The Iowa REALTORS Land Institute September farmland survey released Thursday finds values for all three farmland types across all regions averaged down point-two percent in the last six months. Spokesman Elliott Siefert says that leaves values essentially flat. He says northwest Iowa was the region with the biggest drop — down two-point-nine percent and south-central was up one-point-three percent. Siefert says this is the second survey in a row with pretty flat numbers here after rising prices in the two years prior. He says the biggest headwind they’re facing is interest rates, which have risen and taken away a little bit of the buying power for land buyers.
