Lease Types and Structures
Ground Lease: A lease of land (rather than a building) in which the tenant is permitted to construct improvements. In cell tower contexts, this is the most common lease structure - the carrier or tower company leases your land to build and operate a cell tower. Ground leases create a property interest that is more durable and harder to terminate than license agreements.
License Agreement: A contractual permission to use property for a defined purpose without creating a property interest. Cell tower licenses are less favorable to property owners than ground leases because they are more easily terminated. If a carrier proposes a license agreement, negotiate to convert it to a lease structure.
Easement: A legal right to use another's property for a specific purpose. Cell tower easements are sometimes used for access roads or utility runs to tower sites. Permanent easements can affect property ownership in ways that ground leases do not.
Rooftop Lease: An agreement permitting a carrier or tower company to install equipment on the roof or exterior of a building. Rooftop leases are common in urban markets where freestanding towers are not feasible.
Small Cell License/Lease: An agreement for compact, low-profile antenna installations on buildings, utility poles, or streetscapes - the building blocks of 5G dense networks.
DAS (Distributed Antenna System): A network of antennas connected to a common source that provides wireless coverage inside or around a specific venue or area. DAS leases typically involve a more complex physical installation than traditional cell towers.
Financial and Valuation Terms
Escalation Clause: The lease provision specifying how rent increases over time. Usually expressed as an annual percentage (e.g., "3% per year") or tied to an index like CPI. The single most financially impactful term beyond the base rent itself.
CPI (Consumer Price Index): A government measure of inflation. CPI-linked escalation ties rent increases to the actual rate of inflation, protecting the real purchasing power of your income.
Co-tenancy Fee / Co-location Fee: An additional rent payment triggered when a second or subsequent carrier is added to a tower on your property. A critical but often-absent provision in older leases.
Discounted Cash Flow (DCF): A valuation methodology that calculates the present value of a future income stream by discounting future payments at a defined rate. Used by buyout companies to calculate their offers.
Discount Rate: The rate used in DCF calculations to convert future payments to present value. Higher discount rates produce lower present values. Buyout companies use 8-12% discount rates; independent market valuations use market cap rates of 4-6%.
Cap Rate (Capitalization Rate): The ratio of annual income to asset value (Income / Value = Cap Rate). Cell tower lease assets have recently traded at 4-6% cap rates in institutional markets. Used in independent valuations to determine market-based present value.
Present Value: The current value of a future stream of payments, calculated by applying a discount rate or cap rate to the projected income.
Net Present Value (NPV): The present value of future cash flows minus any initial investment. Used to compare the financial merits of keeping a lease versus selling it.
Parties to a Cell Tower Lease
Landlord / Lessor: The property owner who grants the lease rights. You.
Tenant / Lessee: The carrier or tower company that leases the property. American Tower, Crown Castle, AT&T, Verizon, T-Mobile, etc.
Tower Company / TowerCo: A company that owns cell tower infrastructure and leases space to carriers. American Tower, Crown Castle, SBA Communications, and Vertical Bridge are the largest tower companies in the US.
Wireless Carrier / MNO (Mobile Network Operator): A company that operates a wireless network. AT&T, Verizon, and T-Mobile are the three major US MNOs. They may be your direct lease counterpart or a tenant on a tower company site.
Site Acquisition Representative: The carrier or tower company employee or contractor responsible for securing new tower sites and managing existing lease relationships.
MD7: A third-party lease management company hired by AT&T to renegotiate ground leases downward. Not to be confused with a carrier representative - MD7 works for the carrier, against your interests.
Lease Acquisition Company: A company that purchases the right to receive future lease income in exchange for a lump-sum payment. Landmark Dividend, TowerPoint, and Atlas Tower are examples.
Key Lease Clause Terms
Initial Term: The first contractual period of the lease, typically 5 years.
Renewal Option / Renewal Term: A provision giving the carrier the right to extend the lease for an additional period (typically 5 years) at their sole discretion. Most leases have four to five renewal options.
Automatic Renewal: A renewal that occurs automatically unless either party provides notice of termination. Favors the carrier because they can extend without your active consent.
Holdover: The period during which the tenant continues occupying the property after the lease term has expired without executing a formal renewal. Holdover terms can be important leverage points.
Termination for Convenience: A lease provision allowing the carrier to terminate the lease with notice, for any reason. Property owners should push for limitations on this provision - shorter notice requirements (e.g., 30 days) are very unfavorable to landlords.
Assignment Provision: Governs the carrier's ability to transfer the lease to another party. Unrestricted assignment allows the carrier to transfer your lease to a tower company or another carrier without your consent.
Non-Disturbance Agreement: A separate agreement ensuring that a lender's foreclosure on your property does not terminate the tower lease. Required by lenders when the property is mortgaged.
Equipment Removal Obligation: A provision requiring the carrier to remove all equipment and restore the site at lease end. Critical - without this provision, you may bear the cost of tower removal.
Indemnification: A contractual obligation to protect the other party from specified liabilities. The carrier should indemnify the property owner for liabilities arising from the tower and equipment.
Industry-Specific Terms
Macro Tower / Macro Cell: A traditional full-height cell tower, typically 100-300 feet tall, serving a broad geographic area. Ground leases for macro towers are the most common type of cell tower lease.
Small Cell: A compact, low-power cellular antenna installation designed to provide coverage in a limited area. The building blocks of 5G dense networks. Mounted on buildings, poles, and streetscapes.
mmWave (Millimeter Wave): Very high-frequency 5G signals (24-100 GHz) with extremely short range. Requires dense small cell networks to provide urban coverage.
Mid-Band 5G: 5G signals in the 1-6 GHz range, offering a balance of coverage range and data speed. T-Mobile's 2.5 GHz and Verizon's C-band are mid-band 5G deployments.
REIT (Real Estate Investment Trust): A corporation that owns income-producing real estate and distributes most of its taxable income to shareholders. American Tower, Crown Castle, and SBA Communications are all REITs - their financial incentive is to maximize returns for shareholders, which means minimizing what they pay you in ground rent.
Co-location / Co-tenancy: The practice of multiple carriers sharing infrastructure on a single tower. Tower companies actively pursue co-location because it increases their revenue from the same infrastructure investment.
Backhaul: The network connection between a cell tower and the carrier's broader network. Backhaul infrastructure represents a significant investment by the carrier that increases their commitment to a specific site.
