For the building savings sum, I think differently... a small classic 20-30k building saver, that would be a good thing. But 100k?! You pay 1000€ (maybe even more) connection fees, get a ridiculous interest rate on savings, and also pay account management fees.... Who does that and why? Well, to each their own.... maybe you should also look for a reputable agent. I have never had good experiences with such things in bank consultations anywhere. Ask around among acquaintances who they can recommend there are unfortunately bad apples everywhere
