All brokers in Zwinderen

We really had a very nice and enjoyable viewing. Even though the purchase ultimately didn't go through, that certainly wasn't due to the real estate agent. Very pleasant to deal with, took plenty of time for us and helped with much more than just showing us the house itself. An incredibly fine experience!

Karl seemed very involved and was even approachable outside of office hours. Also created a very detailed structural report. In short, an expert and engaged realtor.

A broker who is technically very knowledgeable. With a lot of experience, he helped us with research into our potentially new home to buy on Terschelling. We received many tips from him and the brainstorming regarding various possibilities made it a particularly pleasant experience! We definitely recommend Passies Bouwadvies en Makelaardij! Kind regards, Michel

Karl took all the time for our building inspection. With a lot of knowledge and precision, he examined the property to be purchased, taking us along with his wealth of building expertise and experience as a real estate agent. Thanks to him, we now know exactly what we would be buying, but also which points of attention there would be. Karl does his name justice, because he is a man with passion for his profession! Through his years of experience in construction and real estate brokerage, he has helped us more than perfectly with all his knowledge!

Karl has helped us tremendously with the handover of our home! He is very skilled and professional, with a good eye for detail. We are very happy with Karl's work and the many tips we received from him. Thanks to him, our house will be handed over in perfect condition. The communication was also very pleasant and smooth. Highly recommended!

Incredibly well assisted with the inspection of our home. Karl spontaneously helped us during our handover after an inspector booked through another company failed to show up. Thanks again so much!

My experience: - Poor communication/unreachable - Did not keep appointments - Drove away potential buyer

Karl was 1 of a number of brokers I had asked for the sale of our house in Sleen, the feeling was immediately good; I knew him from when he still worked for construction company Bekman. He was actually the only one who estimated the asking price well, in our opinion. Within a few months, he had sold our house and everything was arranged smoothly, even though it was a property with commercial space where you have to find a buyer. No problem for Carl, who also knows exactly from a technical construction point of view how things stand. Carl, I wish you much happiness and health and that you may sell many more houses. Greetings Sandra and Jan van Oenen

Lying and cheating are highly valued. This man has also never heard of communication. Truly a fat 1! Amateur! Also threatening after a bad review.. And if you apparently write a bad review, my lord makes a lot of effort to undo it at Google. Says enough.

It's unbelievable that this realtor doesn't score higher on Google, which he truly deserves. We have come to know Karl as an honest, reliable, skilled and very amiable man with a heart in the right place. It is clear that he is not only professional but also has a warm and empathetic personality who is committed to his clients. His ability to excite potential buyers and his detailed knowledge of the house clearly impressed us and the buyers of our house and certainly contributed to the success of the sale.

We met Karl as our real estate agent. A very pleasant person to deal with. Calm, polite and has knowledge of construction matters. Took plenty of time for the viewing and additional questions. A nice experience!

Karl Passies as a real estate agent is like a good friend who sells your house for you with all the expertise that goes with it. He understands the emotional rollercoaster you go through as a seller, and he's very professional both as a building expert and a real estate agent. Our house, a monument, was sold well and quickly, and we found another beautiful nostalgic farmhouse. Home sweet home. Thanks Karl!

Very satisfied!

My house was sold through Karl and I only had positive experiences. He always called back the same day, even from his vacation spot. Involved, friendly, helpful and professional. Very well-organized presentation. And he even replaced a broken lock before the new buyers took ownership of the house.

Karl performed the structural inspection of the property in Joppe that we want to purchase for us in June 2023. This was to our great satisfaction! Calmly, personally and expertly, Karl told us what points needed attention, but also what was good. An honest story without exaggerating. In clear words, without becoming too technical, he answered our questions. The structural report was neatly available at the agreed time. The report also clearly included a cost indication for the work to be carried out. In short, we are very satisfied and we can certainly recommend Karl.

We are very pleased with the critical perspective during delivery by Mr. Karl Passies. Everything is being carefully reviewed. He has an eye for the good things and certainly also looks with a critical eye. Mr. Passies looks at details. He even went onto the roof and inspected the roof edging and solar panels there. Also, the window frames, which we cannot see from the inside, were examined. Extensive inspection that benefits the client. He knows the ‘rules’ within construction and comes up with a solution as to how it should be done differently. He has a calm demeanor and points out defects to the contractor in a tactful way, to which the contractor has no response. Our contractor did not appreciate this. Mr. Passies was described by the contractor as being too critical. And that is what’s most important for the buyer. We are happy that we hired Mr. Passies. Thank you very much Karl.
