ZAC Ryan Appraisal Services, Inc.

ZAC Ryan Appraisal Services, Inc., a for-profit real estate appraisal and expert witness services provider headquartered in Green Cove Springs, Florida, operates exclusively as a prime contractor to the Internal Revenue Service, competing in full-and-open procurements with no set-aside designations. The vendor has received 51 prime federal contract awards since 2009, with combined potential value of $6 million and $4 million in obligated dollars. All work is delivered under labor-hour purchase orders focused on expert witness testimony, valuation analysis, and litigation support for IRS Chief Counsel and Department of Justice Tax Division initiatives.

The vendor's service portfolio centers narrowly on syndicated conservation easement valuations, real estate appraisals, and expert witness testimony supporting federal tax administration and enforcement. Representative work includes a $279,876.50 purchase order from IRS (awarded July 2026, extending through July 2031) for expert witness services and valuation support in Atlanta, Georgia; a $236,843.10 IRS Chief Counsel award (August 2025, through August 2030) specifically for syndicated conservation easement valuations performed in Green Cove Springs, Florida; and a $222,077.95 IRS Chief Counsel modification (December 2024, through December 2029) exercising phases 3 through 5 of an existing expert witness contract. Additional recurring contracts—valued between $80 thousand and $250 thousand and spanning five to six years—address real estate evaluation disputes and conservation easement compliance matters across multiple southeastern performance locations including Florida, Georgia, South Carolina, and Tennessee.

Customer concentration is extreme and poses material recompete risk. The Internal Revenue Service accounts for 49 of 51 awards (100% coverage by count and potential value share), representing $5.6 million in combined potential value. The Department of Justice Tax Division holds one award ($419 thousand), and the Department of Agriculture Forest Service R8-Southern Region holds one award ($10 thousand). Ten awards with ultimate completion dates within the next twenty-four months carry combined potential value of $1.7 million and represent the immediate recompete exposure. Activity has declined from a peak of six awards annually in 2023 to two in 2025 and one in 2026 year-to-date, reflecting either reduced IRS demand for these specialized services or a shift in the agency's procurement patterns. The vendor competes for new orders and modifications to existing purchase orders directly with IRS Chief Counsel; no parent vehicles, GWACs, or BPAs structure the relationship. The vendor does not subcontract and has no named federal teaming relationships in the source data. PSC codes confirm the narrow service scope: 50 of 51 awards fall under "Support—Professional: Expert Witness," with one award under "Support—Professional: Real Property Appraisals."

Our appraisal firm specializes in the valuation of acreage tracts of all types and sizes. The geographic area typically covered extends throughout Florida, Georgia, and South Carolina.
