We absolutely recommend David Santini 100%. He is extremely professional, patient, fair and so supportive . We are so happy that he was our agent through the very stressful project of selling ones home. Eileen Faherty David Santini
Mike, Just to let you know that hiring you to sell my house was one of my better ideas, it was a pleasure working with you. You are truly a professional of the old school, extremely helpful in setting the house up properly, advertising, and selling it in short time. In the process as I got to know, you you became a friend and always will re main that. Here are a few pictures of my new home. Your friend Gerd Michael Santini
To Whom It May Concern I just wanted to 'Thank', one of your agent that I worked with recently during my first home purchase. He is no other than Matthew Tatro! Matthew started this journey with me back in 2016 , when I had decided I needed a home. I was contacted by him and we began our journey back then. Matt had the time and patient with every single house he showed and displayed a very honest feel about the way he see's a home for his client and he knows exactly what you want in a home and stick to that , so when you're out with him , there is no wasting of time. However with that being said, I did not purchase any property in that year, we started again in 2017 and yet the same! But it finally happened this very June of 2018 :) Matthew did an excellent job overall! He did not loose hope that I would find what I needed and shop with me for my home as if he was making this big purchase for himself. When I had questions , he was very responsive and did not delay. He takes his job seriously is willing to go the extra miles just to make sure that at the end of it all his client is happy ! I will surely recommend Golden Key Realty and of course Matthew Tatro to family and friends looking to purchase a home. Thanks once again to your Agent "Matthew Tatro", without his help it wouldn't be possible finding this perfect home :) Your's Truly, NEETA SAMPAL Matthew Tatro
Mike was excellent to work with as our listing agent for the sale of a home we inherited. He is very knowledgeable regarding the local housing market. He did a great job setting expectations for us and making sure the process was smooth. We were remote, out of state, sellers so Mike's personal approach was re-assuring. We were very pleased with the entire process and results. K. Seip Michael Santini
Mike Santini is one of the most honest, courteous realtors I have ever dealt with. I can only speak from my experience, he went above and beyond for me. I had a difficult situation and Mike made me feel it would all be fine. All he said was "Trust Me" which was not an easy task because I had a previous realtor that was taking advantage of my situation. Mike becomes personally involved, he became my friend, my protector and truly had my best interests at heart. I was a divorced mother with a home that was strapping me not only financially but, mentally and emotionally as well. When would have the occasional meltdown, Mike would say "stop worrying, let me do my job". It took some time but he was a man of his word and sold my home and then helped me find another rental. I would sometimes laugh because we would go look at a place and he would walk in and say "Oh no! This is not the place for you " and we would walk out. Who does that! Most realtors in my experience want the commission, not Mike, he wants what is best for his client. I still to this day reach out to him with questions and he is like talking to an old friend. Always there and always helpful. Mike Santini is far more than a broker/realtor, he is a king among men! (At least in my opinion)" D. Jablonski Michael Santini
I was introduced to Golden Key Realty 7 years ago when I was going through the unexpected loss of my husband and trying to manage a rental property from 60 miles away. Marguerite Caruso was amazing in helping me navigate finding reliable tenants and learning the expectations of a landlord and the municipality. She always went far beyond her role as my realtor and has been consistently supportive and incredibly knowledgeable in all aspects of real estate. I HIGHLY recommend Golden Key and without a doubt would recommend Marguerite Caruso!!!

We needed to sell our family home in Piscataway when my mom moved out after 55 yrs. I was referred to Dave Santini, and without-a-doubt, he was an amazing agent. He is a great communicator and was always easy to connect with. He has an excellent referral network of similarly exceptional help for inspections, remediation, repairs, legal, and anything else that comes up. Dave when above and beyond the call by going to the house when I couldn't (I live in Virginia) and doing everything from swapping documents to fixing a toilet for the walk-through. I've been a landlord and real estate investor for over 10 years. I would not hesitate for one second to have Dave Santini on my side for ANY real estate transaction possible. We got an offer within 30 days and closed in 60. This is a 5-star professional. Kent Mack David Santini
Dear Dave, There are no words to express our gratitude for you between the craziness with the Hillcrest house and the craziness with this house. You have been beyond amazing. Thank you for everything you have done. You have been a realtor, bartender and drinking buddy, part time therapist but most importantly, our friend. We could not have gotten through this process without you. You are an incredible person inside and out. We will continue to praise you and shout your name from the rooftop to anyone looking for a home. Also, you will forever be our go-to guy! You are so sweet, kind, helpful and wonderful and we feel so blessed to know you. Thank you again from the bottom of our hearts for all your help and hard work!! You’re a Rockstar! Can’t wait to have you over! Sincerely, Mark Lauren and Palmer David Santini
After my mother passed away in March 2015 I knew I had a big job ahead of me emptying 68 years of living in her home. When I asked Marguerite Caruso to sell Mom's house I knew she would put her all into it. That's her work ethic. From beginning to the closing. From suggestions of how to dilute the contents, staging the house for the best brochure pictures, and deciding on a realistic selling price. The house was bought by a couple who absolutely loved it. My parents home served its purpose for many years and now was ready for the next family to it make it their home. Then.....in 2016 I wanted to sell my condo. No doubt Marguerite used her professional skills once again and we sold my home $9k more than I purchased it 5 years before. If I had another home to sell Marguerite is the gal I would call. She and the Golden Key staff make every effort to ensure their clients are delighted when selling or buying a home. Eloise Sicora Marguerite Caruso
Darlene goes above and beyond. We were so lucky to have her as our relator! She was so patient with us! She showed us alot of houses and never gave up on us. She kept telling us we would find the perfect one and we did! Thank you Darlene Darlene Lilly
