Stephen I was a landowner near Almásfüzitő in 1269. Alongside Matthew II and Peter I, he began to acquire possessions in the north-western counties of the Kingdom of Hungary and left the ancient estates of the genus in Fejér County (e. g. Csákvár). During the rule of Béla IV, he already crossed the Danube, because the king donated Palást, Hont County (today: Plášťovce, Slovakia) to him. Stephen exchanged his land in Hetény, Komárom County (today: Chotín, Slovakia) to Kistapolcsány, Bars County (today: Topoľčianky, Slovakia) and 100 marks. Before 1274, he also owned Mahola, Vajkóc (today: Volkovce, Slovakia) and Tajna (today part of Tajná, Slovakia), however, these possessions and 50 marks were sold by Stephen for the lands of castle warriors in Bori (today: Bory, Slovakia).
