Vrede's next destination has been the subject of fervent speculation during the summer but he has yet to commit his future to any club.
He has already discussed moves to Metalurg Donetsk, Shakhtar Donetsk and AEK Athens while RKC Waalwijk are also keen.
Iraklis appear to have now matched Roda's valuation of Vrede after initially falling short with their first offer.
Though Vrede is close to his Greek transfer, there are still a couple of minor details that could scupper the deal.
Primarily, the length of contract is a sticking point as it is unclear whether Vrede will sign a one or three-year deal.
