Berlin is moving toward forming its first mayor led by the socialist party Die Linke. The shift follows state elections where the party secured a victory and announced plans to pursue a coalition with the Greens and the SPD.
Die Linke Pursues Historic Coalition
Yet the incoming administration faces immediate friction. At the center of the dispute is a central campaign pledge to expropriate large real estate companies to curb soaring housing costs.
A Massive Real Estate Takeover Plan
Die Linke campaigned on a platform to seize residential portfolios from commercial landlords owning more than 3,000 apartments. According to reporting by the US, the policy would transfer roughly 240,000 units into a newly created municipal organization.

Combined with existing social housing, the move would grant the city control over 30 percent of the local rental market. Proponents argue that removing profit motives will freeze or lower rents. This would in turn exert downward pressure on the wider private sector through neighborhood-based rent index calculations.
The Battle Over Billions and Building
The party estimates the cost of compensating landlords at 10 to 17 miljard euro. Funding would come via long-term loans repaid through tenant rents.
The Berlin auditing chamber has indicated the plan is technically feasible while warning of substantial legal hurdles. Meanwhile, housing market researchers offer sharply contrasting projections.
Kholodilin cautions that such debt loads could strain city finances. He warns it could also deter private investors at a time when Berlin requires 20,000 nieuwe woningen per year.
Political Resistance Threatens Talks
Federal Chancellor Merz announced plans to block the expropriations at the federal level.

The Social Democratic Party (SPD), Die Linke’s prospective coalition partner, also opposes the measure. That opposition sets up a contentious policy battle during ongoing government formation talks.
Beyond housing policy, Die Linke has faced coalition friction regarding statements made by some supporters that critics characterize as antisemitic. Figures within the SPD and the Greens have demanded that party leadership address these expressions, prompting the party leadership to sideline several members.
Tenant Frustrations Drive Public Backing
Public support for the intervention remains strong. Berlin features a predominantly renting population, where 84 percent of residents do not own their homes.
Tenants report widespread maintenance issues with major corporate landlords like Vonovia, which manages 130,000 woningen in the city. Renters point to unresolved structural leaks, broken fire alarms, and limited corporate responsiveness as primary drivers behind the public push for municipal intervention.
Even so, the Berlin tenants’ association, the Mieterverein, has expressed skepticism regarding the feasibility of full expropriation. It suggests alternative enforcement mechanisms, such as mandating private landlords to allocate portions of their stock to social housing alongside increased enforcement against lease violations.
