What happens when a commercial real estate loan matures—but the property cannot support the same loan amount anymore? That difference is called the refinance gap.

This article demystifies net leases in U.S. commercial real estate. It explains how real estate taxes (RET), insurance, and CAM are reimbursed under single, double, and triple net leases, and shows—using a sample Excel model—how each structure affects a landlord’s NOI and risk. It also highlights why tenants agree to NNN leases, along with the key benefits and risks they face.

IFERROR helps clean up CRE variance models by replacing error codes with clear outputs like “N/A”, “Check”, “New Line Item”, or 0. It keeps variance and variance‑percentage columns readable even when prior‑year values are zero or inputs are missing, improving how underwriters interpret performance. But because IFERROR wraps all error types into one result, it must be used carefully so real formula or data issues are not silently hidden.

Net Effective Rent (NER) reveals the true average rent per square foot per year after factoring in free rent, TI allowances, commissions, and expense recoveries. Using discounted cash flows and PMT, NER turns complex lease structures into a single comparable number, helping landlords and tenants make apples‑to‑apples decisions across different spaces, terms, and markets.

Technical guide to how lenders size CRE loans using LTV, DSCR, debt yield and mortgage constants, illustrated through a full Excel-based case study. The article walks step-by-step from NOI and value to constrained loan amount, shows how each metric produces a different max loan, identifies the binding constraint, and then recomputes all credit metrics at a custom, business‑plan‑driven loan amount.

Breakeven occupancy is the minimum occupancy at which a multifamily property’s income covers operating expenses and debt service, with zero cash flow after debt. This article explains why it is a core downside‑risk metric, how it complements DSCR and LTV, who relies on it (lenders, equity, asset managers), and shows a simple formula and numerical case study so investors can plug it directly into their Excel underwriting.
