Why Concession Structure Shapes Long-Term Lease Economics
Tenants negotiating a commercial lease frequently focus on face rent while treating concessions as a bonus conversation. That framing misses the point. Free rent and tenant improvement allowances are structurally different instruments, and choosing between them changes not just your cash position in year one, but your total occupancy cost across the entire lease term.
What Free Rent Actually Delivers
Free rent is a time-based concession. The landlord agrees to waive base rent — and sometimes operating expenses — for a defined number of months at the start of the term. The tenant occupies the space but makes no payment, or a reduced payment, during that window.
The mechanics matter. Free rent accelerates cash preservation in the early period of occupancy, which is often when buildout is still underway, staff are being onboarded, and revenue from the new location has not yet materialized. For an occupier with tight near-term liquidity, that timing advantage can be meaningful.
What free rent does not do is reduce your face rent or change the contractual rate you pay in subsequent years. Once the abatement period ends, you revert to the full rent schedule. If that schedule includes annual escalations, your cost trajectory can rise sharply once the free period expires.
Free rent is also typically easier to negotiate cleanly. It requires no verification of construction spending, no draw process, and no landlord approval of contractor invoices. From a transaction-mechanics standpoint, it is the simpler concession to execute.
What a Tenant Improvement Allowance Actually Delivers
A tenant improvement allowance is a capital contribution from the landlord toward the cost of building out the space. It is typically expressed as a dollar amount per square foot — for example, a hypothetical allowance of $60 per square foot on a 10,000-square-foot space would represent $600,000 in landlord capital. The tenant uses that capital to fund construction, fixtures, cabling, and other improvements.
Unlike free rent, a TI allowance is tied to actual construction spend. Landlords require invoices, lien waivers, and often their own approval of the contractor and scope before releasing funds. Some leases allow the allowance to be drawn in phases; others require a single disbursement after substantial completion. Understanding the draw mechanics before executing the lease is as important as understanding the dollar amount.
A TI allowance effectively reduces your out-of-pocket capital outlay for the buildout. If the space requires $80 per square foot of work and the landlord provides $60, the tenant covers the remaining $20 from its own resources. The better the allowance, the less equity or debt the tenant needs to mobilize for construction.
One nuance that many occupiers miss is that TI allowances are often embedded in the rent rate. Landlords who offer a generous allowance frequently price it into the face rent, expecting to recover the capital through higher rent over the lease term. Evaluating the allowance in isolation — without comparing it to an alternative lease structure with lower rent and less allowance — can lead to a decision that looks attractive on the surface but costs more in total.
The Core Decision Framework: Effective Rent and NPV
To decide between more free rent and a larger improvement allowance, you need a common unit of comparison. Two methods do the heavy lifting: effective rent calculation and lease net present value analysis.
Effective rent converts all lease concessions into a single blended rate that can be compared across competing proposals. To calculate it for a free-rent scenario, you total the rent payments made over the full lease term and divide by the total number of months — including the free months. This gives you the average monthly cost, which can then be annualized and expressed as a per-square-foot figure for apples-to-apples comparison.
For a TI allowance scenario, the comparison is less direct because the landlord's capital contribution is received at a specific point in time — typically at or before buildout — rather than spread monthly. To convert the TI benefit into an effective-rent equivalent, you amortize the allowance over the lease term at the tenant's cost of capital. The resulting amortized benefit per square foot, subtracted from the face rent, gives you an effective rate comparable to the free-rent alternative.
Net present value analysis goes further by discounting all cash flows to a common point in time. This is the right method when comparing two leases where the cash outflows are timed differently. A lease with 12 months of free rent and no TI allowance produces a very different monthly cash flow profile than a lease with full rent from day one and a $70-per-square-foot TI allowance drawn in month two. NPV analysis applies a discount rate — typically the tenant's weighted average cost of capital, or a hurdle rate set by the CFO — to weight near-term cash differently from long-term cash.
Choosing Your Discount Rate
The discount rate you apply in an NPV analysis can swing the outcome of the free-rent versus TI-allowance comparison. Most corporate tenants use their weighted average cost of capital, but that figure can vary widely depending on capital structure and industry. A hypothetical rate of 8% produces a very different result than 12%.
