I live in TST and have been flat hunting most of last week around Kowloon. I currently flat share with my good friend, who has been living in this flat for 3.5 years, both this flat and the previous one he stayed in (Jordan) was done through this rather quirky estate agent (licensed but does it as a side job, commission is negotiable). She said that rents have plateaued, they could be due for a slight drop.
She showed me around what was suitable for me, and was pleasantly surprised with what I could get for my money (not high expectations, don't mind older flats).
