Heather Douglas Mayer - Associate Broker

Heather Douglas Mayer

Associate Broker


I joined the real estate industry in 2011 working at a Yarmouth-based title company, which proved invaluable in helping my clients navigate the final steps to closing. More
importantly, it sparked my passion for real estate!

After working at a large franchise on one of the highest producing real estate teams in New England, I joined Portside, where the client-centric approach and personalized marketing has enabled me to double my business every year.

I was one of six agents recently inducted into Portside’s Circle of Excellence, a select group of top performers within the company. In addition, I was thrilled to realize I was in the top 1% of Cumberland County agents based on volume sold for 2018. My commitment to giving back to the communities I work in is very important to me. As a Realtor, I have served on the Greater Portland Board of Realtor’s Habitat for Humanity Committee and regularly participate in opportunities to volunteer for Greater Portland non-profits.

The world of real estate is constantly changing, and I actively seek new ways to continue my education to better serve my clients. I am a member of the Women’s Council of Realtor’s and recently achieved the Green Realtor Designation.

I attribute my success to my strong work ethic, responsiveness, and genuine desire to help my clients in every way. I look forward to helping you!

What do you love most about real estate?

“ Simply put, I enjoy helping people. The purchase and sale of real estate is one of the biggest financial transactions most people make and it can be a very stressful and complicated process. Going the extra mile to achieve a successful real estate transaction for my clients is immensely rewarding to me. ”

"Heather was a pleasure to work with in every way. What drew us to her initially was her warm, friendly manner, and her creative ideas on developing a custom-tailored marketing strategy for us. She really listened to us, but also added her own knowledge and advice - very valuable. She was always responsive and encouraging as she guided us throughout the sales process. Great work, Heather. Thanks!"

Peter G., Yarmouth

"Heather came over to our house that we had been thinking about selling - and the next thing I knew - a SOLD sign was on the front lawn! She is not just a great salesperson, but very creative in marketing strategy. She gave us clear ideas of things  we had to fix and things not to worry about - her advice was excellent. She guided us through any little bumps in the process and we had a nice uneventful close - thanks to her incredibly professional guidance. If you want someone who will actively work for you, and really try to understand what you need - you will want to hire Heather!"

Mary Ann S., Portland

"Heather knew exactly what I was looking for in a home and was very proactive and responsive. She was able to get showings that fit my schedule and was always professional and informative. I highly recommend Heather as a Real Estate Professional."

Stacey F., Falmouth

"We had the pleasure of working with Heather this past year. She is amazing. Her attention to our wants and needs in a home were remarkable. She provided us with new listings that met our list of wants and was able to accommodate our work schedule. Her negotiation skills are impressive. She lobbied  on our behalf and kept us informed every step of the way! I would definitely call Heather with whatever real estate needs you have."

Jean S., Windham

"Heather is a breath of fresh air. She is extremely knowledgeable about real estate and openly shares that information with her clients. Heather notified me of a property within hours of its listing, managed to get me in for a showing before the sun set, and the sellers accepted my offer within 12 hours. In this hot real estate market, she's the person you want on your side."

Kate G, South Portland

"You want Heather as your realtor!  She helped us find our dream lakeside property and we were NOT easy to please!  Heather stayed on top of listings to be sure we were first to see potential, new properties.  She was very knowledgeable throughout contract negotiation and facilitated all scheduling of inspections, testings, etc..  Right through to closing, Heather got all our questions answered and provided information on the property we didn't even know we should ask for!  She is smart, professional, upbeat and will work tirelessly to find your dream home."

Shawn C & Shelly C, Falmouth

"Heather is an exceptional realtor. She is thorough and detail-oriented, but it is her warm and outgoing personality that puts her a step above the rest. She understands the local real estate market and, with her guidance, we were able to sell our house quickly and above our asking price. I recommend her wholeheartedly."

Kate and Kris P., Yarmouth

"Heather Douglas was the realtor we used when we sold our house, and when we bought our next house. She was instrumental in having our house sell quickly, we had multiple offers in the first 48 hours it was on the market! She gave us many suggestions on how we should prepare our house to be sold, and our house looked beautiful and inviting in the professional pictures shown on-line, and at the open house. We had many questions throughout the selling process, and she was very patient and answered our questions thoroughly. We don't know if our house would have sold so quickly without her guidance and suggestions. After we sold our house, Heather helped us to find our next dream house! We were particular about what we were looking for in our next house, and Heather showed her extreme patience again with us, and helped to guide us in the purchase of our new home. She was very knowledgeable with the negotiating process, and really looked out for our best interests when dealing with the issues that can arise in purchasing a new home. We would highly recommend Heather for anyone interested in selling their house or buying their own dream house!"

Tammy and Bob S., Windham

"Heather was extremely patient with us as we worked through the process.  She was very proactive in finding out what types of properties we would potentially be interested in (styles, price range, location etc.) and sending information on homes that might fit our needs.  This took months, as we were  waiting to sell our existing home, and Heather maintained the exact right amount of contact with us (not too much, not too little).  She was positive, excited and committed to finding us the exact right fit - which she did!  She was an extreme pleasure to work with...We felt this was not a "sale" for her but that she truly wanted to find us a new home that we would be 100% satisfied with.  And, she was just as excited as we were when she accomplished that goal.  Without hesitation, we would definitely seek out Heather again for future real estate transactions."

