The 99-year ground lease is the standard long-form land lease in New York City. It sits under the Empire State Building's 1961 recapitalization and shaped the buildout of Battery Park City. Trinity Real Estate uses it across its Hudson Square portfolio, and dedicated REITs like Safehold have built an entire public company around it. It is also widely misunderstood, including by investors who have owned NYC commercial real estate for years. This guide covers why the term is 99 years, how rent resets work over nearly a century, how leasehold and fee mortgages are sized against the term, and what happens once a 99-year lease runs into its final decades.
Why 99 years became the standard NYC ground-lease term
No single statute created the 99-year ground lease. It grew out of common-law tradition, federal tax treatment, lender practice, and a century of habit among New York's institutional landowners. English common law historically treated any lease longer than 100 years as, in effect, a conveyance of the fee, so 99 years became the practical ceiling for an instrument that still counted as a lease.
Federal tax treatment reinforced the convention. Under a 99-year lease, the leasehold owner gets depreciable improvements, a deductible ground-rent expense, and deductible interest on the leasehold mortgage. The fee owner collects ordinary ground-rent income without triggering gain recognition on the land. That last point matters most to charitable, religious, and educational landowners (Columbia, NYU, Trinity Church, the Archdiocese, Cooper Union), which hold land in perpetuity and could not sell it even if they wanted to.
Lenders like the 99-year term because it leaves room to amortize a 30-year leasehold mortgage with plenty of tail. By the late 20th century the 99-year ground lease was the New York convention, used at the Empire State Building, the Helmsley Building, large portions of Rockefeller Center's historical ownership structures, MetLife Tower, Carnegie Hall Tower, Battery Park City, and the Roosevelt Island master lease from the City of New York.
How 99-year rent resets actually work
A 99-year ground lease that never resets rent is, economically, a sale at a discount. To keep real value on the fee side over nearly a century, virtually every modern NYC 99-year ground lease includes periodic rent resets. The reset clause is the most important economic term in the lease, and the one the two sides fight over hardest.
Fair-market-value resets (the most common)
At a fair-market-value reset, ground rent moves to a set percentage of the land's then-current fair market value, typically 6%, 7%, or 8%, with the land valued as if vacant and available for its highest and best use. Appraisers perform the valuation, and disputes go to a third appraiser or to arbitration. The Empire State Building's 1991 reset under its 99-year lease, and the public dispute that followed, is the standard example of how much a single FMV reset can move.
CPI-linked resets
Some 99-year leases reset ground rent against the Consumer Price Index, either annually or at set intervals, often with floors and caps. CPI resets are predictable and modest in any one year, but they compound hard over 99 years: a 2.5% annual CPI escalator multiplies the rent more than tenfold over the full term.
Percentage-of-land-value resets
A hybrid now common in newer Manhattan ground leases sets rent at a fixed percentage of appraised land value at each reset, with CPI escalators in between. The fee gets inflation protection from the CPI piece and land-value participation from the appraisal piece. Dedicated ground-lease investors like Safehold favor this structure.
Fixed-step resets
The simplest version: ground rent steps up to pre-set dollar amounts on pre-set dates. It is predictable but exposed to inflation, and older NYC ground leases written this way have handed leasehold owners enormous windfalls when inflation outran the schedule.
Financing a 99-year leasehold position
Financing a leasehold under a 99-year ground lease is routine in New York, but it is a different loan from a fee mortgage. The lender's collateral is the leasehold estate, a wasting asset that expires at year 99. Before funding, the lender requires the fee owner to sign a non-disturbance and recognition agreement (an SNDA, in ground-lease practice) that preserves the leasehold mortgagee's rights if the leasehold tenant defaults on ground rent.
Without an SNDA, a leasehold mortgage can't be insured and is close to unfinanceable. Experienced leasehold lenders also require notice-and-cure rights, the right to step into the leasehold tenant's position, and express protection against termination by the fee owner. These mortgagee protections are the most heavily negotiated clauses in any modern NYC ground lease.
Leasehold loans typically run 10 years on CMBS and 15–25 years on life-insurance paper, with amortization sized so that at least 25–30 years of lease term remain at maturity. Once remaining term falls below roughly 40 years, the pool of willing lenders shrinks. Below 30 years, leasehold financing is scarce and expensive.
What actually happens as a 99-year lease approaches expiry
In practice, nearly every commercially significant 99-year ground lease in New York is renegotiated, extended, or restructured well before its scheduled expiry. Both sides want that outcome. The fee owner doesn't want a building handed back with stub-tail leases and deferred capex, and the leasehold owner doesn't want to hold a wasting asset no lender will finance.
