About David

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.
