Poor Building Data Is Creating a New Class of Stranded Property
For years, stranded assets in property were discussed in terms of location, obsolescence and changing demand. A secondary office in a weak market, a retail asset without footfall, a building whose floorplates no longer suit tenants. Those factors still matter. But a new dividing line is emerging: the ability to prove how a building performs. As lenders, insurers and buyers ask for auditable building-level evidence, owners with weak data rooms are finding that financing is slower, insurance is harder to place and valuations carry discounts that have little to do with the physical asset. The next class of stranded property may not be old or badly located. It may simply be unverifiable.
The gap between certificates and performance
Certifications and marketing materials were designed to signal intent and design quality. They are useful, but they are not a substitute for in-use evidence. A design certificate may show that a building was modelled to perform well; it does not show how it has actually operated, whether systems have been maintained, or whether energy use has drifted. Due diligence increasingly focuses on that gap.
Buyers want to know what the building consumes, what it costs to run, what safety issues have arisen and what capital has been deferred. Insurers want evidence of maintenance and risk controls. Lenders want to understand cash flow durability and compliance. When those records are missing or inconsistent, the building is not necessarily poor. It is simply harder to underwrite.
That distinction matters because pricing uncertainty is not neutral. It is translated into conditions, retentions, higher spreads or a lower headline price. A certificate on the wall does not answer the questions that a credit committee or an underwriter will ask.
Why data gaps become pricing problems
A transaction data room is not only a legal formality. It is the evidence base for the business plan. When energy data is incomplete, safety records are fragmented and capital expenditure history is undocumented, the buyer cannot distinguish between a well-run asset and one with hidden liabilities. The rational response is to price the risk or walk away.
Deals slow while consultants are commissioned to fill gaps. Lenders may require additional covenants or hold back funds. Insurers may attach conditions or exclude certain risks. Sellers may face re-trading after the initial agreement. None of this requires the building to be physically stranded. A well-located asset with strong tenant demand can become harder to finance if its records do not withstand scrutiny.
Lease obligations add another layer. Buyers need to understand not just headline rents but incentives, review structures, break options and service charge commitments. Capital expenditure history shows whether the building has been maintained or whether a backlog is being passed to the next owner. Safety records show whether statutory obligations have been met and whether remedial work is outstanding. These are not sustainability niceties. They are core underwriting inputs.
What an auditable asset record requires
The practical response is not a single certificate or a marketing brochure. It is a maintained asset record with clear ownership. That record should cover energy and water use, maintenance and safety inspections, capital expenditure, lease obligations and compliance documentation. It should be structured so that a third party can follow the audit trail, not simply read a summary.
Digital building passports, metering and structured data rooms offer a route to that outcome, but only if the data is complete and kept current. A dashboard that reports incomplete data can create more risk than no dashboard at all, because it implies a rigour that does not exist.
Asset managers should treat building data as core infrastructure. That means naming an owner for each dataset, defining how often it is reviewed and keeping evidence of how figures were produced. It also means preparing for diligence before a sale or refinancing is on the horizon. Data collected only at the point of transaction is expensive to assemble and easy to challenge. Data collected routinely becomes a management tool and a financing asset.
For lenders, the quality of that record can be as important as the headline valuation. For insurers, it can shape appetite and terms. For buyers, it can shorten the period between agreement and completion.
Recognition, verification and commercial pressure
The Global Property Awards provides a platform for recognising rigorous asset management, including work that improves operational transparency and the quality of building-level evidence. The property category can spotlight practices that others can learn from. But recognition is not verification. An award is not a substitute for an auditable record, and it does not remove the need for lenders, insurers and buyers to conduct their own checks.
The commercial pressure comes from capital markets, not from the awards circuit. Owners who can demonstrate what their buildings consume, how they are maintained and what obligations attach to them will find transactions easier to complete. Those who cannot will face more questions, more conditions and more discounts. That is the new stranded-asset test. It is less about whether a building is old or new, prime or secondary, and more about whether its performance can be proved.
Conclusion
The shift is gradual but structural. Data has moved from a reporting chore to a condition of finance and transaction. Owners do not need perfect data, but they need credible data. They need records that are complete enough to be audited, current enough to be trusted and structured enough to be used. In a market where capital is more selective, the ability to verify building performance is becoming part of the asset itself. The buildings that struggle will not always be the weakest physically. They will be the ones whose owners cannot show what they have.
