Le foncier rural et le bâti de prestige exigent une bonne connaissance du marché et des points de comparaison. À travers ces articles, mon ambition est de lever le voile sur la complexité de ce marché et des réglementations, afin d’offrir aux propriétaires des analyses fiables pour pérenniser et valoriser leur patrimoine.

Parcours & légitimité

Après avoir validé son cursus à l’Université catholique de Louvain (UCLouvain) en 1996, Yves Lange affine son esprit d’analyse au sein du groupe GlaxoSmithKline, tout en poursuivant des études complémentaires à HEC Liège en logistique. C’est en 1998 qu’il prend les rênes du Comptoir Foncier, une maison historique réputée pour son approche sur mesure des domaines d’exception, des massifs forestiers et des terres agricoles.

Aujourd’hui, son quotidien se partage entre l’évaluation de portefeuilles immobiliers complexes et la vente de propriétés bâties de caractère, de terrains agricoles et forestiers. Son adhésion à l’Institut Professionnel des Agents Immobiliers (IPI) et sa certification par la Chambre des Experts Immobiliers de Belgique (Cibex) témoignent d’un engagement déontologique strict et d’une méthodologie d’expertise reconnue par les tribunaux et les institutions financières.

Engagements & approche

Pour Yves Lange, l’immobilier d’envergure repose sur deux piliers : la discrétion et la connaissance des points de comparaison pertinents. Une estimation ne doit pas chercher à séduire, mais à refléter la stricte réalité du marché pour garantir la sérénité des transmissions familiales ou des arbitrages financiers.

  • 2 accréditations officielles : IPI et Cibex
  • 100+ ans d’histoire et d’archives techniques au sein du bureau
