Lilli from Hamburg cut her rent by €150 a month
Lilli thought it over carefully before deciding to apply the rent control with CONNY – and it worked. Her worry that she might run into trouble with her landlord proved unfounded. She tells her story here to show tenants across Hamburg how simple it can be to lower your rent with the rent control (Mietpreisbremse).
What Hamburg tenants should know about the rent control
The rent control (§ 556d BGB) applies in Hamburg to tenancy agreements signed on or after 11 July 2018. It covers the whole of Hamburg, so every district of the city.
If your net cold rent is more than 10 per cent above the local comparable rent (ortsübliche Vergleichsmiete), you can apply the rent control to your flat in Hamburg. Currently 66.5% of tenants in Hamburg pay too much rent. Yet according to a study commissioned by the City of Hamburg, only 1% of Hamburg tenants make use of the rent control.

“Thanks to the rent control, which the courts have upheld, Hamburg tenants have the chance to take action against excessive rents. On average they can save €276.”

Our interview with Lilli
What brought you to the Hanseatic city of Hamburg?
I was actually born in Hamburg but grew up in Munich. Then I studied media studies in Weimar. In 2018 I came to Hamburg for an internship and found a room in a shared flat. When I started my master's there, I wanted to find a flat of my own.
Hamburg is notorious when it comes to flat-hunting. How did your search go?
I searched forever – on Immoscout, but also in Facebook groups. For several months I viewed three or four flats a week. At viewings the queue stretched out onto the street. Several times I thought I must have got it, but I always came away empty-handed.
How did you get your current flat?
I was at a viewing in Barmbek. I was turned down there too at first, but the property management said they still had a flat free in the building next door. It badly needed renovating, but if I was prepared to take that on, I could move in. And then I got the flat.
What was the flat like?
Two rooms, 45 m² in total. The flat was in a really dated condition. The previous tenants had lived there for decades – and you could tell. Faded wallpaper, ancient, oddly turquoise doors and an ugly lino floor. So I renovated: tore out the wallpaper, painted, varnished the doors, had the floorboards sanded and laid a new floor in the kitchen. All in all the flat cost €543 cold. After the long search and the prices I had already seen, that didn't shock me at first.
"I got talking to a neighbour who had moved in two years before me. It turned out she was paying €200 less."
How did you realise the flat was too expensive?
At some point I got talking to a neighbour who had moved in two years before me. It turned out she was paying €200 less – and her flat had been in far better condition than mine from the start.
Did you decide to do something about it then?
I was completely torn. I had agreed to the flat at that price, after all, but I also found it really unfair that landlords can get away with that.
And how did CONNY come into it?
Right at that moment I saw a CONNY ad on Facebook and entered my details into the rent calculator. Some of them were estimates, because I hadn't been given an energy certificate by the property management, for example. In any case, the calculator told me I was paying €150 too much rent.
And then you were determined to lower your rent?
At first I still wrestled with it – for months. I was also a bit afraid of putting at risk the flat I had worked so hard to find. I thought landlords make tenants' lives hell if they rebel. On the other hand, I didn't want to go along with this upward spiral that keeps driving rents higher and higher. In the end my gut won: nothing ventured, nothing gained, and I instructed CONNY.
And did your fears come true?
No, that was the crazy thing. It took less than a week and the property management lowered the rent by €150, along with an apology. I found that unbelievable and thought: I should have done this sooner. CONNY has given me €150 every month – that sounds like something out of a spam email (laughs).
When a reduction succeeds, CONNY receives five times one month's saving – how do you rate that fee?
I think the fee is entirely fair. After all, CONNY handled the whole process for me and advised me over the phone several times beforehand. When I told my father, he said with a half-smile that you had earned very easy money with me – but there are more complex cases and less complex ones.
What could CONNY do better?
For me it simply went perfectly; it was a great feeling not having to deal with anything. And the support before and during the process was excellent and gave me a good feeling throughout.
What are you doing with the money you save?
My parents are still supporting me financially during my studies. Thanks to CONNY they now need to transfer €150 less a month. That makes me really happy.
