A lease divides a property into two separate interests: the leased fee interest, which the landlord keeps, and the leasehold interest, which the tenant holds. The landlord still owns the real estate but has handed over possession for the lease term in exchange for rent and the right to get the property back when the lease ends. The tenant doesn’t own anything tangible, but holds a contractual right to occupy and use the space, and that right can itself be valuable, financeable, and transferable. Understanding the leased fee interest vs the leasehold interest matters any time money, taxes, financing, foreclosure, or a government taking enters the picture.
What the Landlord Keeps: The Leased Fee Interest
The leased fee interest is what the property owner retains after signing a lease. Two components make it up. First, the right to collect rent for the duration of the lease. Second, the reversionary right to regain full possession when the lease expires.
Its value is the sum of those two pieces. The rent stream is worth the present value of future payments discounted at an appropriate rate. The reversion is worth the projected value of the property at lease expiration, also discounted back to today. Together, those two figures capture the economic value of the landlord’s position.
Lease terms shape the number dramatically. A landlord locked into rent set well below today’s market collects less income for years, even though the property eventually comes back. A lease with above-market rent inflates the income stream but creates risk that the tenant will struggle to pay. Tenant credit matters here too. A publicly traded retailer with strong financials reduces the risk of missed payments and supports a lower capitalization rate, which raises the present value of the income.
Who pays the operating costs matters as well. In a gross lease, the landlord covers property taxes, insurance, and maintenance out of the rent collected. Under a net lease, some or all of those costs shift to the tenant. In a triple net lease, the tenant pays property taxes, liability insurance, and maintenance directly, leaving the landlord with a cleaner income stream and far fewer management responsibilities. That cost pass-through is one reason triple net properties attract institutional investors looking for bond-like cash flows backed by physical assets.
What the Tenant Holds: The Leasehold Interest
The leasehold interest is the tenant’s right to occupy and use the property for the lease term. It is a possessory right, not an ownership right. The tenant doesn’t own the building or the land under it. What they own is the contractual right to be there, use the space, and operate without interference from the landlord as long as the lease is in effect.
That protection against interference is the implied covenant of quiet enjoyment, which exists in virtually every lease. The landlord cannot enter without proper notice, cannot disrupt the tenant’s business operations, and cannot act to force the tenant out. In exchange, the tenant has to meet lease obligations: paying rent on time, maintaining the space, and complying with use restrictions. A material breach can lead to eviction and the loss of the leasehold entirely.
In commercial real estate, a leasehold interest is often a marketable asset. Most commercial leases let the tenant assign the lease to a new party or sublease part of the space, though landlords typically require consent and will evaluate the proposed assignee’s financial strength. When a tenant subleases, the primary lease with the landlord stays intact and a new, subordinate agreement is created with the subtenant. If market rents have risen since the original lease was signed, the spread between what the tenant pays and what the subtenant pays is pure profit.
Tenants also commonly invest in build-outs to make the space usable. Those improvements typically become the landlord’s property when the lease ends, unless the lease specifically says otherwise.
When the Lease Rent Doesn’t Match the Market
A leasehold interest has measurable economic value only when the contract rent is lower than current market rent. If a tenant signed a 15-year lease at $20 per square foot and comparable space now rents for $35, the tenant holds a positive leasehold interest. They could sublease at market rates and pocket the $15 difference, or sell the lease assignment to a buyer willing to pay for that built-in discount. The value of that positive leasehold is the present value of the rent savings over the remaining lease term.
The reverse is sometimes called a negative leasehold. If contract rent exceeds market rent, the tenant is overpaying for what the space is currently worth. There is no asset to sell. No rational buyer will pay for the privilege of above-market rent, so the leasehold interest has no transferable value. The tenant’s realistic options are to negotiate a rent reduction, sublease at a loss, or wait the lease out.
One counterintuitive consequence of the split: the two interests don’t always add up to the value of the whole. If contract rent equals market rent, the combined value of the leased fee and leasehold approximates the unencumbered fee simple value. When lease terms diverge significantly from the market, the sum of the parts can fall short. Buyers see more risk in a property burdened by off-market leases, and that perception compresses what they’ll pay. A property leased at half the market rate doesn’t just shift value from landlord to tenant; it can reduce the total value the market assigns to the property.
