I was a first time buyer. I bought a condo unit for Cash. Derek Colen was very available at all times, friendly, and helpful. The Redfin closing process was done by Rocket Close with help from Derek. The condo was in the North Bethesda Maryland area. Derek advised me as to the choice of a unit, and was always helpful as to my questions.
