Office Distress and Conversion: Where We Stand

Introduction

Office is where the commercial real estate downturn actually concentrated. While most property types stabilized through 2025, office delinquencies kept climbing, reaching an all-time high of 12.34% in January 2026 on Trepp's count of office loans inside CMBS pools. They have barely retreated since: Trepp's September 2026 reading was 12.16%, about a point above the 11.13% of a year earlier, and KBRA's broader office distress rate, which adds current loans already in special servicing, stood at 17.6%.

Against that backdrop, a genuine relief valve is scaling: office-to-residential conversions reached a record in 2025. Understanding where office stands means weighing both at once, a slow-burning distress problem and a conversion solution that works, but only on a fraction of the buildings that need it.

The headline maturity figures are large but not, by themselves, the crisis. Around $875 billion of commercial mortgages mature in 2026, down about 9% from the $957 billion due in 2025. The problem is concentration: about 17% of office loan balances come due in 2026, and office is the sector least able to refinance. More than $21.3 billion of CMBS office balances come due through the end of 2026, and over half of the roughly $100 billion in securitized mortgages maturing this year are unlikely to pay off on schedule.

The record came from a handful of large loans going bad at once. Trepp tied the January spike partly to two Manhattan loans turning delinquent: the $705 million CMBS loan on Worldwide Plaza, the 2-million-square-foot Midtown tower owned by SL Green and RXR, and the roughly $835 million loan on One New York Plaza. Single loans that size move the national rate on their own, which is why the series climbs in lumps. The same mechanism lifted the overall CMBS delinquency rate to 8.02% in September, its highest since late 2020, as large single-asset, single-borrower (SASB) loans that had missed their payoff dates at maturity turned nonperforming or moved to foreclosure.

The deterioration among already-matured loans is severe. Of office loans that matured before 2026 and still carry balances, 83.7% are delinquent and 92.7% are in special servicing, the workout process detailed in CMBS special servicing and workouts. The root cause is structural: tenancy never recovered from the permanent shift to hybrid work, so net operating income cannot support debt underwritten in a different era. How these situations resolve, from modifications to note sales to foreclosure, runs through office distress workouts and restructurings.

Maturity Default

A maturity default occurs when a borrower cannot repay or refinance a loan at its scheduled maturity date, even if it has kept current on monthly payments. It is the dominant form of office distress this cycle: the building still generates some cash, but not enough value to support a new loan, so the loan simply cannot be paid off when it comes due.

For three years, observers have predicted an office crash that has not quite arrived, and the reason is instructive. Lenders have overwhelmingly chosen to extend and modify rather than foreclose, because crystallizing a loss forces a writedown and floods the market with assets nobody wants to price. The result is a slow grind rather than a cliff.

The practical implication is that office distress is a multi-year story, not a single event. Assets are repricing toward levels where new buyers can make the math work, and the steady flow of workouts, note sales and recapitalizations that produces is itself the business: office has become one of the most active sources of special-situations mandates in real estate.

The single most important fact about office in 2026 is that "office" no longer behaves as one market. The national numbers have started to turn: Cushman & Wakefield's Q3 2026 office report put vacancy at 19.8%, down 25 basis points from a year earlier and the third straight quarter of year-over-year improvement, with sublease availability at its lowest since 2020. That average hides a widening split between trophy space that is thriving and commodity space that is still deteriorating. Cushman's own breakdown shows it: top-tier vacancy has fallen 215 basis points over two years, while Class B and C vacancy has kept rising.

The top of the market has, by most measures, already recovered. In 2025 trophy buildings captured about 55% of all leasing activity despite representing a small share of supply, Midtown Manhattan Class A rents sat about 6% above their pre-pandemic level, and Manhattan leasing reached 39.8 million square feet, the highest annual total since 2019. None of that looks like a sector in crisis.

Flight to quality

The migration of office tenants from Class B and C buildings into Class A and trophy space, often at similar or higher rents, in exchange for better amenities, location, and efficiency. It is the defining demand pattern of the post-pandemic office market, and it is why record-low vacancy at the top can coexist with record distress at the bottom.

The crisis sits at the bottom. Commodity Class B and C office, in the wrong locations with dated systems, is where the 12%-plus CMBS delinquency rate and the past-maturity backlog actually live. Tenants are not shrinking their office use so much as trading up: a company leaving a tired Class B tower for a smaller, better-amenitized Class A floor signs a healthy lease and empties a building that may never re-tenant.

