What Is a Rent Roll and Why Does It Matter in Commercial Real Estate?
A rent roll is the single most important document in commercial real estate underwriting. It provides a unit-by-unit snapshot of every lease in a property, showing who pays what, when leases expire, and how much income the building actually generates. For investors acquiring multifamily, office, retail, or industrial properties, rent roll analysis is the foundation of every financial decision.
Lenders rely on rent rolls to verify that a property generates enough income to service debt. Investors use them to identify upside potential, spot hidden risks, and negotiate purchase prices. Without a thorough rent roll analysis, you are essentially buying a property blind.

A complete rent roll typically includes tenant names, unit numbers, lease start and end dates, monthly and annual rent amounts, security deposits, rent escalation schedules, and any concessions or free rent periods. The best rent rolls also show lease type (gross, net, modified gross), renewal options, and tenant improvement allowances.
At Clearhouse Lending, we review rent rolls on every acquisition loan and permanent loan we underwrite. Our team has analyzed thousands of rent rolls across property types, and we consistently find that thorough analysis separates successful investments from costly mistakes.
What Are the Core Components of a Rent Roll?
Every rent roll should contain specific data points that allow for complete financial analysis. Missing or incomplete information is itself a red flag that warrants further investigation.
Core Rent Roll Components by Property Type
| Component | Multifamily | Office | Retail | Industrial |
|---|---|---|---|---|
| Tenant Name / Unit | Required | Required | Required | Required |
| Lease Start / End | Required | Required | Required | Required |
| Base Rent (PSF) | Required | Required | Required | Required |
| CAM / NNN Charges | N/A | Required | Required | Required |
| Percentage Rent | N/A | Rare | Common | Rare |
| Renewal Options | N/A | Required | Required | Required |
| TI Allowance | N/A | Required | Required | Occasional |
| Rent Escalations | Annual | Required | Required | Required |
| Security Deposit | Required | Required | Required | Required |
Tenant Information includes the legal entity name, contact details, and business type. For multifamily properties, this section is simpler. For commercial properties with retail or office tenants, understanding each tenant's business is critical for assessing credit risk.
Lease Terms cover the start date, expiration date, renewal options, and any termination clauses. Properties with staggered lease expirations carry less risk than those where multiple leases expire simultaneously.
Rent Details include base rent, percentage rent (common in retail), CAM charges, tax pass-throughs, insurance reimbursements, and any other income. The rent roll should clearly distinguish between gross rent and net rent.
Escalation Schedules show planned rent increases over the lease term. Fixed escalations (e.g., 3% annually) are more predictable than CPI-based escalations, which fluctuate with inflation.
Concessions and Abatements reveal any free rent periods, tenant improvement allowances, or other incentives that reduce effective rent below the stated contract rent. These details are frequently buried or omitted from summary rent rolls.
How Do You Compare Contract Rent to Market Rent?
Mark-to-market analysis is one of the most valuable exercises in rent roll review. By comparing each tenant's contract rent to current market rates, you can identify whether a property is under-rented (upside potential) or over-rented (downside risk).
To perform this analysis, gather comparable rental data from brokers, CoStar, or local market reports. Then compare each unit's in-place rent to the market rate for similar space in the same submarket. Express the difference as a percentage to quantify the opportunity or risk.
Under-rented units represent value-add potential. If market rents are $25 per square foot but a tenant pays $20, you can project a 25% rent increase at lease expiration. However, you must also consider the cost and probability of achieving that increase. Will the tenant renew at market rate, or will you face vacancy and re-leasing costs?
Over-rented units present the opposite risk. Tenants paying above market may not renew, leading to either vacancy or a rent reduction. Lenders are particularly cautious about properties where a significant portion of income comes from above-market leases.
When underwriting acquisition loans, Clearhouse Lending examines mark-to-market spreads carefully. Properties with meaningful below-market rents often qualify for value-add bridge financing, while stabilized assets with at-market rents fit better with permanent loan structures. Use our DSCR calculator to model different rent scenarios.
What Is Weighted Average Lease Term and How Is It Calculated?
Weighted Average Lease Term (WALT) measures the average remaining lease duration across all tenants, weighted by each tenant's share of total rental income. It is one of the most important metrics lenders evaluate because it indicates income stability.
WALT Calculation Process
Step 1
List each tenant's remaining lease term in years
Step 2
Record each tenant's annual rent amount
Step 3
Multiply remaining term by annual rent for each tenant
Step 4
Sum all weighted values from Step 3
Step 5
Divide total weighted value by total annual rent
WALT Formula: Sum of (each tenant's remaining lease term multiplied by their annual rent) divided by total annual rent.
For example, consider a property with three tenants:
- Tenant A: 5 years remaining, $200,000 annual rent
- Tenant B: 3 years remaining, $150,000 annual rent
- Tenant C: 7 years remaining, $100,000 annual rent
WALT = ((5 x $200,000) + (3 x $150,000) + (7 x $100,000)) / $450,000 = (1,000,000 + 450,000 + 700,000) / 450,000 = 4.78 years

A higher WALT means more predictable cash flow over a longer period. Lenders generally prefer properties with WALT of 5 or more years for permanent financing. Properties with shorter WALT may still qualify for bridge or transitional loans, where the business plan involves lease-up or renewal.
