The mechanism:\n\n- The buyer of a $1M+ custom build is paying for **design as well as construction**.\n- **Design is a credence-quality service** the buyer must select before any visible work exists ([[darby-karni-1973-credence-goods-framework]]).\n- The firm that wins this buyer is therefore **already engaged in selling intangibles** — i.e., already practicing marketing as a category.\n\nRenoMark, Houzz \"Best of\" awards, and the GuildQuality verification system all function as **credibility infrastructure** for this segment.\n\n**Confidence:** Industry-consensus.\n\n**For Candid:** Design-build / custom-residential is the highest-fit Candid segment within the GC vertical because the buyer is already trained on credence-good selection (their own customers are). The friction of marketing-services-as-credence-good ([[marketing-services-as-credence-good-for-gc]]) is partly pre-defeated.
