ICARE IMMOBILIER
Every property deserves its own strategy
ICARE IMMOBILIER,
real estate agency in the Haut-Rhin
History of our real estate agency
ICARE IMMOBILIER is an independent real estate agency located in Alsace, in the heart of the Haut-Rhin, founded by Ulysse ROMBAUX, a graduate of ESCP Business School and former financial markets professional in Paris.
After several years in stock and currency trading, he returned to Alsace in 2022 to devote himself to real estate, his lifelong passion. With his own investment projects – ranging from acquisition to complete renovation to rental – he created ICARE IMMOBILIER to offer a structured, strategic and profoundly human service, up to the expectations of demanding sellers and buyers.
A unique approach, from the investment and the field
Ulysse has carried out numerous projects on his own account, which gives him a complete vision of the issues: financial, technical, fiscal and operational. This dual experience — investor and agent — gave rise to the ICARE method:
Controlled real estate, rigorous analysis, optimized execution.
Each mandate is handled with commitment, precision and method: realistic estimate, valuation strategy, targeted marketing and, if necessary, management of the work via our integrated AMO (project management assistance) brokerage service.

Investor Vision, High Level Agent Execution
(works, division, profitability, taxation)
for maximum involvement and responsiveness
Institutions, agents, qualified purchasers
At ICARE IMMOBILIER, we don't make volumes, we make results, with method, vision and high standards. Each property is unique. Each mission is a total commitment.
