Seller of 43241 Bent Twig Terrace, Ashburn
Kathy has been a joy to work with. She has helped my wife's family with several home sales/purchase, and this was my first opportunity to have her represent my family of four. She's simply been the best, and has put family first throughout the entire process. We're fortunate to have her on our side and I'm 100% certain she'll treat your family the same way she treated ours. Thank you Kathy!
Seller of 101/20602 Cornstalk Terrace, Ashburn
Kathy and her team took care of everything. They staged the condo to give it a warm home feeling versus the geo-bachelor work week housing look. They took care of getting the inspections and paperwork needed to get through closing. Within a few weeks I had multiple offers at my selling price, which was at top end of the spectrum for the area, and closing process was simple and easy. There was great communications from our first meeting to end of process, so I always knew the status and no surprises on actions to take. Kathy was always available to me, if I questions or concerns.
Buyer of 202/20577 Snowshoe Square, Ashburn
Kathy helped me find and purchase my first home and I couldn't have done it without her. She saw many properties with me, over multiple weeks, and was always happy to see more no matter how far away they were. She always had great insight to share on the places and helped with insight to narrow down places to determine what I wanted as we saw more locations. Once a place was chosen Kathy was amazing in reaching out to all of the individuals involved and ensuring the process moved forward smoothly and with no issues on multiple occasions. She is a great agent and I will absolutely be recommending her to people I know and return to her in the future for any future purchases!

Buyer of 20760 Exchange Street, Ashburn
Highly Recommend . We had a wonderful experience with Jennifer Mack. Vanessa Simon was our realtor and went above and beyond to help us find the right home for us. We looked for over 2 months and she never hesitated to be available when a property was available for viewing. She sent us listings that fit our needs and even helped walk us through the process when we were looking at the potential for a new build. Even after we purchased our new home she has consistently continued to give us advice ( recommended deck company, flooring company etc.). We truly value everything Jennifer Mack Properties and Vanessa did for us.
