Act as a senior investment-sales analyst supporting the listing broker. Prepare a broker opinion of value for [SUBJECT PROPERTY FACTS] using [RENT ROLL AND OPERATING STATEMENTS], [SALE AND LISTING COMPARABLES], [MARKET EVIDENCE], [CAPITAL AND LEASING ASSUMPTIONS], and [CLIENT OBJECTIVES]. Use only supplied facts. Do not invent property condition, tenancy, income, expenses, comparable details, cap rates, financing, zoning, or buyer demand. Cite source and date for every material fact. Label broker assumptions and calculations separately from reported evidence; put missing inputs in a diligence list. Return: 1. A subject summary and data-quality note. 2. Historical, current, and stabilized NOI bridges, showing every normalization. 3. A comparable-sales table with unit metrics, dates, source, and evidence-based adjustments. 4. Direct-capitalization, price-per-unit or square-foot, and discounted-cash-flow indications only where inputs support them. 5. Base, downside, and upside value ranges with explicit assumptions and no false precision. 6. A reconciliation explaining the weight assigned to each method. 7. Recommended pricing and sale-positioning options, likely buyer questions, and pre-market diligence. 8. A one-page client discussion brief. Show formulas and units. The licensed listing broker owns the opinion, method weighting, pricing recommendation, and client communication. Do not present the output as an appraisal or circulate it without the broker’s review.
