The real stories — where each of us comes from and why we do this.

Ronald Kooitje 27 yrs broker & appraiser · Register Makelaar-Taxateur

Originally from Friesland, Ronald has worked in housing and financial services since 1993. After starting his career as a mortgage and insurance adviser, he became an independent real estate agent and appraiser in 1999 and founded Kooitje Makelaarsdiensten in 2006. He specialises in residential sales, purchases and valuations, combining professional expertise with a personal, practical and down-to-earth approach. Ronald is a member of Vastgoed Nederland, an NRVT-registered residential appraiser and an MMCEPI professional. He also brings an established network among Dutch buyers, sellers and people considering a move to Bonaire. Committed, straightforward and genuinely interested in people, Ronald is a down-to-earth Frisian and family man. Away from work, he enjoys snowboarding, windsurfing and music.

DT Diepstra Entrepreneur · on Bonaire since 2017

DT has been an entrepreneur all his life — from call centres and debt collection to 3D AutoCAD, before moving into the digital world through marketing and, later, software development. Entirely self-taught, he went on to teach software development in Portugal, then moved to Hoofddorp to join YoungCapital as a software developer. In 2017 he moved to Bonaire, founded Dushi Blue B.V. and converted an old art gallery by hand into four short-stay studio apartments, now let through Airbnb. A side passion for barbecue turned into Holy Smoke Bonaire, his smoked-ribs take-out. In 2021, still drawn to marketing and development, he started Bonaire Brokers — convinced the island's real estate market was stuck in 1995 — and found Bonne and Ronald to join him in changing that.

Bonne Zijlstra 34 yrs real estate · Netherlands & Bonaire

In my work I have found that not every owner needs the same thing when selling a home. One wants to hand over the whole process, while another prefers to stay in charge but still be able to draw on professional knowledge and support. With Bonaire Brokers we give owners the option to sell their home themselves, without automatically having to sign up for a full, traditional brokerage process. As the owner, you present your home on the platform and decide for yourself which parts you want to outsource. Only want to get your home noticed? You can. Need professional photography, advice in the background, help with viewings or support during the negotiations? Then you can add those services. You decide what you do yourself and where you want professional help. The fee follows the services you choose and the work you outsource.
