself a data point: the contraction in builder credit is concentrated outside single-family, even as the survey above shows single-family construction as the more expensive money.

The AD&C figures are a national quarterly survey average, based on 95 respondents surveyed in April 2026, and they lag; they are carried here as the first-quarter reading because that is the most recent NAHB has released. They are not Charlotte-specific, and no metro-level equivalent exists at this cadence; what a national benchmark gives a local builder is a way to know whether their own construction-loan terms are in line. Builder construction-loan rates and consumer mortgage rates track different drivers, bank capital and the fed funds target on one side, the 10-year Treasury and mortgage-backed-securities spreads on the other, and are not comparable numbers.

NAHB releases its second-quarter AD&C survey in mid-August 2026. The next Senior Loan Officer survey covering the second quarter is already out; the third-quarter reading follows in the autumn.
