In summary how do you determine if excess land exists and then how do you handle in within the report?
Thanks to the best dang appraiser's in the country!
I sincerely appreciate your help.
You might have to provide a little more detail to get an assignment-meaningful answer, but I'll tell you how I do it:
A. Does the area in question qualify (it appears to have its own H&BU; going through all the 4-tests)?
B. Is there strong evidence supporting that someone would actually pay a excess-land premium for the property?
If yes to A & B, you likely have excess land.
"A" is the easier of the two analyses (IMO). Keep in mind that sometimes, the physical location of the existing improvements might result in a determination that splitting the existing lot is not really feasible.
"B" is a little tougher: If there is evidence that other properties in that market with a similar site-configuration as the subject have been "split", or evidence that there is a demand for sites that can be developed, then splitting the site may be the maximally productive decision and the value of that excess lot would reflect its H&BU potential (after accounting for the market reaction... if any... for the costs involved in the split).
I think excess land H&BU analysis should be broken down into 2-parts:
The first involves determining if it is legally permissible, physically possible, and financially feasible.
The second is, if the site in question passes the above tests, then is it maximally productive to actual split it out? Because as-is, that area in question has a use that is an alternative to it being developed on its own. The maximally productive question has to be convincing (not a certainty, but a likelihood) of happening for me to make that call. What I am saying is that the value, less costs, of what is carved out has to be convincingly higher than the value of that site area as yard space, or whatever else it is being used as now.
Keep this in mind: When we make a decision that a site is excess (usually that means it has a separate H&BU and is not needed to support the existing use), we are not telling the current owner to "split the lot". What we are saying is,
"If this property were put up for sale, the likely buyer would pay a higher price for the excess land over the buyer who just wants a house on a large lot. A buyer who just wants a house on a large lot will pay for a house and a larger lot. But in this case, a buyer of the subject would purchase the house and split the lot;
the value of the existing home with the site area necessary to support it + the value of the excess land is not only higher than the value of the subject with its existing improvement on the larger (not split) lot, but it is high enough to motivate a buyer to pay more than the buyer who is just looking for the house and large lot."
The higher price is paid because there exists the ability to carve-out the excess land and sell it separately at a price that is higher than the value of that area being used as part of a larger site (yard area, or whatever it might be). Not all buyers want to go through this rigamarole, but if the site-area-in-question is truly
excess, then a buyer who would go through the rigamarole is always going to pay more than the buyer who isn't willing to do it. One buyer (in our case, the likely buyer) is paying a premium for the value of the excess land and the other buyer (who just wants a house and a larger lot) isn't going to pay that premium.
The value of the excess land is usually not what it would be if it were actually split (because it isn't actually split yet).
The value of the excess land is the value it would be if split less the costs of the split and the EI a likely buyer would require to take on the project.
Scenario A: Assume the subject property is a house on a large site with no ability to split: it is worth $100.
Scenario B: Assume the subject property is a house on a smaller lot worth $90, and a vacant site (the area of the excess land) if already split is worth $30.
The value of Scenario A is $100 and the value of Scenario B is $120. That is a spread of $20. That is probably not what the excess land is worth.
The excess land is likely worth less than $20 but obviously more than zero (otherwise it wouldn't be excess). The difference between what it is worth
as-if it were split and what it is
not split but waiting to be split is the cost to split it and EI (Entrepreneurial Incentive; think of it as the payment needed by the buyer to offset the rigamarole of actually carving out the excess land).
The likely buyer, when valuing the additional price she/he is willing to pay for that excess land, is thinking
"As a house with a large lot, this place is worth $100. If I split it, the lot with the house and now smaller lot is worth $90 and that vacant site would be worth $30 for a net difference of $20 vs. the $100. But that vacant site isn't created yet; I have to pay some fees and it is going to take some time (and I may have other risks); so I'm not going to pay $20 for something that is going to cost me money and will be worth $20 afterward.
But I will pay $105 for everything; that means I'm paying $15 for the excess land ($15, because the value of the house and the now-smaller lot is $90; so I paid $90 for it and $15 for the excess land... total of $105) and once I split it; I'll get $30 for that excess land; I'll gross $15 (paid a total of $105, split and have a a house & site worth $90 and a vacant parcel I sold for $30: $120 - $105 = $15) and that will be enough to pay for the splitting fees and reward me for going through all this hassle to begin with."
That's what I say!
Good luck!
