Credit intermediary / mortgage broker (pośrednik kredytowy)

A firm or person that professionally helps you obtain a loan: compares offers from the banks it works with, prepares the application and guides you through the process. A mortgage credit intermediary must be entered in the KNF register.

An intermediary is usually paid by the bank, and sometimes also by the client — they must tell you this before you start working together. They must also tell you which lenders they work with.
