Is sublease space cheap in Seoul?

Sublease typically trades 15–30% below direct asks for equivalent specification. The total economics depend on remaining term, TI condition, and the assignment/sublet provisions in the prime lease.

Can I convert a sublease to a direct lease in Seoul?

Sometimes. On longer-horizon takes, ask the landlord to write a fresh direct lease at sublease commencement — they get a creditworthy long-term tenant; you get rent-free and TI.

What you give up

Subleases trade at a discount, but you inherit the prime tenant's term, get limited or no TI, and live with whatever fit-out">fit-out exists. For occupiers under a 24-month horizon, that tradeoff usually wins. For multi-year HQs, direct deals with rent-free and TI almost always produce better effective economics.

Negotiating points

Look for direct deals with the landlord at sublease commencement (a "bypass" structure) — landlords will sometimes write a fresh long-term lease to take a problem space off the prime tenant's books. Standard 5-year lease (often 3+2). Rent + management fees billed separately. Large jeonse (lease deposit) common — 10-20x monthly rent. Reinstatement contractual.
