About Me

Hi, I'm Erin Terkelsen

Anchored on the Upper Cape, where I live with my family—both human and corgi—my work as a Realtor® is defined by tenacity, strategy, and a well-placed sense of humor. I don’t just help clients buy or sell homes; I help them build their future. Whether it’s a dream home, a smart investment, or a downsizing plan years in the making, I approach every transaction with relentless determination—part detective, part treasure hunter, always persistent. I focus on the Upper and Outer Cape but have helped clients buy and sell across the region. Unlike those who chase volume, I prioritize quality over quantity—fewer clients, more attention, and better results. When you work with me, you get an agent who listens, strategizes, and works tirelessly to get you where you want to be.

With a background that includes 25 years in the high-pressure world of professional kitchens, culminating as an Executive Chef at a Boston law firm, I know how to thrive in environments where every second counts. That same sense of urgency and adaptability now drives my work in real estate. I’m direct, efficient, and unafraid to tell it like it is—whether it’s advising on the art of pricing a home or spotting hidden potential others overlook. My experience serving on Mashpee’s Conservation and Sewer Commissions, as well as the Sandwich Conservation Commission, provides valuable insights into local regulations, permitting, land use, and the nuances of town government. I bring unmatched dedication and resourcefulness to every client I work with, ensuring that no opportunity is left unexplored.

As someone who is from out of state, finding a realtor was a daunting task. Erin was the first realtor to reach out to me and made me excited to find my dream home. The challenge with this house hunt was that I was not able to be around to tour houses or coordinate meetings. She handled it gracefully and was able to meet with my son during his schedule to make sure we found exactly what I was looking for! She made the process of finding a home so easy, she was the calming factor that everyone needs and made sure that we wouldn’t settle for just any home. Her transparency was unmatched and I am so thankful for her help on this journey!

Erin is hands down the best realtor on Cape Cod! On a Friday morning, my husband and I decided we wanted to see a house that was coming on the market the next day. We found a few realtors online and made a list of people to call. Erin was the first person that I spoke to, and after talking with her, I didn’t feel like I needed to call anyone else. She met us that afternoon to get all the paperwork done and right away made us feel like we were in great hands. There ended up being multiple offers on the house, and Erin walked us through all of our options and helped us figure out what we could do to make our offer as competitive as possible, while still making sure it was the right decision for us. And we got the house! Throughout the whole process, Erin was incredibly responsive! But what really made her stand out is how well she knows the Cape. That local knowledge makes a huge difference, especially because we are from out of state. Any question we had (and we had them!), she either knew the answer off the top of her head or knew exactly who to call to get an answer. We couldn’t be happier with our experience with Erin and would highly recommend her to anyone looking to buy or sell on the Cape. We feel so lucky that we found her!

Outstanding experience from start to finish. Working with Erin was the best experience I have ever had selling a home. It sold quickly and for top dollar (over asking). Erin was prepared and extremely knowledgeable about current market conditions,and created huge interest in the listing from day one. I would highly recommend Erin and her team whether you are buying or selling.

Erin Terkelsen was a wonderful real estate agent to help us find our dream beach home! What stood out most was her patience, attention to detail, and willingness to go above and beyond throughout the entire process. Erin made what could have been a stressful experience feel smooth and manageable, always keeping us informed and making sure our questions were answered. We really appreciated her honesty and guidance. We always felt that our best interests was her priority, and we never felt pressured into making a decision. We would highly recommend Erin to anyone looking to buy or sell a home. If you’re looking for a real estate agent who is trustworthy, hardworking, and genuinely cares about her clients, She is an excellent choice!

Erin is an agent that understands the buyer’s tastes and is refreshingly honest with her opinion. She went above and beyond while suffering debilitating broken wrists(that’s plural)! My wife and highly recommend Erin for your Real estate agent. George & Donna Sousa

Erin is the best! As first time homebuyers who really didn’t know what we were doing, Erin helped guide us in the right direction from start to finish. She made the whole process much easier than we were anticipating. You can usually pick up on someone’s intentions pretty quickly, and right from the beginning, we could tell her intentions were genuine and that she saw us as people and not just a potential sale. As our agent and the sellers agent, we felt that she did a great job at mediating and making both parties happy in the end. Would definitely recommend to anyone looking to buy or sell.

Erin met and exceeded all our expectations. When comparing realtors competing for the listing, she was ALWAYS one step ahead. First with recommended painters, and other workers to spiff up the place. First to respond to our questions. Flexible as our competing schedules need to be accommodated. Texts and phone calls responded to promptly. Her advice on staging and market timing were on point. 15 days and we accepted a very good offer! She was a pleasure to work with.

Erin has been an incredible agent for us. Not only did Erin sell our house above asking price by emphasizing and recognizing what was unique about it, but also, this was after other agents told us to price it much lower using bad comps. Throughout the process she was gracious, consistent, and communicative. She managed to organize the entire deal in just a few weeks as well. During the process, Erin went to bat for us several times, even long after the home sale was completed, to ensure that every step of the process was carried out correctly and fairly. I can't recommend her enough.
