As a real estate investor, you need to know what you’re buying.
Not every office building is Class A, although some brokers tend to push listing packages, written in flowery language, exclaiming that every property they have available is the best one in its market.
Viewing the property through investment classifications can lead to more thoughtful, valuable appraisals and a more appropriate value. This is especially important in selecting a cap rate for a property.
Low–to–mid–rise office development is generally defined as having one to five stories. Location and function are of major importance to office tenants. Given the higher costs of tenant improvements and operating expenses, building management takes on a greater role, and the investor needs to be better capitalized to maintain occupancy.
The quality rating of a project indicates the competitive ability of the project to attract tenants and investors. Appraisers must be aware of how these factors affect valuations in office buildings and medical office buildings (MOBs). Presented in the following table are the general investment attributes that make up Class A, B & C office buildings. Within these classifications, there may be a few characteristics that are consistent with a Class A building, but other characteristics fall short.

Medical office space is a specialized version of office space. This segment of the market was originally oriented primarily toward owner-users but is now becoming more mainstream as an investment product. After all, medical practices are among the most financially robust tenants in the market and need to operate from a business location. A continuing trend in the market is toward group practices which are leased by credit tenants, such as hospitals or medical groups.
These buildings are generally clustered around a hospital or located near a strong demographic pool. The fact that patients will be coming to the building increases the need for a safer, more sterile environment. Medical office product requires construction that allows for extensive plumbing, numerous restrooms, elaborate cabinetry, gas availability, and tenant-specific room designs, such as those used for operations, examinations, laboratories, X-rays, etc.
Tenant mix is another important element of medical buildings. For example, dentists in general practice prefer working in buildings with other specialists they can refer patients to, such as orthodontists, oral surgeons, or periodontists.
Likewise, medical doctors prefer to be around other specialists in the medical field, such as orthopedists, radiologists, internal medicine specialists, cardiologists, and pharmacists, etc. Presented in the next table are investment classifications for medical office buildings.
