Aiza came to Horizon Properties in 2007 and has since obtained her Real Estate Sales License and is working towards her CPM certification. Aiza is invaluable to Horizon Properties – she wears many hats here at Horizon and can take a sale transaction through from writing a contract to closing. Her role as Property Owner Relations Manager entails keeping the line of communication open with owners so they stay informed as to the status and / or issues with their properties, as well as insuring that the accounting involved with processing the payment to owners for rental proceeds is accurate and timely.
Away from the job, Aiza likes serving the community with her family (visiting homeless shelters and the elderly). She loves reading and has an immense thirst for knowledge.
