Receiving multiple proposals from competing landlords is not the moment to exhale — it is the moment where the real analytical work begins. A proposal that leads on headline rent can trail badly on effective economics once free rent, fit-out contributions, and escalation clauses are accounted for, and teams that skip a structured comparison often anchor to the wrong number at exactly the wrong time.
Why Headline Terms Mislead Without a Framework
Landlords construct proposals to look favorable at first glance. A lower face rate with steep annual escalations will frequently overtake a higher face rate that holds flat across the same term. Without a disciplined structure for comparison, advisers and occupier teams unconsciously weight whichever term surfaces first — a cognitive bias that negotiators on the other side of the table understand and routinely exploit.
The problem compounds when proposals arrive in different formats. One landlord may quote rent per square foot per annum on a net basis; another quotes gross per calendar month. A third bases the area on a different measurement standard. Before any term can be compared directly, the inputs must be normalized to a common unit, a common basis, and a common time horizon.
Normalization is not a cosmetic step. A net lease that prices operating expenses separately may carry a total occupancy cost materially higher than a gross lease with a higher face rate. Teams that build their comparison directly from the landlord documents, without restating every figure to a consistent basis, routinely reach conclusions that reverse once diligence is complete.
The first discipline of side-by-side comparison is therefore definitional: agree internally on exactly what you are comparing before you import a single number. That means settling on the measurement standard, the expense treatment, the base period, and the discount rate you will apply to present-value calculations — and locking those decisions before any landlord term goes into the model.
Establishing Your Comparison Template Before Proposals Arrive
The strongest teams build the comparison template before the first proposal lands, not after. When the template exists in advance, every proposal is loaded into the same structure, which removes the temptation to build a bespoke model that subtly favors whichever landlord submitted first.
A sound template captures at minimum: the usable and rentable area, the face rent for each year of the term, the treatment of operating expenses and taxes, the free rent quantum and whether it applies to net or gross obligations, the tenant improvement allowance expressed in both total dollars and dollars per usable square foot, any rent-free fitout period that sits outside the lease term, and the permitted use and assignment provisions.
Beyond those core fields, the template should capture optionality — expansion rights, contraction rights, renewal options, and early termination provisions. These terms have real economic value that does not appear in a cash-flow line, yet they directly affect the risk profile of each proposal. A proposal with a flexible termination right is structurally different from one without it, even if the cash flows print identically.
Finally, the template should carry a column for qualitative flags — zoning compatibility, building quality observations, landlord financial stability signals, and anything that affects the probability of the lease performing as written. Qualitative factors belong in the comparison structure, not in a separate document that gets separated from the numbers and lost before the decision meeting.
Normalizing Rent to Effective Annual Cost
Effective rent is the most important single figure in any proposal comparison, and it is rarely the number the landlord leads with. Effective rent annualizes the total economic cost of occupying the space across the full lease term, accounting for free rent, stepped increases, and the time value of concessions. Two proposals with identical face rates can differ by a meaningful margin on effective rent once those adjustments are applied.
The calculation starts by summing all rent obligations across the full term, then subtracting the value of any free rent periods. The result is the total net rent payable. Dividing by the total rentable area and by the number of years in the term yields the effective annual rent per square foot. That single figure makes proposals comparable regardless of their escalation structures.
Tenant improvement allowances complicate the picture because they represent a landlord subsidy of a capital cost the tenant would otherwise bear. The standard treatment is to express the allowance as an equivalent rent abatement — divide the total allowance by the rentable area and spread it across the lease term as a notional rent reduction. Adding that adjusted figure to the effective rent calculation produces a fully-loaded effective rent that reflects the economic exchange, not just the cash rent line.
Operating expense treatment must be normalized with equal rigor. On a net lease, ask for the landlord's current operating expense estimate and reforecast it at your expected growth rate across the full term. On a gross lease with an expense stop, model the gap between the stop and current gross expenses, because that gap is a hidden cost that accrues entirely to the tenant once expenses exceed the threshold. Only when all occupancy costs are captured on the same basis can the comparison be trusted.
Building the Net Present Value Model
Effective rent captures the average economic cost, but it does not capture the timing of that cost. A proposal that front-loads concessions and back-loads rent increases has a different present value than one that distributes the obligations evenly, even if the effective rent is identical. Net present value analysis closes that gap.
The NPV model discounts every future cash obligation to the current date using a rate that reflects either the tenant's cost of capital or the risk-free rate adjusted for the credit quality of the obligation. The choice of discount rate shifts the relative ranking of proposals, so it must be agreed and documented before the model is run — not adjusted after the fact to produce a preferred outcome.