WALT is especially critical for single-tenant and net lease properties. A single-tenant building with 2 years remaining on the lease presents dramatically different risk than the same building with 12 years remaining.
How Should You Analyze Lease Expiration Schedules?
Lease expiration analysis reveals when income is at risk. A well-structured property has leases expiring in a staggered pattern, so no single year puts more than 15% to 20% of total rent at risk.
Lease Expiration Risk Assessment Matrix
| % of Rent Expiring in Year | Risk Level | Lender Response | Investor Action |
|---|---|---|---|
| 0% to 10% | Low | Standard underwriting | Monitor and budget normally |
| 10% to 20% | Moderate | May require explanation | Begin renewal discussions early |
| 20% to 30% | Elevated | Additional reserves likely | Active leasing strategy needed |
| 30% to 50% | High | Lower LTV or higher rate | Significant capital reserves required |
| 50%+ | Critical | May decline or require recourse | Consider lease-up bridge financing |
Lease Rollover Concentration is a critical risk factor. If 40% of your rent expires in the same year, you face the possibility of significant vacancy and re-leasing costs all at once. This concentration risk affects both your operating budget (you may need capital for tenant improvements and leasing commissions) and your ability to refinance.
Year-One Expirations deserve special attention during acquisitions. Tenants whose leases expire within 12 months of your purchase may already be planning to leave. Contact these tenants directly or through estoppel certificates to understand their intentions. Our tenant estoppel certificate guide explains this process in detail.
Renewal Probability depends on several factors: the tenant's business health, whether they have renewal options at favorable rates, the cost of relocation, and the availability of alternative space. Tenants with significant buildout investments are more likely to renew than those in generic space.
For each expiration year, model three scenarios: full renewal at market rate, partial renewal with some vacancy, and worst case with significant turnover. This stress testing gives you a realistic range of outcomes and helps you budget for leasing costs.
What Is Tenant Concentration Risk and How Do You Measure It?
Tenant concentration risk exists when a single tenant or small group of tenants represents a disproportionate share of property income. If your largest tenant accounts for 60% of rent and vacates, the property may not generate enough income to cover debt service.
Measuring Concentration: Calculate each tenant's percentage of total gross rent. Flag any tenant representing more than 20% of income as a concentration risk. For properties with fewer than five tenants, concentration risk is inherently higher.
Credit Analysis becomes essential for large tenants. Review their financial statements, payment history, and industry outlook. A property where 50% of rent comes from a Fortune 500 company on a 15-year lease has very different risk than 50% exposure to a local startup on a 3-year lease.
Mitigating Concentration Risk: Lenders may require higher debt service coverage ratios for properties with significant tenant concentration. Some lenders underwrite the property as if the largest tenant has already vacated, which dramatically reduces the supportable loan amount.
When applying for a refinance on a property with tenant concentration, prepare a detailed credit package on your major tenants. This includes financial statements, years in business, industry analysis, and any parent company guarantees. Proactive disclosure builds lender confidence and can improve your loan terms.
What Red Flags Should You Watch for in Rent Roll Analysis?
Experienced underwriters know that rent rolls can be manipulated, whether intentionally or through sloppy record-keeping. Here are the most common red flags that warrant deeper investigation.
Top 8 Rent Roll Red Flags
Recently Signed Leases at Above-Market Rates: If several new leases were signed just before the property was listed for sale, the seller may have inflated rents to boost the property's apparent value. These "sweetheart" leases sometimes involve related parties or tenants who received undisclosed concessions.
Unusually Low Vacancy: A property showing 100% occupancy in a market with 10% vacancy deserves scrutiny. The owner may have offered deep concessions or accepted unqualified tenants to fill space before selling.
Missing or Inconsistent Data: If the rent roll does not match bank deposit statements, tax returns, or the trailing-12-month operating statement, something is wrong. Always cross-reference the rent roll against at least two other financial documents.
Month-to-Month Tenants: A high percentage of tenants on month-to-month leases (beyond normal multifamily operations) suggests instability. These tenants can leave with minimal notice, creating sudden vacancy.
Deferred Maintenance Trade-Offs: Sometimes landlords keep rents artificially low in exchange for not addressing maintenance issues. The rent roll looks stable, but the property requires significant capital expenditure.
Tenant Improvement Allowances Due: Large outstanding TI commitments reduce the property's actual cash flow but may not appear on the rent roll itself. Always ask for a schedule of remaining landlord obligations.
Review our complete commercial due diligence checklist to ensure you catch these issues and more during your acquisition process.
How Does Rent Roll Analysis Affect Loan Underwriting?
Lenders use rent roll data to calculate Net Operating Income (NOI), which directly determines how much debt a property can support. The quality and stability of the rent roll influences every aspect of the loan, from interest rate to loan-to-value ratio.
