ZAC Ryan Appraisal Services, Inc.

ZAC Ryan Appraisal Services, Inc., a for-profit Florida corporation, provides expert witness services and real estate valuation support to the Internal Revenue Service as a prime contractor on full-and-open competitive purchase orders, with no subcontracting footprint. The vendor operates from Green Cove Springs, Florida and serves exclusively civilian federal customers under labor-hour pricing arrangements, with primary work falling under NAICS 611710 (Offices of Real Estate Appraisers) and PSC code Support-Professional: Expert Witness. The company competes without set-aside protection across its entire prime contract portfolio.

ZAC Ryan's customer concentration is extreme and deliberate. The Internal Revenue Service accounts for 50 of 52 prime awards and $5.8 million of the $6.2 million combined potential value (94% of awards, 94% of dollars), with ancillary engagement from the Department of Justice Tax Division ($419 thousand, one award) and the Department of Agriculture Forest Service R8-Southern Region ($10 thousand, one award). This Treasury-centric footprint has persisted across more than a decade of federal work, with the source data showing awards dating to 2009 and current performance extending through mid-2031.

Recent activity has flattened significantly. The vendor received four awards in 2022 and six in both 2023 and 2024, then dropped to two awards each in 2025 and 2026 (as of August). Nine awards carrying combined potential value of $1.5 million reach ultimate completion within the next twenty-four months, creating near-term recompete exposure. The most recent awards reflect the vendor's core capability: a $241,446 August 2026 purchase order for expert witness testimony and valuation analysis in Atlanta, Georgia (IRS); a $279,876 July 2026 award for expert witness services, also with the IRS, extending through July 2031; and a $236,843 August 2025 award for valuation and appraisal of syndicated conservation easements supporting IRS Chief Counsel, performed in Green Cove Springs. Preceding awards from 2024 and 2023 demonstrate identical scope — labor-hour expert witness services supporting IRS litigation and tax enforcement, typically valued in the $200,000 to $250,000 range per order and performed across Orange Park, Atlanta, and Nashville, Tennessee. All recent awards include FAR clause 52.222-90 implementing Executive Order 14398 compliance.

The vendor's entire award footprint centers on litigation and valuation support for federal tax administration. Work supports expert witness testimony, real estate appraisals, syndicated conservation easement valuations, and valuation analysis for IRS Chief Counsel and the Department of Justice Tax Division. No parent vehicles, IDIQs, or GWACs appear in the source; all awards are direct purchase orders issued by IRS contracting offices. Obligated dollars total $4.1 million against the $6.2 million combined potential value, indicating invoicing rates of approximately 66% against ceiling value across the active portfolio.

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.
