Looking to sell your apartment building?
We look forward to meeting you in person
We are particularly interested in properties with development potential – for example assets with a complex or unclear legal situation, a sub-optimal letting status, or dated building fabric with deferred maintenance. We start where others stop and use our judgement to create lasting value.
If you are looking to sell your apartment building, Rosenbaum Group could be your partner. We are not estate agents; we buy exclusively for our own portfolio. As an owner-managed company we work quickly, discreetly and, above all, fairly. For us that means transaction certainty above all: we carry out one thorough review, then give a binding commitment – and complete the purchase without renegotiation.
Why owners sell to us
We acquire real estate in Berlin and the eastern German federal states and have a continuous appetite for new purchases. Our focus is on residential assets.

From viewing to notary appointment
We buy for our own portfolio and take our own decisions – without lengthy committee procedures and without a bank proviso. That is why it usually takes around six weeks from the first property offer to notarisation – already including the two weeks of statutory review period, which begin when the draft purchase agreement is sent out. After that it takes around another four weeks until the purchase price is paid. Every step has a binding date – that is our understanding of transaction certainty.

Payment of the purchase price
As soon as all conditions for payment are met, we pay out the agreed purchase price – punctually and reliably.
From first contact to payment of the purchase price – plannable, binding and discreet. Agreed terms are not renegotiated.
All timings are guideline values drawn from our acquisition practice. The actual duration may depend, among other things, on the processing time of the land registry office.
Guaranteed discretion
Your price indication
Do you still have a loan to repay and need to pay an early repayment charge to your bank? As a borrower with strong credit standing, we are often able to take over your bank loan – which means you save the early repayment charge.
For your non-binding price indication we initially need only:
- A tenancy schedule showing net cold rents, lettable areas and number of rooms
- An up-to-date extract from the land register
- Floor plans (not essential)
You can then simply send us these documents by email – for your first enquiry a short message via the form is enough. Once we name a purchase price, it stands: we buy without a financing proviso and without a committee proviso – that is your transaction certainty.