How Rent Roll Quality Impacts Loan Terms
| Rent Roll Quality | Typical LTV | DSCR Requirement | Rate Premium | Loan Type |
|---|---|---|---|---|
| Institutional (A) | 70% to 75% | 1.20x | None | Permanent / Agency |
| Strong (B+) | 65% to 70% | 1.25x | +10 to 25 bps | Permanent / CMBS |
| Average (B) | 60% to 65% | 1.30x | +25 to 50 bps | Permanent / Bank |
| Below Average (C) | 55% to 60% | 1.35x+ | +50 to 100 bps | Bridge / Bank |
| Weak (D) | 50% or less | 1.40x+ | +100 to 200 bps | Bridge / Hard Money |
NOI Calculation: Gross potential rent (from the rent roll) minus vacancy and credit loss, plus other income, minus operating expenses equals NOI. Our NOI calculation guide provides a detailed walkthrough of this process.
Debt Service Coverage Ratio (DSCR): Lenders divide NOI by annual debt service to calculate DSCR. Most commercial lenders require a minimum DSCR of 1.20x to 1.25x. Properties with stronger rent rolls (long WALT, diversified tenants, at-market rents) may qualify for lower DSCR thresholds. Model your scenarios with our commercial mortgage calculator.
Loan Sizing: The rent roll determines the maximum loan amount through two constraints. The income approach (DSCR) sets one ceiling, while the value approach (LTV based on capitalized NOI) sets another. The lower of the two determines your loan amount.
Rate and Terms: Properties with institutional-quality rent rolls (investment-grade tenants, long lease terms, below-market rents) receive the best pricing. Properties with weaker rent rolls face higher rates, lower leverage, or additional reserves.

Whether you need help analyzing a rent roll for a pending acquisition or want to understand how your property's lease structure affects financing, reach out to Clearhouse Lending for a complimentary review.
Standardize Your Format: Create a master rent roll template that includes every data point you need. When you receive a seller's rent roll, re-enter the data into your template. This process forces you to examine every field and catches inconsistencies.
Cross-Reference Everything: Compare the rent roll against bank statements (do deposits match stated rents?), tax returns (does reported income align?), and estoppel certificates (do tenants confirm the lease terms?). Discrepancies between these sources reveal errors or misrepresentations.
Build a Lease Expiration Matrix: Create a visual timeline showing when each lease expires, color-coded by tenant size. This immediately reveals concentration in any particular year and helps you plan capital reserves.
Calculate Key Metrics: For every property, compute WALT, tenant concentration percentages, mark-to-market spreads, occupancy rate, average rent per square foot, and effective rent (after concessions). Track these metrics in a summary dashboard for quick comparison across properties.
Visit the Property: A physical inspection validates the rent roll. Walk every unit to confirm occupancy, condition, and tenant presence. Dark or empty spaces listed as occupied on the rent roll are an immediate red flag.
Request Aged Receivables: Ask for a report showing tenant payment history. Consistent late payments or outstanding balances indicate collection risk that the rent roll alone will not reveal.
Frequently Asked Questions About Rent Roll Analysis?
What information should a rent roll include? A complete rent roll lists every unit with tenant name, lease start and end dates, monthly rent, annual rent, security deposit, square footage, rent escalations, and concessions. Commercial property rent rolls should also include lease type (gross, net, NNN), CAM charges, renewal options, and any percentage rent clauses.
How often should a rent roll be updated? Rent rolls should be updated monthly at minimum. During a transaction, request a rent roll dated within 30 days of closing. Lenders typically require a rent roll certified by the property manager or owner within 15 to 30 days of loan closing.
What is a good WALT for commercial property? A WALT of 5 years or more is generally considered strong for commercial properties. Single-tenant net lease properties often have WALT of 10 to 15 years. Multifamily properties typically have shorter WALT (under 1 year) due to annual lease renewals, which is normal for that asset class.
How do you verify rent roll accuracy? Cross-reference the rent roll against tenant estoppel certificates, bank deposit statements, trailing-12-month operating statements, and tax returns. Physical property inspection confirms actual occupancy. Any discrepancies between these sources should be investigated before closing.
What tenant concentration level is considered risky? Most lenders consider any single tenant representing more than 25% of total rent as a concentration risk. Properties where the top three tenants account for more than 50% of rent may face stricter underwriting requirements, including higher DSCR thresholds or lower LTV limits.
How does vacancy affect rent roll analysis? Current vacancy reduces actual income below gross potential rent. Lenders apply a vacancy factor (typically 5% to 10% depending on property type and market) even for fully occupied properties to account for future turnover. Higher-than-market vacancy may indicate property issues, pricing problems, or management inefficiency.
Can a rent roll be manipulated? Yes. Common manipulation tactics include signing artificial leases before sale, hiding concessions, including related-party tenants at inflated rents, and omitting month-to-month tenants who plan to leave. Thorough cross-referencing and physical inspection are the best defenses against manipulation.
What is the difference between gross rent and effective rent? Gross rent is the stated contract amount. Effective rent accounts for concessions, free rent periods, and tenant improvement amortization. A lease showing $30 per square foot with 3 months free rent on a 36-month term has an effective rent of $27.50 per square foot. Always analyze effective rent for accurate underwriting.
