CSR2 is how Iowa land is valued
Corn Suitability Rating 2 indexes the productive capacity of Iowa soils, and it is the language the market speaks. Two parcels at the same price per acre with materially different CSR2 values are not comparable purchases.
Pull the CSR2 for any parcel under consideration, compare it against recent sales in the county at similar ratings, and understand that the premium for high-CSR2 ground is rational rather than sentimental — it produces more, year after year.
Drainage districts and assessment liability
Iowa's productivity rests substantially on tile drainage, much of it organised into drainage districts with authority to assess benefited land for maintenance and reconstruction. Reconstruction projects can generate assessments considerably larger than routine maintenance.
Before buying, ask the county auditor or drainage clerk whether the parcel is in a district, what current assessments are, and whether any project is pending or under consideration.
Ownership restrictions
Iowa restricts agricultural land ownership by certain corporate entities and by non-resident aliens. The rules have exceptions and have been litigated, and the practical consequence is that entity structuring for an Iowa farm purchase is a matter for a lawyer familiar with the statute rather than a generic LLC formation.
Tenants and leases
Most Iowa cropland is farmed by tenants under cash rent or crop share arrangements, and Iowa law provides tenant protections including notice requirements for lease termination that run to specific dates. A buyer may acquire land subject to a lease that cannot be terminated for the coming season.
Establish the lease terms, the termination notice status, and the current rent before closing.
