While I have never bought a house from Darrin, I do know that he is a VERY dynamic person. He's really involved in the process. I like Darrin because his assertive attitude and friendly conversation is engaging and can actually make you feel comfortable very quickly. I wouldn't buy something from someone who couldn't engage on a real level. He might seem intimidating to the introverted, but he's not intimidating at all.
And he seems to sell a lot of houses.
