What is re-leasing in commercial real estate?
Re-leasing is the process of letting a commercial unit to a new tenant after the existing tenant leaves or its lease expires. Its economics turn on two variables: the re-leasing spread, the new passing rent versus the old, and the void, the downtime between tenancies during which the unit earns nothing. In industrial portfolios these two assumptions usually dominate an asset's hold-period return, because income is concentrated in a few large units and a single re-let resets a meaningful share of the rent roll. Scayled improves the outcome by surfacing the verified replacement demand for a unit before it empties, so re-leasing starts early and the void is compressed.

Re-leasing defined and why it is a distinct event
Re-leasing is the transaction that replaces a departed or expired tenant with a new one. It is distinct from a renewal, where the sitting tenant stays, and from a rent review, which adjusts terms inside an existing lease. Re-leasing means the unit changes hands, which makes it the moment a landlord crystallises the gap between what the space used to earn and what the market will now pay for it.
That moment is also when the largest cash outflows cluster: re-marketing, agent fees, rent-free incentives, and capital for fit-out or refurbishment to make the unit lettable to a different occupier type. A cross-dock configured for one 3PL may need racking changes, dock-door adjustments, or office reconfiguration before the next tenant signs. Re-leasing is therefore both an income event and a capital event, and the two interact.
Understanding re-leasing as a discrete, expensive event, rather than a smooth continuation of income, is the starting point for modelling its two economics honestly.
The re-leasing spread: capturing or surrendering reversion
The re-leasing spread is the difference between the new rent and the rent the previous tenant paid. A positive spread captures reversion: the unit was under-rented and relets higher, lifting net income and, through the cap rate, value. A negative spread surrenders it: the passing rent was above market, often because it was set at a cyclical peak or carried fixed uplifts, and the unit relets lower. Industrial markets that have run hot can produce large positive spreads; markets that have softened produce the opposite.
The spread is where mark-to-market lives. A fund's asset business plan typically assumes a reversion at the point of re-let, and whether that assumption holds is one of the biggest swing factors in realised return. Over-optimism here flatters a model that the market later corrects, because the spread is only proven when a real tenant signs at a real rent.
Crucially, the spread depends on demand depth. A unit with several genuinely interested occupiers relets nearer the top of the range; a unit marketed cold into a thin submarket relets nearer the bottom, often with heavier incentives to close. Knowing who actually wants the space changes the spread you can hold out for.
The void: downtime is the silent return killer
The void is the period between the old tenant leaving and the new tenant paying, and it is frequently the larger of the two economics. On a small multi-let unit a void might be weeks; on a big-box logistics shed it can run six to twelve months or more in a soft market, before factoring the rent-free period the new tenant negotiates on top. Every month of void is income lost outright, and unlike a rent change it is never recovered.
Voids also compound. During downtime the landlord still carries empty-rates liability, service-charge shortfall, security, and holding costs, so the unit moves from earning to costing. On a concentrated industrial asset, a single extended void can swing a year's same-store NOI and, because value tracks NOI through the cap rate, dent the valuation that capital partners are marked against.
This is why the timing of re-leasing matters as much as its terms. A void is not only a function of market depth; it is a function of when marketing starts. A unit re-marketed the day a tenant hands back keys carries the full void; a unit where the fund saw the departure coming and lined up demand in advance can shrink that void to weeks.
Why re-leasing assumptions dominate the hold-period model
In an industrial asset business plan, the cash flows you already hold, the in-place leases, are relatively certain. The uncertain, high-leverage assumptions are what happens at expiry and re-let: renewal probability, reversionary rent, void length, and incentives. Because income is concentrated, a single large unit's re-leasing assumption can move the whole asset's projected return more than any other input, including the exit cap rate in many cases.
ARGUS Enterprise and similar DCF tools model these cash flows precisely, but they model the assumptions the analyst feeds them. They assume a renewal probability and a void; they do not observe whether a specific tenant is actually about to leave, or whether real replacement demand exists for that specific unit. The model is only as good as the re-leasing inputs, and those inputs are usually guesses dressed as forecasts.
Sharpening those inputs with real-world evidence, who is likely to vacate and who is likely to take the space, is the single highest-value improvement available to an industrial hold-period model, precisely because re-leasing is where the return is won or lost.
Improving re-leasing outcomes: start early, know real demand
Two things improve a re-leasing outcome: starting before the unit is empty, and starting with verified demand rather than a cold marketing campaign. Together they compress the void and strengthen the spread, because a fund negotiating from a position of known interest concedes less and waits less. The earlier and the more specific the demand, the better both economics resolve.
Scayled supplies both halves. It monitors the portfolio and the surrounding submarket for the signals that precede a departure, contract losses, M&A, restructuring, distribution-network changes, so the fund knows a re-let is coming before a break notice or surrender request lands. Then, for that specific unit, it identifies the adjacent occupiers who genuinely fit the space, each with the verified decision-maker, so re-marketing opens with real names instead of a vacancy advert.
Scayled does not administer the lease or model the DCF; those stay in your existing systems. It fills the gap none of them cover: the forward read on which unit is about to need re-leasing and who will take it. Access is by request. Request access and Scayled works your first at-risk unit free, showing you the replacement demand for the unit you choose so re-leasing can start before the void does.
