Just don't tell.
In a moment of uncharacteristic honesty, I sat down with some colleagues to talk about cash rents. Greg Vincent captures it well. But like most loudmouths, I have twinges of regret.
My basic position is rents are similar to your operating note interest rate, or your discussions with your attorney: private. There is little upside in sharing that information other than commanding local attention for a few moments.
Moreover, such candor simply underwrites the predation of $10/acre-better renters. Nonetheless, these things seem to happen. So my current view of the problems is this:
If your relation to your landlord is based on 1) the ignorance of the landowner of current rental values, or 2) a check sent every spring/fall, THEN
You are not long for this business.
