Executive summary
A significant amount of commercial real estate debt is coming due in 2026 as borrowing costs remain elevated and tenant demand has shifted. In this environment, outdated valuation models can mask refinancing risk and neglect to give the full picture of how assets are likely to be viewed by lenders. Treating valuation modeling as a forward-looking discipline — incorporating ongoing scenario planning, financial due diligence and early risk indicator review — helps owners gain clearer insight into refinancing outcomes and make capital decisions as they prepare for potential refinancing.
Understand how your valuations will be tested in 2026
In residential real estate, a home mortgage is relatively straightforward: The rate is often fixed for decades, the payments are predictable, and over time, the balance steadily declines. Most homeowners never have to confronting their mortgage at maturity.
Commercial real estate works differently. Debt is structured to mature, often all at once. And, as many commercial real estate owners (CRE) owners are experiencing now, it may happen in the midst of market conditions that look vastly different from those that were in place when the loan was originally secured.
This year, a large volume of commercial mortgages are scheduled to reach maturity, prompting property owners to evaluate refinancing in a more selective, less predictable capital environment.
To do so effectively, owners need a clear, current view of their properties’ value to be able to evaluate how much debt an asset can actually support and how it may be viewed by lenders when refinancing is on the table. Yet many owners still rely on static valuation models built for a more stable environment. As assumptions around income, demand and financing evolve, those models can hide emerging pressure points, increasing the risk of surprises when debt comes due.
What is shaping valuations in 2026?
The commercial real estate landscape has shifted significantly in the last several years, particularly in the office sector. With the rise of remote or hybrid work models, fewer companies require the same amount of space. As a result, property owners face less tenant demand, which in many cases has compressed rental income.
That change is now colliding with a wave of maturing debt in a higher-rate capital environment. Many of these loans were originated when borrowing costs were as low as 4 to 5%, but today, even with modest rate cuts from the Federal Reserve — refinancing rates are often much higher.
As a result, even assets that are performing well today can face pressure when debt comes due. Buyers, appraisers and auditors are increasingly factoring that risk into how they assess property value.
“When an investor knows a loan is coming due, they’re going to price that refinancing risk into their bid,” said Keith Klemowits, Grant Thornton CFO Advisory Managing Director. “They may bid more cautiously, especially if there’s a chance the owner could become a forced seller.”
Appraisers and auditors are reviewing valuations through the same lens. “They’re asking whether an asset’s carrying value still holds up if refinancing proceeds are more limited,” Klemowits continued. “In some cases, that leads to short-term extensions. In others, it results in recapitalizations or distressed sales that reset pricing.”
Why is now the time to re-evaluate valuation modeling?
How does your team approach valuation modeling today? Is it treated as a static, point-in-time exercise or as a tool that reflects changing market conditions? Does it account for how assets are likely to be viewed by lenders in today’s capital environment?
Many valuation models used in commercial real estate were built for more predictable conditions. They were designed to support periodic reporting, not to evaluate how assets might perform as financing conditions, demand and lender expectations evolve.
“These models frequently rely on assumptions that were simply rolled forward — around rent growth, occupancy, refinancing terms and exit conditions — even when the market context that supported those assumptions has shifted,” Klemowits said. “When interest rates rise or tenant demand softens, those models often don’t reflect how assets would actually be evaluated under different conditions.”
A more effective valuation model reflects how assets are actually evaluated when debt comes due. That means incorporating current market inputs, testing sensitivity to changes in income and financing terms and understanding how a property’s value may shift as market conditions evolve.
When valuation modeling is reframed as a forward-looking tool, rather than a reporting exercise, it helps owners anticipate where pressure may build and where capital decisions may need to be refocused, instead of simply confirming past performance.

How can scenario planning change valuation decisions?
One way organizations are addressing today’s valuation challenges is by using interactive, scenario-based valuation models.
Rather than anchoring property value to a single outlook, scenario planning helps leaders understand how sensitive an asset is to change. In the office sector, for example, owners can test how value and refinancing capacity respond if leasing slows or borrowing costs rise. That visibility helps pinpoint where assumptions begin to break down and which variables are driving them.
Scenario planning also helps leaders reframe conversations around risk tolerance, investment concentration and timing — especially for large or long-term projects.
“Teams aren’t always dealing with a broken model. More often, they’re not asking the right questions early enough — particularly around where investments are concentrated, or which risks haven’t been revisited in light of current market conditions,” Klemowits said. “That requires an awareness of how similar companies are responding to the environment and where blind spots tend to emerge.”
