You can't buy trust—that's why property owners have relied on our team for years

13 June 2026 · Autor: Andreas Gräfenstein


Why owners have trusted our team for years

Why do we do what we do? Because there are people behind every property.

Whether it’s a single-family home, a condo, a villa, a plot of land, or an investment property—for many years, we’ve been supporting owners with the sale, rental, and valuation of their properties. For us, it’s about far more than square footage, purchase prices, or contracts. It’s about trust.

Trust isn’t built on big promises

For many owners, selling a property is one of the most important financial and personal decisions they’ll ever make. That’s why you need a partner who listens, gives honest advice, and realistically assesses the market.

Our mission is to guide owners safely through this process—with experience, transparency, and a marketing strategy tailored to the property and the owner’s personal situation.

We live in the region we advise

Real estate is always a piece of home. That’s why supporting owners and prospective buyers in Treptow-Köpenick and beyond is more than just a job for us.

Our team has deep regional roots: Olga Braun lives in Müggelheim, Ariane and Andreas Gräfenstein in Hessenwinkel, Bernd Spredemann in Köpenick, and Less Ehrcke brings not only his experience in property management but also a perspective from the surrounding area.

As a result, we know many neighborhoods not just from market reports or viewings, but from our own daily lives. It is precisely this knowledge that helps us realistically assess properties and specifically target suitable buyers or tenants.

Behind every team member lies a unique story

Behind every successful real estate transaction stands a team that is passionate about its work.

Olga Braun supports owners and prospective buyers with great heart and personal dedication. What’s especially nice: We first met Olga as a client when Ariane brokered her property at the time, laying the foundation for her current home.

Bernd Spredemann brings a wealth of experience that cannot simply be learned—but is gained only through many years of successful work with people and real estate. We originally met him during a property viewing. Today, he supports property owners and prospective buyers with his calm, confident demeanor.

Less Ehrcke complements our team with valuable experience in property management and a special focus on condominiums and residential complexes.

Ariane Gräfenstein is the heart of our team. For over 20 years, she has supported owners and buyers with experience, empathy, and passion.

Andreas Gräfenstein handles marketing, digitalization, and strategic matters behind the scenes—ensuring that properties today are not only well-presented but also marketed in a contemporary way.

Every property deserves its own strategy

No house, no apartment, and no plot of land is exactly like another. That’s why we don’t offer off-the-shelf marketing.

A single-family home for a family, a condominium as an investment, a plot of land with development potential, or a villa in a prime location each appeal to different target groups.

We carefully assess which buyers or tenants are a good fit for the property, what kind of presentation makes sense, and which marketing channels promise the greatest success.

We appreciate awards—but recommendations mean even more to us

Of course, we are delighted to receive awards and recognition. They validate our work and demonstrate that quality speaks for itself.

However, personal recommendations from former clients are even more important to us. Because trust isn’t built through advertising, but through good work, reliability, and honest advice.

Many owners come to us on a recommendation or hire us again when their life circumstances change. That is precisely the greatest validation for us.

What unites us

A love for our region. A passion for real estate. And the conviction that successful real estate brokerage always begins with trust.

Because in the end, it’s not just about houses, condos, land, or purchase contracts.

It’s about home.

If you’d like to know the current market value of your property or which sales strategy suits your personal situation, we’d be happy to advise you with no obligation.
