An unsubordinated ground lease is a long-term land lease in which the landowner refuses to pledge the fee title as collateral for the tenant’s financing, so the land itself sits above every mortgage, mechanics lien, and other claim the tenant creates against the property. The tenant can still build, borrow, and operate for decades, but its lender’s security is limited to the leasehold interest and the improvements on top of it. The land stays with the landowner no matter what the tenant does financially.
That priority structure is the whole point of the arrangement, and most of what follows in a well-drafted lease exists either to protect it or to give the tenant’s lender enough comfort to live underneath it.
Unsubordinated Versus Subordinated
The word only makes sense against its opposite. In a subordinated ground lease, the landowner agrees to pledge the fee interest as part of the collateral package for the tenant’s construction loan. The lender gets a mortgage covering both the land and the improvements, and if the tenant defaults, the lender can foreclose on everything, including the dirt. Landowners who subordinate take on enormous risk because their ownership now rides on a loan they had no part in negotiating.
In an unsubordinated lease, the landowner refuses. The tenant’s lender can only take a mortgage against the leasehold interest and the buildings. Institutional landowners, pension funds, and government entities overwhelmingly insist on this structure. The tradeoff is real: because the lender cannot reach the land, leasehold loans are priced as riskier, often with higher interest rates or stricter terms.
Ground leases of this kind typically run 50 to 99 years so the tenant has time to build, operate, and recoup the investment in improvements. A lender advancing $100 million for a tower on leased ground knows from day one that its security is limited to the building and the right to be there.
What Happens in Default and Foreclosure
Priority matters most when money runs out. If the tenant defaults on a leasehold mortgage, the lender’s only remedy is to foreclose on the leasehold interest and the physical improvements. The landowner’s fee title is untouched because it was never part of the security. The foreclosing lender, or whoever buys at the sale, steps into the tenant’s shoes and inherits the obligation to pay ground rent.
Here is where the hierarchy bites. If the new leasehold owner fails to pay rent, the landowner can terminate the lease entirely. Termination wipes out the leasehold and every interest attached to it, including the lender’s mortgage. The landowner gets the land back with the buildings on it, and the lender loses its collateral. That threat gives every leasehold lender a strong incentive to keep ground rent current while sorting out a troubled project.
The New Lease Requirement
Because termination is so destructive to lender collateral, most financeable ground leases include a provision requiring the landowner to offer a new lease to the leasehold lender if the original lease is terminated for any reason, on substantially the same terms. The lender can step in directly and preserve its position. Landowners generally accept the provision because it keeps rent flowing and avoids the disruption of an empty site.
Lease Language That Keeps the Landowner Senior
The senior position does not exist automatically. Specific lease language establishes it, and gaps in that language are where deals fall apart years later.
Non-Subordination Clause
The lease must state explicitly that the tenant has no authority to encumber the landowner’s fee interest with any mortgage, lien, or other claim. Without this clause, a tenant’s lender might argue that the lease implicitly allows fee encumbrances, especially in jurisdictions where statutory presumptions favor creditors.
Mechanics Lien Protections
Construction on leased ground creates a specific risk. Contractors who go unpaid can file mechanics liens, and in many jurisdictions those liens can attach to the landowner’s fee interest if the landowner is deemed to have consented to the work. The fact that a lease requires the tenant to build improvements can sometimes be enough to imply that consent. Well-drafted ground leases require the tenant to obtain lien waivers from all contractors on payment, post bonds when required, and indemnify the landowner against any liens that reach the fee. Some leases also require proof of payment at each construction milestone and identification of all contractors and subcontractors before work begins.
Recorded Memorandum of Lease
A Memorandum of Lease filed in the local land records office puts anyone searching title on notice that the fee is subject to a ground lease and that the landowner’s position is senior to any tenant financing. The memorandum summarizes the parties, property description, lease term, and the existence of the non-subordination provision, without exposing every lease term to public view. Recording prevents lenders from later claiming they were unaware of the priority structure during due diligence.
