Solid lesson on caliche, but I'd challenge one assumption: renegotiating from emotional attachment isn't inevitable — that's a discipline problem, not a timing problem. On dryland deals out here, I pull NRCS Web Soil Survey before I ever make an offer. It's free, covers salinity and depth-to-restrictive-layer, and has saved me multiple wasted negotiations. Full soil testing before contracting is ideal, but free data costs you nothing except time.
