What is a rent roll and why should a buyer independently verify it before buying an income property?

A rent roll is a schedule, usually prepared by the seller or its property manager, listing each tenant in the building along with their unit, rent amount, lease term, and expiry date. It's essentially the seller's summary of the income the property generates. Because a buyer's offer and financing are often built directly around the numbers on this document, it functions as one of the most important pieces of information in the whole deal.

The reason it needs independent verification is simple: a rent roll is a summary prepared by an interested party, and summaries can be outdated, incomplete, or simply wrong, whether by honest error or otherwise. A buyer should cross-check every line against the actual signed leases, tenant estoppel certificates confirming the same figures directly from tenants, and the seller's bank or accounting records showing rent actually received, rather than accepting the document at face value.

Discrepancies between the rent roll and the underlying leases or estoppel certificates are a red flag worth investigating fully before closing, since a buyer who purchases based on an inflated or inaccurate rent roll can end up with materially less income than expected, with far less leverage to fix the problem after the deal has closed.
