Santiago Battles Fake Property Listings More Successfully Than Bogotá

Chile's Servicio Nacional del Consumidor issued a formal directive in May 2026 requiring the country's five largest property listing platforms to deploy automated image-matching technology by September 30, or face fines of up to 300 UF per infraction. The directive targets duplicate property images, a practice where landlords and brokers post identical photos across multiple listings, often at different prices, to flood search results and manipulate perceived demand.

It is a problem that looks mundane until you are hunting for a two-bedroom apartment in Ñuñoa and realise the same sun-drenched living room photo has appeared in seven different ads, attached to seven different addresses, at prices ranging from 450,000 to 680,000 pesos per month.

Why This Matters in Santiago Right Now

The timing is not accidental. Santiago's rental market has tightened sharply over the past three years as Venezuelan and Haitian migration accelerated demand, particularly in communes like Estación Central and Independencia. The municipality of Santiago Centro logged a 34 percent rise in formal rental complaints to SERNAC between 2023 and 2025, according to figures the agency published in its annual consumer report last December. Duplicate listings inflate apparent scarcity, push prices upward, and expose newly arrived migrants, who often cannot visit properties in person before signing a lease, to outright fraud.

Portal Inmobiliario, the country's dominant listings site, confirmed in a June 2026 statement on its platform blog that it had already begun a phased rollout of perceptual hash technology, a system that detects visually identical or near-identical images, across its database of more than 180,000 active listings. Toctoc.com, its main competitor, announced a similar pilot in April covering listings in the Metropolitana region.

The question for regulators and renters is whether Santiago is moving fast enough, and whether the tools being deployed here are comparable to what renters in other major cities can already count on.

How Santiago Compares to Bogotá and Barcelona

Bogotá's Secretaría Distrital del Hábitat launched a centralised rental registry in 2023 that requires landlords to upload a unique cadastral code alongside any listing photo, effectively preventing the same image from appearing under more than one registered address. The system, built into the city's MetroVivienda platform, has no direct equivalent in Santiago, where cadastral data and listing platforms remain siloed.

Barcelona's Agència de l'Habitatge de Catalunya went further in January 2025, mandating that all short-term and long-term rental ads carry a verified licence number that links back to a single canonical property record, and suspending listings automatically if image duplication is detected across platforms. Landlords there face suspension from all regulated platforms, not just fines.

Santiago's approach, by contrast, relies on the platforms policing themselves under the threat of SERNAC penalties, with no cross-platform data sharing requirement. A renter who spots the same bathroom photo on both Portal Inmobiliario and Toctoc.com has no single authority to report it to who can act across both sites simultaneously.

The Cámara Chilena de la Construcción has supported the SERNAC directive in principle, but industry representatives have noted, without disputing the need for the rule, that small brokers operating in communes like La Florida and Puente Alto, who list properties on WhatsApp groups and Facebook Marketplace rather than regulated platforms, fall entirely outside its scope. Those informal channels, which handle an estimated significant share of rentals in the outer communes, are not addressed by the September deadline.

For renters, the practical advice from consumer advocates at ONG FOCO Ciudadano is straightforward: use Google's reverse image search on any listing photo before paying a deposit, cross-reference the listed address against the Conservador de Bienes Raíces database at conservador.cl to confirm the owner's identity, and report suspected duplicates directly to SERNAC via its online complaint portal. The September 30 compliance deadline gives the major platforms roughly 90 days to clean up their databases, after that, enforcement will show whether Chile's rules have teeth or just intent.
