Our Latest Clients' Comments

-Joe represented us in a lengthy international home purchase. He was patient and continually answered all of the questions which arose. When the right location was found and the final price settled upon, we found an email from 24 mos prior in which Joe had identified what fair market price was. We ended up at that price which was some $200k less than the seller was asking.

-Joe is a person who takes care of everything. He works together with local people to make things more efficient. He keeps track of details and even after years knows the market very well.

Michael Falter

Joe is by far the best real estate agent on the Cape. I had worked with other agents prior to working with Joe that seemed to treat real estate as a hobby. That is absolutely not the case with Joe! He is very knowledgeable, engaging, professional and most importantly patient. Joe spent a lot of  time with us on our journey to find our perfect vacation home and we couldn’t be happier with the guidance Joe gave us and the great job he did negotiating the final price. If you’re looking for a realtor on the cape to either help you buy or sell don’t waste any more time either looking for an agent or working with a mediocre agent, work with Joe ASAP.

Russ & Jenn Jackson

Joe is the best real estate agent on the Cape. He responded immediately to all of our questions and concerns and followed up when the answer or solution wasn't readily available. He listened to our "must haves" and found us a property that had everything we wanted and was within our price range.  You can't go wrong hiring Joe, he will work tirelessly to get you exactly what you want.

John & Stacy Kanaga

“Joe not only helped us find and purchase our second home, he listed out first.  He took us on dozens of showings, and negotiated an excellent purchase for us.

Joe also listed out first home that was a pretty difficult sell.  We listed only days before we had 3 straight months of 20+ inches of snow.  He aggressively marketed the listing, and was tireless with showings and open houses- always quick to provide us with feedback on results.  He was very respectful of our schedules and gave good advance notice of showings.  He was a tough negotiator with buyers, and ultimately landed a difficult/tricky deal.  I have no doubt we ended up with the absolute best deal we could have gotten, and if it weren’t for his incredibly hard work, it would have taken much longer to sell the house.”

Jess & Chad Thomas

“My wife and I were fortunate enough to meet Joe and enlist him as our buy-side agent. Joe was wonderful throughout the entire process and assisted us in every area that we needed. He is very knowledgeable about the towns of Cape Cod as well as the entire process of purchasing a home. He is easy to contact and his response time was always within 24 hours if needed. The process of purchasing a home can be stressful, but Joe was able make the process smooth.

I would highly recommend Joe to anyone that is in need of real estate services. Although we used him to purchase a home, I am sure that his expertise and professionalism makes him an excellent sell-side agent as well.  If and when my wife and I decide to move on from the home we just purchased, we will definitely return to use Joe as our agent.”

Nathan & Samantha Hall

“Joe was nothing short of fantastic. This was not our first experience with an agent and Joe outshone the others with whom we have worked. He listened to us through every step of the process. He worked to understand our needs, our preferences and our goals. He was attentive throughout. Joe was patient and never pushed or rushed us. When it came to the negotiation process, he added genuine value. He provided both data and guidance that insured that we got what we wanted at a fair price. Joe was professional in every aspect of his work with us. We would recommend Joe to both buyers and sellers without reservation. He is professional, fair, patient and above all paid very close attention to our goals in the process. He did not "sell" us a home. He assisted us in our process of "buying" a home that met our needs on all levels.”

January 2015- David & Donna Condon

“Excellent knowledge of the area and details needed to complete transaction. Complete professional. Very thorough with great follow up which is so needed in todays challenging mortgage enviroment. Would highly reccomend him to anyone looking to purchase real estate on lower Cape Cod.”

January 2015- John Gauthier

“As always, being a first time home buyer is an intimidating and stressful experience. Joe worked with me patiently for over a year, as I became more comfortable and knowledgeable with the home buying process. Joe was always a phone call away, day or night, answering my many questions and performing follow ups on the properties I would inquire about. He quickly became in touch with what I was looking for in a property. Which would change regularly because it was all so new to me, but Joe never skipped a beat and professionally adapted to my changing views. I highly recommend Joe Hartung and will always consider him my relator.”

October 2014

Joe Bono

“We had Joe list our house in Harwich. He came well prepared and presented all the comps, and gave us a good evaluation of the house. We listed and were under contract in a very short time. Joe did the legwork through the entire process setting up all our needed items (contractors, documents, etc). Joe also set up and took us through many showings to find our perfect home. He was very well prepared to talk about the neighborhoods, the houses and the community in general. He showed much patience in the back and forth negotiations on both properties. In all, Joe was very responsive, supportive and knowledgeable. We would highly recommend Joe.”

"I could not have been happier with my experience buying a house with the help of Joe. He expertly navigated us through the home buying process. When a few possible issues arose, Joe handled the other party with a level of professionalism and poise only obtained through a true dedication to his work. He contacted us immediately and continued to keep the communication flow going. I have continued to recommend Mr. Hartung to my friends and others, and will use Joe again if a real estate transaction is needed again in my future. Thanks Joe." -Paul L. March 2014

We hired Joe Hartung to sell our condo. He was always very professional in dealing with each situation. When the right client came along, Joe made sure that all aspects of the sale were completed to the buyer and our satisfaction. He was a pleasure to work with and we wish him much success in his future. -Jane T. December 2013

"Joe, Carried the ball throughout the purchase of my home.  Joe knew what was needed, provided names & contact info for the additional people needed along the way, made sure I had everything that was needed and was present at all critical junctures. I recommend Joe for a trouble free transaction of buying or selling a home."   -Patrick O.  Fall 2013

"I worked extensively with Mr. Joe Hartung, of oldCape Sotheby's Brewster office, from both overseas and while on the Cape in purchasing a home there.  He was quite personable, always very accommodating, extremely punctual, organized, knowledgeable about the local market, had good working relationships with his fellow agents and with the local vendors for obtaining timely repair bids and inspections, always returned his calls, and promptly handled all necessary paperwork and loose ends, even after closing.  And never was  there a complaint from him, even after I led him down numerous dead ends.  In sum, it was a delight to work with Mr. Hartung, and he is highly recommended for your consideration."                       -Darryl Fanelli, October, 2013

"Joe was very professional. Very responsive and had great attentive to detail. He kept us up to date and well informed with all details. We were very happy with his effort, expertise and most all results." -Ted C. August 2013

"Joe was very supportive in the transitioning of our mother from her single family home to new residence nearer to us.  He was empathetic, responsive, flexible and attentive to all details throughout the entire listing, marketing and closing process." - Kathy D.

Summer 2013

"Working with Joe was a true partnership. What sets him apart from the rest was that our family's needs were his highest priority, we never felt there was any other agenda for him. His openness, humor and pragmatic approach made a typically stressful process enjoyable and rewarding. As a local cape codder, Joe was knowledgeable of the market as well as how to get the information we needed to make a confident buying decision. In the end we not only came away will a beautiful home but a friend as well." -Danya N.
