Every self-storage offering package is built on the rent roll, and every buyer treats it as the income. It is not. A rent roll is a list of what tenants have agreed to pay, and the distance between that and what a facility actually collects is where most of the surprises in a storage acquisition live.

Key takeaways

• A rent roll records what tenants agreed to pay, not what the facility collects. Promotions that never stepped up, tenants who stopped paying, free and owner units, and rate increases that were sent but never applied all sit on the roll at full value.
• Twelve months of bank statements, reconciled to the collections report, is the only monthly record not produced by the seller. It answers every question the rent roll dodges, once non-rent income like insurance commissions and fees is pulled back out.
• On a 350-unit facility at 90 percent occupancy, an ordinary set of gaps can remove about $60,000 of annual income the package treats as real, worth $850,000 to a million dollars at storage cap rates.
• The roll can hide upside as well: long-term tenants far below street rate signal an undermanaged property. Price off what the facility collects today, plan off what it could collect.

Ask for the financials on a self-storage facility and the first thing that arrives is the rent roll. It lists every unit, its size, whether it is rented, who is in it and what they are paying. Multiply the rented units by their rates, add it up, and the number at the bottom is what the broker calls gross potential income. The pro forma starts there, the offering price is set from there, and the lender sizes the loan from there.

The rent roll is useful. It is also the most flattering document a seller can produce without saying anything false. It records agreements, not deposits. Whether the rates on it are what tenants are really paying, whether those tenants are paying at all, and whether the income it implies bears any relationship to the money that showed up in the bank last month are separate questions that the roll is not designed to answer. A buyer who does not ask them is underwriting the seller’s description of the property rather than the property.

Why the rent roll flatters

The rent roll overstates income in four ways, and the point is not that any one of them is dishonest. It is that all four push in the same direction, and the seller has no reason to correct for them.

The first is promotional rates. Nearly every facility rents new tenants at a discount: the first month free, half off for three months, a web-only rate well below the posted one. Those promotions are supposed to expire and step up to the regular rate. In practice, a share of them never do, because the software was not set up to step them, because a manager forgot, or because the tenant called to complain and the manager gave in. The rent roll shows the contracted rate. The tenant is paying the promotional one. On a facility that has been leasing aggressively to fill up before a sale, the share of the roll still sitting at an introductory rate can be substantial, and every one of those units is contributing less than the roll says.

The second is that the roll counts units, not payers. A tenant who has not paid in three months is still on the rent roll at the full contracted rate, because the unit is still occupied. The delinquency side of this has its own article, but the point here is simpler: the rent roll cannot tell the difference between a tenant and a lock. Income on the roll attached to a unit whose tenant has stopped paying is not income. It is a vacancy that has not been processed yet.

The third is the units that are on the roll but were never going to produce rent. The manager’s unit. The owner’s boat. The unit the landscaping contractor gets free in exchange for mowing. The units that hold the facility’s own golf cart, spare doors and Christmas decorations. The unit a relative has had since 2011 at a rate nobody has touched since. On a small facility these can add up to a meaningful share of what the roll presents as occupied income, and they vanish the day the new owner takes over, either because the arrangement ends or because the buyer inherits a tenant who expects it to continue.

The fourth is the quietest and, over time, the most expensive: rates that were set but never collected. Storage is a month-to-month business, and the rate on a long-standing tenant’s agreement is whatever the last increase letter said. Whether the tenant actually started paying the increased amount is another matter. Autopay cards that were set at the old rate, tenants who kept paying the old amount and were never chased for the difference, and increases that went out on paper but were never applied in the software all produce a roll that shows a rate the bank has never seen. The larger operators have turned existing-customer rate increases into the engine of their revenue growth, which means a buyer expects that engine to be running. On many privately owned facilities it is not, and the rent roll is where the gap hides.

The number that does not lie

There is one document the seller cannot dress up, and it is the one buyers ask for last: the bank statements.

Twelve months of deposits, reconciled against the management software’s monthly collections report, answer every question the rent roll dodges. If the roll implies $58,000 a month in rent and the bank has been receiving $49,000, the difference is the sum of every promotion that never stepped up, every non-payer, every free unit and every increase that was never applied, and no amount of explanation from the seller changes the arithmetic. The buyer does not need to find each individual cause to know the size of the problem. The bank statement is the answer key.