What changes over time is who has the upper hand. With 50 years remaining, the leasehold has every option open. At 30 years, the conversation moves toward an extension on terms that favor the fee owner, usually a significant upfront payment, a step-up in ground rent, or both. At 15 years, the leasehold is fighting to survive. At 5 years with no extension signed, the leasehold trades at land-value salvage and the fee owner controls the negotiation.
Several well-known NYC ground leases have reached these points in living memory. The Lever House recapitalization, the Helmsley Building's ground-lease restructurings, and a series of Trinity Real Estate extensions in Hudson Square are widely studied for how late-term ground-lease negotiations actually get done.
Subordinated versus unsubordinated ground leases
One distinction in NYC ground leases that trips up even experienced buyers is whether the fee is subordinated or unsubordinated to the leasehold mortgage. In an unsubordinated structure, by far the more common form in modern Manhattan deals, the fee owner holds first position on the land and the leasehold mortgagee's lien reaches only the leasehold estate. The leasehold lender has no claim on the fee, which is why long-duration capital prefers unsubordinated structures.
In a subordinated ground lease, the fee owner agrees to put the fee interest behind the leasehold mortgage. Historically this supported larger leasehold loans, because the lender could foreclose on the land as well as the leasehold estate. It also exposed the fee owner to the real possibility that a leasehold foreclosure would wipe out the fee. Subordinated structures are rare in institutional NYC deals today, though they still turn up in older leases and some smaller commercial transactions.
The valuation difference is material. Unsubordinated fee positions trade at tight, bond-like yields because the structure protects the fee; a subordinated fee has to be priced with the wipe-out risk spelled out. Subordination status is one of the first items confirmed in any lease abstract review.
Safehold and the modern 99-year ground lease
Safehold (NYSE: SAFE), a public REIT set up to originate new ground leases under existing commercial buildings, changed how the modern NYC 99-year lease is written. Its standard form pairs a 99-year unsubordinated ground lease with a Caret participation, a residual-value instrument that keeps the leasehold counterparty in on land-value appreciation. Rent resets on a percentage-of-land-value basis, which smooths the timing of cash flow compared with the traditional 25-year FMV reset.
For a NYC building owner weighing a Safehold-style origination, the 99-year lease is as much a financing decision as a real estate one. Splitting the fee from the leasehold raises substantial capital up front, lowers ongoing income-tax exposure (ground rent is fully deductible), and leaves the owner operating a financeable leasehold. The trade-off is permanent. Once the ground lease is in place it is, for practical purposes, irreversible, and it governs ownership, financing, and exit for the life of the building.

Robert Khodadadian and Skyline Properties have brokered and advised on numerous 99-year ground-lease fee and leasehold positions across Manhattan. Commercial Observer profiled Khodadadian in a 2018 ground-lease Q&A, and he is among the brokers NYC owners and capital sources call first for confidential ground-lease fee sales, leasehold dispositions, and reset advice.
If you own a fee position heading into a 25-year FMV reset, hold a leasehold with 30–60 years remaining, or are looking at an acquisition on either side of the structure, the firm handles the brokerage, the valuation, and the capital-markets coordination for this asset class specifically. The usual first step is a confidential broker opinion of value (BOV).
Frequently asked questions
- Why exactly 99 years and not 100?
- Common law historically treated a lease longer than 100 years as a transfer of the fee, which would trigger tax and recording consequences neither the landowner nor the developer wanted. At 99 years the instrument stays a lease, while the leasehold tenant still gets what amounts to a century of economic ownership.
- Can a 99-year NYC ground lease be terminated early?
- Only on tenant default, and even then the leasehold-mortgagee protections (SNDAs) usually give the leasehold lender extensive notice-and-cure rights and the right to step into the leasehold position. A 99-year ground lease is built to be uncancellable for its full term unless there is a material economic breach.
- How much does ground rent typically reset to?
- At a fair-market-value reset, ground rent commonly resets to 6–8% of appraised land value, with the land valued as if vacant at its highest and best use. The number that moves the result most is the appraised land value itself, which is why FMV resets on trophy NYC ground-lease properties are so heavily litigated.
- Can I get a CMBS loan on a 99-year leasehold?
- Yes, if the lease has more than ~30 years of remaining term at loan maturity, includes standard leasehold-mortgagee protections, and the fee owner signs a non-disturbance and recognition agreement. Life-insurance lenders also actively quote leasehold loans on 99-year structures with strong reset mechanics.
- Are 99-year ground leases more or less risky than fee ownership?
- They carry a different kind of risk, so neither answer is strictly right. The leasehold takes on ground-rent reset risk and reversion risk; the fee takes on land-value depreciation risk and the credit risk of the leasehold tenant. Return relative to risk depends on the specific lease terms, the remaining term, and the going-in basis.
