Airport Ground Lease Financing: Lending Against a Leasehold
Most airport real estate cannot be bought. The land is publicly owned and federally obligated, so operators lease it and finance the improvements they build on it. That makes the ground lease, not a deed, the foundation of the loan, and it is the reason airport deals confuse lenders who are used to owning the dirt as collateral.
You Are Financing a Leasehold, Not the Land
A leasehold mortgage secures the tenant's rights under the lease plus the improvements, not the underlying fee. If the lease ends or is terminated, the collateral can effectively evaporate. That is why lenders scrutinize the lease document itself as closely as the building, because the lease is what they are actually lending against.
Why Remaining Term Governs Loan Length
Lenders want the lease to extend well beyond loan maturity, often ten or more years past the final payment, so the collateral outlives the debt with room to spare. A fifteen-year loan against a lease with eighteen years left is a hard sell. Renewal options help only if they are firm and assignable, not left to the sponsor's discretion at renewal time.
Leasehold Mortgagee Protections
A financeable lease includes lender protections: notice and a right to cure the tenant's defaults, the right to assign or foreclose the leasehold, and formal recognition of the lender by the airport sponsor. Leases drafted without these are effectively unfinanceable until they are amended. These protections are negotiated with the airport sponsor, not with the seller.
FAA Grant Assurances in the Background
Federally obligated airports operate under grant assurances that shape what a sponsor can and cannot agree to, including minimum standards and through-the-fence policies. Those constraints explain why airport ground leases look different from ordinary commercial ground leases, and why a sponsor sometimes cannot simply grant a term or a provision a lender wants.
