THE GOVERNMENT LEASE SAID TEN YEARS. FIVE WERE FIRM.

THE CASE

A federal office can report ten years to lease expiration while giving the government an exit right after year five. At the next refinancing, sale, or appraisal, the protected cash flow ends on the firm-term date. The remaining five years behave like an option held by the tenant.

The distinction is written into the contract and routinely flattened inside a rent roll.

GSA defines the firm term as the portion of a lease insulated from termination rights. The non-firm term begins when those rights become exercisable. Current awards still use structures such as “10 years, 5 years firm.” After the firm term, the government can often terminate all or part of the premises with a specified notice period.

Government credit answers whether an obligated rent payment will be made. Firm term answers how long the payment remains obligated. Reuse answers what happens after it stops. A durable underwriting view requires all three.

Mendria calls the controlling metric Firm-Term Coverage: the amount of non-cancellable lease duration that protects the investor's hold and the lender's loan term, adjusted for partial termination rights, termination fees, agency substitution, and the asset's cost of recovery. The investing edge sits in the gap between stated lease life and protected capital life.

WHY THIS CASE MATTERS

The earlier Mendria cases located price signals outside the standard property file. Note 04 traced insurance terms into financeable NOI. Note 06 traced grid deliverability into data-center value. Note 07 traced environmental evidence into lender and buyer conditions. Note 08 traced a biotech tenant's operating strategy into Economic WALE.

This case is more severe because the decisive signal can already sit inside the lease abstract.

A conventional model may capture the stated expiration, passing rent, government agency, occupancy, renewal options, and a single WALE. It can still miss:

• the first date on which rent can stop without tenant default;
• whether the government can terminate the entire premises or a portion;
• the required notice period;
• whether a termination fee converts cancellable term into protected economics;
• which tenant improvements and security costs have finished amortizing;
• whether another federal agency can occupy the space;
• whether the agency's internal Occupancy Agreement aligns with the landlord lease;
• whether the debt extends past the protected term;
• and what the building costs to release, decommission, divide, or convert.

That omission once looked academic. The 2025 federal lease-reduction campaign activated termination rights across hundreds of leases. A Yale working paper reconstructed the episode from GSA inventory, termination announcements, Trepp, and CMBS data. In its historical series, annual cancellation rates for soft-term leases had generally run around 3% to 4%; the rate reached 12% in March 2025. The authors modeled an average 5.5% property-value jump loss at early-termination notice in their Washington, D.C. simulation.

Those figures are research estimates, distinct from closed-sale evidence. They establish the correct object to underwrite: a contractual option can remain lightly exercised for years, then become economically salient across an entire asset cohort.

The market learned that “rarely exercised” and “unexercisable” occupy different columns.

THE GOVERNMENT OWNS A PUT OPTION ON THE SPACE

The cleanest way to read a 10-year / 5-year-firm lease is as two consecutive instruments:

• Five years of protected rent. The government lacks the contractual termination right during the firm term, subject to the actual lease language and lessor performance.
• Five years of tenant optionality. The government may continue paying and occupying, reduce part of the footprint where the lease permits, or terminate after the notice requirement.

The second instrument belongs to the government. The landlord carries the corresponding vacancy, capital, timing, and residual-value exposure.

GSA's Automated Advanced Acquisition Program illustrates the mechanics precisely. Its published alternatives include 17 years / 15 firm, 15 years / 13 firm, and 10 years / 8 firm, each followed by government termination rights in whole or in part with at least 120 days' written notice. Other GSA procurements use 10 years / 5 firm. A June 2026 lease award in Mount Laurel, New Jersey covered 26,107 rentable square feet for ten years, five firm, plus a five-year renewal option. A June 2026 award in Ponce, Puerto Rico also used ten years, five firm.

The stated term therefore mixes contracted duration and optional duration. Summing both into one WALE treats a tenant-owned right as landlord-owned cash flow.

