Understanding vacancies and rent rolls is central to valuing and managing commercial real estate in New York. Whether you’re underwriting a new acquisition, refinancing, or preparing for a sale, the quality of your vacancy and rent roll analysis often determines the credibility of your valuation and the price you can command.
At Lloyd Real Estate Services, our New York Commercial Real Estate Appraisers recommend a disciplined, data-driven approach that pairs document-level scrutiny with market intelligence.Below, we break down how vacancies and rent rolls are analyzed—what to look for, how to model them, and what lenders, buyers, and appraisers expect to see in New York’s competitive markets.
What Is a Rent Roll—and Why It Matters
A rent roll is the foundational document that lists every tenancy in an income-producing property. It typically includes:
- Tenant name and suite
- Lease start and expiration dates
- Current base rent and rent escalations
- Free rent and concessions
- Additional rent (reimbursements, percentage rent)
- Lease type (NNN, modified gross, full-service)
- Security deposits and guarantees
- Options (renewal, expansion, termination)
- Arrears/credit status and move-in/out history
Our New York Commercial Real Estate Appraisers recommend verifying that the rent roll ties to executed leases, amendments, and estoppels. For many assets, a “lease audit” is the fastest way to surface discrepancies before they derail underwriting or due diligence.
Vacancy 101: Physical vs. Economic
Vacancy is not just empty space. It has multiple dimensions:
- Physical Vacancy: Space that is unoccupied.
- Economic Vacancy: Revenue shortfall from free rent, delinquency, credit losses, and below-market leases (loss to lease).
- Stabilized Vacancy: The long-term vacancy rate expected for the asset in its market.
New York Commercial Real Estate Appraisers recommend distinguishing short-term, lease-up vacancy from stabilized vacancy expectations. Lenders often underwrite to stabilized levels after a reasonable absorption period, then blend near-term and long-term assumptions in a cash flow model.
How Vacancies Are Analyzed
At Lloyd Real Estate Services, our New York Commercial Real Estate Appraisers recommend the following steps:
- Establish Market Context
- Market Vacancy and Absorption: Pull current submarket data for comparable buildings (by class, location, vintage).
- Tenant Demand: Track leasing velocity, tour volume, and typical marketing time.
- Concessions: Quantify free rent and TI/LC norms for the submarket.
- Classify Existing Vacancy
- By Space Type: Office vs. retail vs. industrial; small-bay vs. large floor plates.
- By Condition: Shell vs. second-generation; white-box vs. plug-and-play.
- By Lease Impediments: Blocking leases, co-tenancy issues, use restrictions.
- Model Lease-Up
- Absorption Timeline: Apply market-based lease-up months per square foot.
- Achievable Market Rent: Use comparable deals, not just asking rents.
- Concessions and Costs: Free rent, tenant improvements, leasing commissions.
- Credit and Downtime: Include downtime between tenants and potential credit loss.
- Stress-Test Outcomes
- Sensitivity Analysis: Vary rent, downtime, and concessions to see NOI impacts.
- Scenario Planning: Best case, base case, downside case.
Our New York Commercial Real Estate Appraisers recommend documenting every assumption with a sourced note—brokers’ opinions, recent comps, or proprietary data—so the logic is transparent to lenders and investors.
How Rent Rolls Are Analyzed
The rent roll tells the story of cash flow durability. Lloyd Real Estate Services focuses on:
- Lease Expiration Schedule (Rollover Risk): Concentrations of expirations in any 12–24 month period elevate risk. Staggered lease expirations are a positive signal.
- In-Place vs. Market Rent: Identify loss to lease or mark-to-market upside. This is crucial for both direct capitalization and DCF models.
- Tenant Quality and Industry Risk: Credit tenants vs. local operators; sector resilience; guarantor strength.
- Expense Reimbursements: True-up base years, CAM caps, gross-ups, and audit rights. Misstated reimbursements are a common NOI pitfall.
- Options and Clauses: Renewal options (at FMV or fixed), termination rights, contraction options, and percentage rent can materially change cash flow.
- Collections and Arrears: Aging reports reveal hidden economic vacancy. Our New York Commercial Real Estate Appraisers recommend reconciling late payments and any payment plans.
- Space Efficiency: Usable vs. rentable discrepancies, load factors, and measurement standards (BOMA) affect rent roll accuracy.
Where possible, we corroborate rent roll data with lease abstracts, estoppel certificates, and bank statements. New York Commercial Real Estate Appraisers recommend performing random spot checks across large portfolios to confirm consistency.
Turning Data into Value: NOI and Cap Rates
Once vacancy and rent roll inputs are vetted, translate them into cash flow:
- Net Operating Income (NOI): Start with in-place rent, adjust for economic vacancy (delinquency, concessions), add reimbursements, then subtract stabilized operating expenses.
- Direct Capitalization: Apply a market-justified cap rate to stabilized NOI. Make clear whether you used in-place or forward 12-month stabilized NOI.
- Discounted Cash Flow (DCF): Model lease-up timing, rollover events, rent steps, TIs/LCs, and a terminal value with a reversion cap rate.
Our New York Commercial Real Estate Appraisers recommend using both direct cap and DCF for triangulation, especially when lease-up or rollover risk is material. Reconcile to a value range with a reasoned weighting.
Red Flags Our Appraisers Watch For
Lloyd Real Estate Services frequently uncovers issues that can change valuation:
- Aggressive Pro Formas: Unrealistic absorption, below-market concessions, or ignoring downtime.
- Aging Tenants Near Expiry: High-risk expirations with weak credit or declining sectors.
- Overstated Reimbursements: CAM caps or base year errors that inflate NOI.
- Silent Amendments: Uncaptured rent abatements or early termination rights.
- Measurement Mismatch: Rentable square footage overstated relative to BOMA standards.
- One-Time Income: Non-recurring items included in NOI (e.g., lease termination fees).
New York Commercial Real Estate Appraisers recommend addressing these early to preserve deal momentum and credibility.

FAQs
- How often should I update my rent roll?
- Our New York Commercial Real Estate Appraisers recommend updating monthly and after any lease event (new deal, amendment, default).
- What stabilized vacancy should I use?
- It depends on asset class and submarket. We benchmark against current and cyclical norms, often 5–10% for many office assets, lower for stabilized industrial, and variable for retail based on tenant mix.
- Do small arrears matter?
- Yes. Persistent small arrears indicate economic vacancy and can signal credit stress or billing issues.
