Managing Lease Rollover and Expiration Risk
Owners and lenders assess rollover risk by matching expiring rent to the cash needed before replacement rent starts and to the debt payments due in that gap. Expiration concentration shows how much income is exposed and when. A dated cash schedule shows what the exposure costs. Owners reduce the risk by spreading expirations across the calendar and by funding the shortfall that remains under a defined downtime scenario.
Area share and rent share measure different exposures
Rollover exposure is the share of leased space or contractual rent that reaches expiration in a defined window. The two measures match only when the expiring space pays the same rent per square foot as the rest of the building. A large floor on an old low rent can show a big area share and a small income share, and a small suite on a high rent can do the reverse.
Tenant count answers a third question. Five small expirations can carry less income than one large one, so a schedule quoted by number of tenants hides the denominator that matters for debt service.
The window matters as much as the denominator. A calendar bucket splits two expirations that sit one month apart on either side of a boundary, yet both land inside the same cash stress interval. A rolling schedule measured from a stated date avoids that split.
Each expiring lease then branches. A renewal keeps the space occupied at a new rent, with concessions and lease costs attached. A departure creates downtime with no rent from that space, followed by replacement rent from its commencement date. The two branches need separate cash schedules.
Spreading expirations lowers the chance that a large block of turnover lands in a single month. That changes when exposure arrives. It supplies no cash during downtime and sets no replacement rent.
Market vacancy sets the price of an expiration
The cost of an expiration depends on the market it falls into. When market vacancies are high, expirations produce larger declines in income and occupancy. A downtime assumption calibrated in a tight market and reused in a soft one understates the loss on the same lease.
Office adds a demand question on top of the rent question. Uncertainty about remote and hybrid work has left investors cautious about office demand at expiration. Contract rent describes the lease before it ends and says little about how much space the tenant will want afterward, so renewal probability and renewal footprint are open inputs.
Rollover also changes what the building is. Significant rollover can shift the tenant mix and change the experience of the whole property, an effect a model tracking only replacement rent leaves out.
“However, when market vacancies are high, expirations result in greater declines in income and occupancy rates.”
Rent resets cut both ways: logistics and net lease portfolio data
Expiration is a repricing event as well as a risk. In one large logistics portfolio, market rent growth combined with in-place rents sitting below market drove strong rent change on rollover. Leases that commenced in the reporting year showed 76.4% rent change on a net effective basis, and new leases and renewals carried an average term of 66 months.
A 66 month term is 5.5 years, so each reset also fixes the next rollover date in the calendar.
A net lease portfolio reports the same idea as a recapture rate, which is new annualized base rent divided by previous rent. For its re-leased units in one annual report, new rent was $301.99 million against previous rent of $290.61 million, a 103.9% recapture rate.
Both figures are rent rates for one portfolio in one period. Neither describes how long the space sat empty, what concessions were paid or what the lease cost the owner in cash. A high rent change on a lease that commenced late can still leave a thin year of collections.
How lenders tie rollover to the loan term
A lender reads rollover against two dates: the scheduled payments and maturity. An expiration inside the term cuts the cash that covers debt service. An expiration just past maturity still bears on the income a refinancing lender would underwrite.
Rating criteria separate two vacancy layers. The base layer reflects stabilized levels, future projections or an assumed minimum that varies by property type. A second layer of additional vacancy can be added for lease rollover. Each layer needs a defined income loss, or the same empty space gets counted twice.
Default models also encode timing. One proposed model update expresses the largest tenant’s expiration relative to the loan term, so a dominant lease ending well before maturity registers differently from one ending after it.
Supervisory review applies the same logic to troubled loans. In a restructuring example, an examiner classified the loan substandard on limited debt service capacity, sporadic delinquencies, a higher loan to value ratio after a new appraisal and near-term lease expirations that posed cash flow risk. The expirations were one factor among several, which fits how exposure is read: by what remains of repayment capacity once the rent stops.
Worked example: a 100,000 square foot building with 30 percent of the space expiring
This hypothetical example compares an immediate renewal with six months of downtime over the same 12 months. The building has 100,000 square feet, and 30,000 square feet expire on day one. That space is 30,000 divided by 100,000, multiplied by 100, or 30% of the area. The remaining occupied area is 100,000 minus 30,000, or 70,000 square feet.
Rent is $30 per square foot throughout, so the occupied space pays 70,000 multiplied by $30, or $2,100,000. Annual operating expenses and annual debt service are each $1,200,000. Opening reserves are $600,000. Both cases use a replacement rent of $32 per square foot and a tenant improvement payment of $10 per square foot on the expiring space, which is 30,000 multiplied by $10, or $300,000, paid at the start. Leasing fees are zero in both cases, operating expenses continue during downtime and all other cash flows arrive evenly.
