What spec listing actually requires
Spec home listing is different from resale.
Generalist listing agents treat a new spec home like a resale: shoot some photos, write the description, put it on MLS, hold an open house, hope for an offer. That works for a lived-in tract home. It does not work for a $1.2M East Austin spec where the buyer pool is split between owner-occupants comparing to lived-in alternatives, investors comparing to cap-rate-driven deals, and 1031 exchangers under timeline pressure.
Spec listing requires pre-construction pricing strategy, MLS launch sequencing tuned to broker-tour calendar, agent commission structure designed to draw buyer-agent attention to a brand-new product without a sales history, presale offer management while the project finishes drywall, and a price-cut decision framework that does not panic into discount territory if absorption stalls. Each of those is a separate workstream and they have to be coordinated.
