Step-by-Step Guide

Know your deposit rights: maximum 3 months cold rent (Kaltmiete). Must be held in a separate interest-bearing account.

Pro tip: Landlord must return deposit within 6 months of lease end (§551 BGB). Deductions must be itemized.

Rent increases: landlord can increase up to local reference rent (Mietspiegel) with 15-month waiting period.

Pro tip: Max 20% increase over 3 years (Kappungsgrenze). In tight markets (e.g., Berlin), limit is 15%.

Nebenkostenabrechnung (utility bill): landlord must send within 12 months after the billing period ends.

Pro tip: If landlord sends Nebenkostenabrechnung late, you do NOT have to pay any additional amounts (but you keep the right to a refund).

Contest unfair increases: respond in writing within the deadline stated in the increase letter.

If disputes escalate, contact Mieterverein (tenant association) or file with Amtsgericht.
