As we move into the first quarter of 2026, the Andalusian real estate landscape has undergone its most significant legislative transformation in decades. The approval of Law 5/2025, of December 16, of Housing of Andalusia, combined with pivotal tax amendments enacted in the 2026 Budget, marks a new era for property investment and brokerage in the region.
For professionals operating in the luxury hubs of Marbella and the Costa del Sol, understanding these changes is essential for advising high-net-worth clients and optimizing investment strategies.
The most immediate impact for investors comes from the amendment to the Property Transfer Tax (ITP) and Stamp Duty (AJD), which officially entered into force on January 1, 2026. This measure specifically targets the “flipping” strategy—purchasing properties for quick resale.
Valuation Cap: The reduced tax rate of 2% for real estate professionals is now strictly limited to properties with a purchase value (including annexes) not exceeding €500,000.
Reduced Resale Window: To benefit from this reduced rate, professionals must now resell the property within 2 years, a significant reduction from the previous 5-year window.
For the Marbella luxury market, where many acquisitions exceed the €500,000 threshold, investors must now account for standard tax rates in their profitability models, as the volume-based luxury sector will no longer qualify for this specific reduction.
In a move to professionalize the sector and increase consumer protection, the Law has created the Registry of Specialized Real Estate Agents of the Residential Sector of Andalusia.
Mandatory Enrollment: Registration is now a legal requirement to operate within the community.
Compliance: Agents must demonstrate professional qualification, civil liability insurance, and a clean criminal record related to the industry.
Transparency: The registry is public, allowing clients to verify the standing and solvency of their representatives.
The Law replaces obsolete regulations to provide a more flexible framework for protected housing. A key takeaway for developers is the simplification of administrative procedures, moving toward a “Responsible Declaration” model that covers 90% of the steps previously required, thereby accelerating development timelines.
Recognizing modern lifestyle trends, the legislation officially defines and regulates new residential typologies such as Cohousing, Coliving, and Flex-living. These are characterized by private living units paired with extensive professional services and communal spaces—a sector seeing rapid growth in the high-end Mediterranean market.
The “Book of the Building” and the “User Manual” are now mandatory for new builds and integral rehabilitations. There is a clear mandate toward near-zero energy consumption and the integration of renewable energy, such as photovoltaic systems, aligning Andalusia with the European “Green Deal“.
