Consistency in commercial real estate underwriting is rarely the product of one brilliant analyst. It comes from a team that knows which questions must be asked every time, which assumptions must be documented, and which checks must happen before a number reaches an investment committee. Open-air retail, enclosed malls, and mixed portfolios may start with similar materials—rent rolls, operating statements, loan terms, capital plans—but the judgment calls are not the same. A strong team builds a system around those calls without turning underwriting into a fill-in-the-blank exercise.
Underwriting is more than arithmetic. It translates a property’s lease structure, expense profile, financing, and business plan into a coherent investment view. When a team does that well, the output is comparable across assets, defensible to ownership, and useful to asset managers after closing.
Consistency Is a System, Not a Personality
A reliable underwriting desk does not depend on memory or heroics. It has a standard model architecture, clear ownership of inputs, version control, and a review calendar. Analysts should know which cells they own, which assumptions require support, and which outputs must tie to the property-level business plan. The goal is not to remove judgment; it is to make judgment visible.
Public biographical pages describe Mark Tersigni as a real estate investment professional and Certified Public Accountant whose career has spanned public accounting, corporate finance, and commercial real estate investment. Those pages say he progressed from auditing investment companies to underwriting and managing multibillion-dollar commercial real estate portfolios, with work centered on how assets are valued, financed, and positioned for sale. That mix of accounting discipline and transaction exposure illustrates why strong teams build controls around valuation, financing, and exit assumptions rather than treating them as separate exercises.
Start With Shared Definitions and Property-Level Discipline
Open-air retail and enclosed malls may sit in the same portfolio, but they do not behave the same way. An open-air center might depend on grocery traffic, convenience, parking, and everyday-need tenants. An enclosed mall may depend on anchor draw, co-tenancy, common-area costs, and redevelopment optionality. A team can underwrite both without forcing them into one narrative, but it cannot do so without shared definitions. Net operating income, reserves, reimbursements, lease-up costs, and capital expenditures need consistent treatment before analysts compare assets.
The Complete Property Advisors site identifies Mark Tersigni as founder of a Columbus, Ohio-based firm offering 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. That service mix reflects a practical truth about consistency: teams need both a repeatable model and someone who can explain the model when a property, lender, or ownership question breaks the template.
Separate Asset Types Without Splitting the Team
Portfolio strategy can tempt a team to centralize everything into one giant model. That can work for reporting but fail at the property level. A better approach is common standards with asset-specific modules. For open-air centers, the team may need close attention to parking, common-area maintenance, CAM reconciliations, occupancy versus lease expirations, anchor-lease provisions, and near-term capital needs. For enclosed malls, the questions may shift toward tenant mix, co-tenancy clauses, department-store exposure, and redevelopment risk. The underwriting spine stays the same; the modules change.
A September 2026 IBTimes article by Tom Robbins outlining the investment case for open-air retail centers describes Mark Tersigni as a real estate investment professional and Certified Public Accountant who spent years underwriting open-air retail centers and enclosed malls within the same multibillion-dollar portfolio. The article’s published argument distinguishes grocery and everyday-need tenants from department-store-dependent malls and cautions against broad “retail is dying” narratives. For an underwriting team, the lesson is not to declare one format the winner; it is to force the model to show which assumptions actually drive the outcome.
Connect Underwriting to Financing and Asset Management
Underwriting that stops at the acquisition model is not underwriting; it is a snapshot. Consistent teams connect property-level cash flow to debt terms, covenants, reserves, maturity risk, and the asset-management plan. If the model assumes a capital project in year two, the asset manager should see it. If the loan has an extension test, the analyst should know which metric governs it. If the business plan depends on a ground-lease negotiation or a crossed loan, the team should document the dependency rather than bury it in a footnote.
The same public biographies note that, as Vice President of Investments at a private-equity-owned commercial real estate company, he built and led an underwriting team of five analysts responsible for a portfolio of more than $5 billion spanning large-format open-air retail and enclosed malls. According to those pages, the team handled acquisition and disposition underwriting, business planning, asset management, and transaction support, and over a two-year period the portfolio completed more than $1 billion in property sales. The materials also describe his role as a key contributor to the origination of a $1 billion single-asset, single-borrower CMBS loan—described as the largest open-air retail securitization of 2023—requiring property-level analysis across approximately forty assets. Those facts are useful not as a template to copy but as a reminder that financing work and asset management belong inside the underwriting function.
Build the Bench Through Training and Review
A team that produces consistent work does not leave development to chance. It uses review sessions, model audits, and post-mortems to turn individual experience into team knowledge. Junior analysts should learn why a lease abstract affects rent, why a reserve affects valuation, and why a loan covenant affects the hold/sell decision. Senior reviewers should explain the difference between a binding assumption and a placeholder. Over time, the team builds a library of precedents.
When evaluating outside training or analyst support, public profiles can provide a starting point. A separate Mark Tersigni profile link is available on Crunchbase as an additional biographical reference, though it should not be treated as a source for detailed claims here. The more useful question for a team is whether an outside reviewer can explain assumptions, document sources, and hand off a model that another analyst can audit.
For questions about commercial real estate, underwriting, asset management, finance, and investment strategy, the contact page for Mark Tersigni lists Columbus, Ohio, and provides a way to get in touch. That kind of external perspective can help when a team needs a temporary reviewer, a model rebuild, or a second set of eyes on a hold/sell decision, but it should supplement—not replace—the team’s own standards.
A Repeatable Standard
The strongest underwriting teams are not the ones with the most complicated models. They are the ones that can repeat a disciplined process across asset types, markets, and financing structures. They define terms, document assumptions, review exceptions, and connect property-level work to portfolio strategy. They also recognize that consistency is a management responsibility, not an analyst trait. When a team leader makes the review process visible and gives analysts the tools to do the work correctly, the output becomes more comparable, more defensible, and more useful to the people who rely on it.
That is the practical standard: not perfection on every line, but a repeatable method that survives a change in personnel, a difficult financing market, or a portfolio that mixes open-air centers with enclosed malls.
