Erin helped me and my family through a stressful negotiation for a very unique property, and together we were able to close on my family's dream home a few days early. Erin knows the Cary market extraordinarily well, has an amazing network of contacts, is wonderful to work with, and gave us excellent advice. I would highly recommend Erin and the Gassesnsmith group to anyone looking for a realtor in the Cary area.

Erin was recommend to me by my daughter-in-law. From the moment I met Erin up to the close of my home, she was professional, knowledgeable and handled ALL the details. Erin communicated well with the home inspector, my lawyer and the sellers agent. As a buyer, I know Erin acted in my best interest and the whole process was stress free because of her expertise. Thank you Erin!

When I decided to downsize I had lots of questions. My next steps relied on what I would net from the sale of my home, timing, and flexibility with a closing date. Erin assisted me every step of the way…from preparing a market analysis, explaining the contract, and acting as liaison between me and potential buyers. In the end, I received a full price offer and terms that fit my needs perfectly. Erin’s professionalism and knowledge of the industry are exemplary and I would not hesitate to recommend her for your future real estate sale or purchase.

As first time homebuyers, we were overwhelmed and had so many questions throughout the process. Finding the right home for us was truly a roller coaster as we were in a tough market. However, Erin was so reassuring every step of the way and truly became our trusted advisor. She was so patient in showing us so many homes and never making us feel rushed to make a decision. Thanks to her reminding US to stay patient and not force the process, we ended up in the perfect home for us and I’m so thankful!

We were making a long distance move from FL to Crystal Lake, IL. Erin assisted with every aspect of our move, from helping us find a wonderful realtor in FL for our sale there to finding a local moving company to assist with our move. We ultimately decided on new construction In Crystal Lake and Erin was here for us every step of the way. She attended meetings with our builder, helped us find a lot, assisted with choosing inside and outside finishes, sent us construction updates and photos, and even attended our final walkthrough. The entire process went very smoothly and the timing for our move was perfect. Erin’s knowledge, patience and professionalism made our difficult move seamless! Thank you, Erin!

Erin was a delight to work with. Her personality is always positive and she was very accommodating when it came to working with my schedule. Erin is very knowledgeable. Mine was a Condo purchase instead of a house and Erin knew all the subtle differences with contracts, insurance and HOA fees. Erin also was very helpful when questions arose with my realtor in Wisconsin handling the sale of my house. She was always willing to make that extra call just to confirm information. I would highly recommend Erin as your next realtor!

Erin was professional from the first phone call I made to her through closing. She provided a well thought out, detailed plan to get our home listed at the right price and sold quickly. We couldn’t be happier. We received offers within days of listing. We ran into some issues along the way with an offer that fell through, but Erin always stayed positive and kept us up to date on what was happening. She went on vacation shortly after listing our home, but made sure to put us in touch with another realtor In her office that was always just a phone call away and answered all of our questions/concerns promptly. I would definitely recommend Erin! She definitely made the whole process less stressful. We can’t thank her enough

When my husband decided we were putting our home on the market the first thing I thought of was, do we have to? And secondly, boy, how much work will this be?! After purchasing our last home from a bank back in 2008, we knew things have changed dramatically in the real estate market and we asked Erin questions throughout the entire process. When our home sold after the first viewing (a bit shocking and exciting!) she immediately lined up 15 houses for us to see and we found our perfect home shortly thereafter. Erin made writing a contract, putting in the offer, negotiating, and ultimately awaiting the great news on our new home super easy. She made sure both the sale of our home and the purchase of our new home lined up on the same day, dealt with all parties, attorney’s, my mortgage broker and the title company to make sure the process was easy on us. She’s very knowledgeable, has a great personality, charismatic and always had a smile on her face. She helped us in the beginning with staging our home for the sale until the very end being physically present at the closing, following up with answers to our property tax exemption questions and was just a delight to work with. My husband and I knew she was working for and with us, gave us her honest answers and had an objective opinion throughout. I STRONGLY recommend working with Erin Matthews if you are looking for a realtor!

When I went to look for an agent, the neighbor across the street from me gave me Erin's name. She sold their house before going on the market and she also sold my house before it hit the market. Erin handled every detail and kept me up to date on everything which was nice, since I was never in town. I highly recommend Erin! Rick Hunt

Erin was the best thing that happened to us during this process! She gave clear, honest guidance and negotiated an amazing deal for us. Her skills, knowledge, and experience made the buying process incredibly simple. She was so responsive and communicated with us every step of the way. Erin kept our needs and wants at the forefront, ensuring that we found our perfect forever home at a fabulous price. We couldn't be happier! What's more, she sold our old house in just four days-at full asking price! She even helped us navigate the complicated selling process, which we'd never done before. She made it easy, quick, and beneficial for all parties. You can't ask for more than that. We're recommending Erin to everyone we know! Thank you, Erin!

Thanks Erin, we love our home!
