Rent Roll

What Is a Rent Roll?

A rent roll is a detailed register of every rental unit in a property, providing a snapshot of the income picture at a given point in time. It typically includes unit numbers, tenant names, lease start and end dates, monthly rent amounts, security deposits held, pet deposits, any additional fees, and current occupancy status. For a fourplex, the rent roll fits on a single page. For a 200-unit apartment complex, it may span several pages and include additional fields like unit size, bedroom count, and market rent comparisons. The rent roll is the first document any serious buyer requests when evaluating an acquisition.

Why the Rent Roll Is Critical for Acquisitions

The rent roll drives property valuation. In commercial real estate, value equals NOI divided by cap rate, and NOI starts with gross rental income — which comes directly from the rent roll. A rent roll showing $10,000 per month in total rent produces a different valuation than one showing $12,000. The rent roll also reveals upside potential: units rented significantly below market represent an opportunity to increase income through lease renewals or turnover. Conversely, units rented above market may indicate future income decline. Every acquisition analysis begins with the rent roll.

How to Verify a Rent Roll

Never take a seller's rent roll at face value. Verify it through multiple sources. Request estoppel certificates from each tenant — these are signed documents where tenants confirm their lease terms, rent amount, and deposit. Compare the rent roll against actual bank deposit records for the past 12 months. Request copies of all current leases and compare them against the rent roll figures. Look for discrepancies: inflated rents, phantom tenants, missing concessions, or side agreements not reflected in the official rent roll. Experienced sellers sometimes "dress up" the rent roll before listing by raising rents or filling vacancies with friends and family.

Red Flags to Watch For

Be wary of a rent roll showing recent large rent increases just before listing — the seller may have jacked rents to inflate the property value without testing whether those rents are sustainable. Watch for tenants on month-to-month leases throughout the building, which could mean mass departures after closing. Multiple units with the same move-in date suggest the seller filled vacancies hastily to present a better occupancy picture. Any tenant paying rent in cash with no lease is a red flag. And if the total rent roll income does not match the bank deposits on the T-12, investigate why before proceeding.

Rent Roll vs. T-12

The rent roll and the trailing 12-month operating statement (T-12) are complementary documents that serve different purposes. The rent roll shows what is happening today — current rents, current tenants, current lease terms. The T-12 shows what actually happened over the past year — actual income collected, actual expenses paid, actual vacancy experienced. The rent roll tells you potential; the T-12 tells you reality. A property might have a perfect rent roll today but a T-12 showing chronic vacancy, collection losses, and high turnover. Always analyze both documents together to get the complete picture.

Using the Rent Roll in Your Analysis

Start by comparing each unit's rent against current market rents using Rentometer, Zillow rent estimates, or comparable listings. Calculate the total mark-to-market rental income — what the property would generate if every unit were leased at market rates. The difference between current rent roll income and market potential represents your value-add opportunity. Next, assess lease rollover risk by mapping lease expiration dates. If 60% of leases expire in the same month, you face significant re-leasing risk. Finally, factor in any below-market leases with long remaining terms that cannot be adjusted until renewal.
