It is my pleasure to recommend Dan Castle to be your realtor. Dan recently helped us to sell our property in Westfield,Maine.

Dan listed the property, priced it based on current market values and sold it shortly after for more than the asking price.

He then facilitated the processes needed to complete the transaction with great people in the area and I was able to collect payment a short time later.

Dan Castle and the Next Home Discover are top shelf performers.

Dan Castle was a great broker for the recent sale of our lake house! He was in contact frequently, gave us an honest opinion about our property and created nice photos, video and 3D on MLS. Everything went without a hitch. I recommend Dan to others interested in the sale or purchase of real estate!

We were relocating to Maine and reached out to Dan to help us find a property and boy did he! He found us the perfect property in the perfect location. We have bought and sold numerous properties in the past and Dan’s communication, expertise and knowledge of the area far exceeded our expectations. We highly recommend him and his team for any real estate transactions. If you are buying or selling call him today you will be glad you did. We can’t thank him enough

In my opinion Dan Castle is the best realtor in Aroostook County. He is very knowledgeable in the local market, works hard for his clients, gives very fair valuations of your property, markets outside the local area to give you the most potential for buyers, is kind, and very professional. This is the second transaction Dan has helped me to complete since I moved to the area 4 years ago, and everything went as planned both times.

Dan stands out from the rest. I been looking for a year now for the perfect piece of land. I spoke to many realtors and none stayed in touch and followed up as they said they would. I live far from the area and Dan has been out in the field and walking in the woods for me and even taking drone footage for me. Finally he has found what I was looking for. He has gone above and beyond anyone that I've ever dealt with. Thanks Dan , don't ever change. Your great at what you do.

Dan went above and beyond to give me piece of mind that he was on top of things. He helped work out a deal to help the buyer get the financing needed to make the sale. Thanks Dan!

When we first met Dan, he explained the selling process and how his job is more service than sales. He proved that time and again with his thorough knowledge of home construction and the local market. When we saw our listing we were blown away. His hard work and knowledge of what it takes to sell a home really paid off - our listing looked amazing. Our home went under contract in a little over a week. I realize it won't always be this easy to sell your home, but I think you'd be hard pressed to find a better Realtor. He was extremely responsive and very pro-active on communicating with us, with our many questions. I wish I could find some criticism to help him better himself in his career, but I honestly can't think of anything that he could have done differently or better for us!

Highly recommend Dan for all your real estate needs! He flawlessly assisted us with a land/building purchase that closed within 3 weeks.
He also had another property of ours under contract the same day it was listed and we are currently using him again for another property we are selling. Dan has always gone above and beyond for us!

Dan is motivated and we worked very well together on the sale of our home. In the middle of a crazy time we did it, as far as I'm concerned Dan has a bright future even though these times with everything working against the people. Believe me he's the one you want in your corner with the way things are today. Thanks again Dan, blessings to you and your family.