When the lease expires, the split ends. The leasehold ceases to exist, and all rights automatically flow back to the landlord. No transfer is needed. The reversion reconstitutes the full fee simple estate, and the owner can re-lease, sell, or occupy the property without restriction.
Ground Leases: The Most Extreme Version of the Split
The distinction between the two interests is sharpest in a ground lease, where a landowner leases bare land to a tenant who constructs and owns the improvements. Ground lease terms typically run 20 to 99 years, long enough for the tenant to build, operate, and recoup their investment.
The economics are unusual. The tenant builds and owns a structure worth millions of dollars on land they don’t own. The landlord collects ground rent and watches the reversionary interest grow as improvements age and the lease ticks closer to expiration. At the end of the term, the improvements revert to the landowner along with full possession. That reversion can represent enormous value, which is why ground lease landlords sometimes accept below-market ground rent in exchange for eventually owning the building.
To protect the landlord’s income over decades, ground leases almost always include rent escalation clauses. The three common structures are fixed percentage increases at set intervals, adjustments tied to the Consumer Price Index, and periodic resets to fair market ground rent based on a reappraisal. A lease that starts at reasonable ground rent but lacks any escalation mechanism can look generous to the tenant within a decade and deeply unfavorable to the landlord within two.
Federal tax law accommodates this structure. When improvements built by a tenant revert to the landlord at lease expiration, the value of those improvements is excluded from the landlord’s gross income, provided the improvements don’t represent a substitute for rent.1Office of the Law Revision Counsel. 26 USC 109 – Improvements by Lessee on Lessor’s Property Without this exclusion, ground lease landlords would face a significant tax hit the moment a building reverted to them.
Using Either Interest as Loan Collateral
Both interests can secure loans, but lenders treat them differently.
Financing a leased fee interest is relatively straightforward. The landlord owns the underlying real estate, and the loan is secured by a conventional lien on the property. The lender’s risk analysis focuses on the factors any investor would examine: tenant credit, lease duration, and rent relative to market.
Financing a leasehold interest is more complicated because the borrower doesn’t own the land. The lender’s collateral is limited to the tenant’s rights under the lease and any improvements. Fannie Mae, which sets standards most residential lenders follow, requires that a leasehold mortgage be secured by a first lien on the property improvements and the borrower’s rights in the leasehold interest.2Fannie Mae. Special Property Eligibility and Underwriting Considerations – Leasehold Estates
Several additional safeguards usually apply. The lease term must extend at least five years beyond the loan’s maturity date, so the collateral doesn’t evaporate before the debt is repaid. The lease cannot let the landlord terminate for default without first giving the lender at least 30 days’ notice and the opportunity to cure or step into the tenant’s shoes. For leases entered into on or after September 2025, Fannie Mae also requires that the fee estate not be encumbered by prior liens unless those lienholders have agreed to recognize and not disturb the lease.2Fannie Mae. Special Property Eligibility and Underwriting Considerations – Leasehold Estates
Every one of these protections exists to address the same nightmare scenario: the lease gets terminated, the leasehold disappears, and the collateral backing the loan vanishes with it.
What Happens if the Landlord Is Foreclosed On
When a landlord defaults on their own mortgage, the tenant’s leasehold interest can be at risk. If the lender forecloses and takes ownership, the new owner may not be bound by the existing lease. Whether the tenant can stay depends on the priority of the lease relative to the mortgage under state recording law. Commercial tenants have fewer statutory protections than residential tenants in this situation, which makes private agreements critical.
The standard protective tool is a Subordination, Non-Disturbance, and Attornment agreement, or SNDA. It’s a three-party contract among the landlord, the lender, and the tenant, and each component does distinct work:
- Subordination means the tenant agrees that the lender’s mortgage takes priority over the lease. Without this, the lender’s ability to foreclose cleanly could be complicated by the tenant’s prior interest.
