Renew or Relocate? The NYC Office Math Nobody Actually Runs
Somewhere in the last year of every office lease, a decision gets made badly. Either the tenant auto-renews on the landlord's first offer because moving sounds exhausting, or they move because a listing looked cheaper, without pricing what moving actually costs. Both mistakes come from the same source: nobody runs the full math. The renewal is a negotiation, not paperwork; your leverage is the landlord's cost of losing you; and the only honest comparison is side-by-side effective cost including every one-time expense \u2014 not asking rent versus asking rent. Here is the whole calculation, and the twelve-to-eighteen-month timeline that makes it work.

Renewal leverage is a function of time: eighteen months out you have alternatives and your landlord knows it; six months out you are a captive audience and the pricing shows it. Calendar the decision two years before expiry, run the market check at eighteen months, and let the landlord see genuine optionality, the single cheapest negotiating tactic in real estate.
Pricing the stay against the move
Renewals skip the buildout, the move cost and the disruption, worth roughly $70 to $180 per square foot in avoided one-time spend, and landlords price that convenience into weaker concessions. Relocation resets everything: fresh TI allowance, fresh free rent, a floor sized to today's headcount rather than five years ago's, at the cost of the move itself.
- Renewal wins when: the space still fits within 15%, the building behaves, and the renewal ask lands within a few dollars of market
- Relocation wins when: headcount moved materially, the market moved in your favor, or the landlord prices captivity
The book's published rents, $43 to $200, median $75, make the market check a desk exercise; that is precisely what this site's numbers are for.
Negotiating the renewal like a new deal
Renewal drafts arrive thin: same terms, new rent, sign here. Treat it as a full negotiation instead, free months on the new term, refresh allowance for carpet-and-paint at minimum, escalation reset, expansion or contraction rights matched to the new plan. Landlords concede more at renewal than tenants ask for, because the alternative on their side is vacancy plus a marketing cycle plus a new tenant's buildout.
The credible alternative is what unlocks it: tour twice, hold a real term sheet, and let it be known. We run that parallel process routinely, quiet market check, live alternative, renewal signed on corrected terms, and the tours pay for themselves in the counter.
If the answer is move
Work the quarter-length pipeline backwards from expiry: search three weeks, lease four, buildout ten to sixteen custom or two to four prebuilt, plus a safety month against the restoration handback. Watch your own restoration clause early, pricing it at month one beats discovering it at month eleven, and stage the move over a weekend with the old floor's last week as overlap.
The live floors on this site, with rents published, are the fastest possible market check for either branch of this decision. Send expiry date and headcount, and both branches come back priced.
The hidden third option: renegotiate in place
Between renewing as offered and moving entirely sits the option most tenants never exercise: restructuring the existing lease mid-term. Landlords facing a soft market, a maturing loan, or a building refinance often trade today's certainty for tomorrow's rent, a blend-and-extend that lowers the current rate in exchange for added years, a refreshed allowance against a longer commitment, or contraction rights sold back at a price.
The mechanics favor prepared tenants: know your lease's expiry leverage, know the building's vacancy picture, and arrive with the market check already run, the published rents on this site make that a desk exercise. A landlord who believes you can leave negotiates the restructure like a renewal; one who believes you are captive does not negotiate at all.
When it works, blend-and-extend beats both alternatives: better economics than the offered renewal, none of the move's cost and disruption. When it fails, you have lost two weeks and learned exactly how the renewal negotiation will go, intelligence worth having either way. We run the approach quietly, no formal process, one conversation between principals, and the answer arrives fast.
What your landlord loses if you leave
Start on their side of the table, because that's where your leverage lives. When a tenant walks, the landlord eats months of vacancy at full carrying cost, then pays for a buildout or refresh to attract the replacement, then pays leasing commissions, then typically gives the new tenant free rent to close. Replacing you costs the building a substantial fraction of a year's rent before the new tenant pays a normal month. A renewing tenant makes all of that disappear, and that disappearing bill is your negotiating budget. A landlord who opens the renewal conversation with a rent increase is betting you haven't done this arithmetic.