If the company has access to cheap capital — say, it holds significant cash reserves and can self-fund construction at low opportunity cost — then the present value of a TI allowance delivered in month two of the lease is very high. The landlord's capital is nearly as valuable as the tenant's own, so maximizing the TI makes sense.
If the company's cost of capital is high, or if it anticipates needing external financing for the buildout, the present value of the TI allowance diminishes. In that case, the landlord is essentially providing expensive implicit financing embedded in a higher face rent, and the tenant may be better off taking more free rent, keeping face rent lower, and financing construction independently at whatever rate it can secure.
The discount rate is not a technical formality — it is the single biggest variable in the concession-structure decision. Every analyst building this comparison should run the NPV calculation at multiple rates and document the sensitivity, not just report a single answer.
Buildout Cost as the Starting Point
Before you can evaluate a TI allowance intelligently, you need a reliable construction cost estimate. Many tenants enter negotiations with only a vague sense of what their buildout will cost, which makes it impossible to assess whether a proposed allowance is adequate, generous, or insufficient.
A reliable cost estimate requires at least a schematic space plan and a preliminary budget from a qualified contractor or construction manager. In many markets, the landlord's base building condition — the state of the space before tenant improvements — varies significantly, and what looks like a raw shell may require substantial mechanical, electrical, and plumbing work before the tenant's own buildout can begin.
Once you have a credible cost estimate, you can calculate the gap between what the buildout will cost and what the TI allowance covers. If the gap is large, the tenant must fund it from equity, debt, or some combination. If the gap is small, the TI allowance is doing most of the work, and the effective economics of the deal shift accordingly.
Some occupiers treat the TI allowance as a ceiling for their buildout scope rather than a contribution toward a separately determined scope. This approach limits the quality and function of the space. The better practice is to define the space you need, price it accurately, and then negotiate the allowance required to fund it — rather than designing the space backward from what the landlord is willing to provide.
When Free Rent Is the Rational Choice
Free rent tends to be the better concession structure when the buildout cost is low relative to the lease value. Tenants taking mostly furnished or lightly improved spaces, or occupiers moving into a previously built-out suite that already fits their program, have little use for a large TI allowance. In that situation, free rent delivers real cash value that the tenant can put to work elsewhere.
Free rent is also the stronger choice when the tenant has near-term cash pressure. A startup that needs 90 days to ramp revenue, a professional services firm opening a new office ahead of client mandates, or a retailer absorbing pre-opening soft costs all benefit from a period of rent-free occupancy more than they would from a capital contribution they have already spent on construction.
There is also a risk argument for free rent. A TI allowance is only valuable if the construction project is executed well. Cost overruns, contractor disputes, or permitting delays can turn a generous allowance into an insufficient one. Free rent is unconditional — once the abatement period begins, the benefit is locked in regardless of what happens on the construction side.
Landlords, for their part, often prefer to give free rent rather than a large TI allowance. Free rent costs the landlord comparatively little on an NPV basis if they apply a low discount rate, because the forgone rent is deferred rather than paid out immediately. Understanding this dynamic helps the tenant negotiate: if free rent is cheap for the landlord, pushing for more of it is a reasonable lever before moving the conversation to cash.
When a Larger TI Allowance Is the Rational Choice
A larger improvement allowance makes the most sense when the buildout is capital-intensive and the tenant's alternative cost of capital is high. If the space requires significant construction investment and the tenant would otherwise fund it through expensive equity draws or credit lines, the landlord's capital is effectively cheaper and should be maximized.
TI allowances are also more valuable in longer leases. A $50-per-square-foot allowance amortized over a 10-year lease has a much smaller per-year burden on the landlord than the same allowance on a 5-year lease. This means the landlord has more room to be generous on TI in longer terms, and the tenant should push harder for capital contributions when committing to a longer occupancy.
There is a tax timing consideration as well, though specifics depend on the tenant's jurisdiction and structure. Tenant improvement expenditures may be depreciable assets on the tenant's books, and how the allowance is structured — whether received before buildout, reimbursed after, or structured as a landlord-paid-for-TI arrangement — can affect the accounting treatment. Tenants should engage their tax advisers before finalizing the concession structure, since policies vary and the right approach depends on individual circumstances that no general analysis can anticipate.
