The pricing mistakes that cost the most
Lesson 4 of 6 · Price it without inventing a number
1 · Learn the move · Red-team audit
Pricing errors in this business are not random. The same handful do the damage every time: an asking price from a for-sale ad counted as a sale, a per-acre figure multiplied by the assessment roll's acreage when the deed says less, a sale with road frontage used against a tract with no recorded access, a small lot's per-acre price stretched across sixty acres, a sale with a house on it, a sale from years ago, and a margin with the costs left off. A red-team prompt that names these shapes finds them in your own worksheet by line. A general 'check my pricing' comes back reassuring. The audit is the whole job: it quotes, it names the shape, it says what fixes the line. It does not hand you a corrected price, because a corrected price from the model is the mistake this area exists to stop.
Audit my pricing worksheet below against the sources. Find: asking prices used as sales, roll acreage used where the deed differs, unlike access, unlike size, improved sales, sales older than my cutoff, and missing costs. Quote each line, name the mistake, say what fixes it. Do not give me a corrected price.
2 · Your turn. You write the prompt
You priced a 60-acre tract in Wrenfield County in a hurry and the margin looks large, which is exactly what worries you. You have the worksheet, the deed, the tax statement and your sales notes. Write the prompt that attacks the worksheet before the offer goes out.
Write the prompt for this scenario as given, or swap in a real one from your own work. The score works the same either way.
Remember: the AI sees only your prompt, not this page. If the situation isn't in your prompt, it doesn't exist.
Optional. These shape the output when you run your prompt below, not your score.
