The past months we worked with Sietse on securing a mortgage and we couldn't be more satisfied with the support and guidance we received throughout the process. Our financial situation was quite complex, but from the very begining Sietse approached everything with clarity and professionalism, taking the time to explain every step, helping us understand our options and make well informed decisions. A notable example that stood out and made us feel grateful for having Sietse as our advisor is when we encountered an odd situation where the seller's realtor acted unethically, attemtping to pressure us into sharing our private tax information in an effort to favor another buyer (who turned out it was the realtor's own customer and he wanted to get commission both from the sellers and his own buyer). Sietse stepped in immediately, firmly protecting our private and confidential tax data, while clearly and professionally communicating to the realtor the strength of our financials position. His intervention not only de-escalated the situation, but also ensured that the purchase process of our new apartment moved forward on fair and transparent terms.