Each proposal's NPV should be calculated on a gross occupancy cost basis, meaning rent plus operating expenses plus any capital contributions the tenant must make, minus the present value of landlord concessions. The resulting figure is the true economic cost of each option in today's dollars. When proposals of different terms are being compared — a five-year against a seven-year, for example — the NPV should be annualized or expressed on a per-square-foot basis to allow a like-for-like read.
Structuring the Side-by-Side Matrix
Once the normalized figures exist, the comparison matrix is the instrument that makes the decision readable. The matrix should organize proposals in columns and term categories in rows, with every cell containing a single, normalized figure drawn directly from the model. No narrative, no color commentary — just the numbers, restated to a common basis.
The rows should be grouped logically: area and measurement first, then annual rent by lease year, then operating expenses, then concessions, then optionality, then total occupancy cost, then NPV. That sequence follows the natural order in which an adviser or occupier lead works through a proposal, and it keeps the comparison readable for executives who were not in every working session.
A scoring matrix can sit alongside the financial matrix to capture the factors that resist quantification. Assign weights to criteria that matter for this specific requirement — proximity to transport, floor plate efficiency, building amenity, landlord covenant strength, fitout flexibility — and score each proposal against each criterion. The weighted score does not override the financial analysis, but it surfaces trade-offs that the NPV model cannot express. A property that scores significantly higher on operational criteria at a small NPV premium may represent the better decision once those factors are properly weighted.
Every cell in the matrix should carry a reference to its source — a page and clause in the proposal document. Teams conducting documents and diligence on a shortlist of properties know that extracted terms shift between proposal, letter of intent, and final lease, and the comparison matrix needs to be updateable at each stage without rebuilding from scratch.
How to Compare Proposal Terms Side by Side Across Different Lease Structures
Gross leases and net leases are not the only structures in play. Modified gross leases, full-service gross leases, triple-net leases, and absolute net leases each allocate operating risks differently, and proposals that mix these structures cannot be compared without first resolving what each tenant actually pays. This is where many side-by-side analyses break down, because teams attempt to compare the rent line without reconciling the expense allocation.
The cleanest method is to convert every proposal to a full-occupancy-cost basis. For a triple-net proposal, add the landlord's current year operating expense estimate and apply a hypothetical growth rate — three percent per annum is a common working assumption, though the actual rate should reflect local market conditions and asset type. For a gross proposal with an expense stop, calculate the estimated overage in each year of the term. For a full-service gross, confirm exactly what the all-in rate includes and whether utilities, janitorial, and management fees sit inside or outside the quoted figure.
Once all proposals are on a full-occupancy-cost basis, re-run the effective rent and NPV calculations using the restated figures. The ranking of proposals often changes at this step, sometimes dramatically. Practitioners who have watched a net-lease option that appeared cheapest become the most expensive after expense normalization understand why this step is non-negotiable.
Escalation structures deserve a separate row in the matrix even after normalization. A fixed-step escalation — three percent per year, hard-coded — is a different risk from a CPI-linked escalation, which transfers inflation risk to the tenant. In a stable inflation environment the two may track closely; in a period of elevated inflation the CPI-linked structure can produce rent levels materially above what a fixed-step would have generated, and the NPV analysis at lease execution will have underestimated the liability.
Evaluating Concession Packages
Tenant improvement allowances are the largest concession in most commercial proposals and the one most frequently misread. The gross allowance figure is not the economically relevant number. What matters is the allowance net of the tenant's expected fitout cost — the surplus or deficit — and the degree to which any surplus can be applied to soft costs, furniture, or rent abatement, versus being forfeited if unspent.
Free rent periods carry a similar complexity. Free rent applied to base rent only has a different value from free rent applied to all occupancy costs including operating expenses. Free rent during a fitout period where the space is not yet operationally occupied has a different value from free rent on an already-fitted space that the tenant is immediately occupying and generating revenue from. The comparison matrix should distinguish between these cases explicitly.
Landlord early access periods — intervals during which the tenant can begin fitout before the lease commencement date — are a concession with real value that rarely appears in the headline terms. Quantify each landlord's early access offer in terms of equivalent free rent days, and add it to the concession package total for comparison purposes. A proposal that appears to offer less free rent may be economically equivalent or superior once the early access period is expressed on a consistent basis.
