Karshis & Co. | Premier North of Boston Real Estate Agents

We Don't Just Sell Homes. We Create Winning Strategies.

At Karshis & Co., we believe every client deserves a competitive advantage.

Real estate isn't simply about putting a sign in the yard or unlocking a front door—it's about strategy, timing, negotiation, marketing, relationships, and knowing how to win in every market. That's where we thrive.

Serving North of Boston, Greater Boston, Boston, and Southern New Hampshire, Karshis & Co. has built a reputation for delivering exceptional results through relentless advocacy, innovative marketing, expert negotiation, and an unwavering commitment to our clients' success. Whether you're purchasing your first home, selling a luxury estate, investing in your future, or navigating a complex transaction, our mission is simple: maximize your opportunity while minimizing your stress.

We don't believe in average representation.

Every property receives a customized marketing strategy. Every buyer receives a competitive game plan. Every seller benefits from pricing backed by market intelligence—not guesswork. Every negotiation is approached with preparation, creativity, and persistence because we know the smallest details often create the biggest financial outcomes.

Our clients trust us because we solve problems others can't. From competitive multiple-offer situations and luxury properties to probate sales, investment portfolios, new construction, off-market opportunities, and challenging negotiations, we consistently find solutions where others see obstacles.

What truly sets us apart is our relentless pursuit of excellence. We combine local expertise with sophisticated technology, targeted digital marketing, powerful storytelling, professional presentation, and data-driven decision-making to position every client for success. Behind every transaction is a team that communicates proactively, anticipates challenges before they happen, and never loses sight of what matters most—your goals.

Relationship matters

At Karshis & Co., relationships always come before transactions. Much of our business is built through repeat clients and referrals, a reflection of the trust we've earned by delivering results and providing an experience that extends well beyond the closing table.

Because buying or selling a home is more than a transaction—it's one of life's biggest financial decisions.

You deserve a team that treats it that way.

Relentless in our pursuit. Strategic in our approach. Exceptional in our results.

Welcome to Karshis & Co.

Success Stories

We worked with two other realtors before we started working with Erika. She's attentive and really knows how to get things done. We were searching for three years, looked at countless houses, and gave so many offers that weren't accepted. It took Erika only two months to meet with us, learn what we were looking for, and get it done. We looked at three houses within a month. The third one on a Sunday, we ...

Kristen helped us in the sale of our condo, which went for more than the listed price. Kristen is a true professional, and she made me and my family feel at ease during the whole process. She answered all my questions (there were hundreds) with patience and clarity. For open houses, showings, inspections, government documents, etc., she is very organized. My family and I will endorse and recommend her wh...

Success Stories

Kristen, Erika, and Team were fantastic to deal with. From the moment we interviewed them as prospective selling agents, we knew they were the ones to sell our home. As a family, we have lived there for 3 generations, and it was more than wood and nails; it was a place where I was raised and where we raised our family. Kristen and Erika provided us with a plan and schedule that we put into action. They g...

Success Stories

We came into the home-buying process with zero clue of what to expect or where to begin. Erika educated us so much on the process and what to expect. She took away all the fears. Originally, we were in no rush to find the perfect home, but after only 4 house viewings, we found it, and Erika made sure she did everything she could and then some to write an incredible offer! This team is incredible and will...

Success Stories

Kristen and her team helped us purchase our first home, and we were so grateful we had them on our side. From the beginning to end, they were always in communication with us, and were always quick to respond to any questions or concerns. To no fault of Kristen and her team, our first home became an extremely difficult new construction process due to a builder and seller team that became unprofessional an...

Erika Ternullo and the entire team at Karshis and Company are nothing short of amazing. Our experience buying our first home was met with true professionalism from start to finish.

Our family is forever grateful for being represented by such a wo...

Working with the dream team at Karshis and Co made the stressful home-buying and selling process as enjoyable and easy as it could be! I highly value communication and transparency (I like to have all the info, from all angles) and we definitely got that from Kristen and her team. We were looking for our forever, dream home so we weren't willing to compromise on what we wanted and they never made us feel...

Success Stories

There are no words to describe how amazing Erika Ternullo is as an agent. She goes above and beyond for things that are not even hers to handle. She dealt with three other siblings and me on selling my home, and also had to deal with the process of probate court in order to sell my family home. It was not an easy transaction and took almost 4 months from the sale to the closing. Erika handled everything ...

Success Stories

Kristen, Erika, and Meredith are an incredible team! At the beginning, middle, and end of our work together, they were professional, kind, attentive, and so much more. We did not have any experience in the real estate world and this team guided us all the way. We could have not gotten our first home without their amazing dedication and expertise. They were also able to recommend a great lawyer and mortga...

Erika Ternullo of Karshis Team was extremely helpful in tackling our home purchase. We were purchasing out of our original home state and really taking a leap to end up in our forever dream home. Erika worked hard to help us ensure that would happen. She was always ready to answer questions and advocate for us. She put us in touch with a super helpful lender since the home needed work, and we needed a co...

Kristen is more than knowledgeable in her field. We sold our first house and bought our forever home with Kristen.

She was very helpful working with us within our budget when buying and she is upfront with the entire process on what to do to best prepare ...

Success Stories

I will start off by saying that we were not in the market to buy or a sell our home at the time. We stumbled upon a listing in North Reading (where we currently lived) and needed to see it. I immediately contacted Kristen and she got us a showing the next day! Erika met us and jumped through hoops to get us into the house since there was an issue. As for the selling of our house, we had an open house wee...

Success Stories

Wow, truly can't say enough about Kristen and her team. From the moment that we entrusted her with selling our house, she made the process seamless and easy. Consistently communicated about next steps and easing our minds - even until late in the night and first thing in the morning. Her team is just as amazing. We were hearing updates, next steps and just friendly reminders each day on what will be happ...

Success Stories

Erika and her team were great to work with when selling our condo in MA, as we live out of state. Erika was always willing to meet with contractors or take care of anything needing to be done locally. She was also a great resource when we had questions or needed recommendations. It made the process very smooth. We highly recommend her!

Success Stories

We recently bought our new home in Middleton, and we absolutely could not have done it without Kristen Karshis and Erika Ternullo from Karshis and Co. Buying during a time of high inflation, incredibly low inventory, and with my own high anxiety and very specific vision was no easy task - but Kristen and Erika were there for us every single step of the way. From the start, they understood how important t...

Success Stories

My fiancé and I have just bought our third property with Erika Ternullo and her team. She helped us find and most importantly lock down our own beautiful single-family home after buying our investment properties. When you work with Erika you’re not just her client but you become her friend. The Karshis team is so incredible and easy to work with making the whole process smooth and leaving out guesswork. ...
