Mark is a fantastic agent. We bought a foreclosure with him last year, and though the process wasn’t painless — the selling bank lost the title for a few weeks and kept us from closing on time, which was a huge hassle since it was a cross-country move — Mark was *completely and totally awesome* at negotiating compensation for the hassles and in driving down the final price after the appraisal came in at lower than our offer. We ended up paying even less than we thought we would when we entered escrow; and we already thought we were getting a great deal.
Aside from the great work he did on the financials, Mark was also patient and helpful with the complex shenanigans we were going through. He was very responsive to us and to the sellers and was always available. I’ve recommended him to friends and will definitely use him when we sell/buy again.
