Experts say data plays a central role in raising standards across the real estate sector. Nationwide data harmonization is expected to significantly improve regulators’ ability to oversee land-use rights, project approvals, ownership records, and transaction activity.

For years, property research firms have struggled to maintain consistent datasets across cities/provinces, as fragmented information has undermined the aggregation, comparison and assessment of market trends.

A centralized national database - covering land plots, apartments, transaction prices, ownership history and legal status - would create a unified foundation, narrow information gaps between central and local authorities, and enhance real-time market monitoring.

At a macro level, analysts see this as a reconfiguration of the market toward a data-driven model, replacing practices long shaped by personal networks, intermediaries and informal information flows.

Curbing speculation and reshaping market behavior

Matthew Powell, director of Savills Hanoi, said one of the market’s long-standing problems has been the under-reporting of transaction values to reduce tax liabilities. Once all transactions are registered and fully recorded in the national system, regulators would be better positioned to track actual transfer prices, limiting tax losses and improving policy fairness.

From a policy perspective, standardized data is also a prerequisite for building land price frameworks that better reflect market conditions. Property analyst Nguyen Hoang said access to verified transaction data by location and asset type would reduce estimation bias and narrow the lag between official prices and market realities - a key objective under Vietnam’s amended Land Law, which requires land prices to align more closely with market values.

Developers also stand to benefit. A representative of a major Ho Chi Minh City-based developer said transparent data would allow companies to forecast land costs more accurately at the project preparation stage. With pricing frameworks and transaction data publicly available, firms can develop more realistic financial models and reduce implementation risks.

Information asymmetry has long been fertile ground for short-term speculation. When planning information, legal status and transaction prices are opaque, price surges driven by rumors can emerge easily, shifting risk to end buyers.

Powell said that once transaction histories and legal status are standardized, buyers can benchmark asset values using real data rather than speculative expectations. This could reduce sentiment-driven price volatility and encourage longer-term investment decisions.

In capital markets, transparent data is also expected to help lenders manage risks more effectively. Nguyen Hoang said banks would be able to strengthen credit assessments by accessing transaction histories and legal records through unique asset identifiers, reducing the risk of bad debts linked to opaque collateral.

Digital records and implementation challenges

Assigning a unique identification code to each property is akin to issuing a “digital identity card” for every asset. Each land plot, apartment or building would be linked to a single code integrating planning details, ownership rights, transaction history and financial obligations.

Over the long term, this system could be particularly significant for the secondary market, where transparency around ownership history and legal status is a key determinant of asset value. Urban homebuyers, who often face risks stemming from incomplete information, would be able to review a property’s full “profile” before making a purchase.

For institutional investors and foreign funds, an interoperable identification system could enhance the credibility of Vietnam’s property market. An investment advisory firm said standardized, transparent data would significantly reduce transaction and due-diligence costs, improving the market’s overall attractiveness.

Despite the positive outlook, building and operating a national real estate database presents challenges.

One is ensuring consistency across localities, especially as historical data remains fragmented and incompletely digitized. Another is balancing data security and privacy with the level of transparency required for an efficient market.

A digital transformation expert said the system’s success would depend not only on technology but also on enforcement discipline. If data updates are infrequent, or if discrepancies persist between registered and actual transactions, the transparency gains would be diluted.

Coordination among tax authorities, natural resources and environment agencies, construction regulators and the banking system will also be essential to ensure interoperability and avoid the siloed data structures of the past.

Real estate is not only an investment channel but also a source of housing for millions of households. As such, a transparent, data-driven market serves not only regulatory and fiscal objectives but also broader goals of fairness and social stability.

Over the long term, integrating data and assigning unique property identifiers is expected to encourage a shift from short-term speculation toward value-based investment - moving the market from one driven by rumors to one anchored in data.
