A walkout backing green space is worth what it is worth whether or not anybody prices it that way. That value exists in the ground and no dashboard creates it.
What a model changes is whether the schedule knows the number. Premium schedules get set at release and then survive the whole phase, because re-testing them is nobody's job.
So a hundred and thirteen lots a year go out carrying a premium-capable attribute at base price. Not discounted — never priced in the first place.
The evidence is already in your own records. These are your closings, your comparable lots, your last twelve months. We are not benchmarking you against another metro.
A hundred and thirteen lots a year carrying an attribute nobody priced, at $8,400 each. Handed to this model by the community siting quote.
Premiums set at release and carried unchanged through a phase the market re-priced underneath them.
A walkout on a green-space lot priced as a walkout. The second attribute goes free.
Where the schedule and the negotiation disagree, the negotiation wins, and nobody counts how often.
The rest of this model — the data sets it runs on, the cause split, the working behind the reference figure and a sample output — goes out by email. Two fields, nothing else.
