Greg Eidson is a veteran of the valuation industry with more than 30 years of experience in the real property valuation, brokerage, and consulting industry. Eidson has particular appraisal experience with industrial real estate that includes heavy and light manufacturing, warehousing, distribution, and special purpose such as meat processing plants, timber processing, automotive and steel manufacturing. More general appraisal experience includes free standing and multi-tenant retail, extended-stay hotels, limited service and full service hotels, office buildings, industrial properties, special purpose properties, multi-family and self-storage facilities, residential subdivisions, conservation easements, mitigation banks, recreational and timber land, right-of-way for public and private utilities and state and local transportation clients.

Eidson's valuation opinions have been used in the context of mortgage lending, right-of-way acquisition, bankruptcy court, buy/sell decisions, purchase price allocation, loan monitoring, forced disposition, portfolio performance monitoring and litigation support.

Prior to merging his firm into GlassRatner in late 2018, Eidson ran The Eidson Company and focused his practice on conservation easements, mitigation banks, mortgage loans, right of way, and litigation support. During the 18 years that Eidson ran his own firm some of his assignments included;

  • Residual insurance valuation for a British insurance company who insured the difference between market and contract rents on properties such as Walgreens and CVS Pharmacy occupied properties.
  • Right of way valuation for the Alabama Department of Transportation, Georgia Department of Transportation, municipal utilities, the National Park Service, and the Sabal Trail Pipeline.
  • Litigation support weighted toward deposition and testimony with the Department of Transportation and also includes support for lawsuits that involved property damaged by flooding (land, residential and multifamily projects), contamination (medical waste, dry cleaning solvents), and construction defects (residential construction, office building damage, hotel water leaks, multi-family construction, industrial manufacturing construction). Eidson has testified to property taxation issues and conservation easements in Federal Tax Court.
  • Preparation of appraisals for bankruptcy and foreclosure proceedings, and, Preparation of appraisals for Mortgage loans encompasses subdivision developments, hotels, mixed use developments, retail, industrial, office, special purpose, and timber land.

In the late 1990s prior to the formation of his own firm, Eidson worked for The Highland Group Hotel Investment Advisors. This boutique style consulting firm is a specialist in the market analysis of hospitality properties. Eidson prepared valuation reports for full-service, limited-service and extended-stay properties. These reports were used for the purpose of development decisions, purchase decisions, feasibility and financing. Geographically, these hotel projects were typically located in the Midwest, East Coast and the Southern states. Eidson's tenure with The Highland Group was an excellent education in the analysis of hotel feasibility. The most valuable takeaway from this experience was gaining a greater depth of understanding in the development of demand studies.

In the late 1980s to the 1990s, Eidson worked in the Real Estate Advisory Group of American Appraisal Associates. Eidson started with American Appraisal Associates as a junior level appraiser and was the Manager of the Atlanta office of the Real Estate Advisory Group when in departed the company in the mid-1990s. During his tenure with the company Eidson prepared and managed appraisal assignments for pension funds, insurance companies, portfolio managers, lenders, attorneys and Fortune 500 companies. These valuation assignments were used for purchase price allocation, investment portfolio analysis, mortgage loans, property tax appeals, and cost segregation studies. Eidson was recognized by the company for his ability to address client needs in a timely and professional manner. The experience with American Appraisal was invaluable to my education in managing people and projects and learning to balance the expectations of our clients with the human and technological resources. Geographically, Eidson travelled throughout the United States and Caribbean and personally handled residential subdivision developments in Southern California; mixed-use high rise buildings in downtown San Francisco; high rise office buildings in Dallas, Denver, Chicago, and Boston; regional malls in Texas; movie theaters in New York; shipping facilities in Houston; industrial manufacturing and distribution buildings in states from California to Connecticut to Georgia; multi-family apartment developments in North Carolina to Florida and hotels in California and the Caribbean.
