Is now a good time for you to seek new financing for a rental property?
The 10-year Treasury yield increased by 51 basis points throughout September 2026, shifting the landscape for commercial real estate financing. This change directly affects rental property investors who rely on debt to fund their portfolios.
Why it matters
Higher Treasury yields often reduce the maximum loan amount that a property's rental income can support. Investors now face a environment where the cost and availability of financing have shifted compared to early September.
The 10-year Treasury yield climbed to 5.29% by September 30, 2026, up from 4.78% at the start of the month. This rise arrives following an August where DSCR loan volume grew 15% year-over-year, though specific impacts on individual debt-to-income ratios remain property-dependent.

The details
Rising Treasury yields typically increase the interest rates lenders require for commercial real estate loans, which directly lowers the debt coverage ratio for properties. As these borrowing costs rise, the amount of financing supported by a property's existing rental income decreases. Investors may find they have to contribute more equity to close deals that were previously supported by lower-rate debt.
Timeline
September 4, 2026: The 10-year Treasury yield began the period at 4.78%.
September 30, 2026: The 10-year Treasury yield concluded the month at 5.29%.
Money Landscape
The recent spike in the 10-year Treasury yield follows a standard pattern where rising benchmark rates tighten the amount of financing available to commercial borrowers. This shift follows an August where market volume remained high, highlighting the immediate tension between current rate environments and investor demand.
If you are currently evaluating a rental property purchase, re-run your debt coverage calculations using the higher current rate environment to ensure your loan amount remains viable. Consult with a qualified financial professional to determine how these financing shifts affect your specific portfolio strategy.
The takeaway
Rising Treasury yields have effectively lowered the borrowing power of rental property income for many investors. Review your existing loan commitments and speak with a qualified financial professional to assess if your current financing plans remain sustainable at these higher yield levels.
