A new three-part educational series from Ag Decision Maker assists landowners, producers, lenders and investors in better understanding what drives farmland values across Iowa and the Midwest.
The series, authored by Rabail Chandio, extension economist at Iowa State University, and Emily Oberbroeckling, certified general real property appraiser at People's Company, offers practical insight into the three primary appraisal approaches: income, cost and sales comparison.
“Understanding how these approaches work helps landowners, producers, lenders and investors interpret farmland markets more clearly,” the authors explained. “While individual sales provide snapshots of market activity, appraisal methods help explain the broader economic forces that shape land values.”
The income approach: earnings and land value
The first article in the series focuses on the income approach, which links farmland value to its ability to generate revenue over time.
According to the authors, the approach helps explain why land sells for a given price by evaluating expected earnings from cash rent, crop production or appreciation, and comparing those returns to alternative investments. Factors such as interest rates, grain prices, crop insurance guarantees and investor demand all influence these expectations.
“The income approach remains one of the most useful tools for interpreting farmland values because it directly connects price to earning power, risk and long-term economic expectations,” the authors noted. “However, it also has limitations. The approach is sensitive to small adjustments in discount rates or rental assumptions, and its accuracy depends on reliable, localized data.”
The cost approach: investment and land value
The second article examines the cost approach, which addresses what it would cost to recreate a property today, separating the value of the land from the value of improvements, and measuring how construction costs and depreciation affect the overall market value.
