Ground-Lease Reversion Risk: Why a Hangar Can Be Worth Less Than It Cost to Build

Very few hangars sit on land the owner holds in fee. The typical structure is a ground lease: the airport sponsor owns the land, the tenant builds and owns the hangar, and at the end of the lease term the improvements revert to the sponsor. That reversion clause is the single most important number in the valuation, and it is the one that industrial-property methods routinely get wrong.

Leasehold is not fee simple

When an appraiser or a buyer treats a hangar as if it were a freestanding warehouse, they value a perpetual asset. A leasehold hangar is not perpetual. The owner controls the building only for the years remaining on the lease, after which the value transfers to the sponsor for little or no compensation. The correct question is not what the hangar would cost to replace. It is how much income the building can produce over the years the tenant actually controls it.

Why remaining term drives the number

Value in a leasehold is the present worth of the income stream over the remaining term, plus any reversion the tenant is entitled to receive, which is often zero. A hangar with fifteen years left is worth materially less than the same hangar with forty years left, even though the steel is identical. As the term shortens, the amortization window compresses, each remaining year carries more of the load, and the value curve bends down well before the lease actually expires.

Financing follows the term

Lenders understand this even when buyers do not. A prudent lender wants the ground-lease term to extend well beyond the loan amortization, with a cushion, because the collateral evaporates at reversion. When remaining term and loan term converge, credit gets expensive or disappears. That financing constraint feeds back into value, because a building that cannot be financed trades at a discount to one that can.

Renewal is an assumption, not a fact

Owners often assume the sponsor will extend. On a federally obligated airport, the sponsor operates under grant assurances and revenue-use rules that constrain what it can offer and at what rent. An extension may come at a reset rent that changes the economics entirely. Treating renewal as automatic, or as free, is the most common way a leasehold hangar gets overvalued.

How to analyze it

Model the income over the remaining term explicitly, set the reversion to the tenant at its contractual value rather than at market, and test the sensitivity of value to term length and to a rent reset at renewal. The output usually surprises owners who have been carrying the asset at replacement cost.
