An above-market lease can provide valuable near-term cash while overstating durable income if its current rent is capitalized as though it continues indefinitely. Evaluate the remaining contractual premium separately from the property’s market-supported income. Then model expiry, renewal or replacement, downtime, improvements, commissions, and financing consequences.
The first question is whether the lease is actually above market on comparable economics. Compare effective rent, recovery obligations, space condition, concessions, term, and tenant credit—not just face rent per square foot.
Establish the comparison before labeling the lease
A tenant paying $30 per square foot under a gross lease is not directly comparable to a new tenant paying $22 under a lease with substantial expense reimbursements. A new lease with free rent and landlord-funded improvements also has different economics from an existing lease requiring little additional capital.
Collect relevant competing-space evidence and identify the tenant’s alternatives. Compare usable function, access, building systems, delivery condition, and permitted use. An industrial building’s power and loading or a medical office’s specialized improvements can make apparent rent comparisons misleading.
This guide provides no current Chicago market-rent estimate. Its figures are hypothetical. A real analysis needs dated evidence for the actual asset and tenant alternatives, with clear distinctions between asking rents, signed lease terms, and unverified broker commentary.
A hypothetical rent premium
Assume a 10,000-square-foot tenant pays $30 per square foot annually, or $300,000. Comparable supported market rent under equivalent expense terms is assumed to be $22, or $220,000. The annual premium is $80,000, and the lease expires at the end of year two.
If the tenant performs and no other changes occur, the investor receives that premium for two years. At an illustrative 10% annual discount rate, the present value of the two $80,000 year-end premiums is approximately $138,843.
Capitalizing the $80,000 premium at 7% as though it were durable annual income would imply approximately $1,142,857. That is a very different economic assumption. The comparison does not establish a complete property valuation; it illustrates why a finite premium should not be treated automatically as a perpetual income stream.
Separate current NOI from post-expiry NOI
Assume the property produces $400,000 current NOI, including the above-market tenant. If that tenant renews immediately at $220,000 with all other income and expenses unchanged, NOI falls $80,000 to $320,000.
At an illustrative 7% capitalization rate, current NOI indicates approximately $5,714,286, while $320,000 indicates approximately $4,571,429. A buyer who pays purely on the higher figure needs to understand why that pricing is justified despite the known reset.
A lease-by-lease DCF can show the actual timing more clearly. Include the remaining premium, the reset, capital costs, and exit condition. Do not add a separately calculated premium to a model that already includes the same contracted rent; that would count it twice.
Vacancy can create a deeper transition
Now assume the tenant leaves at expiry, the space is vacant for nine months, and a replacement begins paid rent for the final three months at the assumed $220,000 annual rate. First-year replacement rent is $55,000 rather than the original $300,000.
With all other income and operating expenses unchanged in this simplified example, NOI falls by $245,000, from $400,000 to $155,000. If tenant improvements and commissions total $172,000, cash before financing and other capital is negative $17,000.
Assume debt service is $250,000. The transition-year cash result becomes negative $267,000 before other reserves or obligations. The gap must be funded. A stabilized $320,000 NOI projection does not pay the transition costs that occur before it is achieved.
Renewal can be better than a higher face-rent replacement
Compare a supported renewal proposal with a replacement case over the same period. A lower renewal rent might avoid downtime, improvements, commissions, legal expense, and uncertainty. The highest quoted face rent is not necessarily the highest net present value.
Record the existing tenant’s actual rights, including any renewal option and its rent-setting mechanism. An owner cannot assume it can reset rent freely if the lease provides a different enforceable arrangement. Obtain appropriate interpretation of the actual clauses.
Also investigate whether the tenant can afford the current rent. A premium is valuable only if collectible. Arrears, disputes, declining business performance, or a weak guarantor can make the stated contractual income less reliable than the spreadsheet assumes.
Capital and reuse determine the reset economics
The space’s suitability for another tenant matters as much as the rent gap. A specialized buildout might have little value to the next user or require expensive removal. A restaurant, laboratory, medical suite, or single-purpose industrial space can create a different reuse challenge from a flexible shell.
Obtain scope and cost input for delivery. Identify landlord versus tenant responsibility and the timing of payment. A nominal tenant allowance can omit building-system work needed before the allowance is usable.

Financing may look beyond the current premium
A lender may use a different accepted income figure or focus on remaining lease term and expiry. Do not assume today’s high DSCR produces the same loan proceeds after the reset. Recalculate the proposed exit with supported post-expiry income.
If a loan matures near the tenant’s departure, the investment faces concentrated leasing and refinance risk. Model required reserves, paydown, or additional equity. Current cash generated during the premium years can help fund that risk if retained rather than distributed.

Price the premium with transparent assumptions
Use a base property forecast grounded in supported future rent, then identify the incremental contracted cash. Account for tenant performance risk, remaining term, and the cost of reaching the post-expiry condition. Explain the selected discount-rate and exit assumptions.
Avoid treating a low purchase price per square foot as proof of value if the income includes a rent premium and the building needs substantial work. Compare total cost, useful function, and realistic cash after capital. A building can be inexpensive relative to replacement cost and still overpriced relative to its earning capacity.
For a Chicago-area property, verify the legal and physical suitability of plausible replacement uses. Local approval or utility requirements can change the replacement schedule. Do not assume a particular municipal process or timeline without property-specific research.
An evidence and decision checklist
Before the inspection period ends, obtain the complete lease and amendments, payment history, tenant communication, relevant market evidence, and costed reuse plan. Identify notice deadlines. Separate facts from renewal assumptions.
Run three scenarios: continued performance to expiry followed by immediate renewal, delayed replacement at supported rent, and a longer vacancy with additional capital. Show the maximum funding need and the equity required at maturity in each.

The decision is whether the price compensates for the temporary nature of the premium and the cost of the next lease. The existing rent is a valuable contract when it performs. It should remain a dated cash flow in the model rather than quietly becoming a permanent assumption.
Monitor the remaining premium after closing
Track the lease’s remaining term, collections, tenant communication, and replacement readiness. Revisit market alternatives before the last months of the lease. If the business plan relies on retaining cash from the premium years, report the reserve balance and its intended uses separately from distributions.
A tenant’s renewal interest is useful evidence but not an executed agreement. Update the model when terms become concrete, and retain the comparison with replacement. That record helps owners evaluate the renewal decision on net economics rather than on whether it preserves the highest nominal rent.
Distinguish a rent premium from a special relationship
Investigate whether the lease arose from a related-party arrangement, sale-leaseback, unusual financing, or another transaction with economics beyond the real estate. A stated high rent may have been negotiated alongside a purchase price or business transaction. The investor should understand the tenant’s independent ability and obligation to pay rather than infer durability from the lease’s face amount.
Identify the actual obligor and guarantor. A familiar business name on a sign does not by itself establish that a well-capitalized parent company guarantees the lease. Confirm the documents and assess the available financial evidence. Where credit information is unavailable, acknowledge that uncertainty and test the property under replacement economics.
The same diligence applies to a tenant seeking an early rent reduction. Compare the proposal with the cost and timing of enforcement or replacement using appropriate professional input. A voluntary amendment changes the cash-flow contract and should be evaluated as an investment decision, not merely an administrative concession.
Separate the current tenant’s contractual payment obligation from the ability of a replacement tenant to sustain that rent. The first requires lease and credit analysis; the second requires evidence about competing premises and total occupancy costs. A strong answer to one does not resolve the other.
