Big Sioux Appraisals was founded in 2010 in Sioux Falls. Since then we have been providing quality appraisals throughout Southeastern South Dakota and Southwestern Minnesota. How do we do it? We stay current on the supply and demand within each market and constantly research and review relevant sales data, land values, and construction costs. We understand the contributing factors and nuances that influence sales prices within a particular market. We work hard to provide credible opinions of value and quality appraisals, every time.
