I have had a pleasure to work with Mike on the purchase of my new home as well as selling my first house.  He was always professional and willing to go the extra mile to help his customers.  I never felt I was his client but someone of his own family.  He is genuine and honestly takes care of his clients.  I would highly recommend Mike and his agency and I would keep him as my resource!  Arsalan Michael Santini
If you're looking for a realtor who will give you the personal attention you need to buy a home, Dave has to be your guy! Dave treated me like a family member. He was always available through text or call and he guided me through the process from day one. Dave quickly understood the qualities we were looking for in a home and gave honest opinions about the homes we visited. That honesty shows he isn't just looking to make a sale. He truly wants to put you in the home that's right for you. Once we decided on a home Dave provided me with excellent recommendations for loan services and lawyers, who also treated me like family. Can't recommend Dave enough! Scott Phillips David Santini
My family and I are blessed to have connected with Mike. We started the process of selling our home in March, when Mike came to our home. This was our first time as sellers and we were certainly green. Mike carefully walked us through the process and provided a check list of items to complete in order for our home to sell. We carefully followed his suggestions to the letter and listed our home in late April. Within 9 days, we received a full price offer! After a quick negotiation post-inspection, the sale of our house was settled and we moved on towards find our dream house. Much like the selling process, Mike was in constant communication as we explored the 08822 zip code. Mike's advice and insights were proven correct each and every time. We were able to negotiate and close on our perfect house the same day as the sale of our existing home. What was in theory a stressful process was made much easier through Mike's patient counsel. We trusted Mike implicitly and that trust paid off. Mike is now an extended member of our family. We will be forever grateful for all he has done for our family. We recommend Mike without reservation. He is the best! Derek Weber Michael Santini
He helped us buy our dream home and helped us sell it 26 years later. It’s hard to find a friend like this not to mention a realtor like this! Mike is the BEST! K. Rath Michael Santini
Dear Margie,
Just a note to tell you how thankful Ed & I are that you were our Realtor in the process of selling our home. As I told Mike, you went above and beyond what is expected of a Realtor.
Your kindness, thoughtfulness, consideration and compassion were wonderful. And, let's not forget that you are very knowledgeable in the rules and policies of real estate.
We wish you continued success in your career in real estate.
Most sincerely,
Terry & Ed Schurdak
P.S. Thank you for getting us from day #1 to final closing.

We works tirelessly for his clients and makes himself available almost 24/7. He friendly and enthusiastic personality will make you feel like your are his only priority. Don't trust anyone else with your most important asset.

Let me start by saying that I have known Mike for over 20 yrs. Have bought and sold multiple homes with Mike's expertise. Every experience has been the most professional type of representation you can ask for from not only from Mike himself, but the entire staff at Golden Key. When selling, Mike spends the time and resources necessary to display your home properly for optimum return. As a buyer his yrs of experience and knowledge of the industry stand alone. Thank You Bob & Diletta Michael Santini
I couldn’t imagine buying our home without the help of David Santini. He is a wealth of knowledge regarding the home buying process as he has been in the business for many years. He was responsive to our questions and concerns and always has our best interest. If I had to do it all over again, I would still choose Dave.

David Santini
Mike and his team has helped me numerous times. First time was with the purchase of my house 28 years ago. (which I still reside in and love) He was patient, new the market, understood what I needed. He provided great advise and assistance from searching to closing. Mike then help us sell our starter condo. Most recently, he sold my mom's home for a great price and gave great advise in getting it ready for market. Won't use any other realtor. D.M. Convery                 Michael Santini
