Nearly $150 billion of mortgages on U.S. office buildings are maturing by the end of 2024, and just over $300 billion of loans will mature by the end of 2026, according to a review of the CommercialEdge property databases as of October 2023.

The review of more than 80,000 office properties in the U.S. with $920 billion of mortgage debt found that 16.1% of loans by dollar volume will mature by the end of 2024, and 32.7% will mature by the end of 2026. Maturing loans are concentrated in the largest markets, led by Manhattan, Class A properties and in urban areas. Ten metros have more than $5 billion of office loans maturing through the end of 2024, and 10 have at least $10 billion of loans maturing by the end of 2026.

The volume of loan maturities is worrying, coming at a time when the combination of weaker demand, rising costs and lower property values are squeezing office owners while banks and investors are trying to reduce exposure to offices.

The advent of work-from-home has prompted companies to cut back on space requirements, especially in primary office markets with long commutes. The national office vacancy rate rose to 17.8% in September 2023, up 120 basis points year-over-year and up from 13.4% before the pandemic in January 2020, according to the October CommercialEdge office report.

As companies reduce requirements, the amount of sublease space is growing as well, to 2.5% of office inventory nationally. While average asking rents nationally have increased slightly since 2020, metros with high vacancy rates, such as Detroit, Houston and San Francisco, are seeing rent growth turn negative.

Office building tenants now have more options and leverage to negotiate for favorable terms, such as shorter lease terms and requiring landlords to finance renovations for amenities, including cafeterias, fitness centers, improved air circulation and outdoor break spaces. As tenant improvements and other costs increase, owners find it increasingly difficult to maintain net income. Consequently, office delinquency rates are rising and are likely to get worse as the growing number of underwater loans mature.

Over 15% of Office Loans Due by 2024

In the short term, through the end of 2024, we found just over 6,000 properties with $148.2 billion of mortgages that are scheduled to mature. That represents 16.1% of all volume of loans on office properties.

Total Office Loan Volume: October 2023

The metro with the most at stake is Manhattan, which is the largest market by virtue of having the most total office space and the highest price per square foot. We identified 1,159 office properties in Manhattan with loans, and 136 of those loans, totaling $19.8 billion, are maturing by the end of 2024, nearly double the next highest metro, Los Angeles, which has $10.3 billion of loans coming due over that period. Other metros with a large number of maturities by dollar volume include Chicago ($10.1 billion), Washington, D.C. ($8.6 billion), Houston ($8.1 billion) and Boston ($7.9 billion).

Office Loan Maturities Through 2024

Nine metros will see at least 20% of all office mortgages by volume maturing by the end of 2024, and, in tenth place, Nashville was close at 19.8%. Metros with the highest percentage of mortgage volume maturing in the short term include Houston (29.7%), Atlanta (28.8%), Connecticut (27.3%), Philadelphia (26.7%) and Chicago (26.4%).

One-Third of Office Loans Mature by 2026

When looking at a longer time frame, through the end of 2026, we found nearly 14,000 properties – accounting for 32.7% of all office property mortgage volume – with $300.9 billion of loans coming due. Ten metros have at least $10 billion of loans maturing, led by Manhattan, with $56.7 billion of loans maturing. Other metros with large maturity volumes include Los Angeles ($21.6 billion), Chicago ($17.9 billion), Washington D.C. ($16.2 billion) and Houston ($13.7 billion).

Office Loan Maturities Through 2026

Eight metros have at least 40% of total office mortgages coming due by 2026, and in 18 metros, at least 30% are set to mature. More than half of office loans by dollar value will mature by the end of 2026 in Atlanta (52.6%) and Houston (50.5%). Other metros with high percentages of maturities through 2026 include Chicago (46.8%), Denver (45.2%), Connecticut (44.7%) and Minneapolis (43.9%).

Maturing loans are concentrated in urban properties, which account for $176.9 billion, or 58.8%, of the loans maturing through 2026, while $123.8 billion are situated in suburban properties. Not surprisingly, primary markets are the leaders in both volume and percentage of urban office mortgages maturing: Manhattan ($56.7 billion, 32.5% of total mortgage volume), Los Angeles ($21.6 billion, 28.9%), Chicago ($17.9 billion, 32.2%) and Washington D.C. ($16.1 billion, 19.9%).

Houston ($13.7 billion, 50.5% of maturing mortgages) leads in the volume of suburban office properties with mortgages maturing by 2026, with other concentrations in San Jose ($10.4 billion, 25.1%) and Dallas $12.1 billion, 39.0%).

Office Loan Maturities by Urban & Suburban Regions

Another concentration is in higher quality properties, as just over two-thirds ($203.2 billion) of office loans maturing by 2026 are backed by assets rated “A+/A” by CommercialEdge, while $97.7 billion are rated “B” or “C.”

Manhattan, at $47.0 billion, leads in A+/A property mortgages maturing, followed by Los Angeles ($15.5 billion), Chicago ($12.6 billion) and Washington, D.C. ($11.9 billion). Metros with the most maturing mortgages on B/C offices are Manhattan ($9.7 billion), Houston ($7.6 billion), Los Angeles ($6.0 billion), Chicago ($5.3 billion) and Philadelphia ($5.3 billion).

