What is key4?

What our clients say

I had a great client advisor who was very knowledgeable. Arranging the financing was straightforward and easy. I'd be happy to recommend key4.

Our key4 advisor put our minds at ease, answering all our initial concerns (is such a low-cost mortgage even possible?) with personal, expert and customer-oriented advice. Not only the sensationally low mortgage interest rates convinced us, but also the “strong bank” behind them. We've already recommended key4 to all our neighbors!

Mr. Luca Figlioli's expert, entertaining and goal-oriented advice was excellent. We were particularly impressed by how well Mr. Figlioli explained the ins-and-outs of redeeming a mortgage held with another bank. The excellent advice combined with low interest rates make key4 a very attractive partner.
