Consumer portals commoditised the "just-sold" edge — practitioner consensus; portals cannot capture local nuances, off-market activity, or hold-offer strategies

Claim. Practitioner consensus: consumer apps have watered down the realtor competitive advantage of providing "just-sold" data. Realtors need other ways to engage clients or show value. HouseSigma pulls from MLS systems but may not capture local nuances, recent off-market activity, or AI-uncapturable seller strategies like holding offers.

Confidence. Industry-consensus on the commoditisation point; single-source for the specific framing.

Caveats. "Cannot capture local nuances" is the practitioner narrative; portals will continue to close the gap. The off-market-activity and hold-offer points are durable advantages because they sit outside the MLS itself.

Implication / use. Pivots the article: portals took the headline figure; the durable edge moves into the deeper structured layer and off-market network.
