Rent Index Guide for Tenants in Germany
As a tenant in Germany, the rent index (Mietspiegel) is an important tool to check the local comparative rent and, if necessary, contest an excessive rent amount. This guide explains step by step how students and first-time tenants can use the rent index correctly, which official forms and deadlines to observe, and which pieces of evidence can help in court. You will learn how to check statements, question rent increases and when a rent reduction is justified. Practical examples show how to write to landlords and when the local court is competent. The aim is that you, as a tenant in Germany, can assert your rights confidently and securely. We also show how to organise documents and meet deadlines so you are prepared in case of dispute.
Understanding the Rent Index
The rent index reflects the local comparative rent and is a basis for calculations under the German Civil Code (BGB)[1]. Not every rent index is the same: the data basis, timeliness and publication format affect its reliability.
Keep all rent receipts organised and stored safely.
How to check the rent index
- Check whether an official rent index exists for your municipality and which years and apartment sizes it covers.
- Select comparable apartments by year of construction, living area and equipment.
- Calculate the local comparative rent and compare it with your current rent.
- Document discrepancies and set written deadlines for clarification.
Respond to rent increase notices within deadlines.
Forms and deadlines
There is no official statutory form for a termination letter; a proper termination follows the rules of §573 BGB[1]. For eviction or litigation processes, the Code of Civil Procedure (ZPO)[2] applies, and cases of fundamental importance are decided by the Federal Court of Justice (BGH)[3]. Practical example: send a letter to the landlord with a concrete deadline (e.g. 14 days), a justification and supporting documents by registered mail.
Reply in writing and document how you sent the correspondence.
