Purchase, sale and brokerage of off-market investment properties

Off Market Real Estate

OTC Real Estate Market Leader

the No. 1

In 2007 our founder Muharrem Erdogdu founded a real estate office in Wiesbaden in the Rhine-Main area. Success was not long in coming. This allowed our founder to gradually open up new divisions. In addition to the traditional brokerage of real estate for private individuals, a new field came to the fore: transactions of commercial real estate and apartment buildings for investors. 2011 marks a turning point in the company’s successful history. Since then, E1 has focused exclusively on the settlement of capital investments. One of the largest German freight forwarders was one of our first major customers. And today? We are specialists in the off-market sector. As real estate investors, we buy and sell real estate nationwide and internationally.
