Commercial title searches are done to find any potential issues with the title.  Issues can be anything from a transfer that was recorded incorrectly, liens from previous contractors, and zoning issues for land whose usage has been changed over time.  If you don’t have one done, you risk finding out that you don’t actually own the property you purchased, or you cannot use it for the purpose you intended on.  This includes manufacturing, retail stores, farming, food, and more.
