Nearby annoyances that could potentially lower a property's value are called?

The term that best describes nearby annoyances that could potentially lower a property's value is "detractors." Detractors refer to elements or factors that have the potential to negatively impact a property’s desirability or value. These can include things like noisy highways, unpleasant odors from nearby factories, or any other nuisances that might dissuade potential buyers or tenants.

Understanding the impact of detractors is crucial for real estate professionals, as they can significantly influence both marketability and appraisal values of properties. While "impediments," "irritants," and "disruptors" seem relevant, they do not capture the essence of factors that affect property value as effectively as the term "detractors." Detractors highlight not just an annoyance but a clear connection to the economic implications on property valuation.
