A broker shows you a federal requirement and says the magic words: ten-year lease. In a commercial deal, that phrase usually means ten years of committed rent. In a federal deal, it often means something very different: five years the government is committed to, plus five more years the government may take if it chooses. The headline term is not the guaranteed term. Confusing the two is one of the most expensive reading errors a landlord can make.
Federal leases are built in two parts. The first part is the firm term, the non-cancellable portion of the lease. The second part is everything after it: renewal option periods and any other time the government holds only as a right, not as an obligation. Landlords often call that second part the soft term. Whatever label you use, the economics are the same. You are guaranteed the firm term. Everything beyond it belongs to the government to exercise or decline.
What firm really means
The firm term is the government's commitment. During the firm term, the government is bound by the lease it signed, and rent is payable under that lease once the space has been accepted and the lease is in effect. That commitment is why federal leases are attractive in the first place: a reliable payer, paying by electronic funds transfer on a predictable schedule, for a period measured in years rather than months.
The commitment has a hard legal ceiling. By law, no lease may bind the government for more than 20 years. Within that ceiling, terms of ten, fifteen, or twenty years are routine, but the total is almost always split. A typical structure in a solicitation reads as 120 months total, structured as 60 months firm plus 60 months of options. Read that line the way an evaluator reads it: 60 months of commitment, and 60 months the government will evaluate again later, on its own timeline, against the market at that future date.
This split is not a technicality buried in the lease form. It appears on the face of the opportunity posting itself, alongside the delineated area and the square footage band. It is part of your first screen for a reason. If the firm term alone does not support your financing, the posting is telling you that on page one.
What happens after the firm term ends
Renewal options are the government's right, but not its obligation, to continue occupying the space beyond the firm term. When an option period approaches, the Lease Contracting Officer decides whether to exercise it. That decision is not automatic, and it is not a courtesy renewal.
Before exercising an option, the contracting officer follows prescribed procedures and reviews current market information to confirm the option rent is fair and reasonable. If the market has moved and the option rent no longer looks reasonable, the government can decline the option and return to the market with a replacing lease competition instead. An option priced below the future market is a gift the government will happily accept. An option priced above it may never be exercised at all.
Two more rules shape what you can and cannot assume. First, the option structure is set at award. An option that was not priced and evaluated at the time of award generally cannot simply be added in the middle of the term; adding it later requires full and open competition procedures. Second, the notice windows matter. Every option has notice dates defined in the lease. Calendar every one of them on the day the lease is signed, in a system that will still exist years later. You cannot exercise the option for the government, but you can make sure the timeline is never a surprise to you.
Where the soft term bites: tenant improvements
The firm and soft split would be a curiosity if it only affected rent projections. It becomes a real risk because of how tenant improvements are financed. In a federal lease, you finance the full buildout to the government-approved design: the walls, finishes, and fixtures that take the space from shell to finished, usable condition. The solicitation states a tenant improvement allowance per square foot, but the allowance is a pricing input, not a limit on what gets built. Costs above the allowance are recovered through rent over time.
The lease permits you to amortize tenant improvements and building-specific security capital over a period longer than the firm term. Spreading the cost over more years lowers the annual rent component and can make an offer look more competitive. Here is the catch, and it is worth reading twice: if the government terminates after the firm term, or does not renew or extend, the government is not liable for any unamortized costs beyond the firm term. For evaluation purposes, improvements are treated as fully amortized over the firm term, and the rent after the firm term must not reflect those improvement costs.
Put plain numbers on it. If you spread a large buildout over twenty years on a lease with a ten-year firm term, and the government leaves at year ten, the remaining unamortized balance is your loss. Not a negotiation point. Not a claim. Your loss. Spreading amortization past the firm term does not buy you an evaluated-price advantage either, because the government evaluates the improvements as if they were amortized over the firm term. It buys you risk, and only risk. Sometimes that bet is reasonable: many agencies stay in place for a long time, and a landlord who knows the agency and the building may accept the exposure deliberately. The mistake is making the bet without noticing you placed it.
The end of term is rarely a clean break
Landlords who model the end of the firm term as a cliff, with rent stopping and the space going vacant on a single date, model the wrong event. The federal end of term is gradual, and the lease gives the government several ways to stay while it decides what comes next.
The government can hold over after expiration, continuing to occupy the space and paying continuing rent. It can take a short-term extension while it negotiates a replacement lease, and short-term extensions while re-procuring are common. It can pursue a succeeding lease in the same building, negotiated with the incumbent, where a cost-benefit analysis shows that competition cannot recover the costs of relocation and duplication. Or it can run a full replacing lease competition, in which relocation and replication costs may be added to a challenger's evaluated price, giving the incumbent a structural edge, but never a guarantee.
None of this rescues a deal that was mispriced at the start. Holdover and extensions are bridges, not commitments, and they pay continuing rent, not a new firm term. What they should change is your planning: do not sign a replacement tenant on the assumption the government vacates on the expiration date, do not budget as though the rent stream ends cleanly at term, and do not count on a restoration payment when the government leaves. Many federal lease templates include a waiver of restoration, which means the buildout you financed generally stays in the building at no additional payment to you. The residual value of the improvements is whatever the next tenant will pay for them, and for agency-specific buildouts that value may be close to zero.
How to price the split, in practice
Disciplined landlords handle the firm and soft structure with three habits, all of them cheap and all of them before the offer goes in.
- Run the deal on the firm term first. Model debt service, taxes, insurance, the full buildout carry, and your required return using only the firm years, remembering that no rent is paid until the space is fit for occupancy. If the deal only works when every option is exercised, the deal does not work. Walk away or reprice it while walking away is still free.
- Match the amortization to the firm term, or price the gap on purpose. Amortize improvements and security capital over the firm term by default. If you choose a longer amortization to sharpen the offer, write down the unamortized balance at the end of the firm term and treat that exact number as capital at risk. Decide, in advance, that you can afford to lose it.
- Keep the building competitive for its whole life. The option decision years from now will test your rent against the market of that moment, and a replacing competition will compare your building against challengers. Maintenance, systems, and common-area condition during the firm term are end-of-term strategy. Treat the last two years of any federal lease as a re-marketing campaign for your own building, because that is what they are.
None of this makes the federal tenant a bad tenant. It makes the federal tenant a specific one: long-dated and reliable inside the firm term, and deliberately flexible beyond it, because agency missions grow, shrink, move, and consolidate, and the lease is built to let the government adapt. The landlords who do well in this market are not the ones who resent that flexibility. They are the ones who found the split on the first read, priced only what was guaranteed, and let the soft years be a bonus instead of a bet.
The total term on a federal lease is the government's flexibility. The firm term is your guarantee. Price the guarantee, and you will never be surprised by the flexibility.
