Lee -I don't say NO for any other reason than the obvious one: In such a situation, the H&BU as improved is not as one property. This is true no matter how much you desire to lump the 2 together to offer one opinion of MV>
That is your opinion and I understand your point of view. However, the assignment is for ( even in a refinance, a presumed sale ) the house sold together with an adjacent lot. I fail to see how that diminishes the value of the house on its lot - even if appraiser determines the vacant lot value is diminished by selling it together with a house. in any case, we have to explain what the "other" alternative use is if we mark "No" - so what would it be ? No? other -sell the house without adjacent lot?
Though I understand the reasoning, now we are telling people what they can and can not do in a market, even if what they want to do is legal. There is nothing illegal about selling a house together with an adjacent vacant lot. It becomes a valuation problem to be solved if that buyer is financing. Some want to decline the assignment, which may be a good choice.