Lease renewal options and expansion rights should be treated as option value, not ignored or treated as binary. A renewal option at the then-prevailing market rate has limited value in a rising market but significant value in a flat or falling market. An option to expand into adjacent space on pre-agreed economic terms has calculable value if the probability of needing that space within the option window can be estimated. Assign a probability-weighted value to each optionality provision in the matrix, and include it in the total-value-to-tenant calculation.
Managing the Revision and Counter-Proposal Cycle
Proposals rarely end at their first submission. Landlords revise in response to counter-proposals, and the comparison matrix must be able to absorb those revisions without losing the audit trail of what changed between rounds. Teams that rebuild the matrix from scratch with each revision lose the ability to track which concessions moved and by how much — information that is essential for knowing when a negotiation has reached its limit.
Version control in the comparison matrix means assigning a date and round number to each proposal state, retaining prior versions, and recording the delta between rounds alongside the current figures. When a landlord improves the TI allowance by a specific amount while worsening the escalation structure, both movements should be visible in the record so the net economic effect can be assessed cleanly.
Counter-proposal strategy depends on knowing the relative position of each landlord in the comparison. The adviser who can show that one proposal is within a specified margin of the preferred option on NPV — and that a targeted movement in two specific terms would close the gap — is negotiating from analysis rather than from instinct. That precision requires the comparison matrix to be current, accurate, and accessible to the advisory team in real time.
The review-before-outreach discipline is particularly important in this cycle. Any counter-proposal that references specific figures from the comparison matrix should be reviewed against the source documents before it is sent, because transposing a figure between the matrix and the negotiation document introduces errors that can be difficult to retract once in writing.
Incorporating Market Context Into the Comparison
A proposal comparison conducted in isolation from market context is incomplete. The question is not only which proposal is best among the options received — it is whether the best option is acceptable relative to what the market would deliver for a comparable requirement.
Market context means knowing the current effective rent range for comparable space in the relevant submarket, the typical concession package being offered by landlords for comparable transactions, the vacancy rate that is driving landlord behavior, and any large lease expirations or supply events that may shift market conditions during the occupier's decision window.
Benchmarking against market does not require perfect comparability. A representative sample of recent transactions of similar size, term, and quality tier in the relevant market is sufficient to establish whether the best proposal is at, above, or below market. When a proposal is materially above market on any term, that gap is a negotiating input, not just an observation. Document it in the comparison matrix with a source reference, and use it explicitly in the counter-proposal narrative.
Structuring the Client Presentation
The comparison analysis exists to support a decision, and the decision belongs to the occupier or investor, not the adviser. Translating the matrix into a presentation that a board or C-suite can act on requires a different structure from the working model — one that leads with the recommendation, supports it with the key financial differentials, and surfaces the qualitative trade-offs without burying them in detail.
The presentation should open with the recommended option and the two or three financial reasons it ranks first on a total-occupancy-cost and NPV basis. It should then present the runner-up scenario with the specific gap — expressed in total cost and in annual equivalent terms — and explain what term movement would be required to close that gap. This structure respects the decision-maker's time while preserving the analytical basis for scrutiny.
Supporting slides or pages can carry the full matrix for those who want to interrogate the inputs, but the decision narrative should be self-contained. A decision-maker who reads only the lead pages should understand what the recommendation is, what it costs, why it is preferred, and what the alternative costs if the recommendation is not available or acceptable.
Where the recommendation involves material qualitative trade-offs — a shorter walk to transport at a higher cost, or a less-efficient floor plate at a lower rate — those trade-offs should be stated plainly and quantified wherever possible. A floor plate efficiency differential that requires an additional headcount of space to accommodate the same number of workstations has a calculable cost in additional rent and operating expenses that belongs in the comparison, not in a footnote.
Maintaining the Comparison Through Diligence and Execution
The proposal comparison does not end when a preferred option is selected. The terms in the proposal must survive the letter of intent stage and the final lease negotiation, and the comparison matrix should be maintained through both. Material deviations between the proposal and the executed lease represent a failure of the diligence process, not an administrative oversight.
Key terms to track from proposal through execution include: the final rent schedule against the proposed schedule, the final TI allowance quantum and application rules against the proposal, the final escalation mechanism against what was proposed, and the final option terms against what the comparison model captured. Each of these has a financial consequence if it drifts, and the drift should be flagged and quantified in real time rather than discovered at lease audit.
Landlord option windows, due diligence periods, landlord consent requirements, and board approval timelines all carry deadlines that, if missed, can alter the economics of the transaction or eliminate the preferred option entirely. The calendar is not a formality — it is a risk management instrument.
