Land Surveying questions, answered by experts

If a buyer pays for a survey, the surveyor they hired will only provide results to them. It’s up to the buyer whether they share the survey results with the seller or not, even if they ultimately walk away from the deal. It’s considered good faith to share the results with the seller, though, especially if you back out of the deal, as the seller can then provide that survey to future interested parties.

Professional well contractors may use electromagnetic mapping to look for places with a high likelihood of water. Water access can vary significantly, even on the same property, so it can be difficult to know where to drill if you don’t have specialized tools to look for water.

Property lines, building locations, and potential encroachments are mapped.

Professionals who complete perc tests can usually do them in a single day. Including excavating to expose the test site, filling the hole with water, and monitoring it while it drains, you can expect the test to take between four and eight hours total. It’s possible that you’ll get the results the same day, but some companies may take a few days to get official results.

A few different types of land surveys can help determine certain features and boundaries of your property. These include:

  • Boundary surveys describe the actual borders of a property. These are generally required when trying to get construction permits issued. 

  • Location surveys provide much of the same information as a boundary survey but also include in-depth information about any improvements made to your property. 

  • Mortgage location surveys are usually required by lenders and title companies before financing or offering an insurance policy. 

  • Site-planning surveys are done before applying for building permits and can be issued before any major home improvements. 

  • Topographic surveys provide a formal map of land elevations. It can also describe the location and size of natural features and any land improvements.