Finally, consider the buildout's residual value. Improvements that the tenant owns and can depreciate or recover have a different economic profile than improvements that revert to the landlord at lease end. If the improvements stay with the building, the tenant is effectively gifting capital to the landlord at the end of the term, which strengthens the case for maximizing the allowance upfront rather than preserving equity for improvements the tenant will not recover.
Running the Sensitivity Analysis
No single scenario tells the full story. A disciplined approach to the question of how to decide between more free rent and a larger improvement allowance involves running multiple scenarios and testing how the outcome changes across assumptions.
The key variables to stress-test are the discount rate, the buildout cost, the length of the free-rent period, the size of the TI allowance, and the face rent in each alternative scenario. Because landlords often offer the same headline economics through different concession mixes — more free rent on a lease with lower TI, or less free rent on a lease with higher TI and slightly higher face rent — the sensitivity analysis frequently reveals that the difference in NPV is smaller than the headline numbers suggest.
Where the sensitivity analysis is most useful is in exposing which assumptions drive the decision. If the NPV of the free-rent option is consistently higher across a wide range of discount rates, that is a strong signal. If the two options produce similar NPVs at low discount rates but diverge significantly at higher rates, the answer depends critically on the tenant's actual cost of capital — and the finance team needs to weigh in.
Document every scenario with its input assumptions. The discipline of recording why each assumption was made protects the analysis from being second-guessed after the fact, and it gives the deal team a clear audit trail if the recommendation is challenged internally.
Negotiating the Structure Once You Know What You Want
Once the financial analysis points to a preferred concession structure, the negotiation conversation changes. Instead of accepting whatever mix the landlord proposes, the tenant's adviser can table a specific counter that optimizes the chosen structure.
For example, if the analysis shows the TI allowance is more valuable, the adviser might offer to accept a modestly higher face rent in exchange for a materially larger allowance — framing this as a trade the landlord can justify because its NOI looks acceptable on paper even as it provides more upfront capital. Many landlords are receptive to this framing because higher face rent supports better leasing comps and, in some cases, better asset valuations.
Conversely, if free rent is the preferred structure, the adviser can propose a longer abatement period with a slightly lower TI, emphasizing that the landlord retains the improvement dollars on its balance sheet and avoids the administrative burden of the draw process. This can accelerate deal closing because the mechanics are simpler.
How the Choice Interacts with Lease Renewal and Portfolio Strategy
The concession structure at lease signing can affect the economics of future renewals. Free rent received in year one is gone by renewal time — it provided value, but that value has been fully consumed. A TI allowance, by contrast, may have funded improvements that remain useful and valuable at renewal, giving the tenant leverage to argue that a new allowance is warranted only for incremental changes rather than a full refresh.
On the other hand, if the face rent was elevated in exchange for a generous TI allowance, the renewal rent will typically be negotiated from that higher baseline. Over a multi-decade occupancy or across a multi-property portfolio, the cumulative effect of embedded TI costs in face rent can be substantial. Portfolio teams managing multiple locations should model the concession structure not just for the current lease but for the renewal terms they expect to negotiate.
Treating concession decisions as one-time events, disconnected from portfolio strategy, is one of the most common and costly mistakes in corporate real estate management. The lease you sign today shapes the negotiating position you will have in five or ten years, and the concession structure is part of that foundation.
Documenting the Decision and Communicating Internally
The concession structure decision is rarely made by a single person. In most organizations, the real estate team, the CFO or finance lead, and sometimes the operating business unit all have a voice. Bringing those stakeholders to a common understanding requires clear documentation of the analysis, not just a recommendation.
A well-structured decision memo covers the buildout cost estimate and its source, the discount rate used and how it was selected, the NPV and effective rent of each concession scenario, the sensitivity analysis across key variables, and the final recommendation with the rationale. It should be written so that a reader unfamiliar with lease negotiation can follow the logic without having to reconstruct the analysis from scratch.
The documentation discipline also matters for audit purposes. Real estate decisions involve material commitments, and being able to demonstrate that a concession structure was chosen through a rigorous, well-documented process — rather than intuition or expedience — protects the decision-makers and builds organizational confidence in the approach.
