In this brief presentation, the speaker warns real‑estate companies that withholding sold property data from the Multiple Listing Service (MLS) creates “dark data.” By not feeding sold listings back into the MLS, future comparable‑sale (comp) sets become secretive, undermining market transparency and harming all participants. The speaker urges firms to at least return sold data to the MLS so that accurate, publicly available comps can be generated, emphasizing that keeping this information hidden is detrimental to the industry.
