How the rent-to-price figure works
A year’s cash rent for an acre, divided by the median price an acre paid for the same kind of land in this county over the last three years: sales of a single parcel of 10 acres or more, never lots or house sites. Sales counted: Illinois transfer declarations (IDOR PTAX-203) of 10 acres or more that the parties declared as farm property, single-parcel deeds for value with none of the form’s related-party, distress or partial-interest answers checked. Where fewer than 10 such sales were recorded, or their prices range too widely, no figure is shown. A low share usually means land here is priced for something other than farming, such as homes or development.