Darci H., Yarmouth


"Heather is an amazing and professional agent.
She assisted with the purchase of our first home in a very competitive market.  Heather successfully excecuted the acceptance of our offer and confidently lead us through the process.  
As first time home buyers, we needed some extra information and  attention.  Heather exceeded expectations in meeting our needs; even the needs we didn't know we had!
Heather shared our eagerness and excitement while providing sound advice and displaying excellent knowledge of the realities of the real estate market.
I would strongly recommend Heather to anyone buying any real estate at any point in their lives."

Jaimie L., Yarmouth


"Heather was awesome to work with. Very quick to respond and always kept us up to speed on how things were progressing. She was patient with all of our first time homebuyer questions."

C. H., Gorham


"Heather was a real pleasure to work with!  She was well organized and very knowledgeable.  She kept us informed frequently throughout the process which was extremely helpful.  I would highly recommend her to anyone seeking out a new home."

Chris P., Scarborough


"Heather Douglass is a super star! She guided us through the difficult process of selling our home and buying a new home at the same time. Heather is extremely prepared, knowledgeable, and always stays level headed through what can be an emotional process. My family could not be more happy with our  new home; and we feel without Heather we would not be there. I would highly recommend Heather Douglass; she will not disappoint!"

J.M., Cumberland Center


"For a first time home buyer, Heather made the process of buying a new home incredibly smooth.  She was helpful every step of the way and always accessible for questions and provided good insight.  Highly recommend!"

Chris B., Yarmouth


"Heather is an incredible agent. She was dedicated and motivated from day 1. She was in the loop about listings before they even hit the market and constantly networking to try to find the best home for us. Additionally she is incredibly knowledgeable about home construction in general and knows what  to look for in a good home. We entered an extremely competitive market and were nervous to sell our home but we did (which she did for us in 3 days) and with her help we had an offer accepted our new home within a month. There is no one else we would have trusted more to sell our home and help us with a purchase of a new home than Heather. Ontop of it all she always answered our questions right away and was patient with us throughout the process. We're so thankful she was by our side for this crazy, exciting journey!"

Amy M., Cumberland Center


"As a first-time home-buyer, I had very little experience with shopping for homes, comparables, negotiating an offer, and all of the million other ins and outs of real estate. However, it never felt stressful or overwhelming because Heather was extremely helpful every step of the way. She always had  prompt follow-up on my questions, maintained unbiased and professional opinions, and made sure I always had all the information I needed to make educated decisions. She was extremely great to work with and I would recommend her for anyone looking to buy or sell in the southern Maine area."

Rachael M., Westbrook

"Heather was absolutely phenomenal and we would recommend her to ANY seller or buyer. We were first time home buyers, and she always made sure we were well educated and informed on all aspects of the process. She was on our side fighting for what we wanted and making sure we got the best outcome.  She was so personable, trustworthy, and was ready to brave snowstorms for us in this crazy market! I couldn't imagine going through this process with anyone else."

Taylor B., Windham

Heather is an all around fantastic agent. In preparation prior to us hiring her she came with a very thorough market analysis and confident direction for selling our home. Through the listing process and eventual sale of our home her dedication remained outstanding and consistent. She was  available, responsive and motivated. She truly made the process as painless as one would hope but also helped ensure she met all our needs along the way."

Tammie M, North Yarmouth

"Heather was a great help in finding my first home and she was very helpful throughout the whole process. From house hunting to the closing she was in constant contact and made sure I understood the entire process to buy a home."
A.C., Windham

"My wife and I feel so fortunate to have found Heather to guide us through our first home buying experience. She is enthusiastic, warm, and professional and it was great to work through this potentially overwhelming experience with her as our leader. We feel that it was due to her strategies, market  knowledge, and advice when drafting our offer that we were able to beat out five other offers to successfully purchase our new home! Her detailed communication led us through the inspection and closing as smoothly and efficiently as possible. We cannot find words to express how much we recommend Heather, you just have to work with her yourself and you’ll agree."
JF & LF, Yarmouth

"Heather just helped us buy a beautiful home in Maine -she was amazing and made the whole process as smooth as possible! She is a true professional and was there for us every step of the way to answer any questions and help us negotiate a great price. Even when I’m sure we drove her crazy, she had  the patience of a saint! You will love her, she is truly awesome and we recommend her 110%!!!"
H.A., Windham
"Professional in ALL respects. I think of all things, she really listened to what Peter and I were looking for in a home. We have bought and sold 7 homes in the Northeast and of all the realtors we have worked with, Heather is truly a shining star.   **** please note that Heather worked with us for approx. 1 and1/2 years to find our perfect home."
J.S., Brunswick

"We are so lucky we found Heather! We met her at an open house that she was the listing agent for and her relaxed, no-nonsense attitude is exactly what I wanted in my own agent. She is always quick to respond and we never had an issue viewing a house quickly. She really took the time to understand  what we needed and made sure we weren’t wasting time looking for options that weren't going to cut it. When the perfect house In the perfect place popped up (months before it actually came on the market) she contacted us and we got to work making sure we were positioned to get it. A well written letter, a perfectly structured offer, and three days after coming in the market, we had a house! I’m so grateful for Heather and all that she’s done for our family!"
"We bought a property in Cumberland, Maine and benefitted greatly from her expertise in the various aspects of managing the purchase, from help with arranging viewings, negotiating a price and contract of sale, arranging inspections, advice regarding financing (we are  immigrants with no US credit history) and recommending tradespeople. Heather went above and beyond our expectations by playing an active role in helping us terminate our house rental lease agreement."
M. Roger
"We couldn't have asked for a better realtor. I began speaking with Heather a year before even making the move to Maine and she was always prompt, professional and very knowledgeable. Highly recommend!"
