A survey gives you a visual representation of your property lines and boundaries of the property. It will show if there are any structures on the property, where those structures are located in terms of your boundary lines, so you can assess if the neighbor’s fence is on your property or if an improvement on your property is encroaching onto a neighbor’s property. You will need a survey if you’re going to obtain title insurance so they can insure the title against easements and encroachments because those items cannot be discovered without performing a survey.
