A revaluation clause resets rent or another property-linked payment on stated dates using the valuation method written into the contract.
A revaluation clause is a contract term that resets rent or another property-linked payment on specified dates using an agreed method. In commercial property leases, the more common label is often rent review clause. The clause may refer to open-market rent, a price index, fixed increases, tenant turnover, or another defined measure.
The label alone does not determine the result. The review date, formula, assumptions, caps, floors, notice procedure, and dispute mechanism written into the contract control the calculation, subject to applicable law. A revaluation clause does not guarantee that the revised amount will be fair, affordable, or equal to current market rent.
A lease may begin with a stated annual rent and identify one or more future review dates. At each date, the parties apply the contractual mechanism to determine the new rent. The revised amount may take effect automatically, by notice, by agreement, or after a valuation process, depending on the wording.
A complete clause normally answers these questions:
The economic effect can extend beyond the payment itself. A landlord may value the contractual income stream, a tenant may forecast occupancy cost, and a lender may assess whether the revised rent supports or weakens debt repayment capacity.
| Method | How the revised amount is determined | Main issue to verify |
|---|---|---|
| Open-market rent review | Estimates rent for the premises at the review date under assumptions written into the lease | Comparable evidence and the hypothetical lease terms |
| Index-linked review | Changes rent by movement in a named index, such as a specified CPI series | Exact series, reference months, lag, revisions, cap, and floor |
| Fixed or stepped rent | Uses amounts or percentage increases agreed when the lease is signed | Whether the schedule compounds and whether any review overrides it |
| Turnover or percentage rent | Links some rent to the tenant’s defined sales or revenue | Revenue definition, exclusions, reporting, audit rights, and base rent |
| Geared rent | Sets rent as a stated percentage of another rent or value measure | Definition and timing of the reference amount |
| Hybrid review | Combines methods, such as the greater of a fixed step and index result | Ordering of calculations and interaction of all limits |
These methods are not synonyms. A fixed increase does not establish market rent. An index-linked increase measures movement in the named index, not necessarily movement in the rent for a particular building. An open-market review requires property and lease evidence rather than a simple inflation calculation.
A simplified index-linked clause may use:
Where:
The actual agreement may use percentage change rather than an index ratio, average several months, introduce a publication lag, round the result, or apply a cap and floor. It should name the precise index series rather than say only “CPI.” Statistical agencies publish multiple indexes for different populations, geographies, item groups, and adjustment conventions.
The U.S. Bureau of Labor Statistics advises parties using CPI escalation to define the base payment, exact CPI series, adjustment frequency, formula, and method for handling revisions or discontinued series. BLS supplies statistical information but does not draft contract language or resolve contract disputes.
Assume a hypothetical commercial lease states:
$240,000;300.0;312.0;2.00%;5.00%; andThe raw index change is:
Because 4.00% lies between the contractual floor and cap, the revised annual rent is:
The annual increase is $9,600, or $800 per month before any tax, operating-cost recovery, or other lease payment.
If the review index were 318.0, the raw change would be 6.00%. Under this hypothetical clause, the 5.00% cap would limit revised annual rent to $252,000. If the raw change were 1.00%, the 2.00% floor would produce $244,800, assuming the floor is valid and operates exactly as described.
This example illustrates the calculation only. A real clause may use a different base, lag, averaging method, directionality rule, or cumulative cap. The governing lease should be read before applying any formula.
An open-market review estimates the rent that would apply at the review date under the hypothetical transaction defined by the lease. It is not necessarily the rent for a new lease on whatever terms are currently typical. The existing clause may prescribe assumptions and disregards that change the comparison.
Items that can affect an open-market review include:
The U.K. Valuation Office Agency notes in its rating guidance that reviewed rent reflects the terms of the particular lease and review clause. It also distinguishes a rent set by open-market review from a stepped rent agreed at commencement. That distinction matters because a reviewed rent is not automatically clean evidence of unrestricted market rent.
If the parties cannot agree, the lease may provide for an independent expert or arbitrator. These processes are not interchangeable. Their authority, evidence rules, procedure, costs, and ability to correct errors can differ by contract and jurisdiction.
The clause should state who can start the process, how the decision-maker is appointed, what deadline applies, and whether the determination is binding. A vague reference to an “appraiser” without a defined process can increase delay and dispute risk.
These features can cause contract rent to diverge from market rent or index movement. For example, if market rent falls from $250,000 to $235,000, a two-way open-market clause might permit the lower figure, while an effective upward-only floor at passing rent might retain $250,000. Whether that outcome is legally permitted depends on the agreement, jurisdiction, lease date, and current law.
Do not assume that a cap protects only the tenant or that a floor benefits only the landlord. A cap can affect property income and financing value; a floor can increase tenant occupancy cost and default risk. The overall lease economics matter.
For a landlord, a rent reset changes forecast Rental Income. If operating expenses do not change, an additional dollar of base rent may increase NOI by approximately one dollar. The actual effect depends on vacancy, collection, concessions, expense recoveries, taxes, and lease costs.
In the worked example, the annual rent increase is $9,600. If that entire amount were sustainable NOI and an analyst applied a 7.50% Capitalization Rate, the simple indicated value difference would be:
That is a sensitivity calculation, not a promised increase in sale price. A buyer may use a different cap rate or reduce value for tenant stress, near-term rollover, capital costs, or uncertainty about collecting the revised rent.
In a Discounted Cash Flow (DCF), the review date should be placed in the correct month, quarter, or year. The model should distinguish the effective date from the settlement date and reflect any retroactive catch-up payment consistently.
A review near the end of the Projection Period can also affect forward NOI and Reversionary Value. Capitalizing rent that has not yet been agreed, triggered, or supported can overstate terminal value.
Lenders may examine whether rent growth assumptions support debt service and whether a large reset could weaken the tenant. Important evidence includes the signed lease, amendments, review memoranda, comparable rents, index data, tenant financial information, and dispute status.
Contract rent above market may increase current cash flow but create rollover risk. Contract rent below market may suggest upside, but realizing it can depend on review rights, lease expiry, tenant retention, capital work, and local market conditions.
Tenants should distinguish base rent from total occupancy cost. A revaluation may interact with operating-cost recoveries, common-area charges, property taxes, insurance, percentage rent, sales tax, or other amounts. Forecasting only the headline rent reset can materially understate the full cost of occupying the property.
| Term | What changes | Main distinction |
|---|---|---|
| Revaluation or rent review clause | Rent or another stated property-linked payment | Umbrella contractual mechanism addressed by this article |
| Indexation clause | Payment based on a named index | Does not by itself establish open-market rent |
| Fixed escalation | Payment according to a preset schedule | Requires no fresh market valuation or index reading |
| Open-market review | Rent based on market evidence and lease assumptions | Result depends on the hypothetical terms in the clause |
| Lease renewal | Continuation or replacement of the lease | May involve new rent, but it is not the same event as an in-term review |
| Accounting asset revaluation | Reported carrying amount of an asset | Financial-reporting measurement, not a contractual rent reset |
| Property-tax reassessment | Tax authority’s assessed value | Government assessment process, not private lease pricing |
| Appraisal contingency | Transaction right tied to an appraisal result | Commonly affects closing obligations rather than periodic rent |
Outside leasing, a valuation clause can set the price for a shareholder buyout, purchase option, secured-collateral test, or another transaction. Those provisions may use appraisals but do not automatically follow rent-review concepts.
A mechanically correct calculation can still be legally inapplicable or financially unrealistic. Contract interpretation and valuation evidence should be reviewed separately.