For a banker, the bifurcation is the whole story: a single "office" number, whether vacancy, delinquency, or price, is almost useless, because the asset's tier determines whether it is a recovering investment or a workout.

Office debt is not held in one place, so the other current-state question is where the losses land. It splits mainly between the CMBS market, where delinquency is visible loan by loan, and bank balance sheets, where the exposure is larger but far less transparent. CMBS losses are crystallized through the special-servicing and workout process and disclosed to bondholders; bank losses are managed quietly through extensions and provisions.

The bank exposure is concentrated in the institutions least able to absorb it. Commercial real estate makes up roughly 44% of regional banks' total loans, against about 13% at the largest banks, and a meaningful slice of that is office, so analysts expect regional-bank loan-loss provisions to keep rising. Several lenders, including M&T, Regions, and Citizens, have been shrinking their office books, which realizes losses and removes a source of refinancing for the very borrowers facing maturity.

This is also why the resolution is gradual. As long as lenders can carry the loans, distress converts into a steady pipeline of workouts and discounted sales rather than a sudden flood, which is precisely the dynamic the distressed buyers are positioned to exploit.

Two forces are quietly tightening the market for good office even as the distressed inventory clears. The first is the return-to-office push, which moved from patchwork to mandate in 2025. JPMorgan ordered its roughly 317,000 employees back five days a week early in the year, Amazon's five-day mandate took effect in January 2025, and by mid-2025 about 54% of Fortune 100 employees were subject to five-day requirements, up from just 11% a year earlier. Companies bringing people back full-time need real space, and they overwhelmingly want it in the best buildings.

The second force is supply, and the turn is historic. In 2025, for the first time since at least 2000, more office space was removed from the US market than added: roughly 23.3 million square feet came out through conversions and demolitions. The shrinkage has continued. Cushman counts a 42.5 million-square-foot decline in total US office inventory over the six quarters to Q3 2026, while just 7.1 million square feet of new space was delivered in the first three quarters of 2026, about a fifth of the historical average and on pace for the lowest annual completions in more than 30 years.

For a banker, the implication is that the office recovery is not a rising tide; it is a sorting process, in which demand concentrates into a shrinking pool of viable buildings while the rest is repriced, repurposed, or razed.

The most discussed escape route is converting obsolete office into housing. The activity is real and accelerating: conversion starts grew from 1.6 million square feet in 2023 to 3.3 million in 2024, with an additional 8.8 million square feet proposed beyond 2025. Office-to-apartment conversions reached a record of roughly 70,700 units in 2025, up from just 23,100 in 2022, a 206% surge.

Adaptive Reuse

Adaptive reuse is the conversion of a building from its original purpose to a new one, most commonly office to residential, while retaining the core structure. It avoids demolition cost and can move faster than ground-up development, but only works where the existing floor plate, window lines, and mechanical systems suit the new use.

But the economics are unforgiving, and this is the part candidates often miss. Conversion costs typically run $250 to $650 per square foot depending on structural complexity, and the deal only pencils if the building is acquired at the right basis, generally below about $300 per square foot. Many office towers physically cannot convert at all: deep floor plates leave interior space with no windows, and plumbing and elevator cores were never designed for residential density. The detailed underwriting of which buildings work and at what price is the subject of office-to-residential conversion economics.

Conversion is concentrated in a few cities, and it is overwhelmingly policy-driven. New York City is the epicenter, with nearly 16,400 units in the conversion pipeline, up 97% year over year, catalyzed by the 467-m tax exemption enacted in 2024, which grants property tax relief in exchange for reserving 25% of units as income-restricted housing. The City of Yes zoning reforms and the 2025 lifting of the floor-area-ratio cap further widened eligibility. Washington, D.C. ranks second, with about 8,500 converted apartments under construction, up 30% year over year.

The marquee projects show the model at full scale, and one developer, RXR, sits behind most of them:

That a single developer can run several nine-figure conversions at once, with construction debt from Apollo and tax equity from JPMorgan, is the clearest sign the activity has graduated from pilot to playbook. The 55 Broad recapitalization shows capital now chasing stabilized, post-conversion residential assets as well as the distressed office that feeds them.

