Bart Bastiaansen

As a manager with a technical background, he earned his stripes in the corporate world. Driven by his passion for Amsterdam and its housing, he made the switch to real estate in 2005. He began his real estate career as the office manager of an agency based in IJburg, and then spent 15 years at Voogd. At the end of July 2024, he joined SEM. Bart works throughout the city and is, above all, a seasoned specialist in IJburg and Zeeburg, knowing every corner of this group of islands inside and out. He is also active in the Houthavens area, where he has built up substantial expertise.
His love for the water and boating allows him to effectively convey the added value of living by the water. This is how he earned his nickname: “the Sailing Realtor.” What stands out is his consistent ability to achieve high returns on sales, all while maintaining a strong focus on the human aspect. This results in smooth processes with satisfied buyers and sellers.
