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.
Wenn Sie Ihr Mietshaus verkaufen wollen, dann könnte die Rosenbaum Group Ihr Partner sein. Wir sind keine Makler, sondern kaufen auf eigene Rechnung. Als inhabergeführtes Unternehmen arbeiten wir schnell, diskret und vor allem fair. Dazu gehört für uns vor allem Transaktionssicherheit: Wir prüfen einmal gründlich, sagen dann verbindlich zu – und ziehen den Ankauf ohne Nachverhandlung durch.
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.
We offer transaction certainty
We pay quickly
We offer you the best price
From viewing to notary appointment
Wir kaufen auf eigene Rechnung und entscheiden selbst – ohne lange Gremienwege und ohne Bankenvorbehalt. Deshalb vergehen vom ersten Objektangebot bis zur Beurkundung in der Regel rund sechs Wochen – darin enthalten sind bereits die zwei Wochen gesetzlicher Prüffrist, die ab Versand des Kaufvertragsentwurfs laufen. Danach dauert es noch einmal rund vier Wochen bis zur Kaufpreiszahlung. Jeder Schritt ist verbindlich terminiert – das ist unser Verständnis von Transaktionssicherheit.

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.
