Does an easement lower property value?

Appraisers do not apply a fixed percentage for easements. They value the property as if unencumbered, then value it as encumbered, and the difference is the effect. That before-and-after method is why two lots with the same easement width can show very different results.

What drives the number is how much use the easement actually takes away. A corridor that crosses the only place a garage could go, or that removes subdivision potential, hurts. A strip under an existing lawn that nobody would ever build on hurts far less.

Perception matters too, especially with overhead transmission lines, and it shows up as longer marketing time as much as a lower price. Local comparable sales that include similar corridors are the honest way to size that, rather than a rule of thumb from an internet forum.

What this looks like in practice

The honest answer to a homeowner asking this is that the easement itself is not the variable — the lost use is. A ten-foot strip under a lawn nobody would build on reads to the market as nothing. The same ten feet crossing the only flat area where a shop could go removes a use buyers were willing to pay for, and that is where the loss appears.

Sellers are often surprised to learn that disclosure helps here. A recorded easement with a clear description, a known holder and a written maintenance arrangement scares buyers far less than a vague reference and a shrug, because uncertainty is priced more harshly than a defined restriction.
