What Is a Ground Lease?
A ground lease is a long-term lease of land in which the tenant—called the ground lessee—is granted the right to use and improve the land over an extended period, typically 50 to 99 years. The tenant constructs and owns the improvements (buildings, infrastructure) during the lease term. The landowner—the ground lessor—retains fee simple title to the land throughout.
At lease expiration, ownership of the improvements generally reverts to the landowner, though the specific terms depend on the lease agreement. Ground leases create a structural separation between land ownership and building ownership that has significant implications for valuation, financing, and investment strategy.
Fee Simple vs. Leasehold Interests
In a conventional real estate ownership structure, the owner holds the fee simple interest—absolute ownership of both land and improvements. In a ground lease structure, two distinct interests exist:
- Fee interest (ground lessor's position): The landowner holds title to the land and a right to receive ground rent. The fee interest benefits from land appreciation over the lease term and reversionary rights to the improvements at expiration.
- Leasehold interest (ground lessee's position): The tenant holds the right to occupy and use the land for the lease term. The leasehold interest can be sold, mortgaged, and assigned (subject to lease restrictions), but it has a finite life tied to the lease term.
Investors and lenders treat these interests differently. Fee interests are valued on their ground rent income and reversionary rights. Leasehold interests are valued on the income generated by the improvements, discounted for the risk of lease expiration.
Ground Rent Structure
Ground rent—the rent paid by the tenant to the landowner for use of the land—is the core economic term in a ground lease. Key structural elements include:
Initial rent: Set at lease inception based on the land's market value and an expected return on the landowner's capital. Common approaches include a percentage of land value (often 6–8%) or a market-negotiated flat rate.
Rent adjustments: Ground leases include periodic rent reset provisions to prevent the ground rent from falling below market as land values rise. Resets may occur every 5, 10, or 20 years and are typically tied to appraisal, CPI, or negotiated fixed escalations. Reset provisions are a major point of negotiation and a primary source of complexity in ground lease financing.
Subordinated vs. unsubordinated: In a subordinated ground lease, the landowner allows their fee interest to be subordinated to the tenant's leasehold mortgage, giving the lender security in both the leasehold and the fee. This is relatively rare. In the more common unsubordinated structure, the landowner's interest is not at risk if the lessee defaults on their leasehold mortgage.
Financing Complexity
Ground lease financing is more complex than conventional fee simple financing for several reasons:
Lender requirements: Lenders financing leasehold improvements typically require the ground lease to contain "mortgagee protection provisions"—clauses giving the lender notice of any default by the tenant, the right to cure defaults on the tenant's behalf, and the right to receive a new lease from the landowner if the leasehold is foreclosed. Without these protections, institutional lenders generally decline to finance leasehold interests.
Lease term adequacy: Most lenders require remaining lease term (including renewal options exercisable by the lessee) to exceed the loan term by a margin—typically 10–20 years. A 30-year loan requires at least 40–50 years of remaining lease term. As remaining term decreases toward expiration, financing availability narrows and costs rise.
Reversion risk: As the lease approaches expiration, the value of the leasehold interest declines toward zero regardless of building quality, since the improvements will revert to the landowner. This creates a declining value profile that affects loan amortization, refinancing, and exit strategies.
For loan-to-cost analysis on a leasehold development, lenders include the present value of ground rent obligations as a project cost, which affects the total cost base and the residual equity available to the developer.
Who Uses Ground Leases
Ground leases are common in several specific contexts:
Urban land-constrained markets: In cities like Honolulu, New York, and London, institutional landowners (universities, religious organizations, public agencies, trusts) hold land that has been in family or institutional ownership for generations. Rather than sell, these owners ground lease to developers who build on the land.
Airport and government land: Airports, military bases, and public agencies frequently use ground leases to allow private development on public land without transferring ownership. Commercial development adjacent to airports and on public sites is often structured as ground leases.
Retail and net lease properties: Major retailers and quick-service restaurant operators frequently ground lease land for their stores, particularly when fee ownership is unavailable or uneconomic. These are typically shorter-term ground leases (20–40 years) compared to institutional ground leases.
Build-to-suit developments: Some build-to-suit transactions use a ground lease structure where the land is controlled through a long-term lease rather than purchased outright, reducing upfront capital requirements.
Common Misconceptions
Ground leases always benefit the landowner. The tenant in a ground lease has the use and economic benefit of the improvements for a potentially very long period. If land values stagnate or decline, the tenant has secured use of the location at a fixed or slowly escalating rate, which may prove advantageous. Conversely, if land values rise sharply, periodic rent resets can significantly increase tenant costs.
Leasehold interests are difficult to sell. While leasehold interests are less liquid than fee simple interests, they transact regularly in markets where ground leases are common. Institutional buyers, REITs, and specialized investors actively acquire well-structured leasehold positions.
Ground leases eliminate land carrying costs. While the tenant avoids a land purchase, ground rent is an ongoing obligation that functions as a form of financing. The present value of future ground rent obligations is the economic equivalent of land debt and should be modeled accordingly.
