Iowa’s average cash rent for corn and soybean ground fell by a single dollar this year, from $271 per acre in 2025 to $270 in 2026, a decline of 0.4%. Crop prices fell by considerably more than that. Input costs didn’t fall at all.

Tanner Winterhof has watched that gap from both sides of the desk. He spent 15 years in agricultural lending, working up from loan officer to commercial banker and carrying a portfolio in the $60 to $80 million range, before going full time into Farm4Profit Media, the Slater, Iowa company he co-founded and now leads as CEO. The podcast he co-hosts has published more than 650 episodes, been consumed over 7 million times, and built an audience of more than half a million farmers. Its subject is narrower than most farm programming: whether the operation clears a profit.

Cash rent is the fastest line between farmland values and farm profitability

One sale in the neighborhood changes the conversation at every kitchen table within a few miles. Winterhof has watched ground trade at $15,000 to $20,000 an acre and seen nearby landowners start recalculating what their own acres ought to be earning.

“Landlords want a return on their investment,” Winterhof said. “If they pay a lot for the ground, or see others paying that, then typically there is an ask to raise the rent.”

“If rent goes from $300 to $400 an acre, that’s another $100 per acre the farmer has to generate through yield, price, or reduced costs before making the same profit,” he said. “Under a cash lease, the tenant bears the production, price, and cost risk. That’s especially relevant right now.”

The land market hasn’t cooled to match. Nonirrigated cropland values across the Federal Reserve’s farm-belt districts rose about 2.5% year over year in the second quarter of 2026 and remain more than 50% above their 2020 level. USDA’s Economic Research Service forecasts farm sector working capital down 9.2% this year, with net farm income at $153.4 billion, off 0.7% in nominal dollars.

The cash-in-the-door number reads better than the headline one. Net cash farm income is forecast at $158.5 billion, up 3.0%. The 2026 problem is less about revenue collapsing than about the cost of controlling ground holding firm while the cushion behind it thins.

Why farmland values and farm income stopped moving together

Midwest cropland went from $1,246 an acre in 1997 to $6,590 in 2024, according to Farmland at a Crossroads, an issue brief from CSG Midwest, a nonpartisan association of state officials. Net farm income across those same years grew far more modestly, and the brief treats that divergence as its central problem: ground priced on something other than what the ground earns.

Ownership is aging in place at the same time. In Iowa, more than 3 million acres, roughly 13% of the state’s farmland, belongs to women over 80. Citing American Farmland Trust, the CSG brief projects that 371 million acres, 41% of U.S. farmland, will change hands by 2035. Very little of it has moved so far.

Property tax assessments follow farmland values up more readily than down

“Land ownership and property taxes are relatively inexpensive compared to the overall cost of farming,” Winterhof said. “Anytime land price goes up there’s an opportunity for them to adjust the value of my asset and adjust the tax. Rarely does an assessor lower your tax when land values go back down.”

A sale price and a tax bill aren’t the same number. In most states, qualifying farmland is assessed on its agricultural use value, set by the state on productivity rather than by local market conditions, which is why a spike in what ground trades for doesn’t pass straight through to an assessment. The loose coupling cuts both ways. It buffers an operator when the market runs hot, and it gives an assessor little reason to move quickly once the market turns.

Ag lending, collateral, and access to farmland

Higher land values improve a balance sheet on paper and make lenders more careful in practice. Nearly 30% of farm lenders in the St. Louis Federal Reserve District reported collateral requirements higher than a year earlier in that same Kansas City Fed survey, and about 20% did across the other farm-belt districts. For an operator who has already borrowed against ground to fund a crop, a tighter collateral standard narrows the room available for the next operating note.

What the arithmetic tells an operator to do

Asked what the industry should want from the land market, Winterhof argued for predictability over any particular direction.

“Producers and farmland owners should root for a more stable trading relationship because that should bring stability and predictability to the land market,” he said.

He has also run the market math on narrowing the pool of buyers, and the conclusion is a lender’s. “If you limit the amount of people who could participate in purchasing land, if you’re not going to materially farm this farm ground, you eliminate a lot of wealth generation for most of the U.S. Farmers are a small portion of the population,” he said.

Predictability isn’t something a tenant can wait around for, and Winterhof’s own arithmetic points at what can be done in the meantime. The number that decides a cash lease is the one from his example: the additional yield, price, or cost reduction required to cover every extra dollar of rent before the operation earns what it earned last year. An operator who can state that figure before signing has a basis for negotiating the rent, a flex clause, or a walk-away. One who can’t is accepting a landlord’s read of the land market as a cost of doing business. Iowa’s average rent moved a dollar this year while working capital is forecast to fall 9.2%. Closing that distance is the year’s work.
