It's always interesting to see how long the REA leaves the sign up after the property has sold- more free advertising for them and their agency.
Funny one was where I took down the sign after buying a property. A week after I removed the sign they came and knocked on the door to ask for it back. I gave them an earful that they should have removed it immediately and told them it went to the tip. A very disappointed RE departed the property.
Cheers
