Dave you are correct.
However, can you build a pro-rata share of a building, or common area, with in a $ dollar cost, that is reflective of the market value of a unit owner's unit?
You betcha. I never said it was easy.
The unit owner owns 1/137th of the entire complex, which costs $x,zzz,zzz to build, Oh wait, doesn't that $x,zzz,zzz number exceed the license level for CRs in many states? Oh snap!
Absolutely - this is an argument I have made for decades. Obviously, I would charge more to do such an assignment than I would to appraise the project itself.
But anyway,
But anyway, the entire complex costs $x,zzz,zzz to replace (land + new cost - depreciation) and the unit owner's pro-rate share to replace via the cost approach is $xx,zzz.
and is going to depend on who owns the land, the condo association or the declarant, or some other entity.
The type of vestiture of the land in and of itself is typically irrelevant. The contributory value of the owner's interest in said land is all that matters.
But that is not a "replacement cost" for a single unit, and reflective of the market value of a single unit, to a typical single unit buyer.
It is if performed properly. Lets just go backwards for a minute - I performed a feasibility study for a high rise condo. project years ago. Much of the work involved determining costs for the project. It involved determining the aggregate costs of the project, based upon a hypothecated ideal unit mix, and the values thereof. Not particularly different than the case at hand.