Case study spotlight
Grant Thornton’s real estate and valuation modeling team recently worked with a large development client planning a large mixed-use project that included hotels, entertainment, retail and dining. Given market and demand uncertainty, the client asked for an interactive model that could test a wide range of scenarios.
Working closely with the development team, Grant Thornton helped evaluate how changes in demand assumptions, financing terms and development timing could affect both near- and long-term outcomes. By adjusting variables in real time, the client gained a clearer view of where returns were most sensitive and which decisions would have the greatest impact before capital was committed.
How does financial due diligence impact valuation?
Companies also need to rethink financial due diligence practices so that valuation assumptions are tested against updated market and lender expectations. As refinancing outcomes become harder to predict, due diligence plays a bigger role in understanding how an asset may be viewed by lenders, investors and auditors when capital decisions are on the line.
“The metrics a company used to secure financing five or 10 years ago no longer apply. Rent rolls, tenant demand and property use have all evolved,” Klemowits said. “Financial due diligence helps put the pieces together so owners can understand what has changed, when it changed and what that means for value.”
Effective financial due diligence typically focuses on several core areas that influence valuation and refinancing capacity:
- Income durability: Reviewing rent rolls, lease expirations, renewal assumptions and tenant credit to assess the stability of cash flows as debt matures.
- Expense and margin pressure: Evaluating operating costs, capital expenditures and net operating income trends to determine whether historical performance still rings true.
- Debt capacity and coverage: Analyzing debt service coverage and leverage under current market terms, rather than prior financing assumptions.
- Sensitivity to change: Assessing how valuation shifts if leasing weakens, downtime between tenants increases or borrowing costs rise further.
“Financial due diligence isn’t just a checklist to satisfy — it directly informs investment decisions and negotiations,” Klemowits said. “If a review shows leasing outlooks are weakening, an owner may decide to sell sooner rather than later or invest in re-leasing efforts sooner to stabilize the property.”
Are leaders spotting risk indicators early enough?
In commercial real estate, valuation pressure rarely emerges all at once. It builds gradually through changes in income, expenses, leasing behavior and debt coverage. By monitoring these indicators proactively, owners and investors can surface potential issues before they become critical and reflect those shifts in valuation accordingly.
Early indicators of capital risk
Property owners regularly review trends in:
- A property’s income and expenses
- Lease maturity profile
- Debt coverage metrics
- Tenant credit health
- Broader market conditions
- Interest rate exposure
“It’s not that the metrics themselves are new,” Klemowits said. “It’s about paying closer attention to them. If tenants who always paid on time start paying a few days late, and that pattern spreads, that’s a signal worth investigating.”
Maintaining that level of visibility typically requires more than periodic reports. Owners benefit from integrated valuation models that combine leasing, operating and debt data and are refreshed as conditions change. These models should allow assumptions to be revisited regularly, stress-tested through scenarios and highlight emerging risk.
For many organizations, maintaining that level of integration and review cadence is challenging. Lean teams are often focused on operations and new initiatives, leaving limited capacity for continuous monitoring. External support can help maintain consistent valuation inputs, refresh assumptions regularly and provide an independent perspective grounded in current lender and market expectations without pulling internal teams away from core priorities.
What should commercial real estate owners do now?
As debt comes due in a tighter capital environment, CRE leaders should approach valuation with greater rigor and attention. Owners and developers who embed valuation into ongoing portfolio oversight will be better positioned to protect asset value and navigate the maturity wall with fewer surprises.
- Treat valuation as an ongoing process, not a periodic report. Update assumptions regularly so asset values reflect current leasing conditions, financing terms and lender expectations — not the environment from when the deal was originally underwritten.
- Pressure-test valuation assumptions before capital decisions are forced. Use scenario planning to understand how value and refinancing capacity shift if income softens, borrowing costs rise or timelines extend.
- Use financial due diligence to validate what’s changed. Reassess rent rolls, tenant demand, operating costs and debt coverage to determine whether historical metrics still support today’s valuation.
- Build early-warning indicators into portfolio reviews. Monitor leasing trends, tenant behavior and debt metrics more frequently so emerging pressure is reflected in valuation before options narrow.
- Address refinancing risk proactively. If valuation and due diligence suggest refinancing may be constrained, get ahead of that risk — whether that means adjusting leverage, bringing in capital partners or adjusting the timing of a sale.
