Commercial real estate applies a simple grading system to assets to rate overall quality and key characteristics. Buildings are classified as A, B, or C, and that ranking is an important indicator to gauge a property’s competitive position in a marketplace and where it fits in relation to market value and rents. Class A represents the top tier in a particular market. Some of the key attributes of Class A properties include high-end construction and interior finishes, modern architectural design, state-of-the-art mechanical systems and technology, and a variety of property amenities.
