I appreciate your insights. I'm still not certain having a set fee tied to an expandable SOW is appropriate. Period, let alone should it be an industry standard. I understand answers such as, "Orders can be rejected.", "It's a business decision.", or "Renegotiate the fee." if new circumstances arise (like a cell tower in the front yard.. yikes!). These are all true. They may not put food on your table but they are true. However, it looks to me like classic scope creep. What I don't understand is appraiser's that just suck it up and give away their time. Obviously, this sets an expectation for the next appraiser. And so on. Hence, the industry standard. Expert analysis should be compensated based on time with consideration given to the complexity of the actual project rather than based on a competing bid based on a limited amount of information. Any thoughts? Disagree? Agree... anyone?
