Sezer Yilmaz

Sezer, the visionary behind Mister Mortgage, grew up in a Turkish-Dutch family that settled in the Netherlands more than fifty years ago. Watching his parents navigate the Dutch financial system inspired his mission: give today’s expats the clear, trusted mortgage guidance his family never had.

As an expat-focused mortgage broker and personal-finance strategist, Sezer serves high-net-worth clients in Amsterdam, across the Netherlands, and around the world. His background—spanning personal banking, digital communications, and even professional theatre—shapes a rare blend of financial expertise, creative problem-solving, and cross-cultural insight. The result: client-centred advice that turns complex Dutch mortgage rules into smooth, confident homeownership journeys for internationals.
