Your share
Your referral is worth money. We put it in writing.
Every property manager works differently. Some give us one case a year, others an entire portfolio. That is why we have no standard rate: how high your share is depends on the number, frequency and effort of your referrals.
We set this out together in a cooperation agreement before the first case starts. We will certainly come to an agreement. And your owners sell or let quickly, because we approach registered buyers and tenants first.
A share in every completion that comes about through your referral.
Amount based on number, frequency and effort, agreed individually.
Recorded in a cooperation agreement in text form.
The sale does not become more expensive for the owner.
An owner in your management wants to sell a flat, a house or a commercial property. We value it, market it, hold the viewings and vet the buyers up to the notary appointment. On completion your company receives the agreed share.
02
Letting
We market the vacant space, hold the viewings, vet the interested parties and prepare the tenancy agreement. Your company also shares in the result for lettings. Your owners have a shorter vacancy period and you have less work. How we let
03
Several units
Do you want to sell several units in a building or a portfolio? We agree a sales plan with you and the owner: pricing strategy, joint marketing and a timetable.
How it works
From enquiry to completion in four steps.
01
Send enquiry
A few clicks at the top of this page: your request, the properties and your contact details. It takes a minute.
02
Agree the cooperation
We get in touch within 24 hours on working days. We discuss your portfolio and record the cooperation and your share in a cooperation agreement.
03
Pass on the contact
You tell the owner that you recommend us and, with their consent, give us the contact. From then on we work with them directly.
04
Completion and share
Once the contract is concluded and our commission has been received, we transfer the agreed share to your company.
Clear ground rules
When the share arises, and when it does not.
The share arises when
the contract has been concluded through BBI, for a sale this means notarised,
our commission has been received,
the owner knew about the share before your referral,
we did not already know about the wish. We pay your company, not individual employees.
No share arises when
the owner does not wish to be contacted or does not instruct us,
the property is sold or let without BBI.
Passing on documents, holding viewings, discussing the price and negotiating with interested parties is done by BBI. This way your company does not carry out any brokerage activity of its own.

Frequently asked questions
Cooperation with BBI: frequently asked questions from property managers.
Answers as of: 17 October 2026
How does the cooperation with BBI work?
Send us your request and contact details through the funnel on this page. We get in touch within 24 hours on working days to discuss a cooperation. If an owner in your management wants to sell or let, you give us the contact with their consent. We take care of the valuation, marketing, viewings, vetting of interested parties and completion.
Does a property manager earn from the cooperation?
Yes. Your company shares in every completion that comes about through your referral. We record the share in a cooperation agreement. Its amount depends on the number, frequency and effort of your referrals, so we agree it individually with each property manager. We will certainly come to an agreement. The sale does not become more expensive for the owner.
Is there also a share for lettings?
Yes. If a tenancy agreement for a flat or commercial space comes about through your referral, your company also shares in the result. The details are set out in the cooperation agreement. Your owners have less vacancy and you have less work: marketing, viewings, vetting of interested parties and preparing the contract are our job.
Does the owner have to know about the share?
Yes. We ask you to tell the owner before your referral that your company shares in the result if it succeeds, and that the owner's commission does not increase as a result. We also mention this in our first conversation with the owner. This keeps your referral transparent and avoids a conflict of interest.
What does the property manager do, and what does BBI do?
You point the owner to us and, with their consent, give us their contact. That is all. Passing on documents, holding viewings, discussing the price or negotiating with interested parties is not part of your role. BBI does this, so that your company does not carry out any brokerage activity of its own.
Which properties does BBI handle?
Flats, detached and two-family houses, multi-family buildings, residential and commercial buildings, commercial space and plots in Berlin and the surrounding area. Single properties as well as several units of a building or a portfolio. For projects we work out a sales plan with you and the owner covering pricing strategy, joint marketing and a timetable.
What costs and obligations arise for the property manager?
None. The enquiry is non-binding, you pay nothing and take on no obligation to refer. Whether you give an owner our contact details or pass their contact to us directly is up to you in each case. We record the cooperation and your share in a cooperation agreement in text form.
