Rent Roll and Lease Audit: Estoppels, Delinquencies and Concessions
The rent roll is one of the first documents an apartment buyer sees and one of the most important. It lists each unit, who lives there, what they pay and when their lease ends. It is also a document prepared by the seller, and it can be out of date, incomplete or optimistic. A rent roll audit tests that summary against the leases, the bank deposits and the residents themselves, so that buyers and their lenders can rely on the income they are underwriting.
This article is general information for buyers of existing, stabilized multifamily properties. It does not provide occupancy or collection benchmarks. Landlord-tenant, security deposit and rent regulation rules vary by state and locality, so lease questions should be reviewed with a qualified attorney. Nothing here is legal advice.
What a Rent Roll Should Show
- Unit number, type and size
- Resident name and whether the unit is occupied, vacant, a model or used by staff
- Lease start and end dates, or month-to-month status
- Contract rent and any other recurring charges
- Security deposits held
- Current balances owed and prepaid amounts
- Concessions, discounts or rental assistance payments
Match the Rent Roll to the Leases
Buyers or their attorneys typically review every lease, or a substantial sample on larger properties, and compare it with the rent roll. Discrepancies to watch for include rents that differ from the lease, missing renewals, unsigned documents, unusual addenda and side agreements such as promised improvements or reduced rent. Each lease should be in the name of the resident actually living in the unit.
Match the Rent Roll to the Bank
Scheduled rent is not collected rent. Comparing deposits in the property’s bank statements with the rent roll over a period of months shows whether residents are actually paying what the roll suggests. Our guide to multifamily operating statements explains how collections flow into the income figures lenders review.
Delinquencies and Collections
An aged receivables report shows who is behind and by how much. Buyers should ask how delinquent balances will be handled at closing, whether any residents are in eviction proceedings and whether payment plans are in place. Old balances may never be collected, and buyers generally should not count them as value. How delinquencies and evictions can be handled depends on local law, so counsel should be involved.
Concessions and Free Rent
A building may look fully leased at attractive rents while offering a free month, reduced first-year rent or other incentives that lower the cash actually received. Concessions should appear on the rent roll and in the leases, and buyers should consider whether they are likely to continue. Our article on multifamily property valuation explains why effective rent matters more than headline rent.
Tenant Estoppel Certificates
An estoppel certificate is a signed statement from a resident confirming key lease facts, such as rent, deposit, lease term and whether the landlord owes them anything. Purchase agreements sometimes require the seller to deliver estoppels from some or all residents, and lenders may ask for them. Estoppels can surface side deals or disputes before closing, though residents are not always required to sign them.
Security Deposits and Prepaid Rent
Security deposits belong to residents and generally must be transferred or credited to the buyer at closing, along with prepaid rent. Some jurisdictions have rules on how deposits are held, documented and returned. Buyers should reconcile the deposit ledger with the leases and bank records and confirm the handling with counsel.
Regulated Units and Assistance Programs
Some units may be subject to rent regulation or receive payments through rental assistance programs, which can affect how rents are set and changed. See our article on rent regulation and fair housing.
Fitting the Audit Into Due Diligence
The rent roll audit is one part of a broader review. Our apartment building due diligence checklist covers the rest. Sellers preparing for a sale can make this process smoother by keeping clean records, as described in our article on how to sell an apartment building.
