Ancillary revenue conversations in multifamily usually stop at the operating statement. The program produces income, the income lands in other income, other income rolls into net operating income, and the discussion moves on.
The part that gets skipped is the one that matters most to an owner. At disposition, an underwriter decides how much of that other income is real. Some of it is accepted into the underwritten figure. Some of it is discarded. The tests are published, they are specific, and most operators have never read them.
This article is about those tests. It does not estimate what any portfolio’s non-rent revenue is worth, because that number depends on your own audited figures and your own market. What it does is explain what determines whether the number counts at all.
Why this question got more important
The rent side has been doing very little of the work.
Yardi Matrix reported that the average United States advertised rent “rose $4 to $1,771” in its most recent monthly release, describing “a 1.3% year-to-date increase in advertised rates over the past five months” and “year-over-year rent growth remaining weak amid a record number of apartment deliveries.” RealPage Analytics characterized the longer arc as “rent growth running below 1% year-over-year for nearly 30 months,” alongside average concessions reaching “the equivalent of 36 days of free rent.”
The expense side has not been as accommodating. The National Apartment Association reported that “average annual rent reached $21,502 per unit in 2024, rising just 1.2% from 2023, following growth of 2.9% in 2023 and 11.4% in 2022,” and that “since 2021, repairs and maintenance costs have risen nearly 28%, while Net Operating Income (NOI) has increased just 10% during the same period.”
When rent growth is flat and expenses are not, the composition of net operating income becomes a live question rather than an accounting detail.
How value is actually set
The mechanism is simple and worth stating precisely, because the precision is where the operational requirements come from.
CBRE defines it directly in its cap rate survey work: “stabilized cap rates are the ratio of stabilized net operating income (NOI) to the acquisition price of the asset.” The Freddie Mac Multifamily Seller/Servicer Guide sets out the same approach in its valuation chapter, noting that “the Property’s value can be developed with either a multiplier analysis or direct capitalization analysis,” and that the “capitalization Rate must be based on factors reflecting the investment characteristics of knowledgeable investors for properties similar to the Property.”
So value follows underwritten net operating income. Which means the operational question is narrow and answerable: how much of your non-rent revenue survives into the underwritten figure.
On where cap rates currently sit, CBRE reported core multifamily going-in cap rates at 4.75% and exit cap rates at 4.95% in its Q4 2025 survey, with value-add going-in at 5.26% and value-add exit at 5.38%. Note that the exit cap is published separately from the going-in cap, which is the whole point of this discussion. The exit assumption is where a buyer’s view of durable income shows up.
What the agencies actually require
Both agencies publish their treatment of other income, and the language is unusually clear.
The Freddie Mac Multifamily Seller/Servicer Guide, at Section 60.17(e), states that “the appraiser may include income from sources other than residential units when calculating total gross income if such income is supported by at least three years’ historical operations, is common in the market and is expected to continue in the future.” The Guide lists examples including “commercial space, laundry, parking, cable television, vending and application fees.”
The Fannie Mae Multifamily Selling and Servicing Guide, at Section 203.01, applies comparable tests to underwritten net cash flow. Other income must “be stable” and “be supported by prior years,” and the underwriter must “exclude one-time extraordinary non-recurring items.” The Guide requires an assessment of “the individual month’s other income within the prior full-year operating statement or, at a minimum, an operating statement covering at least the trailing 6 months (annualized),” and constrains how fluctuating income can be used: “if there are fluctuations, you may use other income that exceeds the trailing 3-month other income (annualized), provided it does not exceed the highest 1-month other income used in the trailing 3-month other income calculation.”
Read together, four tests emerge. The income has to recur. It has to be documented across periods. It has to be normal for the market. And anything one-time gets stripped out.
Translating the tests into operations
Those four tests are underwriting language. Each has an operational equivalent that an operations team can act on.
Recurrence means the revenue has to be produced by a process rather than by an effort. If the income exists because a particular regional manager runs a good program, it will show gaps the moment that person changes roles, and gaps show up as fluctuation in exactly the trailing-period tests the agencies apply.
Documentation means the transactions have to live in a system of record, attributable to a property and a period. Revenue reconstructed from vendor statements at diligence is revenue an underwriter will discount, because it cannot be tied to the property’s own books cleanly.
Market normalcy means the services should be ones a buyer recognizes. Movers, packing, storage, insurance, utilities and connectivity are services residents in residential real estate buy during every move. Their presence in other income reads as ordinary rather than as an aggressive assumption.
Excluding one-time items means promotional pushes and one-off campaigns should be understood for what they are. They may be good business. They will not carry into an underwritten figure, and treating them as if they will produces a valuation conversation that goes badly.
Where most programs fail
Four patterns account for most of the gap between reported non-rent revenue and underwritten non-rent revenue.
The revenue sits in a single undifferentiated other income line. When a buyer asks what is inside it, the answer takes weeks to assemble and arrives incomplete. A category nobody can decompose is a category a buyer discounts.
The program varies across the portfolio. Different offer sets by region produce a consolidated number that fluctuates for reasons unrelated to demand, and fluctuation is precisely what the agency trailing-period tests penalize.
Attribution is missing. Vendor-side reporting shows totals. Property-level, period-level attribution is what an underwriter needs, and it has to come from the operator’s own records.
And the revenue depends on human memory at the point of the move. Any process that requires a leasing associate to remember an offer during a busy move-in and move-out period will produce inconsistent results, which reads as instability in the numbers regardless of the underlying demand.
Traditional tools focus on task tracking and administrative coordination. Moved embeds revenue-generating services and insurance verification directly into the workflow.
The reporting standard worth holding
An operator who wants non-rent revenue to count at disposition should be able to produce, on request, four things.
A breakdown of other income by service category rather than a single line. Monthly figures across a multi-year history, matching the periods the agencies test. Property-level attribution for every dollar. And a written description of the process that generates the revenue, showing it does not depend on any individual.
That package is what turns a program into an underwritable income stream. Without it, the revenue is real in the operating statement and absent from the valuation.
Frequently asked questions
Does other income really affect valuation, or does the buyer just look at rent?
Both agencies explicitly permit other income in the underwritten figure when it meets their tests, and CBRE’s definition ties value directly to net operating income. The constraint is on quality of evidence rather than on the category itself.
How many years of history do we need?
Freddie Mac’s appraisal guidance references “at least three years’ historical operations” for other income sources. Fannie Mae’s underwriting tests work off the prior full year or, at minimum, a trailing 6-month operating statement annualized, with additional constraints on fluctuating income. Building the record early is the practical takeaway.
We are not selling for years. Does this matter now?
The history requirement is the reason it matters now. A three-year record cannot be created retroactively at the point of sale. The operators who benefit are the ones who instrumented the revenue several years before anyone opened a data room.
What is the single highest-value change to make first?
Move the revenue into a system of record with property-level and category-level attribution. Every other test becomes answerable once the data exists, and none of them are answerable until it does.
Closing
Non-rent revenue reaches valuation through net operating income, and only the portion an underwriter accepts makes the trip. The tests are published by both agencies and they reward the same things: recurrence, documentation, market normalcy, and the absence of one-time items. Those are operational properties. They are built into how the revenue is generated and recorded, years before the exit cap is ever negotiated.
