I had the pleasure of working with Guillaume and Marlon, and I cannot recommend them highly enough. Their professionalism, responsiveness, and in-depth knowledge of the Luxembourg real estate market were evident from day one. Whether it was navigating the legal aspects, providing market insights, or simply answering every question with patience and clarity, they consistently went above and beyond. Their advice was always thoughtful and well-informed. Highly recommend.

I had the pleasure of having Guillaume at fidem represent me for my mortgage application. He is extremely client centric, very knowledgeable about the whole process and presents a clear picture based on your financial situation and the options available, almost acting as an advisor in your best interest in relation to your real estate purchase. In a transaction which can seem daunting, he simplified the whole process and explained to me very clearly the possibilities while always keeping my best interest as a client in his mind. He went over an above in terms of service that I could expect as a client, I am genuinely very impressed by his dedication and I am sure the larger team at fidem operates with the same client centric focus.

I fully recommend Guillaume and fidem.lu for your mortgage needs and wish the team best of luck!

A Pro-Active, Client-Focused Mortgage Assistance Start-Up

I recently had the pleasure of working with the team at FIDEM to secure a mortgage, and I was thoroughly impressed by the level of service and support they provided. As a young start-up in the mortgage industry, FIDEM has clearly made client satisfaction a top priority.

From the very beginning, the FIDEM team was incredibly pro-active in reaching out to banks on my behalf and keeping me informed every step of the way. They took the time to ensure I understood all the details and complexities of the mortgage process, making what is typically a daunting task feel straightforward and manageable.

The FIDEM team's dedication to their clients was evident in their attentiveness and responsiveness. They were always available to answer my questions and provide guidance, and they worked tirelessly to streamline the process and secure the best possible terms for my mortgage.

In an industry that can often feel opaque and overwhelming, FIDEM provided a refreshingly client-focused experience. I highly recommend their services to anyone in the market for a mortgage. The team's professionalism, expertise, and commitment to their clients is truly exceptional.

Do you already have one or more current real estate loans?

Loan rescheduling
