A drawing or map showing the precise legal boundaries of a property, the location of improvements, easements, rights of way, encroachments, and other physical features.

Your lender may require you to have a survey of the property performed. This process confirms that the property's boundaries are correctly described in the purchase and sale agreement.

Also called a plot plan, the survey may show a neighbor's fence is located on the seller's property or more serious violations may be discovered. These violations must be addressed before the lender will proceed.

The buyer usually pays to have the survey done, but some cost savings may be found by requesting an "update" from the company that previously surveyed the property.
