The way David Marks sees it, in the world of real estate -- knowledge is power. Pairing responsive, transparent communication with unrivaled market insight, David helps every client find the right solution for their distinct lifestyle. David has long been been drawn to real estate. With 9 years of commercial industry experience managing properties and a penchant for home improvement projects, it was only a matter of time before David found his place on the residential side of the business. He officially made the move in 2012 and hasn't looked back. Today, David is a dedicated agent on the Seattle scene who's built a reputation as the Realtor clients can always count on. Known for his informative, full-service style and vast expertise, David goes above and beyond to be there for his clients every step of the way -- whether they're relocating to a new area or seeking more space to accommodate their growing family. David recognizes that just like the homes he sells, no two clients are alike. That's why he takes the time to get to know the people at the heart of each transaction, so he never designs the same experience twice. Well-versed on the ins and outs of construction, David offers the perspective his clients need to reconcile any repair's cost with its potential return down the line. This is critically important when preparing a home for sale. He's also a proven estate deal expert, overseeing the vast array of services associated with this nuanced type of transaction -- from hiring vendors, assessing and managing improvements, to executing the sale. A Seattle resident of 40+ years, David has a local knowledge base that knows no bounds. His own personal experience exploring the area over that time is only bolstered by the many years he spent selling to grocery stores and shops across the Seattle/Bellevue region as owner of his own wine distribution business. The bottom line? No matter where your home search or sale takes you, you'll always find your way with David. When he's not working for his clients, you can find David playing tennis or golf, traveling abroad, sampling good food and wine, and spending time with his wife and 10 year old daughter.

David and Sarah from Portico Real Estate helped us find a new house, and sell our old house, in a very short period of time when the market was not helpful. David and Sarah were fantastic and helpful every step of the way. I hope we don't have to move any time soon, but I would beg Portico to help us again if we did and recommend them to anyone else looking for the next step in their home ownership journey.

Camilla was super flexible and helpful the entire process! I was making a cross-country move and her attentiveness and responsiveness made purchasing an easy experience. We toured many houses together and she kept in mind all of my likes and dislikes as she curated lists of houses to visit. She went above and beyond in accommodating my time and travel to maximize the efficient use of my short trips to WA.

Brenda helped me a lot get knowledgeable about buying a house. She explained every detail every house we visited in the tour.She arranged the tour perfectly in order very smoothly efficiently. I was not able to buy a house this time but I will definitely ask her to help me buy a house when we are ready. I was so lucky to have her as real estate agent. Thank you Brenda. I really appreciate it.

As a first time homebuyers we had so many questions and felt overwhelmed at times, Brandon made the entire process easy to understand and made it such a positive experience. We felt supported from start to finish. Couldnt have asked for a better experience. He is indeed very patient and supportive every step of the way! Highly recommended!

I purchased a condo found on Seattle Washington while living in the state of Illinois. David was oustanding as my representative in every respect. First he listend carefully to my criteria and only brought me listings that fit exactly. Second, he provided expert market advice on negotiationg price. Third, he pomptly followed up on my every request for information or special services. Fourth, he found a mortgage lenderthe knew precisley how to issue loans for this specific condo for which there were legal issues that were a problem for other lenders. Finally, he took care of the whole transaction in my absence, with me only signing electronic documents. A top notch guy to be sure.
