how do i ask a vacant unit for it's rental price at duxton road in singapore?

Answer 1

Err, it will be difficult to solicit an answer from a vacant unit. You will need to find its owner and ask. Or you can get a housing agent to do this for you, if you do not want to do it yourself. Housing agent can access home owner database as part of their work.

Answer 2

Slip a note in the mail box or under the door...
