We are very satisfied with the guidance we received from Johnno during the purchase of our first home. Very good accessibility and nice contact throughout the entire process from A to Z. We definitely recommend Hier-makelaars to others.
Both Dennis and Johno are real professionals with one big exception compared to most real estate offices: they understand that a lot is at stake for you, they are very accessible regardless of the day or time, they keep their appointments and always think with you. In the meantime my second property has been sold with the help of Hier Makelaars and in both cases I am very satisfied.
Very nicely helped. Especially the communication I appreciated enormously, you were always kept informed and therefore you never had to stand in front of surprises. Thank you Johnno, Dennis and the rest of the team!
Dennis and Johnno from Hier Makelaars do everything well. Always directly reachable and switch very quickly. Advantage of a small team! Together determined the sales strategy for the sale of my mother's apartment, and this was completed within three weeks at a great selling price. They know what they are doing and have a lot of experience with it. They are just really good at what they do. Congratulations!!! Many thanks! Arjan Kroon
Here Real Estate Agents helped us find the perfect home. And for that, even in this time, we only had to make 1 offer on a property! Thanks for the various good advice.
We can only say that we recommend these real estate agents to everyone! We were helped by Johnno. Johnno is always in a good mood and friendly, was ready for us when we needed him, always kept his appointments and acted super professionally. Because of this, we experienced the entire sales process as very pleasant and carefree. Thank you for the guidance, Johnno! Kisses, family Erbay
We are very satisfied with Hier Makelaars. Dennis and Johnno arranged and took care of everything very well for us. Selling your house worry-free is extremely valuable. Thank you for the good handling and care in the sale of our house!
In the past, I have already had good experiences with buying and selling a home through Hier real estate agents. And this time again very satisfied with the sale of my house. A smooth, clear sales strategy with a successful result.
HEARTFELT THANKS Here Makelaars! For your guidance in the sales process from A to Z, your positive and driven attitude, communicating with short lines, quick switching and keeping appointments. Very pleasant! Many actions are linked to selling a house. Thanks to your proactive approach and step-by-step execution of actions, it remains manageable and the process even becomes enjoyable again! Dear Dennis & Johnno, thank you very much for the pleasant cooperation. You two accomplished a lot of work and are a pleasant team. Also heartfelt thanks to Nouf for the mediation, Yasmine for telephone advice and compliments to stylist Agnita & photographer Wanda. Professionals who all make an important contribution to the total. Also incredibly kind that Dennis organized the open day. The sale proceeded quickly thanks to good planning. And satisfied with a nice offer. Heartfelt & Global greetings, Patricia
Pleasant and easy communication and a great sales strategy. Which resulted in us selling our house within two weeks
Een slechte ervaring!
We had a great experience with Hier Makelaars. Johnno helped us find our new home and thanks to his expertise, we found our new house within just two weeks. He guided us through the entire process, informed us about all the details, and was always available to answer all of our questions. We wholeheartedly recommend Hier Makelaars to everyone looking for a new home!
Dennis & Johnno, thank you very much for the pleasant collaboration. You have helped us a lot. The contact was very agreeable and especially the quick responses so that we could quickly switch.
HIER real estate agents are very good brokers. They know very well what they do and which strategy to choose for both purchase and sale. In addition, the accessibility and information provision are very pleasant, extremely fast and professional. We definitely recommend HIER real estate agents!
Onze excuses voor de vertraging bij het delen van onze feedback. We hebben een geweldige ervaring gehad met Dennis en Johnno tijdens ons traject naar een eigen huis. Dennis is een rustige en professionele makelaar die altijd beschikbaar was voor bezichtigingen en de tijd nam om alle belangrijke details uit te leggen voordat we een beslissing namen. Zijn duidelijke begeleiding en ondersteuning maakten het hele proces veel soepeler. Daarnaast willen we Johnno bedanken voor zijn hulp tijdens het hele aankoopproces; ik waardeer zijn steun enorm. We bevelen Dennis en Johnno van harte aan aan iedereen die op zoek is naar betrouwbare en deskundige makelaars in Nederland.
Good communication and guidance. It was particularly nice that I was always kept informed of changes, questions, and deadlines.
Thank you, Johnno and Dennis, for all the support and very good guidance in selling our house. We constantly felt that we could completely rely on your advice and expertise, and that feeling proved to be correct.
