RMI Valuation can trace its roots to 1925, with the formation of Rex-McGill Investment Company in Orlando, Florida. Founded by J. Walter Rex, Charles Walton Rex Sr. and Forrest McGill, the company was created to provide real estate brokerage and property management in the emerging Central Florida market.

In 1932, Charles Walton Rex Sr. became the youngest Organization Member of the American Institute of Real Estate Appraisers, a predecessor of the Appraisal Institute, with Certificate No. 42, and became the first in a multi-generational family line of designated real estate appraisers.

In 1991, after serving as president of Rex-McGill, Inc., Charles W. (Sandy) Rex III established RMI Midwest in the Chicagoland area. Since 1995, RMI Midwest has specialized in the valuation and analysis of corridors and other railroad properties.

Today, RMI Valuation is led by Charles Sr.’s great-grandson Cameron R. Rex, MAI. The fifth generation of the Rex family to manage a real estate company stemming from Rex-McGill, Cameron and his team work to add to the Rex legacy of quality, accomplishment, and service.
