Founded in Virginia in 1968, Long & Foster has grown to be one of the nation’s largest residential real estate companies and a full-service organization with mortgage, settlement services, insurance, and property management services.


In 2017 the company was acquired by HomeServices of America, a Berkshire Hathaway firm, making it one of the nation’s largest real estate brokerage firms. Operating today under the Long & Foster | Christie's International Real Estate name, the company operates with the same spirit it’s traditionally brought as a family-owned and managed company. Long & Foster continues to delight customers as a one-stop real estate and financial services firm with great local knowhow. Our connections with the Long & Foster family of companies can help us coordinate all the moving parts to ensure you are ready for the big day.

A Full Service Team

As your real estate agents, we will not only provide you with all the information you need to make an informed buying or selling decision, but also can connect you with mortgage, title, insurance providers, and more. Full service means we make it easier for you every step of the way, from contract to closing and beyond.

Finding the right mortgage can be just as important as finding the right home, helping make you a more competitive buyer. Our trusted partners at Prosperity Home Mortgage, LLC, can educate our clients about their mortgage options and help get them pre-qualified early on to strengthen their buying position. A member of the Long & Foster family of companies, this local lender offers personalized service, competitive rates, and a quick, flexible, and paperless lending process. 

Long & Foster’s family of settlement companies will help you become the official owner of your new home. These companies handle the legal issues, paperwork, and funds in your real estate transaction. From conducting comprehensive title searches to providing title insurance and preparing the necessary settlement documents, this team can help coordinate a smooth and efficient closing on your home.

Insuring your home is a critical part of home ownership. Our partners at Long & Foster Insurance will take the time to understand your needs and provide recommendations on coverage that works best for you. As an independent and full-service agency, they comparison shop for you, finding the highest quality protection for your home at the best value. Their comprehensive coverage includes homeowner’s, condo, flood, umbrella policies, and more. They will translate policy information from insurance lingo into simple, easy-to-understand terms so you can confidently select the right coverage.

“When the house we were about to buy was found to have some major mold problems, Marnie helped us get out of the deal and found us a new place—one that almost perfectly matched our needs and expectations—in less than 5 days.”
