Multifamily Utility Reimbursements and NOI

Multifamily utility reimbursements are tenant payments toward utility bills the owner pays. They can increase net operating income (NOI), but the calculation must count each recovery only once. If reimbursements appear as income, the corresponding expense must include the cost before those reimbursements. Including reimbursement income while deducting an expense already reduced by the same payments overstates NOI.

Where reimbursements appear on the statement

Keep reimbursements identifiable within other operating income, separate from apartment rent. Fannie Mae’s August 2024 Form 4254.DEF includes reimbursements and utility income under Other Income and defines NOI as effective gross income minus operating expenses, before debt service and replacement-reserve deductions. Its utility expense definition covers owner-paid costs net of rebates, with water and sewer reported separately. A utility-provider rebate should not be confused with a tenant reimbursement.

Freddie Mac’s July 2026 PRS CREFC reporting guide explicitly requires full utility costs on the expense side and tenant reimbursements in Other Income. That is a specific reporting requirement; it does not establish how a seller has prepared its statement.

For multifamily investment analysis, reconstruct both sides before accepting the seller’s total. “Utilities” could mean the original cost or the owner’s remaining cost after recoveries.

Gross and net presentations should produce the same NOI

Hypothetical illustration: An apartment property reports the following for the 12 months ended August 31, 2026. Assume cash accounting, $600,000 of rent and other receipts excluding utility reimbursements, $90,000 of owner-paid utility costs, and $36,000 of reimbursements collected. Other operating expenses are $250,000, including all billing-service fees. There are no utility rebates or timing adjustments.

In the net column, the $36,000 of collected reimbursements reduces utility expense from $90,000 to $54,000 and is removed from income. NOI remains $296,000 because only the presentation changes. This is an analytical reconciliation, not a substitute for a lender’s required gross reporting.

The error column keeps both the reimbursement income and the expense reduction. It counts the same recovery twice, overstating NOI by $36,000.

To convert the net column to gross, add $36,000 to both income and expenses. NOI should remain unchanged. If it rises during that conversion, check whether the expense was restored.

Trace the utility costs and tenant payments

Request utility invoices, general ledger detail, the tenant charge-and-payment ledger, billing-vendor remittances and bank deposit records for the same period. Reconcile three amounts:

1. Owner utility costs: Match invoices and ledger entries. Identify provider credits, unpaid invoices and bills covering another period.
2. Tenant recoveries: Locate reimbursements in income accounts, expense credits and any amount bundled into another line. Map each recovery to one treatment.
3. Billing costs: Check whether the vendor withheld its fee before remitting collections. If income is grossed up for that fee, include the matching expense once.

A low utility expense alongside reimbursement income warrants investigation, but does not prove an error. Efficiency improvements, occupancy changes or different service periods could also explain the amount. Request documentation before making an adjustment.

Do not create owner reimbursement income for a bill the tenant pays directly to the utility provider when neither the bill nor payment passes through the owner’s accounts.

Distinguish billed amounts from collections

Use collections to establish what the property actually received. A tenant charge ledger establishes amounts billed; reconcile it to payments before treating the entire billed total as historical cash recovery.

For an accrual statement, request a receivables reconciliation rather than simply replacing its income line with cash receipts:

Opening utility receivables + charges − credits and write-offs − collections applied = closing utility receivables.

Review aged balances and subsequent payments to distinguish billing delays from amounts unlikely to be collected. Separate receipts for earlier periods from current-period charges so a catch-up collection does not look like a permanent improvement.

Document whether the final analysis uses cash receipts, accrual income with collectibility adjustments, or the lender’s prescribed method. When comparing rental operating economics, maintain the same accounting basis and period across income and expenses.

Separate proposed recoveries from accepted loan assumptions

A proposed ratio utility billing system, commonly called RUBS, belongs in a forecast until its results are established. Show eligible units, charge assumptions, start dates, expected collection losses and billing costs separately from historical operations. Ask local counsel to confirm the lease provisions and applicable billing restrictions before relying on new charges.

A reporting classification does not guarantee that a lender will accept the projected amount. Fannie Mae’s conventional-loan income-analysis requirements, effective June 2, 2026, require other income to be stable, customary in the market and supported by prior years, excluding extraordinary nonrecurring items.

Specialized provisions also need to stay within their scope. Fannie Mae’s solar photovoltaic system requirements, effective June 2, 2026, limit reimbursement income by the trailing 12-month amount and require consideration of reductions associated with lower utility expense. That solar provision does not establish a universal reimbursement ceiling for every apartment loan.

Ask the lender to identify its accepted reimbursement amount, the matching utility expense and any adjustments from the seller’s NOI.

How double counting changes cap rate and indicated value

A capitalization rate relates annual NOI to property price or value. The OCC’s commercial real estate lending handbook defines the rate using stabilized NOI and sales price. Label whether your own calculation uses historical or projected NOI.

At a hypothetical $5 million purchase price, the example’s reconciled historical NOI produces a 5.92% cap rate: $296,000 ÷ $5,000,000. The double-counted figure produces 6.64%, an overstatement of 0.72 percentage points.

If an analyst instead capitalized both figures at an assumed 6%, the $36,000 error would inflate indicated value by $600,000: $36,000 ÷ 0.06. That is a sensitivity calculation, not a market valuation or promised sale price.

Calculate cap rate using reconciled NOI, and keep the supporting utility reconciliation with the result so the income and expense treatment can be checked.
