Price the work needed to make the intended use possible—not only the purchase price—and keep unresolved site conditions visible instead of turning them into false precision.
Short answer: Before buying land, create separate budget categories for records and professional review, access, clearing, grading, drainage, erosion control, site pad or building area, power, water, wastewater, communications, permits, surveys, design, testing, mobilization, restoration, and contingencies. Define each scope from parcel evidence and responsible-source questions before requesting comparable estimates; a generic per-acre or utility allowance is not a property-specific total.