What you lose if you move
A move triggers the one-time stack all over again: a buildout of the new space beyond whatever allowance you win, a second letter of credit posted before the first winds down, furniture and cabling to the extent the floors differ, the physical move, and, the line everyone forgets, downtime and distraction during the transition. Against all that, a modestly lower asking rent at the new address can take years to break even. This is not an argument against moving; it is an argument against comparing two asking rents and calling it analysis.
When moving wins anyway
Three situations flip the math decisively. You've outgrown the floor, a team that no longer fits pays for the mismatch daily, and no renewal discount fixes a space problem. The building is declining, deferred maintenance, emptying floors, a landlord disinvesting; renewal locks you to a trajectory. Or the market has repriced beneath your rent, if comparable space now leases meaningfully below what you pay, the gap can fund the entire one-time stack and still save money, or, used differently, force a serious renewal offer.
The timeline: start at 12 to 18 months
Renewal leverage is a function of time. Start eighteen months out and you can run a genuine alternative search, negotiate calmly, and let the landlord price the real risk of losing you. Start four months out and everyone in the room knows you can't actually leave, a custom relocation takes longer than that. Worse than late is over: holding over past the lease end without a deal commonly costs one and a half to two times the rent, on the landlord's terms. The calendar is the strategy; everything else is execution.
How to run it
Run a real search, not a bluff. Tour genuine alternatives, get to a letter of intent on the best of them, and price the full move honestly, because the renewal negotiation only works if the walk-away is real, and occasionally the search wins on the merits and you should actually move. Then negotiate the renewal like the new deal it is, the same levers apply: market data on comparable floors, your alternative's economics on the table, and a concession ask that mirrors what a new tenant would receive. Landlords price renewals against your credibility.
What a good renewal includes
Not just a rent number. A refresh allowance, renewal-cycle money for carpet, paint, reconfiguration, is normal for tenants who ask and mythical for tenants who don't. Free months at renewal exist for the same reason they exist on new deals. An escalation reset or cap matters more than face rent on a longer extension. Term flexibility, a shorter renewal, or one with options, prices your uncertainty honestly. And any building problem you've lived with for years is at its most fixable in the ninety days before you sign again. The renewal is the one moment the building competes for you. Collect.
The math template
Put the two futures side by side over the same horizon, say five years. For the renewal: proposed rent with escalations, minus concessions, plus the refresh you'd fund yourself. For the move: the new rent with escalations, minus its concessions, plus the buildout gap, furniture and cabling delta, the second letter of credit's cost of capital, moving costs, and a real number for downtime. Divide both by months and by heads. The answer is rarely the one the asking rents suggested, and it is the only version of this decision that deserves the word.
How early should we start a renewal negotiation?
Twelve to eighteen months before expiry. That window fits a genuine alternative search, keeps a real relocation possible, and forces the landlord to price the actual risk of vacancy. Inside six months, the leverage inverts.
Do renewals really get free rent and allowances?
Yes, refresh allowances, free months and escalation resets are all normal renewal concessions for tenants who negotiate. The landlord is saving the entire cost of replacing you; a share of that saving is the market rate for staying.
What is holdover and why does it matter?
Staying past lease end without an agreement. Leases commonly price holdover at one and a half to two times the rent, and it surrenders your negotiating position entirely. The holdover clause is the deadline that makes the 12-to-18-month rule real.
Should we use a broker for a renewal?
Yes, and specifically a tenant-side one. The landlord will have professional representation and better information; a renewal negotiated alone against that is priced accordingly, and commission structures mean tenant representation typically costs you nothing out of pocket.
Can the landlord simply refuse to renew?
Absent a renewal option in your lease, yes, the space is theirs at expiry. Which is the argument for negotiating renewal options into the original lease, and for starting the conversation early enough that a refusal is a plan-B trigger rather than a crisis.
