International demand is not a side story in Spain's housing market. It is part of the structure of the market itself. Notarial data show that foreign buyers represented 18.4% of all home purchases in the second half of 2025. Registradores, using a different methodology, put the foreign-buyer share at 13.52% in Q4 2025 nationally, 12.5% in Andalusia, and 31.11% in Málaga province. A product built for Costa del Sol property search is, by definition, serving a large audience of buyers who often live abroad, compare neighbourhoods remotely, and make decisions before they have full local knowledge.
The Premium That Reveals a Product Problem
Those buyers also behave differently on price. Notarial data show that nonresident foreign buyers paid an average of €3,242 per square metre in the second half of 2025, compared with €1,963 for resident foreigners and €1,839 for Spanish buyers. That premium shows how much capital is moving through cross-border demand, but it also reveals a product gap: standard search filters are too shallow. Beds, baths, and price bands do not capture whether a buyer cares more about school access, airport friction, summer noise, walkability, renovation burden, long-term hold potential, or a calmer neighbourhood that still protects resale value.
Billy as an Intent Translator
Verida's answer to that gap is Billy. The public site already says Billy can guide buyers in their preferred language and help them clarify area, budget, lifestyle, property type, and practical priorities through conversation rather than static filtering. In the fuller product brief, Billy evolves that idea into voice-first behavioural interviewing, hidden-preference capture, and predictive lead scoring. That is exactly the right product logic for an international market.
If a buyer says they are worried about the morning drive into Marbella, want dinner on foot but not nightlife under their window, or care more about a private outdoor space than an extra bedroom, Billy can structure those signals before the shortlist is ever built. That changes the role of technology from search engine to intent translator.
