Honest advice instead of wishful figures
An asking price that is set too high prolongs the marketing period and often ends up costing money. A price that is too low costs you straight away. That is why we derive the asking price from verifiable data and explain every step to you.

What clients often ask us
What does the estate agent cost me when I sell?
Commission is only payable if a purchase contract is concluded. We agree the amount and split in writing in advance. For flats and single-family houses, the statutory split applies: if both parties pay, they pay equal shares (section 656c BGB).
How does the statutory commission split work?
When a flat or single-family house is sold to consumers, there are two models: either both parties engage the agent and pay the same amount, or only one party engages the agent and may pass on at most half to the other party – and only once it has paid itself (sections 656c and 656d BGB).
Who pays when a property is let?
The party who engaged the agent (Bestellerprinzip). If the landlord engages the agent, the landlord pays. The commission may not exceed two months’ net rent excluding service charges, plus VAT.
What does the market price assessment cost?
Nothing. The assessment is free of charge and non-binding.
How do you determine the price?
We view the property, evaluate the documents and compare them with current market data such as standard land values and property market reports. From this we derive a price range and explain our reasoning to you.
Why not simply start with a high price?
A price that is too high often leads to few enquiries and a long marketing period. Long marketing periods act as a warning signal to prospective buyers and can push down the eventual price.

Corpus Makler is a service of Corpus Callosum Dienstleistungsgesellschaft mbH (DLG for short), a member of the Dortmund-based Corpus Group with offices on Schützenstraße. Under the DLG umbrella, several property-related divisions work hand in hand. For you, that means short lines of communication if you need more than one service, and a contact person who knows the other divisions.
Commission: clearly regulated, in writing in advance
A commission is only payable if a purchase or tenancy agreement is concluded. We agree the amount and split in text form in advance. When flats and detached houses are sold to consumers, the statutory split under § 656c BGB applies; for lettings, the "whoever orders pays" principle applies.
