About to go door knocking....

[Luka Milicevic]

I'm in a very hot market and everyone is doing direct mail. I want to stand out and I'm actually going to knock on a few doors.

My problem is....

I have no idea what to say when they open the door. 

I've been thinking and I don't just want to show up and get straight to asking them if they want to sell me their property. 

Any guidelines would be greatly appreciated!