The reconciliation matters in the other direction too, because the bank statement can also contain money that is not rent. Tenant insurance commissions, late fees, administrative fees, lock and box sales, truck rental and the occasional auction proceeds all flow through the same account. Some of that is real, recurring income that a buyer should underwrite. Some of it, like late fees at a facility with a delinquency problem or a one-time insurance settlement after a roof claim, is not. And on facilities that share an owner with other properties, deposits from a sister facility have a way of landing in the wrong account. A buyer who takes the bank statement total as the income has made the opposite mistake to the buyer who took the rent roll, and needs to pull the non-rent items back out.

What the exercise produces is a number the offering package does not contain: what this property actually collects in rent, from tenants who actually pay, at rates they actually pay. That number is what the buyer is buying. Everything else is a projection.

What the gap costs

Take a 350-unit facility that the offering package describes as 90 percent occupied with an average rate of $140. The rent roll supports it: 315 rented units, gross potential income of about $44,000 a month, roughly $530,000 a year, and a price set off that figure.

Now suppose the reconciliation shows that 25 of those units are still on an introductory rate averaging $95, that 18 are more than a month behind, that 6 are employee, owner or trade-out units producing nothing, and that a rate increase sent to 80 long-term tenants in the spring was applied to about half of them. None of this is unusual for a facility that has been run by a single owner-operator for a decade. Worked through, the property collects something closer to $39,000 a month from paying tenants, or about $470,000 a year. The gap is roughly $60,000 of annual income that the seller’s package treats as real. At the capitalization rates storage trades at, that is a difference in value somewhere between $850,000 and a million dollars, on a facility that might be priced at seven.

The seller is not necessarily lying about any of it. Every unit on the roll is occupied. Every rate on the roll is the contracted rate. The package is accurate as a description of the agreements in place. It is simply not a description of the income, and the difference belongs to whoever fails to check.

Why the seller’s income statement does not fix this

Buyers who know the rent roll is soft often turn to the seller’s profit and loss statement instead, on the theory that a P&L records what was collected. Sometimes it does. Often it is generated by the same management software from the same rent roll, on an accrual basis that books rent when it is charged rather than when it is paid, and it inherits every one of the problems above. A P&L that shows rent income tying exactly to the rent roll month after month is a P&L that has never met the bank account.

The tax return is closer to the truth, because owners have less incentive to overstate income to the IRS than to a buyer, but it arrives late, it is annual, and it mixes the facility with whatever else the owner runs through the entity. The bank statement remains the only monthly record that was produced by someone other than the seller.

The roll can hide upside too

For balance, the rent roll is not only a source of bad news. The same document that overstates collections can understate what the facility should be collecting, and for the same reason: it records agreements rather than the market. A facility whose long-term tenants are sitting at rates well below what the operator across the street is posting has a rent roll that looks weak and a business that is undermanaged, which is a very different thing. The large operators routinely carry in-place rates far above their move-in rates because they raise existing tenants steadily; a private owner who has not sent an increase letter in three years has left that money on the table, and a buyer who can see it has found the thing that justifies the price.

The point is that the rent roll, read on its own, cannot tell a buyer which of these two properties it is looking at. Read against the bank statements and against current street rates in the trade area, it can. One comparison tells the buyer what the property really earns today. The other tells the buyer what it could earn. The purchase price should be set from the first and the business plan from the second, and the seller’s package tends to blur the two.

The takeaway

A rent roll tells a buyer what a facility could collect if every tenant paid every contracted dollar on time. That is a useful ceiling and a poor estimate. The income a buyer is actually purchasing is the amount that lands in the bank from paying tenants at the rates they really pay, and the only way to know it is to put the rent roll next to twelve months of deposits and account for the difference.

Most of the time the difference is manageable, and knowing it simply sharpens the price. Occasionally it is large enough to change the decision. In either case it is knowable, it is cheap to find, and the seller already knows it. The buyer who reads the rent roll as an income statement has agreed to pay for the version of the property that exists on paper. The one who reconciles it has agreed to pay for the property.
