As a Tenant, you are faced with many challenges when it comes to helping your landlord and other tenants understand the impact of Functional Obsolescence on your commercial and residential properties. In this reference book, I will show you how to help your landlord see the relationship between inadequate design and the depreciation of real estate so they can make better decisions about their future investments. I further explain what these detrimental conditions are as architectural and building code issues and why it's important for Tenants to understand them. It must be said that some landlords may not want to acknowledge a problem to rectify. Therefore, I propose that the Tenant given critical reference material should provide solutions through a consulting Architect. Ultimately, I will discuss ways to identify functional obsolescence before closing on a property so that you can mitigate potential problems or even reject a negative real estate transaction altogether!
