Ioannes Margarites was the recipient of a confiscated land from Arsenios Tzamplakon located between Serres and Zichna and of a zeugelateion, which belonged to Kantakuzenos, near Zichna. He became these estates with the revenue of 55 hyperpyra and was fully exempted from paying taxes (κῦρ Ἰωάννην τὸν Μαργαρίτην ἀπὸ τῆς περὶ τὰ Ζίχνα καὶ τὰς Σέῤῥας ἀφαιρεθείσης ἀρτίως οἰκονομίας παρὰ τοῦ Τζαμπλάκωνος κυροῦ Ἀρσενίου, ἔτι δὲ καὶ ἀπὸ τοῦ περὶ τὰ Ζίχνα διακειμένου ζευγηλατείου τοῦ Καντακουζηνοῦ, ποσότητα ὑπερπύρων πεντήκοντα πέντε, καὶ κατέχῃ καὶ νέμηται ταύτην ἐλευθέραν πάντη καὶ ἀκαταδούλωτον). The charter, which was also an inventory of his property, was issued in January 1342 by Michal Papylas Romanos.
