Tenant Rights When Rental Apartment is Sold
When a landlord converts a rental apartment to ownership and sells it, the tenant may have a pre-emption right and a strong negotiation position.

When a landlord decides to convert a rental apartment into ownership and sell it, the tenant often has the right to purchase the apartment under the same terms agreed upon with a potential buyer. This pre-emption right gives the tenant the opportunity to consider the purchase calmly and potentially negotiate a more favorable price.
Furthermore, tenants have strong protection against eviction. A new owner typically cannot terminate the tenancy for personal use for at least three years after the sale, and in some jurisdictions (like Berlin), this protection can extend up to ten years. This provides the tenant with time to make a purchase decision without immediate pressure.
Whether buying the apartment is sensible depends on multiple factors, not just the price. The condition of the property is crucial; for example, an outdated energy efficiency rating might indicate future renovation costs that could increase living expenses. Comparing with other similar apartments in the area also helps assess if the offered price per square meter is reasonable.
If the tenant considers buying, arranging financing promptly is essential. It is often recommended to start negotiations by offering slightly below the asking price to aim for a better deal.