What Leasehold Lenders Demand in Return
Banks that finance on an unsubordinated lease know they are taking a junior position. They negotiate specific protections directly with the landowner, and those protections often take months to finalize.
Notice and Cure Rights
The landowner must send written notice of any tenant default directly to the leasehold lender before exercising remedies. Under Freddie Mac’s requirements, the lender gets at least 10 additional days beyond the tenant’s grace period to cure a monetary default like unpaid rent, and at least 60 additional days for a non-monetary default like a maintenance violation.1Freddie Mac Multifamily. Multifamily Seller/Servicer Guide, Chapter 30: Ground Lease Mortgages For defaults a lender cannot physically cure, such as a tenant’s personal bankruptcy filing, the lease must either prohibit termination while rent is paid or give the lender enough time to foreclose and install a new operator.
Minimum Remaining Term
Lenders need the lease to outlast the mortgage by a comfortable margin. Fannie Mae requires the unexpired lease term to exceed the loan maturity by at least five years.2Fannie Mae. B2-3-03, Special Property Eligibility and Underwriting Considerations: Leasehold Estates A lease with 30 years remaining and a loan on a 25-year amortization leaves no room if anything goes wrong, which is why ground leases with short remaining terms become difficult to finance.
No Modifications Without Lender Consent
The lease should prohibit the landowner and tenant from amending, terminating, or surrendering it without the leasehold lender’s written consent. Without that, the two parties could theoretically shorten the term or increase the rent in ways that destroy the lender’s underwriting assumptions. Lenders treat this as non-negotiable.
Estoppel Certificates
An estoppel certificate is the landowner’s written confirmation that the lease is in effect, rent is current, and no defaults exist. Leasehold lenders and prospective buyers of the tenant’s interest require one before closing any transaction. The certificate locks the landowner into the statements it contains. A standard estoppel confirms current rent, commencement and expiration dates, any options to renew or purchase, and whether either party has outstanding claims. The lease should set a deadline for delivery after a request, because some leases treat late delivery as a deemed confirmation that everything is current, which may not reflect reality.
Insurance and Condemnation Money
When a building burns or the government takes the property, the priority hierarchy decides who controls the money. These moments create tension because the landowner owns the land, the tenant built the building, and the lender financed it.
Casualty Proceeds
Freddie Mac requires the lease to prohibit termination due to casualty unless the leasehold mortgage is paid in full, and insurance proceeds must go to the leasehold lender or an independent trustee rather than the landowner, until the property is either fully restored or the mortgage is satisfied.1Freddie Mac Multifamily. Multifamily Seller/Servicer Guide, Chapter 30: Ground Lease Mortgages The lender’s collateral is the building, so the lender needs to control the rebuild or get paid off before anyone else touches the check. The landowner’s interest in the land itself is not destroyed by fire, so the fee priority remains intact regardless.
Condemnation Awards
When the government takes all or part of the property through eminent domain, it values the property as a single parcel and pays one lump sum. The landowner, tenant, and lender then divide the award according to the allocation formula in the lease. Under Freddie Mac’s standards, the leasehold lender’s share must be at least the total award minus the value of the bare land.1Freddie Mac Multifamily. Multifamily Seller/Servicer Guide, Chapter 30: Ground Lease Mortgages Without a negotiated clause, the default rule gives the tenant compensation for the bonus value of the leasehold, meaning the difference between contract rent and market rent for the remaining term, plus the value of improvements to the extent they add to the rental value of the unexpired term. Litigating this after the fact is expensive and unpredictable, and legal fees alone can consume a meaningful portion of the award.
Rent Resets
Priority protects the landowner legally. Rent resets protect the landowner economically. A ground lease that locks in flat rent for 99 years quietly transfers wealth from the landowner to the tenant as inflation erodes the real value of the payments.
