South Korea

Primary housing-market rulemaking and transaction-reporting sits with the Ministry of Land, Infrastructure and Transport (MOLIT) and local governments via the Licensed Real Estate Agents Act and the Act on Report on Real Estate Transactions (incl. mandatory reporting systems). Personal-data governance is overseen by the Personal Information Protection Commission (PIPC) under the Personal Information Protection Act. Advertising and consumer-protection enforcement relevant to listings and lead-gen intersects with the Korea Fair Trade Commission (KFTC) and the Fair Labeling and Advertising Act.

For portals, the compliance perimeter is expanding from 'classifieds' into regulated workflows: (1) brokerage activities and agent conduct are governed by the Licensed Real Estate Agents Act; (2) transaction (and certain lease) reporting systems under the Real Estate Transactions framework increase scrutiny of false reporting and price manipulation; (3) PIPA enforcement raises the cost of personalization, lead routing and AI-driven profiling; and (4) deceptive claims in listing/ads can trigger Fair Labeling and Advertising Act exposure. Market shocks like jeonse fraud and recurring fake-listing incidents are driving more active supervision and higher user expectations for verification.

The recovery was highly uneven. Official REB weekly data show Seoul apartment prices rose 8.71% in 2025 (fastest in ~19 years) while many non-capital regions still declined, indicating a polarized market where 'prime Seoul' outperformed rather than a broad national boom.

Underwrite a continuing shift toward wolse (monthly rent) and higher 'trust premiums' for verified/managed properties. Policy research and market reports note jeonse has been shrinking while wolse grows, and MOLIT recognized 32,185 jeonse-fraud victims by July 2025—evidence that counterparty and priority-risk must be priced explicitly (ownership checks, lien priority, insurance/guarantees where available).

For comps, use MOLIT's Real Transaction Price Open System as the baseline, then triangulate trend direction with REB's weekly/monthly price trend surveys. For context and alternative benchmarks, bank/portal indices (e.g., KB Land) can be useful, but note that private and official indices have diverged in some historical periods—so triangulation matters.

It is material enough to trigger active enforcement: reporting cited by ChosunBiz said the land ministry flagged roughly 30% of university-area listings as suspected false or deceptive. Practical mitigations include using licensed brokers, insisting on address/registry verification, cross-checking advertised prices against real transaction databases, and favoring platforms with clear moderation and reporting processes.

Three stand out: (1) macro-prudential tightening risk (e.g., LTV cuts in wealthy Seoul districts) that can change liquidity quickly; (2) fraud-response policy (Special Act on jeonse fraud extended) that reshapes tenant protections and auction dynamics; and (3) stricter platform/data governance (PIPC enforcement and evolving online-platform competition rules) that can affect lead-gen, ranking algorithms, and AI personalization.
