Our Take

CSSI built its reputation on traditional, boots-on-the-ground engineering studies. While thorough, this approach is overkill and cost-prohibitive for standard residential (STR/LTR) and small commercial properties. You pay for travel, site visits, and high overhead. Room42 utilizes modern data modeling and AI to deliver the same tax benefits in minutes, eliminating the need for intrusive site visits and hefty consulting fees.
