I think, the most cheapest one is at Tuen Mun. The rent is around HK$4,000 - $5,000 for a flat of 2 bedrooms. You may also consider the "Serviced Suite" at Hotel in Tin Shui Wai. It's around HK$6,000 per month with no security deposit required. All furniture, phone-line and some electric appliance like refrigerator are included.
Hope the information is helpful.
Happy New Year!
