Ring the agent and ask? Write the number on a piece of soft paper and then wipe your bum with it - that's about it's value. Wait a few months for it to appear on free sites like onthehouse.
Simon, it was passed in at auction. Back on the market for $520K but vendors looking for between $500-520K (probably an unrealistic expectation). So it hasn't sold.
It is for lease at $450pw so they have some funds coming in rather than letting it sit vacant.
