What Is a Rent Roll? A Guide to the Commercial Rent Roll
A rent roll is a schedule, kept by the landlord or its property manager, that lists every unit or suite in a property with its tenant, lease dates, and current rent as of a specific date. A commercial rent roll adds square footage, rent per square foot, escalations, expense recoveries, security deposits, and tenant options. Buyers, lenders, and appraisers all work from it, and it is only as accurate as the leases behind it.
What a commercial rent roll includes
Each row is a suite and each column is a lease term. Formats vary by owner, but most commercial rent rolls carry the columns in the sample below, from rentable square feet (RSF) and rent per RSF through expense recoveries, deposits, options, and a status column for arrears, free rent, or vacancy.
Illustrative example only: a fictional 40,000 RSF office building, as of October 1, 2026. The tenants and figures are made up.
| Suite | Tenant | RSF | Lease start | Expiration | Annual base rent | Rent / RSF | Escalation | Recoveries | Deposit | Options | Status |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 100 | Tenant A (coffee shop) | 2,500 | Oct 2017 | Sep 2027 | $95,000 | $38.00 | 3% per year | Net (pro rata share) | $15,000 | One 5-year renewal | Current |
| 200 | Tenant B (law office) | 12,000 | Oct 2021 | Sep 2031 | $420,000 | $35.00 | 3% per year | Base year 2022 | $70,000 letter of credit | One 5-year renewal; ROFO on Suite 350 | Current |
| 250 | Tenant C (engineering firm) | 8,000 | Oct 2026 | Sep 2031 | $264,000 | $33.00 | $1.00/RSF per year | Base year 2027 | $44,000 | Termination right, Sep 2029 | Free rent through Mar 2027 |
| 300 | Tenant D (software company) | 15,000 | Oct 2023 | Sep 2033 | $510,000 | $34.00 | 2.5% per year | Base year 2024 | $85,000 | Two 5-year renewals | 30 days past due ($42,500) |
| 350 | Vacant | 2,500 | — | — | — | — | — | — | — | — | Vacant |
| Total | 40,000 | $1,289,000 | 94% leased | ||||||||
The recoveries column is where commercial rent rolls get technical. Tenant A pays its pro rata share of operating expenses, a net structure, while the office tenants pay only increases over a base year; see the commercial lease types and how each one splits operating expenses. The options and status columns carry value too, such as Tenant B's right of first offer on the vacant suite and Tenant C's free rent.
How a commercial rent roll differs from a residential one
Most rent roll explainers are written for apartment owners. The purpose is the same; the content differs because the leases do.
Residential rent roll
Many units on similar standard leases. Rows show the unit type, monthly rent, lease dates (often 12 months or month-to-month), deposit, and balance owed. Any one lease is a small share of income.
Commercial rent roll
Fewer tenants on negotiated, multi-year leases. Rent is quoted per square foot, with escalations, recovery terms, and options that differ by tenant. One tenant can carry a large share of income, so one wrong row can move the valuation.
The risk is compression: a commercial lease with three amendments and a side letter does not fit on one row without losing something.
How buyers, lenders, and appraisers use a rent roll
Buyers use the seller's rent roll to underwrite in-place income, spot rollover, and decide which leases to review first. Purchase agreements often include a seller representation that it is accurate as of a stated date, which is a reason to test it, not accept it.
Lenders size loans on the income it shows and commonly require a certified rent roll and estoppel certificates from major tenants before closing.
Appraisers use it in the income approach, comparing in-place rent with market rent and basing vacancy and re-leasing assumptions on the expiration schedule.
Within an ownership group, legal and asset management teams use it to see which renewals, notices, and tenant rights are coming due.
How to analyze a commercial rent roll
Rent roll analysis asks where income could change, and when. Using the sample above:
Rollover and expiration concentration
Sort by expiration and total the area and rent expiring each year. Tenant A expires within 12 months, about 7% of base rent. The bigger exposure is September 2031, when Tenants B and C both expire: half the building and about 53% of base rent in one month. Tenant D alone is about 40% of base rent. Concentration like this should line up with the hold period and any loan maturity.
Weighted average lease term (WALT)
WALT is the average remaining lease term, weighted so larger tenants count for more. To weight by rent, multiply each tenant's remaining years by its annual base rent, add the results, and divide by total base rent. Here, (1 × $95,000 + 5 × $420,000 + 5 × $264,000 + 7 × $510,000) ÷ $1,289,000 is about 5.5 years. Count Tenant C's 2029 termination right as its end date and WALT drops to about 5.1 years. An average can hide a cliff year like 2031, so read it beside the expiration schedule.
