Mario van Janss Makelaardij is een zeer goede aan en verkoopmakelaar. Na alle bezichtigingen was er altijd contact over het verloop van de dag. Ons huis was dan ook snel verkocht.

Mario Janssen is een verademing in makelaarsland. Veel kennis van zaken, staat voor je klaar en 'voelt' jouw stijl van voors- en tegens goed aan. Een hele persoonlijke 'kleine' aanpak. Dat paste perfect bij onze wensen. Bedankt Mario!

Nice collaboration with Mario! He came well prepared for the first meeting and dares to set ambitious goals. Clear communication, he switches quickly and thinks along.

We needed a valuation report for the financing of our renovation. Within a week after first contacting the valuer, we already had the report. Not long after that, the financing was already in place! Fast service, clear agreements and all appointments were neatly followed up.

I urgently needed an appraisal. My mortgage advisor recommended JANSS Makelaarsij. They acted very quickly and the content of the report also contributed to a quick acceptance of the mortgage. In short: A recommendation!

Peter Bool

Good communication and very pleasant help with the sale of my house. Mario reacts quickly and keeps his appointments. Recommended!

Recently had an inspection with Mario. The inspections are a lot more personal and we really got the time to look around. Also, all questions were answered immediately. We didn't buy the house, but we will use Mario anyway if we have a house in mind to guide us through the purchase.

For years and years he has supported me, family and acquaintances with purchases, sales and appraisals. A traditional craftsman who really stands by his customers, great to see that they still exist! Looking forward to our next purchase :-D

I asked Mr. for some general information about the rates. I was spoken to politely and professionally. I felt absolutely no annoying (commercial) pressure. Nice to experience that again in 2025!

Christiaan de Vries

I needed an appraisal report for a renovation. There was some urgency here. A day later the recording and 3 days later I already had the report. We are satisfied!
