Valuing Telecom Revenue in Multifamily Acquisitions

Telecom income is real NOI — and it is almost always mis-modeled

Telecom is one of the few line items an owner can add without renovating a unit, and it shows up in the sale price at the property cap rate like any other durable income. Yet in deal after deal it gets valued two ways that are both wrong: ignored entirely, or counted at its gross number as if every dollar the provider collects flows to ownership. This guide walks through the income streams, the incremental-versus-gross trap that inflates most telecom pro formas, and how to capitalize the piece that is actually yours — with the timing gate that decides whether any of it is accessible today.

Three ways a building earns telecom income

Before you can value it, you have to know which of three structures you are looking at. They are not interchangeable, and a single property can carry more than one.

Revenue share

Under a revenue-share arrangement — common in marketing agreements — the provider serves residents directly and pays ownership a percentage of the broadband revenue it collects, or a recurring fee tied to that revenue. Your income scales with two things you do not fully control: how many residents subscribe (penetration) and what they pay (ARPU, the average revenue per subscriber). A 10% share of a lightly penetrated building is a small number.

Door fees

A door fee is a one-time (or periodic) payment per unit for access or marketing rights — a fixed amount times the door count. It is simple and predictable, but it is also shallow: a one-time door fee is a lump sum, not a recurring stream, and capitalizing it as if it were annual NOI is a classic overstatement.

Bulk margin

In a bulk arrangement, ownership contracts for service to the whole building at a per-door wholesale rate and recovers a resident-facing amount (bundled into rent or billed to units). The income is the margin: the resident-facing rate minus the bulk cost, across effectively 100% of units. Bulk is usually the highest-value structure because it converts a partial, penetration-dependent share into a full-building margin — but only if the spread is real and the deal is structured well.

The mistake that inflates every telecom pro forma: counting gross

Here is the error that shows up in most models. Someone sees a bulk opportunity worth, say, $95,000 a year in margin, capitalizes it, and books a million-dollar-plus bump. The problem is that the building already earns telecom income today — a revenue share, a door fee, something — and that existing income is already sitting in the in-place NOI the buyer is paying for. Counting the full gross bulk margin on top of the price you are already paying double-counts the base.

The value of a telecom improvement is incremental: what the new structure earns, minus what the current structure already earns. Never the gross. This single discipline is the difference between a number a seasoned buyer will believe and one they will cross out.

There is a second, sharper version of the same trap. If a building is already on a bulk deal, its bulk margin is already in the in-place NOI. "Move it to bulk" is not an available improvement — it is already there. The only upside left is renegotiating terms at renewal, which is a smaller, later, and far less certain number. Booking a fresh full-margin uplift on an already-bulk building is how phantom value gets into a model.

Incremental value, worked

Numbers make it concrete. Everything below is illustrative — plug in your own property's figures.

The setup

• A 300-unit building, currently on a revenue-share marketing agreement.
• The provider pays ownership 10% of broadband revenue.
• ARPU is $60/month; penetration is 40%.

Current annual telecom income:

300 units × 40% penetration × $60 ARPU × 10% share × 12 months = $8,640 per year.

The bulk alternative

• Ownership contracts bulk service at a wholesale rate of $38 per door per month.
• Ownership recovers $65 per unit per month (bundled into rent / billed to units).
• Bulk margin per door = $65 − $38 = $27 per unit per month.
• Bulk applies to effectively 100% of units.

Gross annual bulk margin:

$27 × 300 units × 12 months = $97,200 per year.

The number that counts

The incremental income — the only piece that is genuinely new — is the bulk margin minus what the building already earns:

$97,200 − $8,640 = $88,560 per year incremental.

If you had booked the gross $97,200, you would have overstated the annual improvement by $8,640 and, capitalized, by roughly $157,000. The gap only widens as the current income gets larger.

Capitalizing the uplift

To translate recurring incremental income into value, divide by a capitalization rate. Using an illustrative 5.5% cap rate (a placeholder — use the rate appropriate to the asset and, if anything, a more conservative one for contract-dependent income):

$88,560 ÷ 0.055 ≈ $1.61 million of incremental value.

Two honest caveats sit on top of that figure. First, telecom income is only worth the property cap rate if it is durable and contract-backed; income that depends on a term expiring soon, on penetration holding, or on a provider's discretion deserves a haircut or a higher discount rate. Second, this capitalizes a steady-state margin — actual bulk deals carry install costs, hardware refresh obligations, and escalators that a real model should net out. The method is right; the inputs deserve scrutiny.

Timing is a gate, not a footnote

Even a clean incremental number can be worth zero today. You generally cannot restructure a building's telecom arrangement whenever you like — a bulk conversion or renegotiation realistically opens only as the current agreement approaches expiration, commonly in the window of about 12 months before it ends. Before that window, the incumbent deal governs and the uplift is a future option, not day-one value.

That has a direct underwriting consequence:

• If the current agreement expires within roughly a year, the uplift is close at hand and can be underwritten as near-term value.
• If it runs for several more years, the same uplift exists but is not accessible now. Model it as a future option — pushed out to the window when it actually opens and discounted for the wait — not as immediate NOI.

Skipping the timing gate is how a locked, multi-year deal gets a million-dollar day-one credit it has not earned. The expiration date is as load-bearing as the margin.

What to underwrite before you credit any of it

A telecom valuation is only as good as the contract facts under it. Confirm each of these before a dollar goes into the model:

• ☐Which structure is in place today — revenue share, door fee, or bulk — and what does it actually pay ownership?
• ☐Current penetration and ARPU, so the base income is measured, not guessed. These come from the provider, not the contract.
• ☐The incremental figure — new structure minus current income — never the gross margin.
• ☐Whether the building is already bulk. If so, the base margin is already in NOI and the only upside is a renewal renegotiation.
• ☐The expiration date and how far you are from the ~12-month restructuring window — is the uplift near-term or a discounted future option?
• ☐Any clause that blocks the change — an anti-bulk covenant, an exclusivity grant, or an early-termination cost — that would eat into the uplift.

Where the numbers come from

The inputs to this math are scattered across the contract, the exhibits, and the provider's own reporting — the pricing model, the revenue split, the term and expiration, and the penetration and ARPU that the paper never contains. Pulling them together property by property is exactly what a Telecom Intel Report does: it reads the in-place structure, models the incremental (not gross) bulk opportunity, applies the timing gate against the real expiration date, and hands you a valuation you can drop into underwriting. The same analysis runs continuously across a portfolio inside the platform, so the telecom line stops being the one number in the model nobody trusts.
