A single lease over an entire property or block of space, under which the master tenant subleases to the actual occupants. Lenders see it as a credit substitution: the rent roll becomes one obligation from the master tenant rather than many from the occupants.
The longer version
One tenant leases the whole asset from the owner and then sublets it. The occupants sign with the master tenant, not with the owner, so the owner's income depends on one counterparty. That structure appears in credit tenant deals, in sale-leasebacks, in operator-run assets such as senior housing and hospitality, and in lease-up guarantees where a sponsor master leases vacant space to carry a loan through stabilization.
For a lender the attraction is predictability. A single lease with a strong master tenant converts a variable rent roll into a fixed obligation, which underwrites cleanly and supports a coverage test. The risk is the mirror image: all of that income now sits on one credit, and if the master tenant fails the property does not simply revert to the sublease income. What happens next depends on documents written long before.
The document that decides it is the subordination, non-disturbance and attornment agreement at the sublease level. Without it, a master lease termination can wipe out the subleases beneath it, and the lender inherits an empty building full of occupants with no contractual relationship to the owner. With it, the subtenants attorn to the owner or the lender and keep paying. Underwriting a master lease without reading the sublease SNDAs is underwriting the master tenant's balance sheet alone.
The second thing lenders test is whether the master lease is economic or cosmetic. A sponsor master lease over vacant space, posted to make a coverage test work during lease-up, is a different instrument from a credit tenant master lease on an operating asset, even though both produce one rent line. The questions are whether the master tenant has assets beyond the lease, whether the rent is at market, whether it is guaranteed, and what happens to the guarantee at stabilization.
In the closing file the master lease travels with its exhibits, the rent roll beneath it, the subleases or a sublease summary, estoppels from the master tenant and often from major subtenants, and the SNDAs. Those estoppels are where closings slip, since they require a response from a party with no deadline pressure of its own.
Common questions
- What is a master lease in commercial real estate?
- A single lease covering an entire property or a block of space, where the master tenant then subleases to the actual occupants. The owner collects one rent from one counterparty instead of many rents from many tenants.
- Why do lenders accept master leases?
- Because a single obligation from a strong master tenant underwrites more cleanly than a rent roll that turns over. It supports a coverage test and makes income predictable. The trade is concentration: the whole rent roll becomes one credit.
- What happens to subleases if the master lease terminates?
- It depends on the subordination, non-disturbance and attornment agreements at the sublease level. Without them a termination can extinguish the subleases. With them the subtenants attorn to the owner or lender and keep paying. This is the single most important document set in a master lease deal.
- What is a sponsor master lease?
- A master lease granted by the sponsor itself, usually over vacant space, to carry debt service through lease-up. It produces a rent line, but it is only as good as the sponsor's balance sheet and any guarantee behind it, which is why lenders test it differently from a credit tenant lease.
- What does a lender review in a master lease?
- Term and renewal rights against the loan term, rent against market, the master tenant's credit and guarantees, assignment and termination rights, the sublease SNDAs, and estoppels from the master tenant and significant subtenants.
