The government is proceeding with the complete “mapping” of Greeks’ real estate assets through the new Property Ownership and Management Registry (MIDAS), which is expected to become operational by the end of March.

This is the new digital platform that aims to bring order to the fragmented landscape of declarations and state records, centralizing all critical information regarding the ownership and use of every property in one place, paving the way for faster property transactions, but also for comprehensive audits focusing on undeclared rental income, unreported square footage, “grey” properties and hidden exploitation.
MIDAS was at the center of discussions at the Property Owners Conference organized by POMIDA, with participation from government officials, local government representatives, the Independent Authority for Public Revenue (AADE), the Land Registry and numerous property owners from across Greece. The new digital tool was presented as one of the most significant reforms of recent years in the property sector.
In his speech, Minister of National Economy and Finance Kyriakos Pierrakakis emphasized that it represents “the most systematic recording of private real estate property use ever conducted in the country.” MIDAS, according to him, will give the state a comprehensive, digital picture of the property inventory and the actual functioning of the market, not with the aim of loading new burdens on citizens, but to be able to design fair and targeted policies — and perhaps even “to remove burdens” from owners and the market overall.
Property Ownership and Management Registry represents “breakthrough in property management”
In his statement, POMIDA president Stratos Paradias characterized MIDAS as a “breakthrough in property management,” while highlighting the challenges that accompany its implementation. The Federation has already submitted proposals and observations to AADE, requesting simplified procedures, clear guidelines and adequate transition period, so that owners are not burdened with new bureaucratic loads or fines due to technical failures.
A central issue of the conference was MIDAS’s ability to identify and correct discrepancies between state records, a chronic problem that often creates difficulties in transfers, parental gifts or rentals. Differences between Land Registry and Taxisnet data, as well as errors in surface areas or co-ownership percentages, are expected to be highlighted automatically, enabling faster correction.
At the same time, the system introduces mandatory and detailed recording of each property’s use — whether it’s a primary residence, rented, vacant, granted or commercial space. This way, the tax administration will be able to conduct targeted cross-checks, reducing errors and enhancing transparency.
Beyond control and data cross-referencing, MIDAS is expected to offer new functional capabilities for owners. These include electronic visualization of the entire property portfolio on one screen, automatic data updates after sales or inheritances, integration with lease agreements and contracts, as well as processing declarations or corrections without physical presence at services. Additionally, the Registry will be able to function as a personal digital file concentrating basic documents, permits and certificates, facilitating transfers, subsidies and banking transactions.
Despite the benefits, concerns remain. Many owners express anxiety about potential technical problems or delays that could block rentals, transfers or housing allowances. POMIDA emphasizes that the success of the project will be judged by the system’s stability and adequate citizen support.