Base case, the tenant renews immediately. Rent from the renewed space is 30,000 multiplied by $32, or $960,000. Total rent is $2,100,000 plus $960,000, or $3,060,000. Net operating income is $3,060,000 minus $1,200,000, or $1,860,000, and coverage is $1,860,000 divided by $1,200,000, or 1.55x. Cash after debt service is $1,860,000 minus $1,200,000, or $660,000. After the improvement payment it is $660,000 minus $300,000, or $360,000, and ending reserves are $600,000 plus $360,000, or $960,000.
Stressed case, the space is vacant for 6 months and occupied at the new rent for the other 12 minus 6, or 6 months. Rent from that space is 30,000 multiplied by $32, multiplied by 6 divided by 12, or $480,000. Total rent is $2,100,000 plus $480,000, or $2,580,000. Net operating income is $2,580,000 minus $1,200,000, or $1,380,000, and coverage falls to $1,380,000 divided by $1,200,000, or 1.15x. Cash after debt service is $1,380,000 minus $1,200,000, or $180,000, which is $120,000 short of the $300,000 improvement payment (300,000 minus 180,000). Ending reserves are $600,000 minus $120,000, or $480,000.
Ending reserves differ by $960,000 minus $480,000, or $480,000. That equals the rent the vacant half-year removed, since the replacement rent per square foot is identical in both cases.
The path matters more than the end balance. After the improvement payment, reserves are $600,000 minus $300,000, or $300,000. During the six vacant months, rent from the occupied space is $2,100,000 multiplied by 6 divided by 12, or $1,050,000. Operating expenses and debt service are each $1,200,000 multiplied by 6 divided by 12, or $600,000. The shortfall is $600,000 plus $600,000 minus $1,050,000, or $150,000, so reserves fall to $300,000 minus $150,000, or $150,000 before the new tenant pays.
The second half then adds $330,000: rent of $1,050,000 plus $480,000, or $1,530,000, less $1,200,000 of expenses and debt service. Reserves recover to $150,000 plus $330,000, or $480,000, matching the annual figure. Coverage stays above 1.00x in both cases, and neither ratio is a lender requirement. The low point shows that reserves hold a $150,000 balance at the thinnest moment, a fact the annual coverage ratio cannot show.
Staggering changes timing, reserves change funding capacity
Moving an expiration moves the whole branch of receipts and lease costs attached to it. Adding a funded reserve raises the opening cash that absorbs the resulting shortfall. These are separate levers, and a schedule can improve on one while the other stays unchanged.
The decision test is the maximum cumulative cash deficit under a fixed downtime assumption. An extension that shrinks that deficit has reduced the funding need. An extension that pushes the deficit into a neighboring cluster of expirations has only relocated it, and the revised dated schedule shows which happened.
A renewal also splits rate from timing. Annualized rent describes income once rent is payable. The commencement date sets when collections begin, and an improvement payment carries its own payment date, so the comparison needs one common period to join them.
Mistakes that distort rollover coverage and liquidity
Labeling the expiration schedule by tenant count confuses the number of lease decisions with the amount of income exposed. A rent denominator fixes that, and area stays useful as a separate view because the expiring space may pay a different rent per square foot.
Applying replacement rent to the whole analysis period erases downtime. Annualized rent is a rate, and collected rent is that rate multiplied by the months it is payable. In the example above, the same $32 rent produces $960,000 in one case and $480,000 in the other.
Calling coverage the cash left after every outlay mixes definitions. Coverage divides net operating income by debt service, and the improvement payment sits below net operating income. Coverage of 1.15x can sit beside a $120,000 shortfall after improvements.
Stacking a rollover vacancy deduction on a general vacancy allowance can count the same lost rent twice when both cover the same space and months. The opposite error also occurs: a stabilized allowance may leave a particular expiration’s timing unmodeled. A reconciliation has to name the income loss assigned to each layer.
Reading a rent change figure as a cash result skips the downtime and the costs. A 76.4% rent change on a net effective basis describes the new rate against the old. It says nothing about months of empty space or the improvement payments that came first.
Judging reserve adequacy by the ending balance ignores the low point. In the example the annual balance of $480,000 hides a trough of $150,000 reached before replacement rent starts.
Lease rollover questions for ownership and credit review
What does the expiration percentage measure? A stated denominator separates area exposure from contractual rent exposure.
Which expirations fall inside the same cash stress interval? Grouping by modeled interval shows overlapping income gaps even when the contractual dates differ.
What rent is payable before and after each expiration? Separate rates keep an annualized replacement figure from being applied to a vacant month.
When does replacement rent enter the cash schedule? The collection start date sets how much of the period produces income.
Which lease costs sit outside net operating income in the analysis? An explicit classification connects the coverage ratio to the separate cash calculation.
Does the general vacancy allowance already include the modeled rollover loss? A reconciliation shows any duplicated rent reduction.
Where is the lowest cash balance before replacement occupancy? The interim low point measures funding pressure that an ending balance conceals.
How does the expiration schedule line up with debt payments and maturity? That alignment shows which obligations fall before income recovers.
Does a proposed extension reduce concentration or relocate it? A revised schedule shows how exposure is now distributed across months.
