Customer Reviews

What our customers say

I am very satisfied with the free rental deposit account from Heykaution. The entire process was fast, transparent and absolutely straightforward. From the application to the confirmation, everything went smoothly and was easy to understand. The clear and user-friendly app is particularly positive. All important information is clearly displayed, so you always have an overview. As a landlord, you feel well looked after and legally secure. A modern, reliable service – highly recommended!"

Private landlord with 5 units

I only have a small rental apartment, but the deposit topic was always annoying. Paperwork, documentation, interest. Now everything runs digitally, free of charge, and without discussions with the tenant. Exactly what I wanted."

Karen L.

Previously, I had to create each deposit savings book individually and file the documents. With the digital deposit account from heykaution, I now have everything centrally visible and save myself easily several hours of administrative work per year."
