• Real properties differ in location, condition, leases, zoning, title, taxes, financing, vacancy, capital needs, environmental risk, and market liquidity. Forecasts and ratios are not appraisals, loan offers, tax opinions, or investment advice.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Reconcile assumptions to leases, operating statements, surveys, tax records, lender terms, comparable evidence, and physical inspection; test downside scenarios and obtain qualified local advice.
