A lease travels with the land
If a tenant is farming your ground, the lease generally survives the sale, and in most states an oral year-to-year farm lease is enforceable. That matters for timing: many states require notice to terminate a farm tenancy months before the lease year ends — Iowa requires it by 1 September, Illinois by 4 November for a year ending in February. Miss the window and the buyer inherits another full crop year. We ask about the lease early because it moves the closing date more often than title does.
