Land Brokerage Services Experts Exemplify a Record Year at Colliers in Idaho

John Starr and Jimmy Roumanis represented Buyers and Sellers in a long list of notable transactions in 2021

Development land in the Treasure Valley is among the most sought-after land in Idaho. On Dec 9, Colliers land brokerage services experts John Starr and Jimmy Roumanis closed on one of their larger Canyon County transactions in 2021 with their long-time friend and partner, LDK Ventures. Starr and Roumanis worked successfully with the listing agent, who had corralled three large land owners in the neighborhood, and highlighted this superior industrial site opportunity in the North Nampa Market.

“Representing the Buyer on this 140-acre industrial park site acquisition resulted in a very long transaction time and numerous due diligence obstacles. So much of our effort is put into every transaction and we utilize our strong skillsets to benefit our clients.” – John Starr

Additionally, Starr and Roumanis recently closed on 13+ acres of residential development land offered by the Boise School District in Southwest Boise in October priced at over $6M; which will be developed as a medium-density residential site.  The call for offers process proved competitive against a brokerage competitor; however, Starr and Roumanis earned the win by positioning the Buyer, AMH, with the correct terms to close the deal.

The M2 Land sales were also among the notable transactions this year, which included The Armory in Boise and the Super Walmart Multifamily site in Northwest Meridian. Starr and Roumanis’ 16-year relationship with the developer allowed them to create a transaction where an $18 million deal was struck on a Saturday and closed 4 days later on a Wednesday.  Their tenure within the industry and established relationships enable them to identify appropriate buyers and establish the trust to complete a quick close.

“Every transaction is difficult and takes a lot of work. Jimmy and I are constantly communicating with developers and land owners to introduce them to new opportunities.” – John Starr

Another significant transaction for the Land Brokerage Services experts was the Pleasant Valley 520 property.  Starr and Roumanis initially introduced the listing to Ball Ventures and negotiated the initial land sale. The Pleasant Valley Industrial Park, to be developed on the property, will be a joint venture executed by Idaho-based Adler Industrial, Ball Ventures Ahlquist, Ball Ventures and Sawtooth Investment Management, resulting in a 360-acre regional industrial park. Starr and Roumanis were also integral in introducing Adler Industrial and Ball Ventures making this acquisition a success. This acquisition adds to a long and growing list of successful deals made by our Land Brokerage Services experts at Colliers.

“Colliers is very proud and excited for our Land Brokerage Services experts and all of their successes. I look forward to the continued growth and those benefiting from John and Jimmy’s years of experience and leadership in the market.” – Jim Shipman, Managing Owner

Colliers experts, Starr and Roumanis, possess the appropriate skillset to understand large projects and approach these transactions with acute and consistent knowledge that allows the buyers and sellers to feel at ease throughout the process.  They have represented prominent developers in a combined total of ±360 acres across 12 property listings within the last 6 months, with no sight of slowing down.
