the steps to lower rent in Berlin and Hannover

Your resolution for 2026: Stop throwing money out the window on an overpriced rent!

Tenants are often not even aware that they pay several hundred euros per month too much for their apartment.

For most apartments in German big cities the base rent is legally limited.

As a tenant you can have your rent lowered during the tenancy. Has your tenancy been running for less than 30 months? Then we can not only lower the rent for the future but also claim back overpaid rent for you.

Your advantage as a tenant with us: Fair rent and fair rent reduction



Fair terms: Unlike other providers we do not only reduce your future rent. You also receive the majority of the overpaid cold rent paid up to the reduction back. Our transparent fair formula is "38%MAX": Of the cold rent reclaimed from the landlord we keep only 38% (incl. VAT) as a success fee. Because it's your rent. If we fail, you bear no cost risk.

If you unexpectedly find a cheaper rent-reduction offer with a lower success fee from another authorised legal service provider within 2 weeks after signing with us, you will only pay the lower fee.


Legal insurance: As an alternative to a success fee we can handle your case via your legal expenses insurance. If your insurer agrees to cover costs, our partner lawyers will complete the case — you won't owe a success fee. Again, you bear no risk.

No stress: We take care of all communication with your landlord. In many cases landlords agree to a rent reduction quickly when they hear from us.

Personal contact: We are personally there for you from the start. No mass procedures – every individual case matters to us.

Our daily mission since 2022: Expose rent sharks and make housing in Berlin affordable again. Because against rent sharks you need an Orca!



We are a high-impact, Berlin-based team of passionate tenancy law experts and analysts.

Become an Orca too — YOU!

The Orcas were founded by Dr. jur. Raphael Hoffmann.

Raphael is a native Berliner and grew up in Hermsdorf — at a time when "the world was still in order". Nowadays even here, at the edge of Berlin, rents have exploded.

His legal career brought Raphael to the idea of opposing this injustice. In his second home South Africa he got to know the Orcas (killer whales) and their dietary preferences. Back in Berlin's shark tank he founded: the Mietorcas.


"Not applying rent control is like throwing money out the window. Better to take more holidays than pay hundreds of euros unnecessarily each month to the landlord!"

Managing Director and Mietorca
