Rent Roll Analysis for Office Properties

A rent roll is the itemized schedule of every tenant in an office building, their lease terms, and their rent obligations. For CRE investors, rent roll analysis is where underwriting begins — it determines whether the income stream supports the purchase price.

What an Office Rent Roll Should Include

A complete office rent roll includes:

• Tenant name, suite number, and floor.
• Rentable and usable square footage per tenant.
• Lease start date, expiration date, and remaining term.
• Current base rent (monthly and annual) and rent per square foot.
• Escalation schedule and next escalation date.
• Operating expense and tax pass-through obligations.
• Security deposit amount and form.
• Renewal and expansion option summaries.
• Vacancy and downtime assumptions for expiring leases.

Key Metrics for Office Rent Roll Analysis

Weighted Average Lease Term (WALT)

WALT tells you how long the income stream is contractually locked. Office buildings with WALT under 3 years carry re-leasing risk; buildings over 7 years offer stability but may lag market rents.

In-Place Rent vs. Market Rent

Compare each tenant's in-place rent per square foot against current submarket comps. Tenants paying below market represent mark-to-market upside at renewal. Tenants paying above market represent rollover risk.

Tenant Concentration

If a single tenant represents more than 25% of gross revenue, the building's value is heavily dependent on that tenant's credit and renewal likelihood. Quantify concentration risk explicitly, keeping in mind how it affects the property's capitalization rate.

Lease Expiration Schedule

Map expirations by year. Clustering of expirations in a single year creates simultaneous re-leasing risk and potential capital expenditure spikes for tenant improvements.

Net Effective Rent

Adjust gross rent for concessions — free rent, TI allowances, and moving costs — to calculate the true net effective rent per square foot over the lease term. This is the number that matters for underwriting.

Common Rent Roll Discrepancies

1) Stale Data

Sellers sometimes provide rent rolls that are weeks or months old. New leases, amendments, or move-outs may have occurred since the date shown. Always request the most current version and verify the "as of" date.

2) Missing Amendments

Rent rolls may reflect original lease terms without incorporating amendments that changed rent schedules, extended terms, or granted concessions. Cross-reference against lease abstracts.

3) Incorrect Square Footage

If the rent roll uses a different measurement standard or vintage BOMA calculations than the actual leases, per-square-foot metrics will be wrong. This affects rent comparisons and expense allocations.

4) Omitted Concessions

Free rent periods, rent abatements, and TI allowances reduce effective income but may not appear on the rent roll. Ask for a concession schedule separately.

5) Vacant Space Misrepresentation

Confirm whether "vacant" space is truly available or committed under signed leases that haven't commenced. Pre-leased space and space under negotiation should be disclosed separately.

Rent Roll Verification Workflow

1. Request the current rent roll with an explicit "as of" date.
2. Cross-reference each tenant against signed lease abstracts.
3. Verify square footage against building measurement records.
4. Calculate in-place rent vs. submarket comparables for every tenant.
5. Build a lease expiration schedule and flag concentration risks.
6. Request concession and TI schedules to calculate net effective rents.
7. Reconcile the rent roll against trailing-12-month operating statements.

FAQ

What is a good occupancy rate for office buildings?

Stabilized office buildings typically target 90–95% occupancy. Rates below 85% may signal market softness, management issues, or deferred capital needs. However, acceptable occupancy varies by submarket — Class A CBD buildings may sustain lower occupancy if in-place rents are high enough to support debt service.

How do you verify rent roll accuracy?

Cross-reference the rent roll against executed lease abstracts, trailing-12-month bank deposits, and operating statements. Estoppel certificates from tenants provide independent confirmation. Any discrepancies between these sources should be resolved before finalizing underwriting assumptions.

How often should a rent roll be updated?

Active asset managers update rent rolls monthly, at minimum. During an acquisition, buyers should request a rent roll dated within 30 days of the offer and again within 5 days of closing. Stale rent rolls are one of the most common sources of underwriting error.

What is the difference between a rent roll and a lease abstract?

A rent roll is a summary schedule listing all tenants and their key economic terms in a single document. A lease abstract is a detailed extraction of all terms from a single lease — critical for FASB ASC 842 compliance. Rent rolls are used for portfolio-level analysis; lease abstracts are used for lease-level verification and compliance.