Office Loan Maturities by Market & Improvement Rating Through 2026

The potential for default involves not just volume but the performance of the market and individual properties. Defaults are more likely to occur in markets that are overbuilt and/or have seen demand crushed as a result of the pandemic.

Metros with a combination of high vacancy rates and a large number of maturing loans by 2026 include Houston (24.9% vacancy rate as of October 2023 and 47.1% of loan volume maturing); San Francisco (24.2% vacancy rate with 30.1% of volume maturing); Austin (21.2% vacancy rate and 30.3% of volume maturing); Denver (20.7% vacancy rate and 41.3% of volume maturing); Atlanta (18.7% vacancy rate and 49.1% of volume maturing) and Chicago (17.9% vacancy rate and 42.4% of volume maturing).

One way rent declines play out is through the lease spread or the difference between the rate of expiring leases and new leases. A negative lease spread is a red flag because it signals weakness in demand and potential for declining rates going forward, while a positive spread indicates a more balanced supply-demand equation.

Office Vacancy & Lease Spread by Market: October 2023

As of October, lease spreads were negative in nearly one-third of major metros, with the largest negative gap found in metros including Pittsburgh (-10.5%), San Francisco (-5.4%), Chicago (-4.8%), Washington, D.C. (-3.3%) and Manhattan (-2.6%), our data shows. It is no coincidence that the largest negative spreads are happening in most of the biggest office markets in the country, which have had weak office attendance and lower demand and absorption post-COVID-19.

Metros with positive lease spreads – where new rents are rising – include Miami (9.0%), where the financial and business services sectors have grown in recent years, Austin (5.9%), Charlotte (5.6%) and Portland (5.5%).

To be sure, lease spreads can change from month to month and are not a perfect indicator. Positive lease spreads in any given period can mask potential longer-term problems. Austin, for example, has one of the most active development pipelines in the country, with nearly 6 million square feet under construction that will add 6.6% to current stock. While Austin remains a metro with rapid job growth, new office buildings are filling slowly as technology firms cut back growth.

Distress Rising – How Much?

The office sector is uniquely positioned among commercial property types for distress. Demand for space has dropped 10-20% since the onset of COVID-19, as workers have become accustomed to working from home, and most companies have embraced a hybrid workplace either out of convenience or necessity to retain workers.

While asking rents have remained flat – the average national asking rent as of September 2023 was $31.75, up 1.1% from the pre-pandemic level of $31.38 in January 2020, per the most recent CommercialEdge office report – net income is falling as expenses such as tenant improvements, maintenance and insurance are increasing rapidly.

Percentage of Loans Maturing Between 2023-2026, Vacancy Rate by Metro

The national vacancy rate has increased by 440 basis points since January 2020, with the biggest increases in core office markets like Manhattan and San Francisco. Going into the pandemic in January 2020, Manhattan’s vacancy rate was 7.9%, while San Francisco’s was 7.3%, our data showed. This October, Manhattan’s vacancy rate stood at 17.7%, up 200 basis points year-over-year, while San Francisco’s was 24.2%, up 450 basis points year.

Office property values are down sharply as capitalization rates increase. As of early November 2023, office REIT stocks were down 28% year-over-year and have produced a -10.8% average annual return over the previous five years.

Even though private measures such as the NCREIF Property Index (NPI) are much slower to react to changing prices, total returns for office properties in the NPI were -17.1% for the year ending 3Q 2023, while appreciation was -21.1%. Total returns for urban offices in the NPI were -20.6% during that period and -12.9% for suburban assets, and industry analysts expect private office property values to continue sinking.

Liquidity in the capital markets is a major headwind. Investor demand is weak, and lenders will only write office loans with low leverage and high coupons, terms that borrowers only accept as a last resort. CMBS investors are reluctant to buy bonds backed by offices.

Through three quarters in 2023, CMBS and collateralized loan obligation (CLO) issuers had securitized only $3.7 billion of office loans, down 75% from the year-earlier period, according to Commercial Mortgage Alert. As recently as 2021, offices served as collateral for $38.6 billion of loans securitized by CMBS and CLO issuers, per CMA.

Distress has already started to climb. As of October 2023, 5.8% of office CMBS loans were delinquent, up from 1.8% in October 2022 and 1.9% in December 2019, according to the CRE Finance Council and Trepp. Some $9.8 billion of CMBS loans on offices, or 8.3%, were in special servicing as of September 2023, per Trepp. Those negative numbers will increase as loans mature and properties face a funding gap – in other words, they qualify for less proceeds than existing debt in place because banks have grown more conservative while mortgage rates have shot up as Treasury and SOFR indexes rise.

How much office property distress will increase depends on the extent of interest rate increases and how long rates remain elevated. The worst-case scenario is if the job market weakens while property values continue to fall and interest rates rise from current levels. A more optimistic scenario would have the employment market remain strong while interest rates stop rising or even fall. In either scenario, office delinquencies are likely to jump, but the optimistic scenario would mitigate the pain as opposed to a larger crisis.
