Are you trying to value the farmland or the partnership? The reason I ask is the partnership may have more or less value than the farmland. If it is a straight partnership (similar to stocks, bonds, REIT) where none of the partners has contributed anything other than their original investment, valuing the land and trying to decide the appropriate discount is the way to go. However, if one of the partners has contributed time, equipment, storage, etc. while the others have sat back and shared the benefits equally, the discount may need to be adjusted either positively or negatively to compensate/off set these differences.
Several other things to keep in mind, some of which should be included in the discussion regarding the appropriate discount:
- If offered for sale to the general public most likely you will pay some sort of commission to list the property or if you go the FSBO route the buyer may have a buyer's agent who will figure their commission into the offer.
- You are offering the partner a buyout. No marketing time, no holding/carrying expenses waiting for the property to sell. In your appraisal from two years ago what was the marketing/exposure time estimate?
- I am assuming you are offering a cash out vs. an installment sale. Many times in my area farmland will initially sell using a land contact or a seller's mortgage.
- You are offering your partner the liquidity of cash.
- How are crops that are either in the ground or in storage being handled?
- What is the cost of money for the purchasing partners? Do you have to liquidate investments or borrow to complete the buyout?
- Is the selling partner wanting to walk away free and clear? Might you offer them one of the parcels of land as a partial payment and let them sell it (all expenses being theirs) for whatever they can get for it and then cashing them out of the remaining parcels, possibly at a smaller discount.
- Then there is the all important PITA factor, which may negate everything else just to get the deal finalized.
Your situation is really not a great deal different than those encountered in valuing real estate. You have a buyer and seller and each has their own motivation and their own idea of value. The problem is to arrive at a point (a meeting of the minds) where no one may be completely happy but all can agree that it is the best solution for all involved. For years when doing divorce appraisals I have said, if I can upset both sides my value is probably about where it should be.
Good Luck
