I agree with Andy about building rapport.
I am pretty new at this as well but the successful investors around me do exactly what Andy mentioned.
One gentlemen, we'll call him Gus is about 75 yrs old and he's a professional birddog. I guess you could say he's a free range wholesaler. He doesn't get tied up with contracts, advertising, etc... Every deal he finds, and it seems as if he has about 2 a day, he gets by talking to people. That's it! He is considered one of the best closers around by some of the most powerful, wealthy, real estate investors in town. He's simple, respectful, will talk your ear off, and seems to care about people. His words are, "To treat people every bit as well as they aspire for themselves to be. If they respect you and trust you then you'll make money." Picture some one like Robert Duvall ending every conversation with phrases such as, "I preciate yur curtesy. Thank ya fur your time. It was a pleasure visitn' wit ya."
He's tells me about properties that he could get for $65k but when I call the seller they tell me $75k. It's all about the relationship!
Another investor I know who has mentored me goes into a home, gives the children some attention, looks for things to compliment the seller about. Things that have emotional connections to the family. He always gets them telling a story about something they care about so that he can LISTEN.
Another investor I know makes it a point to talk to every seller for at least 30 mins before getting into the numbers.
Conversing with people is an aspect of selling that I am working on and it's how the money is made.
Peter is also right about getting the seller to name the price. First one who speaks loses.
