What Keystone Appraisal Company does
Keystone Appraisal Company is a privately held real estate appraisal and consulting firm incorporated on October 19, 1908, headquartered at 801 Arch Street, Suite 500, Philadelphia, Pennsylvania. The firm provides USPAP-compliant appraisal services for commercial, industrial, multifamily residential, and special-purpose properties, including office buildings, retail, mixed-use, warehouses, landfills, parking facilities, historically significant buildings, and shopping centers. It also delivers consulting engagements covering highest and best use studies, portfolio management, estate planning, financing appraisals, condemnation valuations, and acquisition/disposition advisory, with a notable specialization in environmental contamination impact analysis and stigma damages.
The firm's client base includes law firms, real estate developers, commercial lending institutions, and federal, state, city, and quasi-governmental agencies in the Tristate area (Pennsylvania, New Jersey, and Delaware). It maintains expert witness standing in U.S. District Court, U.S. Bankruptcy Courts (Eastern Districts of Pennsylvania and New Jersey), the Philadelphia Board of Revision of Taxes, and various county courts. The business is staffed by five named professionals, four of whom hold MAI and/or SRA designations from the Appraisal Institute, with the President, Harvey M. Levin, having merged his independently established practice (founded 1967) into Keystone in 1994.
The revenue model is fee-based professional services engagement on a per-assignment basis. Go-to-market is sales-led and relationship-driven, with no public pricing, no digital marketing presence beyond a LinkedIn page, and no disclosed marketing campaigns. The firm relies on its 115-year operating history, professional designations, and litigation track record to secure engagements, with no evidence of external investment, subsidiaries, partnerships, or geographic expansion beyond the Tristate area.