At Hier Realtors, the lines are short. Both Johnno and Dennis keep you, as the selling party, well informed. With their expertise of the current market and friendliness, they managed to sell our house for a beautiful amount. Even when things went less smoothly afterwards (with the buyers), they were on top of it and we were kept up-to-date every minute about the status of affairs. They really guide you from A to Z. In short, we definitely recommend Hier Realtors! …
Johnno from Hier Real Estate has helped us fantastically with the sale of our house. We quickly adjusted together, the house appeared quickly on Funda and was sold within two weeks. The entire process from the introductory meeting to completion was excellently arranged. Johnno and team, massively thanks 👍🏻 …
We zijn Johnno en zijn team bij Hier Makelaars ontzettend dankbaar! Ze waren altijd bekwaam, betrouwbaar en ongelooflijk behulpzaam tijdens ons hele traject naar een eigen huis. Hun expertise en toewijding maakten van wat een overweldigend proces had kunnen zijn, een soepele en prettige ervaring. Dankzij hun begeleiding hebben we ons perfecte huis gevonden en we bevelen Hier Makelaars van harte aan iedereen die op zoek is naar een betrouwbaar en professioneel makelaarsteam! Een echte aanrader!
What started as an informal conversation ended up being a whirlwind. Two weeks after we had an informal conversation about selling our house, we found our new home on funda. Luckily, it was also for sale through HIER real estate agents. Because the purchase and sale were handled by Dennis and Johnno, everything went incredibly fast. Within two months, everything was settled. If we ever want to move again, they are the first people I will call!
What a journey we have made together! If all goes well, we've been at it for about 3 years but nothing is too much for Dennis or Johnno. After a year of searching and constantly being outbid, we had given up, more than a year later we contacted them again and Dennis and Johnno immediately had time to start the search again, with incredibly good advice and most importantly not to make a hasty decision I can certainly say that they are there to help and that this should also be the driving force! Both buying and selling have been of great value to us that we could always call for information, and secretly we still do that now! Top people and once again incredibly thanks for all the conversations and advice!
Top service! We came to Johnno's office for an introductory meeting and actually 4/5 weeks later we received a yes on our offer! We are super happy with the good service provided by Hier makelaars. Hier makelaars is highly recommended as a buyer's agent!
We engaged Here Makelaars (Nieuw-Vennep) to sell our house in Hoofddorp. Our main contact person was Johnno. He managed the sale with a lot of knowledge and an excellent strategy that worked brilliantly. Furthermore, he maintained very good contact with us throughout the entire process. We can only recommend the real estate agent and Johnno.
A very pleasant collaboration! Johnno is friendly, helpful and often goes the extra mile. We have been enormously happy with his help.
From the first day until the key handover, we were helped incredibly well. Johnno is truly a top performer, nothing is too much to ask! Thanks again for all the help and support! Greetings Jermaine&Shenaaz
Een fantastische ervaring met de aankoop van een huis via Juhnoo en het team van Hier Makelaar. Zeer professioneel en het hele proces verliep vlekkeloos. Ze gaven gedetailleerde begeleiding bij elke stap, inclusief het opstellen van het bod. Ik kan hun diensten van harte aanbevelen. Als ik mijn huis ooit weer wil verkopen, kom ik zeker weer bij hen terug.
We had a great collaboration! Johno and Dennis are very knowledgeable and helped us well with buying and selling! They are customer-friendly, transparent and honest, which we appreciate. They think carefully about offers, matters surrounding purchase and sale, and clearly explain how everything works. We definitely recommend Hier Makerlaars as a sales and/or purchasing broker!
Received very professional guidance from Dennis, Jonno and Yasmin regarding the sale of my home. Good service, always reachable, even during vacation, and pleasant communication. In short, true professionals!
I can only say that Over Hier Makelaars is highly recommended. What a great team for the purchase and sale of our homes. Dennis Cos, Johnno Swan and Yasmine helped us tremendously, advised and informed us throughout the entire process. They think along with you and are very warm and professional. We are very grateful to them that we are looking forward to a beautiful future thanks to them.
Very pleased with the help of Hier Makelaars. Our purchasing agent Johnno Swan helped us very well in finding the right property. They are easily accessible if you have questions and always have the patience to help you properly. They listen carefully to your wishes and ensure that they show you the properties that match. All in all a very good experience. We definitely recommend them!
During our purchasing process, we came across Hier Makelaars (and especially Johnno) as the selling real estate agent for properties we were interested in, and this experience was so positive that we subsequently asked them to be our own sales representative. Hier Makelaars is knowledgeable, professional, easily accessible, and guides you well through the process as a (seller's) agent. I would recommend Johnno and colleagues to everyone.
Here Realtors has helped us very well with the purchase and sale of our home. Clear agreements and pleasant personal contact. We were well informed and advised during all steps of the purchase and sale. During the purchase of our new home, we had already given up hope, but Here Realtors managed to make our dream house possible for us.
