Rental prices for commercial properties in Islamabad can vary significantly based on factors such as location, size, type of property, and specific amenities. Islamabad offers a diverse range of commercial properties for rent, including office spaces, retail outlets, and industrial spaces. Here are some approximate monthly rental ranges for different types of commercial properties in various areas of Islamabad as of my last knowledge update in September 2021. Please note that rental prices may have changed since then:
