A Survey is the plot/geographical area of a property that outlines and defines its proper borders and boundaries, the land the property sits on, subsurface improvements, and any restrictions or conditions that are applicable to the legal description of the property.
It is extremely important to obtain an accurate Survey as you want to ensure the property you are buying is properly defined and there are no unexpected surprises later, i.e., incorrect fence line, city encroachments, unidentified power lines and many more.
Could you imagine buying a property only to find out after closing that a portion of the backyard belongs to a neighbor?
