Wallace, I agree with you when you say that – depending on the style and quality of finish and renovation / furnishings cost involved, the rents vary widely. –
But maybe you must check better the market because you can have a dreaming place and location but at this price, who really can to be interested?
For example, I live in the center in Jinjiang district, sure in an old apartment but big 250 squares meters at 7th floor with a big terrace. Price of rent is on 5000rmb.
Now, if I want restyle completely every room, I’m pretty sure that I will not use more than 20k – 25k rmb.
After, thinking about a subrent, I can ask 10k rmb for every month but maybe still to be difficult to sell!
Anyway try to put your apartment on AirBnb.com
