More about Karen Sousa

Karen Sousa, Realtor, Accredited Staging Professional

After years of owning an interior design business and being an avid “weekend warrior” of home renovations with my husband, I entered into the real estate arena in 2004. I’ve seen the extreme highs and lows of the market since then. I have learned so much over that time and I value my experience. Each transaction is different because each buyer and seller has different reasons and motivations for selling or buying a home. It’s so important to have a seasoned professional by your side guiding you along the way.  I am happy to share my knowledge and guidance with my clients. I have consistently held a top spot as a multi-million dollar producer. I attribute that success to aligning myself and clients with some of the best business partners in Mortgage, Title, Inspection, Contractors, Electricians, Plumbers, Landscapers, Photographers, etc…It’s my pleasure to work alongside these professionals to ensure your transaction goes as smoothly as possible.

 I was born and raised in Southern NH. When I got married, my husband and I lived in a few different towns and houses in NH until we settled and raised our family in the quaint community of Hollis NH. It didn’t matter if the houses we lived in were new or old, there always was a project to be done. We were knocking down walls before it was a “thing” on HGTV. We got into a pattern of buying, fixing and selling. Each house sold quickly and for the top value at that time. I have taken that knowledge and shared it with my clients. You don’t have to knock down walls or spend a ton of money but you do have to stage your home if you want t to sell it quickly and for top market value.

My business philosophy is grounded in my Christian faith. I believe in and practice “The Golden Rule”.  My business has been blessed and has grown through the relationships and friendships that have developed. My clients have referred me to their family and friends many times over the years. My goal is to “go above and beyond” for my clients. To know that I have helped someone achieve a goal or a dream has been a gift and I am very grateful for the opportunity. I hope to have the opportunity to help you achieve the same.

Karen certainly went above and beyond my expectations. She was always very level headed and gave knowledgeable advice. She didn’t just want to put us in a house but rather a home. Sean, Raymond NH 

We really appreciate Karen’s professionalism in a very difficult market to successfully sell our home and get us to our target town, neighborhood and dream home! We are thrilled! Christine and Mike,  Nashua NH 

Karen Sousa went above and beyond what I ever expected from a real estate broker. She worked extremely hard on getting me the price I wanted for my home and did analysis to back up our price. She also worked very hard on making sure I paid and appropriate price for my next home. She was on top of all the details for buying and selling. I have sold homes 3 other times, and by far she was the best broker I have ever dealt with. Beth,  Hollis NH 

Karen has been fantastic. We were extraordinarily happy with her. We took all of her recommendations for preparing the house for the market including using her contacts in construction/contracting and we got an offer after having the house on the market for only one week, and we got asking price. She was fantastic. All of the people who viewed our home commented that it showed very well and we feel like we owe a large part of that to Karen. Rien and Dianna, Nashua NH 

As my buyer’s agent, Karen went over and above in helping me and looked out for my best interests. She recommended a real estate lawyer and did necessary research. Her concerns and questions were very useful in assisting me. She was equally as helpful, knowledgeable, and efficient as my sales agent. I appreciate all that she did to make me transactions go smoothly. Heidi, Hudson NH
