Why did my assessed value go up when I did not renovate anything?

An assessed value can rise without any renovation because South Carolina counties periodically reassess property on a set cycle, and rising sale prices for comparable homes nearby push the whole area's assessments up together. A neighbor's improvements or a broader market increase can lift an assessment even when the specific home has not changed at all. Owners who believe the new figure overstates their home's value can appeal it with the county assessor's office.
