What does underletting mean?
Underletting is the practice of leasing property for less than the rent specified in the principal lease, usually with the landlord's consent. In this use, the person granting the lease is the landlord or current lessor, and the arrangement prevents the original lessee from having to find a replacement tenant at a higher rent. The word can also refer more broadly to granting a lease beneath an existing lease. It is related to subletting but is not always exactly synonymous: subletting typically describes a tenant transferring some or all of their tenancy to another person, whereas underletting emphasizes the reduced rent or the landlord's subordinate grant. Underletting is chiefly a formal legal and property-management term, more familiar in British usage than in ordinary American English. Because it identifies both a specific rent arrangement and a legal relationship, it is useful in leases, rent reviews, and discussions of landlord and tenant rights.
nounThe act of letting property to another tenant, especially at a rent lower than that specified in an existing lease. It may also refer more generally to granting a lease beneath an existing one.
- Leasing property to another tenant at a rent lower than that specified in the principal lease.
- Granting a lease beneath an existing lease.
"The landlord obtained written consent before underletting the apartment at a lower monthly rent."
"The landlord secured written consent before underletting the property at a reduced rate."
"The policy prohibits underletting during the fixed term without the freeholder's consent."
The plural is grammatical but rare; the activity is often expressed without a plural marker.
"Several underlettings required separate landlord approvals."
Underletting is subletting with a price tag: the defining issue is who bears the rent gap.

Where does underletting come from?
The word is formed from under and let. Let descends from Old English and developed the rental sense “lease out” by the Middle English period; under- indicates that the new letting is made beneath an existing lease or at a rate below the principal one. Sublet and underlease show the same compound pattern, although they emphasize transfer or subordinate tenure rather than specifically a reduced rent.
