After interviewing three other very competent Agents, we ultimately landed with Ann Castonguay of Sprague and Curtis and are so grateful for it. Ann brought the exact mix of expertise in the field, a very impressive local knowledge of the area, and a tenacity/work ethic beyond expectations. She met all of our needs as a the seller. We are so happy with the result and it is largely due to Ann's guidance and professionalism. We can't recommend her enough.

A Five-Star ExperienceaEUR"And Then Some! My wife and I have worked with professionals from all walks of life, and I can confidently say that Ann Castonguay is, without a doubt, Maines best Realtor. If we could give her more than five stars, we wouldaEUR"without hesitation. We recently made the decision to sell our lakefront property, nestled on 26 stunning acres. This was more than just landaEUR"it was part of our story. Entrusting someone with that kind of sale required more than a license and a smile. We needed someone with insight, professionalism, and heart. Enter Ann. From the moment we met her, Ann brought a calm, confident presence that immediately reassured us we were in excellent hands. She dove deep into the details of our propertyaEUR"meticulously researching its features, location, and value. Determining a price point for a unique piece of land like ours is no small feat, but Anns strategic market insight helped us land on a price that proved to be right on target. What truly set Ann apart was her ability to articulate the essence of our property. The listing description she crafted was nothing short of masterful. In fact, the buyer told us at closing, aEURoeThat description is what caught my eye. I just had to see itaEUR"and it was exactly as you described. I am going to copy and frame that desciption and post it one the entrance wall of our home for everyone to see that we found our dream property.aEUR? That speaks volumes. And the result? We listed in FebruaryaEUR"and by June, the deal was done. We had high standards. Our previous realtor had retired, and we werent sure wed ever find someone with her same level of tenacity, creativity, and professionalism. Thankfully, we found all of thataEUR"and moreaEUR"in Ann. She exceeded every expectation. To anyone in Maine who is thinking of buying or selling real estate: Hire Ann Castonguay.

Ann was incredible. She was so patient with our family and littles when we viewed homes. She made sure to listen to what we wanted and found us the perfect home. She can be known for her professionalism. She made us feel like every home would be a perfect fit, but listened to our wishlist. We are so blessed we had the opportunity to work with her.

Because of the virus, I had to do my entire transaction remotely. Ann was a tremendous help. She gathered information from seller and neighbors. She referred me to inspectors and contractors. Most importantly, she got right back to me when I texted or emailed. Could not have gotten this wonderful Maine home without her exceptional support. Mimi G.

Ann helped sell my father's house after his passing. I was out of state, and Ann kept me up-to-date during the process and helped the entire process go smoothly. She helped keep an eye on the property while it was for sale, helped arrange for the property to be cleaned, and helped me with recommendations when the septic tank needed to be pumped. I would definitely work with Ann again.
