talking about other property portal... Recently I just discovered that propertyguru.com.my is practicing the same methodology like iproperty (which they will burn the unused credit of the agent despite the agent perform renewal)
in such a bad economy especially for real estate, there are still companies that wanted to implement such changes, and 1 year ago I recall the sales person hard selling to us that propertyguru is different with iproperty whereby the credit will not expired so long as you renew the package, and there you go, after 1 year prior to renewal they changed their policy and burn all the unused credit.
and i see that it is totally pointless to schedule re-advertise, everyday to waste out your credit, and the only person who is making a profit or gain would be the portal developer itself.
to me, be it your advertisement on the first or last page, if the buyer really interested to purchase the said property, they will not miss out any opportunity to filter from first page to the last page to see what is being offered.
