How Lease Structure Shapes a Commercial Property’s Risk
A commercial building is often described by its location, age, tenant mix, and physical condition. Those factors matter, but the lease is where much of the property’s risk is actually allocated. Two buildings on the same block can produce very different outcomes for an owner or lender because one lease package shifts more cost, vacancy, and capital responsibility onto the landlord than the other. Underwriting is, in large part, the discipline of translating lease clauses into a realistic view of cash flow durability, refinancing capacity, and exit value.
The Lease Is the Risk Map
Lease structure determines how long income is contracted, who pays for what, and which party bears the cost of change. Base rent alone says little. A rent roll with strong-looking in-place rents can conceal near-term rollover, below-market escalations, or recovery language that leaves the landlord exposed to rising operating costs. The public biography of Mark Tersigni describes a career spanning public accounting, corporate finance, and commercial real estate investment, with work centered on how assets are valued, financed, and positioned for sale. That perspective is useful because lease risk is not only a legal issue; it flows directly into valuation and debt sizing.
In practice, underwriting starts with reading the actual leases rather than relying on a summary rent roll. Term, renewal rights, termination options, expense recoveries, co-tenancy provisions, exclusivity clauses, and landlord obligations all affect the property’s future cash flow. A lease abstract should capture the economics and the obligations that can turn into capital calls or revenue interruptions. Complete Property Advisors, where Mark Tersigni is listed as founder, offers consulting and hourly analyst services to commercial real estate owners and investors, including cash flow underwriting, hold/sell/refinance analysis, transaction due diligence support, Excel model creation and maintenance, business planning, and employee training. Those services reflect the practical work of turning lease terms into a model that lenders, owners, and asset managers can use.
Base Rent, Credit, and Contractual Durability
Base rent is the starting point, but tenant credit and lease guarantees give it meaning. A below-market lease with a strong covenant may be safer than an above-market lease with a fragile tenant and weak guaranty. Percentage rent, scheduled bumps, free rent, and tenant improvement allowances also change the timing and quality of returns. A lease that looks generous on a per-square-foot basis can be less valuable after leasing commissions, downtime, and landlord-funded improvements are included.
Underwriting also has to separate contractual income from assumptions. A model can project renewal probability, but the lease controls the tenant’s rights. Renewal options, early termination rights, and expansion options can transfer value from the landlord to the tenant.

Expense Pass-Throughs and Recovery Mechanics
Recovery language is one of the most underappreciated parts of commercial lease risk. In a triple-net structure, tenants may reimburse the landlord for taxes, insurance, and common-area maintenance, but the details matter. Caps on controllable expenses, base-year stops, gross-up provisions, administrative fees, exclusions, and tenant audit rights all influence net operating income. If expenses rise faster than recoveries, the landlord absorbs the difference.
Property format affects how those clauses play out. Open-air centers often have parking fields, landscaping, lighting, and common-area costs that differ from the shared systems and interior common areas of enclosed malls. The lease structure should match the physical asset. A retail center with many small tenants may require careful allocation of common-area maintenance, while a mall with large anchors may have complex expense-sharing and co-tenancy provisions. The goal is not to eliminate risk but to see where it sits and whether the rent is adequate compensation for it.
Term, Options, and Rollover Risk
Weighted average lease term is a useful summary, but it can hide concentration. A property with a long average term may still have a cluster of expirations in the same year or a single tenant whose departure would change the asset’s character. Short-term leases can offer mark-to-market upside, but they also create leasing costs and downtime. Underwriters need to look at expiration schedules by tenant, by credit, and by space type, then stress the property for vacancy, concessions, and capital needs.
Financing adds another layer. Lenders evaluate debt service coverage, loan-to-value, tenant rollover, and lease provisions that affect collateral. A lease that permits a tenant to terminate early, go dark, or reduce space can weaken the lending case even if current rent is strong.

Anchor Provisions and Physical Format
Anchor tenants can stabilize a property, but their leases often carry the most complicated risk provisions. Co-tenancy clauses may allow an anchor to pay reduced rent or terminate if other tenants leave. Go-dark provisions may let a tenant stop operating while continuing to pay rent, which can still hurt traffic and smaller tenants. Exclusivity and radius restrictions can limit what the landlord can lease to future tenants. These clauses are not side issues; they shape the property’s leasing strategy and ultimate sale price.
The September 2026 IBTimes article by Tom Robbins, which outlines the investment case for open-air retail centers, uses Mark Tersigni and his underwriting experience to frame a comparison between open-air centers and enclosed malls. As the piece’s published argument goes, grocery and everyday-need tenants can differ from department-store-dependent malls, and parking, common-area costs, occupancy versus lease expirations, expense sharing, capital needs, and anchor-lease provisions all affect the investment case. The article also cautions against broad “retail is dying” narratives that ignore property-level differences. That is a lease-level point as much as a retail-sector point: the same headline can mean very different things for two centers with different tenant bases and contractual structures.
Underwriting the Lease, Not Just the Property
A disciplined underwriting process reads leases closely, builds a clean abstract, tests recoveries, maps rollover, and models the capital required to retain tenants. It should also consider how lease terms interact with debt covenants and exit assumptions. A buyer may pay for in-place income, but the next buyer will underwrite the same leases again. Asset management then becomes the work of protecting that income through renewals, expense control, capital planning, and proactive leasing.
Lease structure does not remove risk from commercial property. It assigns risk to specific parties at specific times, often in language that is easy to overlook until a tenant exercises an option or an expense line outpaces recovery. For owners, lenders, and investors, the most reliable way to understand a property’s risk is to start with the lease and follow it through the cash flow, the financing, and the eventual sale.
