The potential environmental effects of animal feedlots, such as possible water contamination and foul odors, are a real concern for those living near one of these facilities. This field guide presents current government regulations, industry trends and studies on the impact of feedlots on surrounding property values. While most studies have found a negative relationship between feedlots and property values, a few have found a positive impact. (D. Shumaker, Senior Library Information Specialist)
What Are Animal Feedlots?
"Animal feeding operations (AFOs) are agricultural enterprises where animals are kept and raised in confined situations. AFOs congregate animals, feed, manure and urine, dead animals, and production operations on a small land area. Feed is brought to the animals rather than the animals grazing or otherwise seeking feed in pastures, fields, or on rangeland."

Effects on Real Estate
An Analyisis of the Impact of Swine CAFOs on the Value of Nearby Houses, (U of Northern Iowa, 2008). Large adverse impacts suffered by houses that are within 3 miles and directly downwind from a CAFO are found. Beyond three miles, CAFOs have a generally decreasing adverse impact on house prices as distance to the CAFO increases. [opens as a Word Doc File]
Animal Feeding Operations and Residential Land Value, (University of Missouri Extension, July 2006). Summary of literature on the impact of AFOs on land values. All studies indicated that the impact of AFOs on property value was localized or limited to properties near the AFO. Most studies found a negative impact though a few found either a positive or no impact. [links to PDF]
Evaluating the Effect of Proximity to Hog Farms on Residential Property Values: A GIS-Based Hedonic Price Model Approach, (URISA Journal, 2005). This study finds a negative and significant impact on property value from hog operations. [links to PDF]
Living with Hogs in Iowa: The Impact of Livestock Facilities on Rural Residential Property Values, (Iowa State University, Center for Agricultural and Rural Development, Aug. 2003). This study finds that livestock operations have an overall statistically significant effect on property values. Predicted negative effects are largest for properties that are downwind and close to livestock operations. [links to PDF]
Concentrated Animal Feeding Operations and Proximate Property Values, (The Appraisal Journal, July 2001). Property located near a concentrated animal feeding operation (CAFO) will be negatively impacted by this externality. The degree of impairment depends on proximity and property type and use. Properties with higher unimpaired values are probably impacted more than otherwise lower-valued properties. Q
