"Mark did an excellent job selling our house. Not only is he knowledgeable but extremely kind. He even wanted to help us with any improvements we needed to make to the house. Something that he didn’t have to offer. Genuinely a pleasure to work with."

"I used Mark to represent us for buying a Condo in Bellingham that we had found through Zillow. I contacted the local Windermere office to request a viewing of the condo, and they put me in touch with Mark. We were living out of town, and he was able … Read Moreto accommodate our schedules to travel for viewings. It was apparent he knows Bellingham very well, as we toured the area near the Condo; noting good restaurants/shops, the area history, etc., We worked up an offer and since we were living elsewhere, he was able to handle many details remotely. We had frequent interactions via phone, text and email. Mark readily had contacts for the home inspection, handeled the resulting negotiations with the seller, and arranged the small details while we were living in another city. Overall, the process was efficient and stress free. I highly recommend Mark if considering buying a home in Bellingham." Read Less
