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


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 UBS key4 mortgages a very attractive partner.

Bernhard Tobler


Thanks to Mr. Figlioli's excellent advice and the offers of various banks, the decision to go with UBS key4 mortgages rather than our house bank was obvious.