The standard approach reappraises the land every 20 to 30 years and resets the annual rent to a percentage of current fair market value, typically in the 6 to 7 percent range. Between major resets, annual CPI-tied increases keep the rent roughly current with inflation, often subject to caps that limit any single adjustment. Tenants and their lenders want predictability; landowners want to capture rising land values. Capping annual CPI increases too low can leave the landowner behind over a multi-decade lease, which is why the periodic fair market value reappraisal serves as the primary correction mechanism.
What Happens at the End
The tenant builds the improvements and is generally considered their owner during the lease term. But that ownership is temporary. When the lease expires or terminates early for default, all buildings, fixtures, and infrastructure revert to the landowner without additional compensation.3The University of Texas System. Ground Leases: Basic Legal Issues The landowner gets the land back with everything on it, free of the tenant’s previous claims and liens.
This reversionary interest is one of the main reasons institutional investors favor ground leases over outright sales. A pension fund that ground-leases a prime downtown parcel keeps its ownership forever, collects rent for decades, and eventually receives a fully improved property. The unsubordinated position ensures that outcome even if the tenant’s business fails midway through the lease.
Bankruptcy on Either Side
Federal law treats ground leases as executory contracts, which means a bankrupt party can potentially reject them. The protections depend on which side files.
Tenant Bankruptcy
A bankrupt tenant has 120 days from the filing to decide whether to assume or reject the ground lease. If it does neither, the lease is deemed rejected and the tenant must surrender the property. A court can extend this deadline by an additional 90 days for cause.4Office of the Law Revision Counsel. 11 USC 365 – Executory Contracts and Unexpired Leases Rejection is not necessarily bad news for the landowner: it accelerates the reversion.
Landowner Bankruptcy
If the landowner files and rejects the lease, the tenant can either treat it as terminated and walk away, or retain its rights for the remaining term, including renewal and extension periods enforceable under state law.4Office of the Law Revision Counsel. 11 USC 365 – Executory Contracts and Unexpired Leases A tenant that stays can offset damages from the landowner’s non-performance against future rent but cannot pursue other claims against the bankruptcy estate. The definition of lessee here includes any successor, assignee, or mortgagee permitted under the lease, which means the leasehold lender’s rights survive a landowner bankruptcy as well. Without this federal protection, a landowner filing could theoretically wipe out the lease and destroy the lender’s collateral.
Tax Positions on Each Side
The structure creates distinct tax positions, and missing them can produce unexpected bills or missed deductions.
Ground rent is rental income to the landowner. Every payment received counts in gross income, including tenant payments toward the landowner’s property taxes or insurance, and lease cancellation payments are treated as rent in the year received.5Internal Revenue Service. Tips on Rental Real Estate Income, Deductions and Recordkeeping The landowner reports on Schedule E, and passive activity loss rules may limit deductible losses in a given year.
A tenant cannot depreciate the land, but a tenant that constructs permanent improvements on leased land can depreciate those improvements.6Internal Revenue Service. Publication 527, Residential Rental Property For nonresidential real property, the recovery period under the Modified Accelerated Cost Recovery System is 39 years.7Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System If the remaining lease is shorter than 39 years, the tenant still uses the 39-year period because the statute keys recovery to the property classification rather than the lease duration.
A leasehold interest counts as like-kind with a fee simple interest for a Section 1031 exchange, but only if the leasehold has 30 or more years remaining, including all renewal options.8eCFR. 26 CFR 1.1031(a)-1 – Property Held for Productive Use in Trade or Business A lease with 25 years left will not qualify, no matter how much the tenant invested in improvements.
Leases with escalating rent schedules or deferred payment structures may fall under Section 467, which requires both parties to accrue rental income and deductions on a present-value basis rather than following the cash payments.9Office of the Law Revision Counsel. 26 USC 467 – Certain Payments for the Use of Property or Services The provision applies when total rent exceeds $250,000 and at least one payment is deferred beyond the calendar year following the year of use. For long-term ground leases with built-in escalations, Section 467 almost always applies, and the constant rental accrual method can produce taxable income in years before the corresponding cash is actually received.
