U.S. 10-Year Treasury Yield Surpasses Single-Family Rental Returns for the First Time in Over 20 Years
nashnova research
In September 2026 the US 10-year Treasury yield hit 5.1%, topping the single-family rental cap rate of 4.8% for the first time in over two decades — risk-free government bonds now pay more, on paper, than owning and renting out a house.
What happened?
Reventure App CEO Nick Gerli reports the 10-year Treasury yield at 5.1% now exceeds the single-family rental cap rate — the ratio of rental income to property price — at 4.8%.
This means → an investor buying a rental property earns a lower nominal return than simply holding Treasuries.
The two lines have crossed for the first time since the early 2000s.
How did this crossover form?
Gerli cites a Reventure chart built on Zillow and Federal Reserve (FRED) data: from 2009 through the early 2020s, rental cap rates consistently sat above the 10-year yield.
The gap narrowed steadily between 2025 and 2026, finally inverting in September 2026.
In plain terms = the "extra return" that justified buying rental property over bonds has been shrinking for years — and it just went negative.
What does Gerli mean by "negative opportunity cost"?
Gerli labels the spread inversion a "negative opportunity cost."
This means → for the same dollar, putting it into a rental property now yields less on paper than the risk-free Treasury alternative.
In plain terms = rental investing used to mean "earn a bit more, take a bit more risk." Now it means "earn less *and* take more risk" — the math no longer works.
Has the investment-property market already shifted?
Gerli states that over the past four years, the number of Americans purchasing investment properties has fallen by 50%, and he believes this trend has materially affected home prices in some markets.
Note: the 50% figure is Gerli's own assessment and is not directly quantified in the accompanying chart.
This reflects a pattern where investors were already voting with their feet — exiting the rental-property market even before the formal inversion appeared.
Does this mean the US rental-investment thesis is permanently broken?
Whether the yield-versus-cap-rate inversion marks a structural shift in US property-investment logic remains to be confirmed by further market data.
This means → one signal alone is not conclusive, but it makes clear that the old case for buy-to-rent — justified purely by rental yield — no longer holds at current prices.
