I've worked with a few different realtors in the past, and I can honestly say that all those experiences pale in comparison with what Mark has provided for my wife and I. He's been patient through literally years of us picking through listings, amazingly flexible about scheduling showings, and once we finally found a house we loved he guided us through negotiating with the seller and got us an amazing deal on the place.
Anyone who's been through the process before knows that this is not where it ends - Mark went out of his way to facilitate communication between mortgage broker, escrow, seller, etc... going above and beyond his duties as a buyers agent. We were floored by his deep knowledge of every aspect of the process and his ability to keep cool and collected through everything, even through a couple of bumps in the road.
Throughout it all, Mark not only does his job, not only goes beyond his job, but he truly enjoys doing it...this I think might be the best thing of all, and it really shines through. Hands down he is the best realtor I've ever worked with, Los Angeles or otherwise!