In-place rent against market
Compare each rent per RSF with what comparable space leases for now. If similar space leases at around $36 (an illustrative figure), Tenant A at $38 may roll down next year, while Tenant D at $34 stays below market through 2033 and possibly through two renewals. Whether renewal rent is fixed or reset to fair market value is in the lease, not the rent roll.
Concessions, arrears, and vacancy
A rent roll shows contract rent, not cash. Tenant C pays no base rent until April 2027, so about $132,000 of first-year rent will never be collected, and a buyer will ask who bears free rent still running at closing. Tenant D, the largest tenant, is a month behind, the first question for the seller. And Tenant B's right of first offer means a new deal for vacant Suite 350 may have to be offered to Tenant B first.
Auditing a rent roll against the leases
A rent roll is the landlord's summary, only as current as its last update. The leases and amendments are what bind the tenant, and the two drift: an amendment never gets entered, an option window closes but the row stays the same, a deposit is drawn down after a default. A rent roll audit checks each row against the documents that govern it.
A line-by-line process
- Collect each tenant's full file: the lease, every amendment, side letters, commencement date acknowledgements, and any assignment or consent documents.
- Build the lease-side record from those documents rather than editing the rent roll, reading amendments in date order so each later change replaces the term it modifies.
- Compare row by row: tenant entity, suite, RSF, commencement and expiration, current rent and next increase, recovery structure, deposit or letter of credit, options and their notice deadlines, and concessions still running.
- Sort each difference: a document missing from the file, a rent roll error, or a fact only the tenant can confirm, such as whether rent is paid or an option was exercised.
- Confirm open items through tenant estoppel certificates prepared from the lease-side record, so tenants confirm what the documents say rather than what the rent roll says.
Mismatches that turn up most often
Rent or term changed by amendment
Extension, expansion, and relocation amendments often reset rent, add a new escalation schedule, or move the expiration. If the row still reflects the original lease, rollover and WALT are both wrong.
Options that no longer exist
Options usually require written notice by a deadline. Once the window closes without notice, the option is typically gone, yet the row often keeps it. The reverse also happens: an exercised renewal that never reached the rent roll.
Free rent and abatements left out
Abatements often sit in an amendment or side letter, not the main rent schedule, so the rent roll shows full rent for months when the tenant pays none.
Deposit amounts that differ
Deposits get reduced under burn-down clauses, applied to a default, or replaced by a letter of credit. A new owner is generally responsible for returning what the lease requires, so the amount transferred has to match the lease.
Also check square footage after a remeasurement or expansion, and the tenant's legal name after an assignment or merger. Option deadlines deserve the most care, since a missed notice window cannot be fixed later; they belong with the other critical lease dates asset managers track.
An estoppel certificate is the tenant's signed statement of its rent, term, deposit, and any defaults, and it generally limits the tenant's ability to claim different terms later. See how teams handle preparing tenant estoppel certificates and where this check fits in the lease side of commercial real estate due diligence.
Building the lease-side record with Abstria
The slow part of the audit is step two: reading every lease and amendment closely enough to know which terms are current. Abstria's AI lease abstraction software extracts 200+ fields from leases, amendments, and acknowledgements in 2-5 minutes per document, at 95%+ accuracy. Each field links to its source clause in the dual-panel editor, so a reviewer can confirm the terms that drive the deal and, where the rent roll disagrees, see which is right.
Deep Scan runs a second AI pass over each document, and the AI Lease Document Assistant answers plain-language questions across the leases, such as which tenants still hold renewal options. After closing, tracking how each amendment changes the lease keeps the record current.
Rent roll FAQ
What is the difference between a rent roll and a lease abstract?
A rent roll has one row per tenant across a property and shows income at a point in time. A lease abstract summarizes a single lease and its amendments in far more detail, including terms a rent roll never holds, such as assignment rights, exclusives, and notice requirements. Abstracts are a good source for checking a rent roll, not the other way around.
Who prepares a rent roll?
The landlord or its property manager, usually from the system where rent is billed. Many owners run one monthly. For a sale or refinancing, the seller or borrower typically produces a version dated close to closing, since rent, status, and arrears change month to month.
What is a certified rent roll?
A rent roll the owner or one of its officers signs as true, correct, and complete as of a stated date. Lenders commonly require one at closing, and purchase agreements may require one from the seller. Certification puts the signer behind the numbers; it does not make them match the leases.
What is WALT, and should it be weighted by rent or square footage?
WALT is the weighted average remaining lease term across a property's tenants, and both weightings are used. Weighting by rent shows how long income is secured; weighting by area shows how long space stays occupied. Some analysts measure to the first termination option instead of expiration, and some markets call the measure WALE (weighted average lease expiry). Always state the method.
