Over €5,500 commission for setting up a Buy-Out Bond from a scheme that is winding up? Sounds excessive to me.
For that level of commission, I presume he went through a fairly detailed fact-find and risk analysis with you to determine the most suitable Buy-Out Bond product and fund for your needs? Were other options explored, e.g. other Buy-Out Bond providers? Did you get a detailed recommendation in writing explaining why the particular Buy-Out Bond and fund is most suitable for your needs, over and above others that were considered?
If the answers to any of the above questions are NO then shop around - any Financial Broker can set up a Buy-Out Bond for you.