The error becomes more consequential when tenant improvements sit inside the lease economics. GSA's AAAP guidance says the lessor funds tenant improvements upfront and the government repays them, with interest, over the first eight years under that program. Building Specific Amortized Capital can include bollards, gates, blast-resistant film, and guard booths. A lease with a short firm term, a longer amortization schedule, or asset-specific security work requires exact contract review. Timing determines whether remaining improvement economics are paid, stranded, negotiated, or embedded in the soft tail.

THE LANDLORD LEASE AND THE AGENCY OCCUPANCY AGREEMENT

There are two contractual layers in many GSA occupancies:

• the lease between GSA and the private owner; and
• the Occupancy Agreement between GSA and the tenant agency using the space.

These documents allocate different risks.

GSA explained the distinction in 2023. Historically, some tenant agencies could cancel an Occupancy Agreement on 120 days' notice while the underlying private lease remained in force. GSA carried the vacancy and searched for another federal occupant. As agency space demand weakened, that internal backfill assumption became less reliable.

GSA then made new and continuing Occupancy Agreements for leased space non-cancellable through the initial underlying lease term, commonly the firm term; option years remained outside that protection. Existing agreements executed before April 18, 2023 remained under their original terms under the announced guidance.

For an owner, an agency releasing space to GSA and GSA terminating the landlord lease are different events. The first can change use, visibility, and renewal probability while rent continues. The second ends the rent obligation after the contractual notice period. Mendria keeps the events separate and connects them through agency substitution rights, GSA's internal demand, and the exact lease language.

That distinction creates a valuable early signal. A tenant agency can begin consolidation, reduce local staff, migrate functions, or plan alternative space while the owner continues receiving rent. GSA can explore a replacement federal occupant. The legal cash flow remains protected through firm term. The forward probability of the soft tail moves much earlier.

THE 2026 PUBLIC-PORTFOLIO PROOF

Easterly Government Properties supplies an unusually transparent public example. Its August 2026 presentation reports 106 operating properties, 10.7 million leased square feet, and $394.0 million of annualized lease income as of June 30, 2026. The portfolio's weighted average remaining lease term was:

The 1.2-year difference equals 13% of the stated 9.2-year average. Its meaning varies by asset because soft term is concentrated in specific leases.

Easterly's lease-expiration schedule covers 148 leases. The footnote reports eight U.S. government tenants occupying 4.0% of leased square feet and producing 4.3% of annualized lease income under provisions that currently permit termination before stated expiration. Applying 4.3% to the disclosed $394.0 million of annualized lease income yields approximately $16.9 million of current annual income subject to exercisable termination rights.

This is high-quality disclosure. It reveals the gap instead of forcing investors to estimate it.

The same presentation reports a 4.0-year weighted average debt maturity. At portfolio level, the 8.0-year firm-term WALT exceeds that debt horizon. Asset-level financing can produce a different result. One mortgage may mature after its tenant enters soft term while another remains protected for years. Portfolio averages can offset the exact collision a property lender will underwrite.

Easterly also explains why it expects many tenants to remain: build-to-suit features, mission-critical functions, operational use, and relatively young renovation-to-suit vintages. Those facts belong in the probability model. They cannot erase the termination right. They change the likelihood of exercise and the recovery path.

The sophisticated conclusion carries two variables at once:

Specialization compresses exit probability and amplifies exit severity.

A secure laboratory, courthouse, field office, or command facility can be costly for the government to replace. That supports retention. The same security, circulation, laboratory infrastructure, remote location, or single-purpose layout can make private-sector backfill slow and expensive. A generic “mission critical” flag captures the first effect and loses the second.

FIVE DATES INSIDE ONE LEASE

Every government-leased asset needs a five-date chronology.

The calendar gets more complex when the lease permits partial termination, contains rolling notice rights, amortizes tenant improvements on a separate schedule, grants renewal options, or supports multiple agencies. Mendria resolves the actual decision tree at the suite, lease, asset, loan, and fund levels.

The headline maturity becomes the least useful date whenever the firm-term end arrives first.

