Great service, super transparent, can only recommend
I have been using Proper API services for the past few months with my consultant, Andre, and so far I am very satisfied with the experience.
I really enjoyed my consultations: they were always clear, transparent, and without any pressure.
Originally, I wanted to better understand how to invest in real estate and how to use it for tax advantages. Andre did great explaining all the details and helping me build a clear strategy for this. He also advised me on a private pension plan and compared it with the more traditional investments I was using at that time
I am happy with the service and knowledge I've received and would recommend them to others

Great consultation experience
It has been a great experience receiving consultation from Lukas and Pierre.
Lukas has helped us with a wide range of topics, including financing, pension plans, and legal and private insurance options and inquiries. He has been very thorough and has provided us with detailed information throughout the process.
We have been working with Pierre on property investment. He has been very patient and thorough every step of the way, from explaining the basics to helping us find good apartment offers and choose the right one, and then guiding us through all the steps afterward, from securing a loan to the notary appointment.
We are very grateful for all their help and very happy with their assistance.

Positive with room for improvement
Overall, my experience working with the consultant was positive, especially in terms of responsiveness and support throughout the purchasing process. Communication was generally clear, and they were available to assist when needed.
However, there were some challenges regarding the initially projected rental income. The expectations presented at the beginning did not fully align with the actual achievable rent, which required additional clarification and negotiation later in the process. While this created some uncertainty, I appreciate that in the end a solution was found, and a subsidy from the seller was arranged to bridge the gap.
That said, reaching this outcome required considerable back-and-forth and was at times a tiresome process. A more realistic initial assessment and clearer communication around rental expectations would have made the experience smoother.
In summary, the consultant was helpful and committed, but there is room for improvement in setting accurate expectations upfront.

Hello Fatih,
Thank you for your honest feedback and for taking the time to share your experience. We really appreciate your kind words about our support and availability throughout the purchasing process.
We also understand your point regarding the initial rental expectations. We generally aim to calculate conservatively and assess what rent may realistically be achievable. However, especially for new-build properties during a first-time rental, final rental results can vary depending on market demand and the specific tenant situation at the time.
From now on, we will be even more cautious about discussing rental expectations up front.
We are glad that, in the end, we were able to find a solution together in your case. Thank you for your trust and your open feedback.
Happy with the experience
Happy with the experience. Spoke with André who has been very communicative and educated me a lot on what to expect with the process. I’m already feeling much more financially stable and capable.

A trustworthy partner for long-term financial decisions
I’ve been working with Proper API across insurance, investments, and real estate, and on the whole I’ve had a positive experience.
The insurance and investment consultations were professional, attentive, and well-suited to my needs. The real estate process was, as expected, the most demanding — stretching over about a year and a half — but the team supported me through the learning curve, and the purchase itself was well-coordinated.
One area where I feel there is room to grow is the post-notary phase. In practice, the formal signing is not the final step — there are still several important actions that need to be taken before the purchase is truly complete. As a first-time buyer, I wasn’t aware of this, and despite asking about next steps on a few occasions, I didn’t receive a clear picture in time. With a simple checklist or a brief overview of what comes after signing, I would have been able to take ownership of those steps myself and avoid some of the complications that arose. It’s a small addition that could make a meaningful difference for clients going through this process for the first time.
When support was needed most, it did come through — and I genuinely appreciate that.
One tip for future clients: always read through every document yourself, from start to finish. It pays off.

Hello Anton,
Thank you very much for your thoughtful and balanced review.
We truly appreciate your trust in Proper API across such important long-term financial decisions, from insurance and investments to real estate. It means a lot to hear that you felt well supported throughout the process and that our consultations were professional, attentive, and tailored to your needs.
We also really value your honest feedback regarding the post-notary phase. You are absolutely right: the signing itself is not the final step, and especially for first-time buyers, the period afterward can still involve a number of important actions and responsibilities.
Transparency is very important to us, which is why we always share all relevant documents throughout the process. At the same time, we know that for first-time buyers, having the documents does not always automatically create full clarity around what comes next.
This is exactly why we have now created a dedicated checklist for our clients, including a clear timeline, FAQs, and an overview of the next steps after the notary appointment, so there is much more clarity throughout the process.
Thank you as well for highlighting this point so constructively. Feedback like yours helps us improve the client experience in meaningful ways.
We’re glad we could support you on your journey and appreciate the trust you placed in us. Wishing you all the best with your property and your long-term financial plans.
Professional and Competent.
The consultant was very competent and didn’t push for anything, he was just showing the way and letting you take all decisions .
I felt very well supported all the way .

Helpful and trustworthy
They help with all kinds of questions, and I have found them to be trustworthy.
I like how well any of my queries are answered and laid out in a comprehensive manner. I have received help for matters that did not directly bring the company itself gain. They are also legally bound to act in their customers’ best interest, which brings further trust points.
Sometimes responses take a while, but I take talking to a human over any kind of AI any day, as they can cater to my specific needs and take data protection seriously.
