Office Development Underwriting
Office development underwriting tests whether a defined office product can be delivered, leased and financed at a supportable total basis. It connects market evidence with a project schedule and cash-flow model; a low aggregate vacancy rate or a premium asking rent alone does not demonstrate feasibility.
Updated
Office Underwriting and Lease Structures covers operating lease and recovery mechanics. This concept focuses on the development decision and the transition from a planned project to occupied income-producing space.
Source-supported distinctions
- Competitive pipeline: Colliers’ Q1 2026 leading-markets public summary combines active construction and renovation, with a separately reported preleased share. That tracked universe does not represent all U.S. office supply, and preleasing is not completed occupancy.
- Delivery status: C&W’s Q2 2026 Savannah report describes a largely prospective pipeline while its table carries an aggregate under-construction field that is not fully reconciled to the narrative projects. Project-level evidence is needed before treating the aggregate as scheduled delivery.
- Cost scope: C&W’s preserved 2026 fit-out summary distinguishes buildout benchmarks and expanded cost components. Fit-out cost is not automatically a landlord TI allowance or a complete ground-up development budget.
Curator synthesis: development decision sequence
| Decision | Evidence needed | Modeling consequence |
|---|---|---|
| Product and competing supply | Target tenant segment, comparable product and submarket; project-by-project construction, renovation and proposed supply | Separate quality and location assumptions; retain each competitor’s actual delivery status |
| Site and delivery | Site control, approvals, design, utility service, construction bids and milestone schedule | Model scope, timing, contingency and carrying costs explicitly |
| Leasing and occupancy | Signed commitments, commencement conditions, tenant credit, remaining space and achievable lease economics | Distinguish preleased, delivered, commenced and physically occupied space |
| Total project cost | Land, building/shell, soft costs, fit-out scope, commissions, concessions, contingency and financing costs | Reconcile inclusions and responsibilities; avoid double-counting tenant-funded or landlord-funded work |
| Financing and stabilization | Reviewed draw conditions, leasing conditions, reserves and the operating cash-flow ramp | Test delayed completion and lease-up, cost overruns and funding gaps rather than assuming immediate stabilization |
| Exit or hold | Documented stabilized income assumptions, buyer/lender requirements and a dated exit scenario | Keep future value and refinancing assumptions separate from present bids or market observations |
The sequence is a diligence framework, not a prescribed leverage, preleasing, return or vacancy threshold. Use project-specific contracts and evidence to set model inputs.
Limits and open evidence
The cited summaries do not supply a subject-project construction contract, complete budget, tenant commitments, lender term sheet or achievable exit value. Regional fit-out guides and selected market observations cannot fill those gaps. The Savannah reporting inconsistency remains unresolved here; no pipeline number is reconciled by assumption.
