Eighteen months after we went to settlement on our Great Falls property, I want you to know how pleased Elaine and I remain about the way you handled and executed the sale of our Great Falls property. Your knowledge of the local market and professional approach in a most difficult real estate environment was spot on and brought the positive results we all sought. You remain our realtor of choice; as they say, “You are the man!”
— Ron Faucher

Just a note to let you know how much I appreciate your kindness and patience with me during the year it took my to finally purchase my home. I am sure I dragged you through at least 50 houses from Vienna, to Arlington and you were always so upbeat, informative and unpressured. THANKS! I would not consider working with anyone else.
— Jim Burns
"
Thank you so much for all you and your staff did to bring the sale of our home…to a successful conclusion. We couldn’t have done it without you.
— John and Gladys Pouch
Quick Answers

Choosing the right luxury real estate agent

Common questions from buyers and sellers across Northern Virginia.

  • Look for proven local sales, high-end listing experience, strong negotiation skills, and a marketing process built specifically for luxury homes. The right agent should understand pricing, presentation, buyer behavior, and the specific community where your home is located.
  • A luxury listing should include professional photography, cinematic video, aerial imagery, staging guidance, digital promotion, listing syndication, and a clear strategy for reaching qualified buyers.
  • Luxury markets can shift street by street. Local experience helps with pricing, positioning, buyer expectations, negotiation leverage, and understanding what makes each community distinct.
