Although I usually agree with much of what Eric Rawlings says, I don't know that separating lot cost from house value in appraisals would help much. In my county property assessments add the potential value of the land (as if it were a vacant lot) to a value of the house (as if it were an old pair of shoes) to come up with an annual assessment. This is a defacto restatement of the old saw about Location to the third degree. In boom times, this assessment policy facilitates tear downs, where larger houses, built to their maximum allowed envelope, will fatten the county troffer. Even in these fairly slow times the tear-downs continue. By what motivation would appraisers change? A better approach to getting the buildings their due would be to have an energy assessment of the house made mandatory as in the UK. A "grade" is given to every house that goes on the market. If the AIA could get this going in even one state, or by federal mandate, Realtors would begin to see the current culture change, or at least evolve slightly. As it is, you really can't "prove" that design has any value, other than in the eye of the beholder. Sad to say.
