A rent roll is a claim, not a record. Reviewing it means checking the claim against something the seller does not control.
Reading the document itself — unit by unit, what each line means and which figures to question — is covered in our walkthrough of how to review a multifamily rent roll. This is the next step: what to reconcile it against during due diligence, and what the gaps between those sources tell you.
Start With Deposits, Not the Roll
The most useful single check is also the least glamorous: add up twelve months of rent deposits into the operating account and compare the total to twelve months of contracted rent from the roll.
Contracted rent is what tenants agreed to pay. Deposits are what arrived. A gap of a few percent is ordinary — timing, a vacancy, a late payer. A persistent gap of ten percent or more means the building does not collect what its paperwork says, and that difference flows directly into value. On a 12-unit property contracted at $180,000 a year, a consistent 10% shortfall is $18,000 of NOI, which at a 5% cap rate is $360,000 of price.
Do this before commissioning anything expensive. It takes an afternoon with bank statements and it will tell you whether the rest of the exercise is worth running.
Then the Leases, One at a Time
Request the actual signed leases rather than the summary. You are not re-reading the roll; you are looking for what the roll does not carry a column for.
Concessions are the usual omission — a month free, reduced parking, a utility the owner absorbed to close a deal. None of these reduce the stated rent, so the roll shows a healthy figure while the tenant pays less. Side agreements are the other: a rent reduction in exchange for maintenance work, a pet fee waived verbally, a parking space thrown in. These rarely appear in any document you will be handed and frequently appear in the lease file.
Check the deposit held against each lease too. A roll that lists deposits the operating account cannot account for is a liability you inherit at closing.
Estoppels Are Where the Roll Gets Contradicted
A tenant estoppel certificate asks the tenant to confirm, in writing, what they pay and what they were promised. It is the only source in the entire process that does not come from the seller.
They come back inconsistent more often than buyers expect, and the inconsistencies are the point. A tenant states a rent lower than the roll. A tenant mentions an agreement about the garage that nobody disclosed. A tenant reports a deposit the seller has no record of. None of these automatically kill a deal — but each needs an explanation before closing, not after.
Send them early. They depend on tenants responding, which cannot be accelerated, and you want time for a second round on the units that do not reply.
Reconcile Against the Trailing Twelve
The rent roll is a snapshot of today. The trailing twelve months of operating statements show how the building behaved over a year, and the two should tell a consistent story.
Read the monthly income line rather than the annual total. A property presented as fully occupied whose income dipped for four months last year had vacancy the roll no longer shows. Occupancy that climbed sharply in the final two months before marketing is worth understanding — it may be genuine leasing, or it may be short-term tenancies and concessions placed to present a full building.
What the Lease Expiration Dates Are Telling You
Expiration dates are on the roll, but their significance only appears when you plot them against your closing date.
A building where a third of the leases expire within ninety days of close is not the stabilised asset the occupancy figure suggests — it is a building where you inherit the turnover. Equally, a cluster of month-to-month tenancies converted from fixed terms shortly before marketing tends to mean tenants were given flexibility to keep them in place through the sale. Both are manageable if modelled; neither is visible in a single occupancy percentage.
A Short Reconciliation Sequence
In the order that surfaces problems fastest for the least cost:
- Twelve months of bank deposits against twelve months of contracted rent
- Every signed lease against the roll — rent, term, deposit, concessions
- Estoppels issued to every occupied unit, early enough for a second attempt
- Monthly income on the trailing twelve against the current occupancy claim
- Expiration dates plotted against the closing date and the first twelve months of ownership
Keep a note of which figure came from which source and its date. When a discrepancy turns into a price conversation, the difference between a substantiated request and an apparent re-trade is whether you can show the working.
Questions Buyers Ask About Rent Roll Reconciliation
What if the seller will not provide bank statements?
It is a common refusal on smaller private deals and not always evasive — some owners keep informal records. Either way you are underwriting unverified income, so widen your assumptions accordingly. Tax filings, the property manager’s own ledger, or a redacted statement showing deposit totals can substitute partially.
How large a gap between contracted and collected rent is normal?
A few percent is unremarkable on almost any building. What matters more than the size is whether it is consistent: a single bad month is an event, the same shortfall every month is the building’s actual performance and should be underwritten as such.
Do estoppels matter on a small building?
Arguably more, because one misstated tenancy is a larger share of total income. On a six-unit property a single undisclosed concession moves the numbers materially, and the estoppel is the only place it reliably surfaces.
What if an estoppel contradicts the rent roll?
Treat it as a question rather than a conclusion. Tenants misremember, and rolls contain honest errors. Ask the seller to reconcile it in writing and to produce the document that supports their version. An unexplained contradiction at closing is one you own afterwards.
Should this happen before or after going into contract?
The deposit reconciliation can often be done pre-contract and is cheap enough to be worth it. Leases, estoppels and full statements normally require a contract and a contingency period, which is why the document request should go out on day one rather than once the third-party reports are back.
