Sandro J. Stadelmann
Sandro Julian Stadelmann, B.A. in Real Estate Management, began his career in 2005 as an electrical installation technician, gaining hands-on experience in residential construction. Following military deployments in Syria and Bosnia, which instilled values such as loyalty and reliability, he became a real estate agent in 2011. Between 2017 and 2024, he built successful agencies in Vienna and Dubai. Thanks to numerous media appearances and a strong network, he is now recognized as an expert in real estate on Mallorca.
Precise punctuality, expertise, and above-average commitment are what set Mister Immo apart.
I always felt perfectly advised and was impressed by the swift and highly professional handling.
