Istanbul's War on Fake Property Listings: What Officials, Experts and Key Figures Are Saying

Istanbul's housing market has a fake-photo problem, and authorities are running out of patience. The Istanbul Chamber of Commerce's real estate working group confirmed earlier this year that duplicate, manipulated and outright stolen property images now appear in a significant share of online listings across major platforms, fuelling misleading price comparisons and eroding buyer trust at a moment when rents in districts like Kadıköy and Şişli have climbed sharply against the Turkish lira's continuing weakness.

The issue has gained urgency in 2026 for a specific reason: the government's mass urban renewal push, accelerated after the February 2023 Kahramanmaraş earthquakes, has flooded the Istanbul market with newly completed apartment blocks and government-backed social housing units through TOKİ, the Housing Development Administration. Many of these properties are being listed by multiple competing agents simultaneously, each re-using the developer's original render or the same stock photograph. The result is that a single flat in Başakşehir or Ümraniye can appear dozens of times across platforms like Sahibinden and Emlakjet, each listing carrying a different price.

What Experts and Officials Are Saying

Professionals in the sector are not speaking with one voice. Architects and urban planners affiliated with the Istanbul Technical University's urban studies faculty have argued in published commentaries that the duplicate-image problem is a symptom of a deeper structural failure: Turkey still lacks a unified, mandatory property identification system that would tie a single registered image set to a specific cadastral parcel. Without that, any agent can download a photograph from a competitor's listing and repost it legally.

The Turkish Association of Real Estate Investment Companies, known by its Turkish acronym GYODER, has called for platform-level hash-matching technology — software that compares uploaded images against a database to flag duplicates before publication. GYODER held a working session in Istanbul in March 2026, drawing representatives from major listing platforms and property developers, though no binding agreement emerged from that meeting. The association has not publicly set a deadline for voluntary compliance.

Istanbul Metropolitan Municipality, under Mayor Ekrem İmamoğlu's administration, has taken a different position. The municipality's urban transformation directorate has been pushing for mandatory watermarking of all images used in listings tied to IMM-sponsored renewal zones, particularly in high-risk earthquake districts across the European side. The directorate argues that fake or recycled images actively hinder post-earthquake rehousing by creating phantom listings that waste families' time and money. No legislation has passed yet, but IMM officials have indicated the proposal will be submitted to the city council before the end of the third quarter of 2026.

The Ground-Level Impact in Istanbul's Neighbourhoods

Walk into any real estate office along Bağdat Caddesi in Kadıköy or along Halaskargazi Caddesi in Nişantaşı and agents will describe the same frustration: clients arrive having seen a bright, spacious flat online, only to find the photograph was taken years ago, belongs to a different unit in the building, or was generated using editing software to remove damp stains or obscure a blocked view.

The distortion is measurable in price terms, even if precise figures remain contested. According to TUIK, Turkey's statistical institute, Istanbul's residential rent index rose by more than 40 percent in nominal lira terms during 2025. Against that backdrop, even a modest misrepresentation of a flat's size or condition — reinforced by a doctored or recycled photograph — can translate into tens of thousands of lira in mispriced negotiation.

Technology firms operating out of Istanbul's Maslak tech corridor, including several proptech startups that supply listing verification services to mid-sized agencies, have been quietly positioning themselves as the practical solution. Several are offering automated image-duplicate detection tools priced on a per-listing subscription model, though uptake among smaller independent agencies in outer districts like Sultangazi and Pendik remains low.

What happens next depends largely on whether GYODER's voluntary approach produces results before the IMM forces the issue through city council legislation. Real estate professionals advising buyers in the current market say the most reliable protection remains simple: demand that any agent confirm a listing image was taken at the specific property within the past 90 days, and insist on a physical visit before any deposit changes hands. For Istanbul's renters and buyers already stretched by inflation, that basic step is no longer optional — it is essential.
