Purchasing through a real estate agent…

I read the book “Rich Dad, Poor Dad” by Robert Kiyosaki and he said that when he is buying a property, he tells his realtor to pick 10 properties and offer 50% of the purchase price just to see what kind of responses he gets. Even if most of them laugh at him, maybe 1 out of 10 will come back with an offer of just 75% of the purchase price.

Do you guys do anything like that?
