I will suggest to go for unfurnished property, it will cost you around QR 4000-4800 depends on locality, Asian school with transportation for two kids 1000 X2= QR 2000, QR 2000 for living expense and QR 500 for transport, Total cost of living would be QR 8500 - 9300, You can save QR +10500, But it totally depends on your living standard.
