Sublease strategy splits in two: as a sublessee, capture 20–40% rent discount in exchange for shorter term and higher counterparty risk; as a sublessor, professionalise the offer to clear quickly without subsidising a competitor.
Sublease prices typically 20–40% below direct asks for equivalent spec.
Term-take risk and limited TI are the biggest sublease tradeoffs.
Landlord consent is required — negotiate consent timelines and profit-split.
For over-sized incumbents, sublease usually beats holding empty.
Trophy submarkets clear sublease fast; established submarkets do not.
Consider a recapture (give the space back to the landlord) before subletting.

What this is
Sublease strategy is the structured approach to either taking a sublease (as a tenant capturing rent discount) or offering a sublease (as an over-sized incumbent offloading excess space). Since 2020, sublease overhang has been a defining feature of every Tier 1 market — concentrated in established and value tier Class A and Class B stock, much thinner in trophy and prime tier. As a sublessee, the discount can be substantial; as a sublessor, the structural reality is that you are competing against your own landlord's direct stock and need to professionalise the offer.
Sublease economics
Sublease space typically prices 20–40% below direct asks for equivalent spec, with the discount concentrated in shorter-term, lower-spec, or sub-floor deals. The sublessor's economics: any rent collected reduces the loss on the over-leased footprint. The sublessee's economics: lower face rent, but limited TI (often zero), 'as-is' condition, shorter term, and reliance on the prime tenant's covenant.
The three structural risks for the sublessee
(1) Prime tenant default — if the sublessor defaults on the head lease, you can lose your sublease unless you have a non-disturbance agreement with the landlord. Always negotiate a non-disturbance with the landlord (the landlord usually accommodates if the sublessee is institutional). (2) Limited TI — typically zero, sometimes the sublessor offers a partial allowance. (3) Term-take risk — sublease terms run only to the end of the head lease, often 3–5 years; after that, you negotiate fresh with the landlord (typically at full direct rent).
Landlord consent
Standard Class A leases require landlord consent to sublease, 'not to be unreasonably withheld'. The consent process typically takes 30–60 days; negotiate explicit consent timelines (15–30 business days, deemed-consent if missed) in the head lease. Profit-split mechanics (typically 50/50 above pass-through) apply on subleases above the head-rent level — though in current markets, sublease rents are below head-rent, so profit-split rarely activates.
Recapture: a faster exit
Many Class A leases include a recapture clause — the landlord can take the sublease space back rather than consent to the sublease. From the over-sized incumbent's perspective, recapture is often the cleaner exit: the landlord assumes the space, the incumbent reduces the footprint, and the lease economics adjust. Recapture is faster and operationally simpler than running a sublease marketing campaign.
If your lease has recapture, request it before going to market with a sublease — landlords often prefer recapture when it lets them re-let at higher direct rents.
Marketing a sublease
If you are subletting, professionalise the offer. Engage a sublease-specialist broker (different skill set from new-build leasing); produce a clean marketing pack (photography, plans, offer terms); offer turn-key spec (existing furniture, AV, IT) to differentiate from raw sublease space; and price 25–40% below direct asks to clear quickly.
Do not price at parity with the landlord's direct rents — you will not win. The sublease market clears on discount.
Sublease velocity by submarket tier
Trophy submarkets (Hudson Yards, Mayfair, Marina Bay) clear sublease fast — typically 4–8 weeks from listing to LOI. Prime submarkets clear in 8–16 weeks. Established and value submarkets clear in 16–40 weeks or not at all. If you are sublessor in an established submarket, plan for an extended marketing window or pivot to recapture.
Sublease-specific lease drafting
The sublease is a separate contract referencing the head lease. Critical drafting items: (1) explicit non-disturbance agreement with the landlord, (2) opt-out if head lease is terminated, (3) defined sublessor obligations (delivery condition, snagging, hand-over schedule), (4) clear allocation of opex/service charge pass-throughs, (5) explicit access rights and signage rights.
Decision aid
If you are taking a sublease: target trophy/prime tier where discount is genuine and clearance is fast; insist on a non-disturbance agreement with the landlord; treat term-take risk as the real cost. If you are offering a sublease: check for recapture first, then price 25–40% below direct asks, professionalise the marketing, and offer turn-key spec.
Frequently asked questions
How much discount can I get on a sublease?
Typically 20–40% below direct asks for equivalent spec.
What's the biggest sublease risk?
Prime tenant default — always negotiate a non-disturbance agreement with the landlord.
Should I sublease or recapture?
If your lease has recapture, request it first — recapture is often the cleaner exit and the landlord may prefer it.
How long does sublease take to clear?
Trophy: 4–8 weeks. Prime: 8–16 weeks. Established: 16–40 weeks or not at all.
Do I need landlord consent?
Yes — standard Class A leases require landlord consent, not to be unreasonably withheld.
