We'll lower your rent with the rent break

Are you paying too much rent? Check your rent now!

The German rent control law (Mietpreisbremse) limits the maximum rent landlords can charge in many cities and municipalities. 

Despite the law, up to 90% of new rental agreements in many cities exceed the legal rent limit. Our interactive rent check tool gives you an initial overview of whether you’re paying too much rent.

Maximum Legal Rent

Your rent must not exceed the local reference rent by more than 10%.

Rent Reduction and Refunds Possible

You can request a rent reduction and, in many cases, also reclaim rent you have overpaid in the past.

Furnished Apartments, Sublets and Shared Flats
The rent control law generally applies in these cases as well.

5 Steps to Lower Rent & Money Refund

This is how you can reduce your rent with RentAid – and get any overpaid rent back from your landlord. We’ll guide you through every step and are here to help.

Step 1: Submit an enquiry

You send us the key details about your flat and your tenancy agreement digitally.

Step 2: Have your rent checked free of charge

Our partner lawyers will check whether your rent is too high, by how much it can be reduced, and whether you are entitled to a refund.

If your case has good prospects of success, we will offer to cover the costs of the proceedings. You can then decide whether you would like to proceed with RentAid.

Step 4: Enforce the rent break

Our partner lawyers will assert your claims against the landlord and, if necessary, enforce them through the courts.
