Your apartment building
deserves more
than administration.
OneHaven rents out your furnished apartment building faster, keeps more units leased, and helps tenants stay longer as a specialized leasing and management partner for temporary housing.
OneHaven rents out and manages furnished apartment buildings for owners and portfolio holders: entire buildings, not individual apartments.
50 to 300 units. No individual apartments, no scattered holdings.
Leasing, management, and community in one mandate.
Frankfurt, Berlin, Stuttgart. More in preparation.
Pure residential rentals. No commercial activity for you.
WHEN NO ONE IS MANAGING THE BUILDING’S LEASING AS A WHOLE,
THE OWNER LOSES MONEY EVERY DAY.
Every empty apartment costs rent that never comes back. The chain behind it starts harmlessly, and none of its steps appears in a monthly report.
- 01No point of contact, no connection
After move-in, no one feels responsible. If tenants don’t know anyone in the building, they move on at the next opportunity.
- 02Turnover costs twice
Every move-out costs you marketing, make-ready work, and the empty weeks in between.
- 03Poor reviews
What does not work in the building shows up publicly on Google the next day.
- 04Finding the next tenant gets more expensive
A building with weak reviews can only lease through lower pricing or more advertising.
- 05More maintenance, less rent
If tenants do not feel at home, they do not treat the apartment with care. In the end, the property pays, and the cycle starts over.
THE BROKER LEASES. PROPERTY MANAGEMENT MANAGES.
NO ONE IS MANAGING YOUR LEASE-UP RATE.
THE BROKER
Commission-driven. Payment is tied to each individual lease, not to the building’s lease-up rate. No one has a financial interest in the last few percentage points; that is exactly where your return is.
PROPERTY MANAGEMENT
It manages, instead of leasing. Billing, building systems, and maintenance keep running. But it does not speak the language of the international tenant base that fills a furnished building.
Property management or leasing: the articleAND THE TENANT?
After move-in, no one keeps an eye on the tenant. The average length of stay drops, and with every move-out, the lease-up rate falls again.
OneHaven does exactly this job, only better. Within a residential model, without pushing you as the owner into commercial operations.
LEASING, TENANT SUPPORT, AND COMMUNITY
BROUGHT TOGETHER IN ONE DIGITAL SYSTEM.
Five building blocks, one mandate. You keep the building; we take over leasing, the lease-up rate, and tenant communication. The digital system behind it shows you at any time which apartments are leased, what rent is coming in, and what is not.
- Your building on onehaven.de, alongside Eastside, Roomments, and The Bloom Homes
- Visibility in a search with nearly 1,000 apartments on the platform
- Google reviews for the building, excerpted from our Google profile
THAT PERFORMS
- Inquiry and application handled digitally, with a fast personal response
- ID and proof of income are uploaded and reviewed
- Viewing on site or live by video, including from abroad
LEASE-UP RATE
- Expiring leases are handled before anyone gives notice
- Re-leasing starts before the apartment sits empty
- Lease-up rate and rent levels are managed weekly
- A local team in the city that knows every apartment personally
- Easy to reach, even after move-in. No call center
- A community in the building, so tenants stay instead of moving on
- Leasing status by apartment, with the same view for you and for us
- You see which apartments are leased, what rent is coming in, and what is not
- Inquiry, screening, contract, and tenant contact all run in one system
We define furnishings and equipment together based on your target budget. We set the standard in advance, so the final calculation fits the building, not the catalog.
FIGURES FROM THE PORTFOLIO:
WITH ATTRIBUTION FOR WHO ACHIEVED THEM.
We separate what leasing delivers from what the product delivers. Otherwise, a figure can look better on paper even though the result came from somewhere else.
This figure comes from the product, not from leasing. We keep it separate so you can see which lever has which effect.
YOU CAN SEE WHERE EVERY UNIT STANDS AT ANY TIME.
No monthly PDF, no screenshot in a presentation. You get access to the same system our team works in.
- Leased units by floor and apartment
- Reservations and new leases
- Rent levels over time
- Real numbers every week, no projections
If an apartment is vacant, you see it the same day we do. That is the point.
TWO PERSPECTIVES FROM ASSET MANAGEMENT.
“A rent increase of nearly 40% and lease-up rates close to 99% during initial leasing quickly convinced our investors of OneHaven.”
Daniel Haase Director Asset Management, Hamburg Trust Group “OneHaven helped us reach a lease-up rate of more than 90% within a few months at one of our larger properties.”
Markus König Director Asset Management, Real I.S. 
WHO ONEHAVEN IS A FIT FOR
AND WHO IT IS NOT.
We’d rather tell you upfront than after two meetings.
A GOOD FIT
- A furnished apartment building with 50 to 300 units in Frankfurt, Berlin, or Stuttgart
- You want the building rented and managed professionally, not just administered
- Temporary furnished housing starting at six months, for residential use, with one lease per apartment
PROBABLY NOT A FIT
- A single apartment or a few scattered units
- A traditional unfurnished standard property for long-term rentals
- A one-off individual service, such as initial leasing only with no ongoing operations afterward
Not sure whether your property fits this category? Tell us about it. We’ll tell you openly whether we’re the right partner.
IN FOUR STEPS TO FULL LEASE-UP.
From the first look at the property to tenant retention. With no upfront investment on your part.
- 01UNDERSTAND
THE PROPERTYYou tell us the location, size, condition, and goal. We look at the building and tell you openly what is possible and what is not.
- 02DEFINE THE
LEASING SETUPWe define the target audience, rent level, and furnishing standard. We set the furnishings and equipment together based on your target budget.
- 03LAUNCH MARKETING &
LEASINGThe building goes through the Trust Check and onto onehaven.de. Inquiries, screening, viewings, and digital leases all run in one system.
- 04SECURE LEASE-UP RATE &
TENANT RETENTIONExpiring leases, re-leasing, and tenant support continue. You see the current status every week in the live dashboard.
WHAT OWNERS ASK FIRST.
Does OneHaven also rent out individual apartments?
No. We work with entire furnished apartment buildings with 50 to 300 units. The leasing rate is managed at the building level, not through a single apartment.
What exactly does OneHaven handle?
Marketing, leasing, managing the leasing rate, tenant contact and community, plus the digital system behind it. Five areas, one mandate.
As an owner, does this make me a commercial landlord?
No. The rental model is residential, with one lease per apartment and terms generally starting at six months. No commercial intermediate leasing.
How is this different from a broker or property manager?
A broker is paid for an individual closing. A property manager manages the existing portfolio. We take responsibility for leasing performance over time, including tenants who already live in the building.
How quickly does it work?
We respond to your inquiry personally and quickly. How soon a building can go into marketing depends on its condition. During the ramp-up of Eastside Frankfurt, all 276 units were leased three months ahead of schedule.
How does a partnership start?
Send us the key details of the property by email using the “Inquiry for Your Property” button below. After that come the conversation, the leasing setup, and the mandate. Until then, there are no costs for you.

- A personal response from a real person
- No costs until there is a mandate
- If it’s not a fit, we’ll tell you in the first conversation