FIRM-TERM COVERAGE

Mendria calculates Firm-Term Coverage at the asset and loan level:

• Above 1.0x: protected rent extends beyond the longer capital horizon.
• At 1.0x: firm term and capital horizon end together, leaving limited execution margin.
• Below 1.0x: lender or investor capital extends into tenant-controlled term.
• At 0.0x: termination rights are currently exercisable.

Duration alone cannot price the exposure. Mendria adds three linked measures:

1. Soft-Tail Rent

The scheduled rent after the earliest effective termination date. This is the nominal cash flow controlled by the tenant's option.

2. Exercise probability

The quarterly probability that the government reduces, relocates, substitutes, consolidates, or exits. The model uses agency mission, local function, appropriations, staffing, utilization, facility replacement cost, geographic constraints, public procurement activity, and GSA's project calendar.

3. Loss given exercise

The rent gap, operating carry, decommissioning, restoration, tenant improvements, commissions, concessions, subdivision, security conversion, and rent reset after termination, net of another federal occupant, private reuse, sale, or alternative use.

The option-adjusted value of the lease can then be stated as:

This formulation avoids two common errors. Giving zero credit to every soft-term dollar can underprice a deeply embedded, actively used federal facility. Giving full credit can capitalize rent the tenant controls. Probability and severity belong in separate curves.

WHICH COUNTERPARTY NOTICES FIRST

The tenant agency and GSA planning team usually see the operating decision first.

An agency knows whether a field function remains funded, headcount is moving, public-facing service requires the location, secure work can transfer, a new facility is planned, or several offices can consolidate. GSA sees lease inventory, internal federal availability, prospectus requirements, agency demand, and procurement alternatives.

The owner can observe parts of that process before a formal notice:

• declining badge activity or staffed workstations where legally and operationally available;
• agency headcount and local hiring;
• appropriations and program reorganization;
• service-area demand and mission permanence;
• tenant alteration requests;
• deferred owner-funded work;
• GSA market surveys, sources-sought notices, and Requests for Lease Proposals;
• prospectus and Capital Investment and Leasing Program activity;
• nearby federal vacancies and lease expirations;
• consolidation announcements and replacement-site procurements;
• and the approach of the firm-term end.

GSA's March 2026 project-management order says prospectus-level lease project plans should enter the process ideally 48 months before lease expiration. Easterly describes the broader government leasing process as taking six to 36 months. The first public procurement signal can therefore emerge years before the current lease ends.

The first capital counterparty to translate that signal is often the lender. A five-year loan quoted with two years of firm rent exposes the lender to three years of tenant optionality. Credit can respond through proceeds, amortization, recourse, cash management, leasing reserves, future-funding conditions, or a shorter maturity. KBRA reported in 2025 that shifts in government policy had already influenced underwriting standards for GSA-leased assets and that recourse provisions were becoming more common.

The buyer follows the same path through price. It capitalizes protected NOI, probability-weights the soft tail, prices downtime and leasing capital, and tests private and federal backfill. The appraiser gains observable support once renewal negotiations, market surveys, lender terms, buyer bids, or actual terminations enter the record.

The conversion is direct:

WHEN THE SIGNAL BECOMES A TERM

The pricing event occurs in stages.

The highest-leverage window opens before GSA locks the space strategy and before a lender receives the application. Once the RLP, credit memorandum, or purchase agreement carries a downside case, the owner is negotiating against another party's clock.

HOW A 7.8% REPRICING CAN SIT INSIDE A “FULL-FAITH-AND-CREDIT” ASSET

Consider a transparent illustrative case. The inputs expose the mechanism and make no claim about a named property or a market-wide outcome.

Asset and lease

• 200,000-square-foot, single-tenant federal office.
• $6.5 million of in-place NOI.
• $100 million base value at a 6.50% capitalization rate.
• Seven years to stated lease expiration.
• Two years of firm term remaining.
• Owner seeks a new five-year loan.
• Earliest termination would fall three years before the requested loan matures.

Recovery case if the option is exercised

At a 30% exercise probability, the probability-weighted option cost is $7.8 million, or 7.8% of base value.

