When vacant land or vacant sites are appraised, the land is it - everything, including view, is attributable to it. Very often, especially in built up areas, the buyer for a vacant site is not the same buyer as for a house on a site.
After the house is put on the land and they are sold together, then everything contributes to the value of the whole. A lake view, for example, might contribute 100k to a vacant site as seen in the prices. But after the house is placed on the site and they are sold together, the Lake View, per other sales and market alanlsus, the Lakeview might contribute 50k or might contribute 200k. On GSE forms, there is a separate line item and UAD field for view in the SCA.
In the cost approach, there is a line for land value estimate, and the contribution of view to the land is noted there. For res lending, GSE use it stipulates that the value be based on the SCA. I bring up GSE requirements since it is such a prominent part of the res business. However, Imo the principles would apply in any market value assignment, since it is not the form but the market that demonstrates value.
