Right off the bat I'm saying this is not the HBU... I then explain why I'm approaching this (2) parcel property the way I am. Evidence of owner's encumbering an additional lot for privacy despite HBU saying develop/sell/rent/what have you. Then providing market evidence of buyers who have made offers and want to keep the additional parcel undeveloped for privacy. Hence the rationale for using the HC that they are merged as one. If the properties were merged, the appraisal would be AS IS and disclosing the same issue, NOT HBU, and informing about excess land. Lastly, giving value to the additional lot in terms of additional site size only, might as well not even include as it's impact on value is minimal in that regard, especially at $.050 per SF which can be typical in my area for "in town" land.