That figure is a modeled value exposure. It can appear through several counterparty terms:

These paths are alternatives. Stacking the $7.8 million price deduction, $5.0 million proceeds reduction, and a reserve would count the same risk several times. Mendria models the next counterparty, the term most likely to carry the risk, and the owner's cheapest credible intervention.

The action test is equally precise. Assume an owner can spend $2.5 million on targeted alterations, security modernization, consolidation work, or renewal economics that materially improve the agency's retention case. With a $26.0 million loss given exit, the program needs to increase retention probability by only 9.6 percentage points to break even before financing benefits:

The owner should fund the program when credible agency and GSA evidence supports an uplift above that threshold or when a lender confirms an additional proceeds benefit. The same math can reject an expensive renovation that leaves firm term, proceeds, and exit probability unchanged.

This is the investing decision: buy probability improvement for less than the value of the tail risk removed.

MISSION CRITICAL REQUIRES TWO UNDERWRITINGS

Government assets often carry a mission-critical label. Mendria splits it into retention and transferability.

Retention underwriting

• Is the agency function statutory, recurring, and locally required?
• Does the facility serve the public, adjudicate cases, process evidence, deliver veteran care, protect infrastructure, or operate continuously?
• How much has the government invested in tenant improvements, equipment, security, and technology?
• Can the function move without interrupting service?
• Does the labor force, jurisdiction, catchment area, port, border, laboratory network, or court district anchor the location?
• Is replacement space available within the required delineated area and security level?
• Would consolidation increase or reduce total mission cost?

Transferability underwriting

• Can another federal agency use the security envelope and circulation?
• Can secure areas become standard office without destructive work?
• Are labs, sally ports, evidence storage, raised floors, redundant power, or controlled access reusable?
• Can the floorplate divide efficiently?
• What restoration obligations follow surrender?
• Does local private demand exist at the required rent and suite size?
• What are expected downtime, concessions, commissions, and tenant improvements?
• Does alternative use require zoning, parking, life-safety, or structural work?

These dimensions produce four distinct investment profiles:

The most mispriced acquisition can sit in the high-retention / low-transferability quadrant. A broad office-risk screen may apply a severe haircut. A facility-level model can show replacement cost, mission continuity, agency capital invested, scarce alternatives, and a credible long-firm renewal path. The buyer acquires a feared tail at a basis that exceeds its probability-weighted cost.

The most dangerous “defensive” asset sits in the low-retention / low-transferability quadrant with a long stated expiration. The headline credit quality distracts from the tenant's option and the building's weak recovery.

THE DATA GRAPH A PROPERTY SYSTEM MISSES

GSA publishes a monthly lease inventory with region, location, lease number, expiration, occupancy percentage, annual rent, and other fields; its broader Inventory of Owned and Leased Properties covers more than 8,600 leased buildings and 1,500 government-owned buildings. GAO reported that GSA managed roughly 7,500 leases, 174 million square feet, and $6 billion of annual rent as of December 2024.

Those datasets establish the federal footprint and upcoming expirations. A complete model still requires firm-term dates, notice rights, suite rights, amortization, assignment provisions, Occupancy Agreement context, and the private agency decision path.

Mendria connects six graphs:

The portfolio screen then ranks assets by:

• stated WALE;
• firm-term remaining;
• Firm-Term Coverage;
• soft-tail annual rent;
• quarterly exercise probability;
• loss given exercise;
• probability-weighted option cost;
• debt proceeds at risk;
• alternative federal and private reuse;
• recommended action, cost, and deadline.

The result is a forward rent roll built around contractual control, with displayed duration preserved as a separate field.

THE OWNER ACTION WINDOW

The owner has five principal actions:

Extend protected duration

Trade targeted economics for additional firm term: rent structure, owner-funded alterations, consolidation support, phased work, energy or security upgrades, or a renewal package. The value comes from the incremental protected cash flow and better financing terms.

Move the capital event

Refinance or sell while sufficient firm term remains, shorten the requested loan, amortize through the risk window, or align debt maturity ahead of the tenant's first exit date.

