An Improving Office Market Still Requires Property-Level Discipline

Recent research suggests the office market is moving toward greater stability, although performance remains uneven. Cushman & Wakefield reported national vacancy of 19.8% in the third quarter of 2026 and found that Class A buildings accounted for approximately two-thirds of leasing volume. Those figures point to improving demand for higher-quality space rather than a recovery shared equally across the inventory.

Concession trends tell a similarly mixed story. CompStak's October office research found that free-rent concessions have eased in higher-quality buildings during 2026, while the pattern has been less pronounced in Class B and C properties. That difference matters to owners evaluating a leasing strategy because a stronger overall market does not necessarily mean their property can reduce incentives or achieve higher effective rents.

For existing investments, leasing assumptions should be revisited against actual proposals and executed leases rather than increased simply because national market reports show improvement. The financial implications will depend on the property's competitive position, tenant mix, remaining lease terms, and capital required to execute the business plan.

A Signed Lease Is Not the Same as Collected Rent

A leasing report may show meaningful progress while the cash flow forecast has yet to reflect any corresponding income. A tenant may sign today but require months of design, permitting, construction, and move-in preparation before the lease commences. Rent may not begin until after an additional abatement period, depending on the negotiated terms.

A current office asset management model should distinguish between executed lease dates, delivery obligations, occupancy, rent commencement, and the expiration of free rent. Treating these milestones as one event can pull revenue forward and make the property's near-term liquidity appear stronger than it is.

Renewals require similar attention. Retaining a tenant may protect future occupancy, but an early renewal with additional free rent, a revised rate, or landlord-funded improvements can change cash collections well before the contractual expiration date. The relevant question is how the negotiated economics affect the hold period, not just whether the tenant stays.

Keeping Leasing Costs Separate From Operating Performance

Tenant improvements and leasing commissions can create substantial cash requirements during an office lease-up, particularly where owners are repositioning space to attract new tenants. These costs also occur at different points. Commissions may be payable in installments tied to execution and commencement, while improvement expenditures follow construction draws and landlord delivery obligations.

Those outlays generally sit below net operating income in property-level investment analysis, which means an improving NOI forecast can coexist with constrained cash flow after capital expenditures. Sponsors who evaluate leasing success only through stabilized income may overlook the equity required to fund the transition.

The financial model should carry a separate capital schedule for each material lease, including anticipated improvement costs, commission payments, landlord work, and any reimbursement assumptions. Maintaining that schedule alongside the operating forecast makes it easier to evaluate whether reserve balances and property cash flow can fund the leasing plan without an unexpected capital contribution.

Maintaining a Rolling Forecast That Reflects Actual Leasing

A static annual budget is rarely enough for a property with active leasing, tenant turnover, or a substantial capital program. The monthly forecast should be updated as proposals become letters of intent, letters of intent become signed leases, and anticipated delivery dates move.

Rather than applying a general vacancy assumption across the building, owners can model individual suites and tenants, taking into account lease expirations, renewal probabilities, downtime, contractual rent steps, and concession schedules. The purpose is not to suggest that every leasing event can be predicted precisely, but to show how the investment's financial position changes as better information becomes available.

This approach also improves variance analysis. If operating cash flow differs from budget, the sponsor can separate changes caused by rent commencement, tenant turnover, leasing concessions, operating expenses, and capital spending. Ongoing commercial real estate asset management is most useful when those differences lead to updated decisions rather than a retrospective explanation of performance.

Planning for Tenant Rollover Before It Becomes a Liquidity Problem

Lease expirations create more than occupancy risk. A large tenant rolling out can interrupt revenue, trigger downtime, and require a significant investment before replacement rent begins. Even where a renewal is expected, owners should consider the capital package that may be required to secure the tenant's next commitment.

A useful rollover analysis groups exposures by timing, square footage, rent contribution, tenant concentration, and realistic renewal prospects. The model should also distinguish between space that can be marketed with limited work and suites likely to require substantial repositioning. These distinctions affect the amount of cash a property needs to hold in reserve.

For sponsors evaluating a value-add acquisition, the same discipline belongs in the original office acquisition underwriting. A projected increase in occupancy only creates value if the expected rent, timing, and required leasing capital make economic sense together.

Connecting Leasing Forecasts With Debt and Investment Decisions

The lease-up forecast should inform financing decisions throughout ownership. Lenders may evaluate in-place income, future cash flow, leasing reserves, tenant concentration, and the timing of stabilization differently, so the assumptions used for capital markets execution should remain consistent with the operating model.

A building approaching loan maturity may have promising leasing momentum but limited cash available to support near-term obligations. Conversely, an owner with strong committed leases and a credible commencement schedule may have a different set of financing options than current collections alone would suggest. Neither situation should be evaluated without understanding what the remaining lease-up will cost.

Keeping leasing, capital spending, and financing in one connected forecast also helps sponsors compare hold, refinance, recapitalization, and disposition scenarios. Each alternative should reflect the actual capital still required rather than assuming that signed leases immediately translate into stabilized proceeds.
