LANDSHILOH · UNDERSTANDING ACREAGE AND PRICE PER ACRE
A land unit-price calculation changes meaning when the denominator or included cost scope changes. This page provides fictional examples for labeling those differences clearly.
Worked example: the denominator changes the interpretation
| Measure | Calculation | Meaning and limitation |
|---|---|---|
| Asking price per stated acre | $120,000 ÷ 10 acres = $12,000 | A price ratio using the stated gross area |
| Price per assumed usable acre | $120,000 ÷ 6 acres = $20,000 | A planning ratio only if that usable-area assumption is supportable |
| Partial prepared cost per assumed usable acre | ($120,000 + $30,000) ÷ 6 acres = $25,000 | Excludes every expense not included in the $30,000 scope |
These figures describe one hypothetical parcel under explicit assumptions. They are not market values, local improvement estimates or a certification of six buildable acres. The ratio changes because the question changes; label the denominator and included costs every time.
Put this subject into practice
State the numerator and denominator before comparing ratios. Explain whether price means asking price, completed transaction price or a partial prepared-cost scenario. Identify the evidence supporting the area figure.
Keep a useful-area assumption distinct from an approval. Review changes to the inputs and retain the prior calculation so the reason for a new ratio is visible. A precise result does not resolve uncertainty in the inputs.
Working record
Create a separate record for this subject so its findings are not mixed with unrelated approvals or investigations. Keep the actual source, review date and responsible person with each entry.
- Price basis
- Area definition and source
- Included costs
- Excluded costs
- Assumption and calculation date
Illustrative example
The same asking price divided by gross acres and assumed usable acres produces two different ratios. Both can be arithmetically correct while answering different questions, so the labels must remain attached.
Fictional example for explaining the process, not a listing, valuation or approval.
Can I advertise a price per buildable acre from an early concept?
Do not present a provisional layout as an established buildable area. Have the relevant evidence and wording reviewed, and label assumptions and limitations accurately.