Reduce loss severity

Pre-design subdivision, preserve reusable systems, secure restoration rights, obtain permits, prepare private-sector plans, and identify alternative agencies. A lower recovery cost increases asset value even when retention probability stays unchanged.

Create counterparty-ready evidence

Package the lease chronology, agency mission, utilization, government investment, replacement difficulty, federal alternatives, market recovery, and costed execution plan. Evidence can convert an open-ended reserve into a bounded reserve with release tests.

Buy the option cheaply

Acquire a soft-term asset when the market's implied exercise probability exceeds a facility-specific model and the owner has time to secure firm term or build reuse. The acquisition basis should reflect the full recovery case. The upside comes from probability convergence, renewal execution, and removal of uncertainty before the next capital event.

WHY EXISTING WORKFLOWS MISS THE WINDOW

The lease administrator records the stated expiration. Asset management tracks agency relationships. Government-affairs teams monitor appropriations. Property operations sees badge counts and alteration requests. Leasing watches GSA procurements. The capital-markets team sizes debt. Appraisers receive a snapshot near the transaction.

Each team holds one part of the option.

Soft term creates no missed rent during most of the hold. The lease can remain current, the building can remain occupied, and the government can remain highly rated. The economic change first appears as a shift in who controls duration. Conventional property systems lack a field for that control and a model for its probability-weighted cost.

The 2025 termination wave exposed the omission. The current 2026 data preserves the action window. GSA publishes thousands of leases and starts major planning years ahead. Public REIT disclosures show the measurable difference between headline and firm WALT. Agency budgets, facilities plans, procurement notices, utilization, and local federal inventory reveal the renewal path. Debt and hold dates reveal when the path becomes money.

Mendria's repricing graph joins the sequence before a term sheet does:

THE FALSIFIER

This call fails if government-leased assets with weak Firm-Term Coverage receive the same lender, buyer, and appraisal treatment as otherwise comparable assets whose firm term extends beyond the loan and hold period.

It also fails if mission, specialization, substitution capacity, and reuse evidence have no observable effect on renewal outcomes, reserves, proceeds, pricing, or time to backfill.

A partial result occurs if soft-term exposure predicts terminations while owner action and evidence fail to change the price. That would validate the risk screen and disprove the investing edge.

The call succeeds when three conditions hold:

• Firm-term end predicts capital terms more accurately than stated expiration.
• Retention and transferability explain meaningful differences within the soft-term cohort.
• Owners who act before GSA planning and capital-market deadlines secure more firm term, lower reserves, stronger proceeds, faster recovery, or better bids than comparable late movers.

HOW WE WILL SCORE IT

A clean pass requires all four. Tests 1 and 2 without Test 4 reveal repricing without a demonstrated Mendria intervention. A broad government-office discount that ignores lease rights and facility specifics fails Test 3.

THE FIVE QUESTIONS

THE INVESTING EDGE

The federal government can be the strongest credit in the rent roll and still hold the most valuable option in the lease.

Stated WALE tells an investment committee how long occupancy can continue. Firm-Term Coverage tells it how long current capital remains protected. Retention probability prices the agency decision. Transferability prices the building after that decision. Debt and hold dates determine which counterparty turns the difference into money.

The public portfolio evidence is already visible. Easterly reports 9.2 years including soft term and 8.0 excluding it. Eight government tenants generating approximately $16.9 million of annualized lease income can currently terminate before stated expiration. The company's explicit separation is the right starting point. The next step is asset-level forward pricing.

For the illustrative $100 million property, one contract date creates $7.8 million of probability-weighted value exposure while every rent payment remains current. A $2.5 million retention program needs less than a ten-point probability improvement to clear its first economic hurdle. A lender can move $5 million of proceeds through five points of advance rate before the government sends a notice.

That is the Mendria edge:

The lease says ten years. The government controls five of them. The next counterparty will price that control. The owner who models it first can decide whether to extend it, refinance ahead of it, cure its severity, or buy it at a discount.
