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 UBS key4 mortgages.

Marco Gujan


Our UBS key4 mortgages 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 UBS key4 mortgages to all our neighbors!

René und Franziska Kasper


The expert, friendly and goal-oriented advice from my client advisor was excellent. Special mention should be made of how well my advisor understood the details of redeeming a mortgage held with another bank. The excellent advice combined with low interest rates make UBS key4 mortgages a very attractive partner.

Bernhard Tobler


The superb advice from my client advisor and the offers from various banks made the decision to go with a UBS key4 mortgage over our house bank an obvious one.