The geographic concentration is itself a tell. Conversion thrives where zoning is flexible, residential rents justify the cost, and incentives exist, while most of the country's distressed office sits in suburban and secondary markets with no conversion path at all. A vacant suburban office park with a low rent ceiling and no subsidy is a candidate for demolition or a deep-discount sale, which is why national conversion totals will stay modest despite the headlines.

The flip side of distress is opportunity, and 2025 was the year capital began to move on it in size. Distressed office investment volume topped $4.3 billion, the busiest year in a decade, with 168 properties trading, up roughly 31% on 2024, while a further $5.2 billion of office changed hands through foreclosure and bankruptcy auctions. Early 2026 ran ahead of that pace. After three years of buyers and sellers staring across a bid-ask gap too wide to cross, prices have reset far enough for deals to clear.

The discounts are extraordinary: some Chicago office has sold for under $30 per square foot, and downtown towers in Denver and Washington have changed hands at a small fraction of prior valuations. Early 2026 produced a run of headline resets:

Several of the buyers, Madison among them (it has also picked up 123 Mission Street, 600 Battery Street, and the Crocker Galleria), are deliberately assembling discounted portfolios rather than catching a single falling knife.

The buyer base is mostly private capital, about 55% of office transactions, and it splits into two camps. Conversion specialists pair a discounted purchase with a residential redevelopment plan, buying only the buildings whose floor plates and basis make the math work. Opportunistic investors bet that a well-located building bought cheaply enough will benefit when leasing and financing normalize, whether or not it ever converts. For a banker, this is the live deal flow: sourcing distressed sales, advising the lenders and special servicers disposing of assets, and recapitalizing the buyers.

Between a maturing loan the borrower cannot refinance and an outright foreclosure sits a layer of rescue capital that has become central to how office distress actually resolves. When a building's value has fallen below its debt but the sponsor still believes in the asset, fresh money can come in as preferred equity or a mezzanine piece, recapitalizing the deal so the senior loan can be partly paid down or extended without a forced sale. The same A/B note splits, discounted payoffs, and maturity extensions that define office workouts and restructurings are the tools that let a lender share the pain rather than seize the keys.

Rescue capital

Fresh preferred equity or mezzanine debt injected into an over-leveraged deal to recapitalize it, typically priced at low-to-mid-teens returns with significant control rights. It sits between the senior loan and the original sponsor's equity, plugging the gap that falling values opened, and it lets a maturing loan be paid down or extended without a forced sale.

The arithmetic is brutal but clarifying. A tower financed at a 5% cap rate in 2021 that now trades to a 9% or 10% cap has lost a large share of its value, so a loan that looked conservative at origination can sit far above the building's worth at maturity. Rescue capital is expensive and dilutive for the borrower but preserves the option to recover if the building re-leases, and it lets the lender defer a loss. Brokering that multi-party negotiation among senior lender, sponsor and new money is the special-situations advisory office distress generates in volume, and it has kept restructuring desks busy even when outright sales were scarce.

Slowly, and more slowly than looked likely a year ago. The clearing is three processes running in parallel: the trophy tier has effectively recovered, obsolete stock is leaving through conversion and demolition, and the large middle, neither prime nor hopeless, is repricing tower by tower as each discounted sale forces the next markdown.

What has changed is the rate backdrop. The Fed raised the federal funds target range to 3.75-4.00% on September 16, 2026, and the 10-year Treasury has traded around 5%, so the rate relief many sponsors were waiting on to refinance is no longer the base case. Higher for longer stretches the workout: more maturities miss payoff, loans already extended once need a second extension or a rescue recapitalization, and elevated cap rates hold values down. The backlog and bank-held losses will be worked off over years rather than quarters, keeping distressed sales and recapitalizations elevated well beyond 2026, with conditions improving at the top long before the aggregate does.

Putting the two halves together produces a sober conclusion. Conversion is genuinely scaling, but even a record 70,700 units is a rounding error against the hundreds of millions of square feet of struggling office stock nationally. The majority of distressed office will not convert, because it is in the wrong location, has the wrong physical structure, or cannot be bought cheaply enough to pencil. It will instead reprice to clearing levels, change hands at steep discounts, or in some cases be demolished, the bifurcation traced in the US office market's structural transition.

Where office sits in the broader recovery, still at the bottom and splitting sharply between recovering prime and recessionary commodity space, is mapped in cycle positioning across sectors. Office has, in 2026, found a floor in process rather than in price: the workouts, conversions, and repricings are all underway, but the sector still faces years of adjustment before the distressed inventory clears.
