Ground Leases Explained: What You Actually Own When the Land Isn't Included

Most home and commercial building buyers assume they are purchasing the land along with the structure on it. But in certain markets, particularly parts of New York City, Hawaii, Washington D.C., and select college towns and downtown business districts, ownership is split. A landowner retains the underlying parcel and leases it, typically for decades, to a separate party who owns the building and any improvements. This arrangement is called a ground lease, and understanding it matters because it changes financing, resale, and long-term cost in ways that differ sharply from fee simple ownership, where a buyer owns both land and structure outright.

How a Ground Lease Works

Under a ground lease, the landowner, sometimes called the fee owner or ground lessor, grants a tenant, the ground lessee, the right to build, occupy, and use a parcel of land for a fixed period, often 50, 75, or 99 years. The tenant typically finances and constructs the building or buys an existing structure that sits on leased land, then pays ground rent to the landowner on a monthly, quarterly, or annual basis. The building itself may be sold, mortgaged, or sublet by the tenant during the lease term, but ownership of the land never transfers. At the end of the lease, unless it is renewed or the tenant exercises a purchase option, the land and everything attached to it generally reverts to the landowner, a mechanism known as reversion.

Why Ground Leases Exist

Ground leases let landowners, including institutions, family estates, religious organizations, municipalities, and universities, retain long-term control and income from valuable land without selling it outright. For developers and buyers, a ground lease can lower the upfront cost of a project or purchase because the price of the land itself is not part of the transaction, only the leasehold interest in the building. This structure appears in condominium buildings, shopping centers, office towers, and even some single-family developments, and it is common in real estate investment trust portfolios that hold long-term leasehold interests in commercial properties.

The Rent Reset Problem

The most consequential feature of many ground leases is the rent reset clause. Ground rent is frequently fixed for an initial period, then recalculated at set intervals, commonly every 10, 20, or 25 years, based on a reappraisal of the land's current market value. Because land values can rise substantially over decades, a reset can produce a large jump in ground rent, sometimes multiplying the previous payment several times over. This has generated disputes and litigation in cities where older ground leases are approaching reset dates, and it is a primary reason lenders and appraisers scrutinize these leases closely before extending credit on a leasehold property.

Financing Challenges

Lenders view leasehold mortgages differently from fee simple mortgages because their collateral, the building, sits on land they do not control. Key underwriting concerns include whether the remaining lease term extends well beyond the loan's amortization period, whether the lease is subordinated or unsubordinated to the mortgage, and whether the lease contains automatic renewal rights or a fixed expiration with no extension option. Government-backed mortgage programs and conventional lenders often require a minimum remaining lease term, and some will not lend at all on leaseholds with short remaining terms or unfavorable reset language. Buyers considering a leasehold property should ask their lender early in the process whether the specific lease is financeable, since not all leasehold interests qualify for standard mortgage products.

What Buyers Should Check Before Signing

• Remaining lease term and whether it exceeds the length of any mortgage being used to finance the purchase
• The rent reset formula, including how often resets occur, what appraisal methodology applies, and whether there are caps or collars limiting the size of an increase
• Whether the tenant has a right of first refusal or option to purchase the land if the owner ever decides to sell the fee interest
• Subordination status of the lease, since a subordinated ground lease can affect what happens to the leasehold interest if the ground lessor defaults on their own obligations
• Reversion terms describing what happens to the building and any improvements when the lease ends, and whether compensation is owed to the tenant at that point
• Property tax responsibility, since in many ground leases the tenant, not the landowner, is responsible for real estate taxes on the improved value

Why This Matters for Retail Investors

Ground leases are not limited to individual home buyers. Some publicly traded real estate investment trusts hold ground lease positions as a source of long-duration, relatively stable income, since ground rent payments are contractual obligations similar in some respects to a bond coupon. Investors researching REITs or real estate-related securities should check company filings with the U.S. Securities and Exchange Commission for disclosure on ground lease exposure, remaining lease terms, and reset schedules, since these can materially affect projected cash flows over a holding period.

For anyone evaluating a specific property, whether a condominium unit, a retail pad site, or an office building, the ground lease document itself, not the marketing materials, is the definitive source of the rent structure, renewal rights, and reversion terms. Reviewing that document with a qualified real estate attorney before signing a purchase agreement is the only reliable way to understand what is actually being bought.
