Coverage is another issue with portal-dependent search. The same Ministry of Housing analysis cited in Spanish media said portal datasets do not capture the full market picture, while official sources often arrive with time lags. That leaves buyers stuck between two imperfect choices: fast but noisy portal data, or slower official data. In practical terms, many buyers are making significant decisions with only part of the map in front of them.
What Portal Data Does Not Show
The missing portion is not trivial. Off-market properties — homes sold through agent networks, private introductions, or developer relationships before they appear publicly — can represent a meaningful share of premium transactions in coastal areas. Buyers who only search public portals never see these opportunities at all. The asking-price distortion problem compounds this, because even the listings that do appear may be priced against a reference point that does not reflect actual transaction data.
The Advantage of a Wider Search
Verida has a strong answer to that problem because its current positioning is not limited to public portals. The platform says Billy searches thousands of public and off-market listings, then prepares a more relevant shortlist based on the buyer's profile. That is a compelling narrative: if the market is fragmented, the real advantage is not just finding more listings, but finding the listings that buyers would otherwise miss entirely.