- Non-disturbance is the tenant’s core protection. In exchange for subordinating, the tenant gets the lender’s promise not to terminate the lease if foreclosure occurs, so the tenant can stay in the space even after the landlord loses the property.
- Attornment means the tenant agrees to recognize the new owner as landlord and keep performing under the lease, which gives the foreclosing lender or subsequent buyer confidence that rental income will keep flowing.
Experienced commercial tenants negotiate an SNDA before signing the lease, or as a condition of any lease amendment. Without one, a subordinate lease is potentially terminable in foreclosure. That matters most for tenants who have invested heavily in build-outs or whose business depends on a specific location.
How a Condemnation Award Gets Divided
When the government takes a leased property through eminent domain, the Fifth Amendment requires just compensation.3Department of Justice. History of the Federal Use of Eminent Domain But that compensation is paid once for the property as a whole, not separately to each interest holder. The government pays the fair market value as if the property were an unencumbered fee simple, and the landlord and tenant then divide that single award.
Many commercial leases include a condemnation clause specifying how the award is split. Where the lease is silent, both parties have constitutionally protected interests entitled to a share. Under the default rule in most jurisdictions, the tenant’s share is the bonus value: the present value of the difference between market rent and contract rent over the remaining lease term. If a tenant is paying $15 per square foot on a lease with eight years left, and comparable space rents for $30, that $15 savings, discounted over eight years, represents the tenant’s claim. The landlord receives the remainder.
Where the tenant has built permanent improvements, allocation gets more complex. The tenant is generally entitled to the value those improvements add to the rental value of the unexpired lease term, while the landlord receives the value they contribute to the reversionary interest. Because of that complexity, the practical move is to negotiate the condemnation clause during lease drafting rather than litigate the split after the government has filed its taking.
How Each Side Is Taxed
The two interests carry different tax treatment that mirrors their different economic positions.
The Landlord
The landlord reports rental income and claims depreciation deductions against the property’s improvements using IRS Form 4562.4Internal Revenue Service. 2025 Instructions for Form 4562 A tenant’s occupancy doesn’t change the landlord’s ownership of the building, so standard depreciation schedules keep applying. When a ground lease or long-term lease expires and tenant-built improvements revert to the landlord, the value of those improvements is excluded from gross income under federal tax law, unless the improvements were effectively a substitute for rent.1Office of the Law Revision Counsel. 26 USC 109 – Improvements by Lessee on Lessor’s Property
The Tenant
Interior improvements to nonresidential property placed in service after 2017 generally qualify as qualified improvement property with a 15-year depreciation period, provided they don’t enlarge the building, add elevators or escalators, or modify the internal structural framework.5Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System When a tenant pays a premium to acquire an existing lease from another tenant, the acquisition cost is amortized under separate rules that factor in the remaining lease term and any renewal options.6Office of the Law Revision Counsel. 26 USC 178 – Amortization of Cost of Acquiring a Lease If less than 75 percent of the acquisition cost is attributable to the remaining lease term, all renewal options are included when calculating the amortization period.
What Each Side Is Really Buying
Investors on each side are looking for fundamentally different things. Leased fee investors want predictable, long-term cash flows. They evaluate deals by looking at tenant credit, remaining lease duration, and the spread between the cap rate and their cost of capital. A single-tenant net lease to an investment-grade retailer with 20 years remaining is, in many ways, closer to a corporate bond than a traditional real estate investment. The property is the collateral.
Leasehold investors play a different game. They look for below-market leases where they can capture the spread through subleasing, or for locations where they can generate business value well in excess of their rent. A restaurant operator who secures a favorable long-term lease in a rapidly appreciating neighborhood holds a leasehold that grows more valuable every year. That interest is real, transferable, and in some cases worth more than the improvements inside the space.
Each side carries risks the other doesn’t. The leased fee investor’s biggest exposure is tenant default. If the tenant goes bankrupt or abandons the lease, the guaranteed income stream disappears and the landlord has to re-lease in whatever market exists at the time. The leasehold investor’s biggest exposure is lease expiration or termination. All the value built up, from tenant improvements to customer goodwill tied to the location, can evaporate when the lease ends and the landlord reclaims full possession.