It was a good experienced. We are very satisfied with the collaboration and we could always call, use the app, and it went really well, so highly recommended.
Excellent real estate agent. Good and fast communication. Clear sales strategy. Sales text required a few adjustments, but those were quickly processed. In short very satisfied and definitely recommend this agent.
The entire process regarding the sale of my house went smoothly and, at my request, very quickly. Everyone from Team Hier Makelaars always contacted me neatly (where necessary) and were always very transparent about the status and the evt. required steps. Able to switch quickly and highly involved. All in all, I entrusted them with the sale of my house with complete conviction. With a super result. Nothing but praise and can certainly recommend every Hier Makelaars…
Very good contact, clear about all aspects, helpful and always friendly. They think along with you regarding possibilities and give tips and ideas!
Dennis and Johnno from Hier Makelaars guarantee excellent service. They communicate clearly and regularly get in touch. They respond quickly to questions and are always ready to help you. They are expert brokers who sold our house quickly and with a beautiful result!
We experienced the sales process as very efficient and pleasant. Appointments are well kept, and we were always well informed after viewings. All in all, very satisfied and no comments.
Very pleasant collaboration with both Dennis and Johnno for the sale of my house. The service is fast and good, there is a lot of involvement and they took my wishes into account without creating unrealistic expectations.
Highly skilled real estate agency. Easy to reach, clear and fast communication and no 9 to 5 mentality.
From the beginning correct and expert. Clear explanation of sales strategy. Good guidance and excellent contact with all involved employees. That the sales strategy worked became apparent in the end with the realized selling price. Highly recommended if you want to sell your house!!
We sold our house with the help of HIER real estate agents. What a service. Good communication. Thanks Johnno.
My house sold by Hier Makelaars. Very pleasant experience. Always kept well informed about the process by Johnno. Highly recommended!
Our apartment sold through Hier real estate agents. Good advice, clear communication and property sold well and quickly. So definitely recommended.
Sincere thanks to Johnno and the team for handling everything related to the purchase of our house and making sure that everything went smoothly! A recommendation!
Here, a realtor sold us a house and then also sold our house. Both top experiences!
Very nice but above all very informative conversation with a well-understood explanation. Highly recommended brokers here. J.H de Wit
Very professional. Everything went smoothly and on time. They gave us an excellent review and explained the process very well. Thanks for your help in finding our new home.
Had good collaboration with Dennis, Johnno and Yasmine. Level-headed and realistic. Always available and willing to answer questions, and also fast. In short, good service! Therefore, I recommend choosing this (local) real estate agent.
After missing a few times, we decided to choose a purchasing broker. With the help and advice of Hier Makelaars, we now have our dream home in Almere Poort! I am very pleased with the guidance throughout the entire process and can recommend Hier makelaars to everyone! Top people! Thank you!
In 2023 I bought my new house and sold my old house with the help of Hier Makelaars, and what a top experience that was! The people at Hier are really super friendly and professional. They took all the time to help me and explained everything very clearly. They made everything so easy, and were also always available for questions or if I didn't understand something. What I liked best was how clear and transparent they are, and they truly keep all their promises. I never had to worry about whether something would or wouldn't happen, they were always on time and did exactly what they said. That really gave a lot of peace of mind! They weren't just a real estate agent, but truly a partner who gave me advice on everything. From the price to negotiations and the best timing to buy or sell, they had an answer for everything. Super handy! So if you want to buy or sell a house, I recommend Hier Makelaars 100%. They take care of you and are really super good at their job. Big thumbs up for the whole team!
Here is a fine and knowledgeable real estate agent with good insight into the market and developments within it. Contact with the office was very personal, because the team isn't so large everyone knows what's going on, who you are and why you're calling them. As a sales broker, definitely recommended!
Very nice collaboration(s)! Good guidance, clear agreements that are also kept. Just a very pleasant cooperation! Thank you for the good care!
We have already looked at a few real estate agents in the city and chose this one because they showed us prices and information based on facts, and did not just claim anything without proof. The whole process went smoothly and …
Very satisfied with the collaboration. The communication was clear and there was good brainstorming. I also found the online portal pleasant to work with.
🙏 …
Het verkoopproces verliep vlekkeloos. Dennis en zijn team waren professioneel en hielden me altijd goed op de hoogte. De verkoop vond plaats binnen de verwachte prijsklasse en het hele proces, van fotografie en styling tot inspectie, plaatsing op de markt en bezichtigingen, werd zeer professioneel afgehandeld.
Even after the sale of my house (see previous review, 10 points), there were also issues when I still rented the house for a bridging period. They were present again during that handover. That gives a very nice and familiar feeling. Give them the grade 10
