Fall 2026: The Great Yield Divergence — Why NNN Buyers Have the Upper Hand

Update · September 30, 2026
Two things have changed since this analysis was published on September 8:
What it means for buyers: the "Fed is easing" tailwind is off the table for now, so underwrite for higher-for-longer. Expect fixed-rate quotes above the 6.10–6.50% range in the leverage table, re-run positive-leverage math with live quotes, and stress-test at a 10-year of 5.25%+. The core case still holds for all-cash and low-leverage buyers: wider entry yields, thinner institutional competition and maturity-driven sellers. The Q2 cap rate figures (6.82% average, Boulder Group) remain the latest published survey.
The net lease market is sending a split signal this fall — and for disciplined buyers, it's the most attractive setup since 2023. The Federal Reserve has cut the federal funds rate to 3.50–3.75% , down 75 basis points from its spring level. Yet the 10-year Treasury has moved in the opposite direction, climbing to 4.69% . Meanwhile, NNN cap rates have expanded to 6.82% as of Q2 2026 (Boulder Group), marking the widest single-tenant net lease yields since Q1 2024.
This analysis draws on Q2 and early Q3 2026 transaction data across closed deals from Boulder Group, Marcus & Millichap, CBRE, and the latest REIT earnings guidance to map where the best risk-adjusted returns are hiding in plain sight.
The Divergence Explained
The Fed is easing. The bond market isn't cooperating. This disconnect — a steepening yield curve driven by sticky inflation at 3.4% CPI (July 2026), fiscal deficit concerns, and rising term premium — has created an unusual environment:
The result: a buyer's market with entry yields not seen in nearly three years, combined with a Fed that's clearly on a cutting trajectory. When short rates eventually pull long rates lower — and they will — today's 6.82% average cap rate on a quality NNN asset will look like a gift.

Cap rates have expanded across nearly every tenant category since spring. The widening is most pronounced in credit-sensitive segments, while investment-grade essential retail has held up better:
