In the evolving post-pandemic office landscape, a significant and nuanced bifurcation has emerged, reshaping how investors and lenders approach office assets. While GlobeSt.com has long chronicled the divide between the strong performance of Class A and trophy office buildings and the struggles of Class B and C properties, new data analyzed by Trepp reveals an equally critical split rooted not just in asset quality, but also in geography, loan structure and borrower profile.
Trepp’s analysis of $165 billion in securitized office debt reveals that 83% of this debt—more than $137 billion—is concentrated in urban settings, resulting in a five-to-one ratio favoring gateway metro areas. This geographical concentration reflects a historical legacy where major corporate presences were centralized in urban cores.
However, according to Trepp’s Thomas Taylor, recent credit metrics and loan origination data from 2025 highlight dynamic shifts, with growing activity in high-quality suburban office assets alongside select urban buildings that demonstrate resilient cash flows. Notably, suburban office loans have been underwritten more conservatively in key respects compared to their urban counterparts.
Examining 2025 originations, suburban office loans demonstrated an average debt service coverage ratio of 2.47x, significantly exceeding not only the typical minimum benchmark of 1.25x but also the 2.01x average DSCR seen in urban office loans. This indicates lenders are requiring—and receiving—stronger net operating incomes relative to debt obligations in suburban office transactions, signaling a conservative underwriting stance.
Similarly, loan-to-value ratios for suburban offices averaged 53.01% in 2025, markedly lower than the nearly 67% LTV measured in 2015 and even the 54.29% recorded in 2023. In contrast, urban office LTVs averaged 55.99% in 2025, up from 48.09% in 2023, although still below the levels seen a decade ago.
Capitalization rates further underscore the distinction. Suburban offices carry an estimated average cap rate of 8.97%, compared to 7.16% for urban offices, implying that equity investors may realize higher yield premiums in suburban markets and that risk premiums are priced more aggressively outside dense urban cores.
Together, these metrics reveal a landscape where suburban office loans are entering the market with stronger structural fundamentals, offering greater downside protection through conservative underwriting. Urban offices maintain a valuation premium but face challenges from higher leverage levels and tighter underwriting in some cases, affecting their refinancing outlook.
Trepp cautions that with approximately $40 billion in urban office CMBS debt maturing by the end of 2026—split between $9.2 billion in 2025 and $10.5 billion in 2026 compared to $6.2 billion in suburban maturities—bondholders should closely monitor urban core exposure, particularly where legacy loans assumed low cap rates and elevated LTVs.
Lenders may increasingly favor suburban office assets, leveraging their higher DSCRs and lower leverage to manage risk more effectively, while equity investors might find compelling value in suburban properties that offer strengthening lease metrics and superior cash-on-cash returns relative to urban options.
