Erin Proulx's Reviews & Ratings

Tell us about your experience with Erin Proulx

    • Portsmouth NH | Single Family Home | Listing | Closing Price: $464,550 | Erin is an expert and professional in the field. Erin listed and sold our house, while finding us another house to purchase at the same time. Both transactions were seamless and we couldn't be happier with the result. Communication was great throughout the process from Erin and her team, and we hope to use her again down the road!

    • Hampton NH | Listing | Condo | Closing Price: $530,000 | We had previously listed our condo with another realtor. We had no offers in 6 months. We listed our condo with Erin Proulx at the same price and had a signed P&S in only 2 weeks. There were several improvements compared to the prior realtor. She provided advice on small changes to make our property stand out. Erin used marketing techniques (including social media) to drive traffic to the Zillow web site. She used great pictures including those from a drone and a virtual tour linked to the listing. Erin provided continuous feedback on the status, schedule of planned activities and results. We highly recommend Erin and her team.

    • Portsmouth NH | Single Family Home | Buyer | Closing Price: $610,000 | We had both the opportunity to sell and buy with Erin, and I couldn't of asked for a better realtor to help us through the process. Selling was not an easy decision for us as we fell in love with our place and the neighborhood, but we had quickly outgrown our space. She was very patient through the whole process and respectful towards our feelings. Erin also put together a pamphlet for our prospective buyers highlighting the gems in our area. When it came time to buy, we were in no rush as we searched to find our forever home. Erin contacted us any time she found a place that fit our requests and was very flexible when it came time for looking at homes. I am very happy to say that with Erin's persistence and expertise, we were able to find our forever home in one of the best neighborhoods Portsmouth has to offer! Thank you to Erin for sticking by our side through the ups and downs and for the ease of the entire process. Her professionalism and hard work are just a few key qualities that make Erin such an amazing realtor!

    • Portsmouth NH | Condo | Buyer | Closing Price: $620,000 | Working with Erin to buy our first home in Portsmouth was an absolutely amazing experience. As first time home buyers, we didn't really know what we were getting into and Erin made the process SO easy. She answered all of our questions thoroughly right away. Erin was up front and gave realistic expectations about what to expect, while still making the process super fun and exciting. I highly recommend Erin!

    • Portsmouth NH | Condo | Buyer | Closing Price: $620,000 | My wife and I worked with Erin Proulx a few months ago as we looked to buy our first home in the downtown Portsmouth area. Erin made the first time home buying experience seem EASY. She had great knowledge of the local Portsmouth real estate market, helped us through the first time home buying journey, and did a fantastic job in the negotiation process, helping us get a great deal on our new home. We recommend Erin to all our friends looking to buy a home in Portsmouth!

    • Portsmouth NH | Condominium | Seller | Closing Price: $630,000 | Proulx real estate is one of the best! Erin helped us buy our first condo and when it was time to start our family helped us buy our first home. She excelled at everything. She helped us hire an amazing painter to come freshen up the place, gave prompt responses, and fully kept us up to date on showing results for our condo. The pictures and video taken were very professional and show cased all our condo had to offer a buyer. She takes pride in everything she puts her name on!!! When it came time to finalize our move, her team was there to help us every step of the way. I cannot express how smooth the whole transition was! Five stars all around.....and when the time comes for us to retire and down size we will be calling again!!

    • Strafford NH | Single Family Home | Listing | Closing Price: $355,000 | We used the Proulx team to sell our home last month, and I cannot say enough about how amazing they were to work with. They were responsive to my inquiries, kept up with approaching deadlines and acted in our best interest. Erin was always good about presenting us with all the options and her thoughts for us to make the most informed, best decision. I would highly recommend them, and look forward to our next transaction with the Proulx team!

    • North Hampton NH | Single Family Home | Listing | Closing Price: $690,000 | Erin provided exceptional service, getting several above price offers on my house 3 days after it went on the market. She guided me through staging, marketing and pricing. Her entire package included a professional video and photo package, advance "coming soon" marketing to zillow and other outlets, and an open house. Her office is well coordinated, taking advantage of online documentation and electronic signatures, scheduling and communication. I highly recommend Erin and her team.

    • Portsmouth NH | Single Family Home | Listing | Closing Price: $577,500 | Working with Erin Proulx to sell our home was quick and painless! She had the whole process well orchestrated and everything came together perfectly. The photos were carefully planned and beautiful. Sue Murphy, her assistant, worked hard behind the scenes answering all our questions and being at the house as needed. I would highly recommend Erin to anyone looking to sell their home.
