The goal is that as a tenant you make informed decisions, meet deadlines and secure evidence correctly to strengthen your position in rent negotiations and in case of termination or eviction. Read on for concrete sample clauses and negotiation strategies.

What is all-in rent?

In an all-in rent the tenant pays a flat total amount that often includes ancillary costs. Such clauses are only effective if clearly formulated and the included services are transparently listed. Legal bases can be found in the BGB.[1] In interpretation questions BGH decisions play a role.[3]

In most regions tenants are entitled to basic habitability standards.

What tenants should check

  • Check which ancillary costs are included in the all-in rent.
  • Request a breakdown of the flat fee and supporting documents for costs.
  • Pay attention to the landlord's repair obligations and report defects immediately.
  • Set reasonable deadlines for remedial work.
  • Keep payment receipts and photo records.
Keep all payment receipts organized.

Forms and templates

Important forms include the sample termination letter for tenants (for timely termination), the written defect notice for documentation and the complaint form for eviction suits. Official templates and forms are available from the justice authorities.[4] The civil procedure rules for filing a claim are set out in the ZPO.[2]

Example: For a justified rent reduction, first send a written defect notice with a deadline, document photos and invoices, and only terminate if deadlines pass without remedy.

FAQ
