Property investors - a booming part of the City of Melbourne's demographic - could help deliver Sally Capp the lord mayoralty, if voter enrolment figures are any indication.

The ballot to elect Melbourne's new lord mayor closes at 6pm on Friday. (If you are enrolled to vote but are yet to cast your ballot, you must submit it in person or mail it before the deadline.)

The postal votes will be counted from Monday until noon next Friday, May 18. The result is expected to be announced by May 22.
