Signing an intermediation mandate with a real estate broker does not entail any immediate costs. You will only be financially committed if the broker succeeds in obtaining a loan offer that you accept and sign. The brokerage fee is then included in the financial package for your loan. However, if you have engaged a broker and his or her work has led to a lowering of your bank’s loan conditions, the broker’s fees are legitimate. This second task is governed by the« advisory mandate« . Indeed, it’s thanks to his efforts and expertise that you’ve been able to benefit from these improvements.
