If your availability period is 1 or 2 months later, perhaps you may wish to start marketing at $3.5k, otherwise $3.3k range is pretty much achievable. The rapid development of CBP has made your project pretty much sought after by the expats, nevertheless, do take note that the salary scheme for expats nowadays is no longer as rosy as before.
If you need any assistance, feel free to contact me. As I am staying in the east (Tampines), I believe I can run the viewing for you more effectively.
