Had one a few years ago that wanted 2 platted 3+/- acre lots combined into one. I tried so hard to explain the fact of life to them, but they just didn't get it. The buyer wasn't yet sure where he was going to build a house on this, in the middle of these 2 parcels or maybe on the edge of the lot lines, or maybe the house on one with setbacks that would be legal and the barn on both..... The lender, that didn't understand, wanted and expected an appraisal of both combined but with the value as if they were separate.
They were worth much more individually than combined. IF I did them together, there was no way the value would be what he was paying for the 2. If I didn't explain the potential repercussion of the various scenarios of where the buildings were eventually placed, my client could have ended up with a mortgage on a combination of 2 sites that were now worth a lot less.
So I finally did a high priced narrative giving them 3 values - each lot was valued separate, then if they were actually combined into one it had a value. They REALLY didn't like the value of them combined, but I did what I believed was correct first by valuing each one individually, then gave them what they asked for.
They were confused for a while, but I kept insisting that they sit down and READ the report. They finally did that and finally understood what I did, why I did it, and that what they were asking for was not the right thing to do.
