● Security Features Score (15%) – Individual unit alarms, 24/7 video surveillance, electronic gate access, on-site managers, and insurance options (out of 15)
● Climate Control & Protection (10%) – Temperature and humidity management essential for protecting belongings during extended storage
● Contract Flexibility (10%) – Month-to-month options, no long-term commitments, transparent lease terms
