Selling Your Home Shouldn’t Be Complicated

Why Hire Us

Selling a home isn’t just about square footage and sales prices, it’s about letting go of a chapter you’ve written over the years: the hallway where your kids took their first steps, the kitchen where holidays came to life, the backyard where time seemed to slow down. When life calls you into a new season—whether it’s to move up, to downsize, to make a fresh start, or to bid an emotional goodbye—it’s okay to feel overwhelmed. It takes the right team to meet these moments with insight, care, and bold thinking. You need a guide who sees the full picture, honors your story, and walks with you every step of the way.

Without clarity, selling a home can feel like navigating a storm without a compass. The wrong advice or timing can leave you vulnerable, chasing price drops, losing leverage, or missing the buyer who truly connects with your home. Thankfully, it doesn’t have to be that way. We are Diane & Brian Hagarty, a Realtor® duo that prides ourselves on bringing much more than market knowledge to our clients. We bring strategy, energy, and empathy—because relationships are at the heart of everything we do. Backed by 36 years of experience, we anticipate what others overlook, position your home with intention, and negotiate with your future in mind.

When you work with us, you’re partnering with a team that cares deeply about the same streets, schools, and stories you do. Whether you’re preparing to sell a cherished family home, a luxury property, or a countryside farm, we tailor our approach to meet your goals with clarity and compassion. We take the time to listen, provide expert guidance, and create a personalized strategy that reflects your unique story, all backed by market insight, data, and a trusted network of professionals.

So let’s talk. Not a sales pitch—just a real conversation about where you are and where you want to go. From there, we’ll map out a plan for success and take it one thoughtful move at a time.

Diane and Brian Hagarty

What Our Clients Are Saying...

"Diane and Brian have helped me sell two homes in Northern Virginia. Their professionalism is unparalleled. When we first met with Brian, I was expecting the typical and unqualified “sign here and trust me” pitch that most realtors spew. Not so with the Hagartys. They showed up with in-depth analyses on regional trends, highly nuanced and detailed profiles on our specific property and its positioning in the market, and a level of attention to detail that is all too uncommon in their industry. Our genuinely positive experiences with the Hagartys is the highlight of our having bought and sold seven houses over the years. If we were still in Northern Virginia, we’d be doing it again (and again). Diane and Brian practice at the top of their profession. You can do no better."

- Billy S.

"I would highly recommend Brian and Diane to anyone who is either selling a home or looking to purchase a home. I recently retained Brian and Diane to sell a farm for me. I was very happy with their expertise in all aspects of the real estate market. Their advice on the property’s list price and evaluation of offers was excellent. Furthermore, their advice on what needed to be done to get the house ready for sale and the contractor recommendations that they made were invaluable in accomplishing the quick sale of the property. Brian and Diane were a pleasure to work with and always responded promptly with answers to any questions that I had. I will unhesitatingly turn to them for help in any future real estate transactions."

- Jim W.

"Diane and Brian are awesome realtors and people to work with. They are responsive and very knowledgeable about the market. They helped us get top dollar for our home and helped with the negotiation of our new home. They have a lot of connections and will help you get the home of your dreams. Be patient, and the right home will come along."
