Napkin sketches produce three different dwellings. A permit set produces three prices.
Send every GC the same drawings, the same specs, and the same allowance list. If one bid is $180,000 lighter, it is usually missing a mechanical package, a foundation, or a finish level — not a bargain.
Compare exclusions, not just the bottom line. Site work, septic, driveway, appliance package, and permitting fees hide in the footnotes. The cheapest bid that excludes the well is not the cheapest house.
The construction loan will fund the contract you sign, not the bid you liked. Align the winning number with the appraisal and the draw schedule before you celebrate.
