Mia Kaiser is a Licensed Real Estate Salesperson with Signature Premier Properties in Smithtown. She lives in Smithtown, has been on Long Island for ten years, and works across Long Island, in Suffolk and Nassau, with Smithtown, Port Jefferson Station and Manorville as her home ground.

She handles a sale from pricing and preparation through negotiation, appraisal, title and the closing table, and she holds the SRES and SRS designations.

Outside the business she is a member of the Ronkonkoma Rotary Club and does dog rescue.

How Mia works a listing

  1. Price and prepare before anything goes live

    The number and the state of the house are settled first, together, so the listing goes out ready rather than being fixed in public.

  2. Stay on it through appraisal, title and closing

    Mia does not hand the file off once an offer is signed. The appraisal, the title work and the closing are where deals fall apart, and they are handled by the same person who priced the house.

  3. Deal with problems before they arrive

    Most of what goes wrong in a sale is visible early. Mia looks for it early and raises it early, so it is a conversation and not a crisis.

  4. One person you can actually reach

    You deal with Mia from the first call to the last signature, and she answers.

Working with Signature Premier Properties

Mia Kaiser operates under Signature Premier Properties, Licensed Real Estate Broker, at 7 West Main Street, Smithtown, NY 11787. The brokerage handles the compliance, escrow, and legal side, which is the part that should be boring and usually is.

I recently had the pleasure of working with Mia on the sale of my home in Massapequa. From start to finish, Mia gave 100 % of herself in making this very stressful transaction happen flawlessly!! Mia showed up every day armed with a huge smile and ambition to help me in every aspect of the sale. It's very rare that you meet someone who truly loves what they do. Her passion for real estate in beyond evident. Even with all the bumps we hit along the way, she handled everything with the utmost professionalism. I will be forever grateful that Mia held my hand in selling my childhood home. I'm fairly certain I was not the easiest client to work with, but she made me feel like all my craziness was warranted (God Bless her.)

I appreciate Mia's agility. She was able to change her plans quickly so I could get a private viewing before an open house. I was the first offer which was my goal. I think that was a key factor in getting an accepted offer so quickly, especially on long island. She is also fast with the paper work once you tell her what you want to do. As a first time home buyer it was an enormous help that she was able to work with my mortgage broker, lawyer and insurance agent so seemlessly

Selling a home can be one of the most emotional and stressful experiences, but having Mia Kaiser by my side made all the difference. Not only is she an incredible realtor, but she is also a genuine, caring person who truly puts her clients first. From the very beginning, she guided me through every step of the process with patience, professionalism, honesty, and constant support. Her knowledge of the market, attention to detail, and dedication helped sell my home quickly and smoothly, but what meant the most to me was how much she truly cared. I never felt like “just another client.” She always made herself available to answer questions, calm my worries, and make sure I felt confident throughout the entire journey. I am beyond grateful for everything she did for me and cannot recommend her enough to anyone looking to buy or sell a home. If you want someone who will work hard for you and genuinely care about your experience, Mia Kaiser is the one to call!

Mia Kaiser is one of those professionals people genuinely love working with. She’s attentive, reliable, and always puts her clients first. I consistently hear wonderful feedback about her and the experience she creates.

Kathleen Cella Google, April 2026

Mia made what was a very complicated and emotional situation, seamless and went above and beyond to ensure that my family was comfortable, well informed and part of every decision. I cannot say enough about the level of professionalism she carries herself with, as well as the time and dedication she put into the sale of our home. I would recommend Mia Kaiser and use her in the future for any realtor needs.

MIA!! Is truly the best! As a first time home buyer Mia made my fiancé and I feel less nervous and more comfortable with the home buying process. Mia went above and beyond for us and spent so many weekends and week nights trying to find our home! We will forever be thankful for Mia for making this time in our lives less stressful and we knew that we were in good hands!!

Alexa Inzalaco Google, August 2025

Thank you so much to Mia! Mia stood with us through countless weekends in a crazy market, and eventually closed our deal with ease handling both the title and the transaction. You won’t go wrong speaking with her if you are buying or selling!!

Michael Raimondo Google, August 2025

Mia is Amazing. She is patient, kind and understanding. Of all the challenges that moving can mean, after a very long history in a home it can be difficult. She respected our attachment to our home and understood what we were looking for in our next home. She listened to our needs and wants and made sure they were a priority in the property’s she showed us. At the end we found our dream home and sold our home to a family that felt the same way! Kissmit. Not only is Mia our forever realtor. She is now one of our most cherished friends. To many days on the beach. Thank you so much Mia!❤️

I am writing this review with sincere appreciation and gratitude for my realtor, Mia Kaiser. I am so thankful that Mia was recommended to me from multiple friends and acquaintances. I have been talking about selling for a while...it was time. However I was extremely nervous. I had a unique property in Smithown and I was looking to down size. After the first interaction with Mia I felt relieved. I knew that this was the right decision. From start to finish it was easy and exciting, even with the bumps that come with selling and buying at the same time. Mia was always available to answer all of my questions and concerns....there were many! She handled all the negotiations effectively and professionally as well as with honesty and integrity. I would recommend her to any of my friends and family with the utmost of confidence.

The thought of selling my parent’s house was one of the most stressful things I had to do after my mother’s death. Every time we thought we were almost there another issue would arise. Then my real estate ANGEL 😇 swooped in to save the day. Mia has been there since day one. She has helped navigate everything from setting a timeline, finding professionals to help with the plethora of issues that needed to be fixed, helping to organize and clean out the house, and being a sounding board for me when my sanity was in question. She is always kind, understanding and extremely helpful. It is true that God puts people in our lives when we need them most. My family will forever be grateful for her and all of the “extra TLC” she provided. Thank you! ❤️

Michelle Lawrence Google, November 2024

Mia made my home buying process so smooth and hassle free. From start to finish she was knowledgable, friendly and professional. I couldn’t thank her enough for all that she has done for myself and my family. We are so glad she was the one to help us through it all. I would recommend mia to anyone in the market for a home!

Samantha Gual Google, October 2024

Hands down!!!! From the very beginning to the very end, Mia has been amazing!!! She was professional, efficient, effective, proactive and super kind! The home purchase was basically flawless (unheard of, I know). I highly recommend Mia for any purchases or sales! You will not regret it!

Mia was a wonderful realtor! She went above and beyond in every sense of the word. Extremely professional, calm, nice and helpful. She was wonderful at hosting the open house and was there to pick up the phone and answer any questions any time I had them. She listed our house at the right price and succeeded in getting us a strong offer that was well over ask. She assisted in every step of the way to ensure a smooth closing. She made an extremely stressful process less stressful. I will definitely be recommending her to my friends and family.

Rachael Seigleman Google, September 2024

What can I say other than Mia is my best friend of 20 years and has been practicing real estate for at least 10 of those years. So when it came time when Mom lost her husband and was ready to move to Florida to be with her children there was no other person to help us but Mia. To say she knows her stuff is an understatement. She has helped us through this difficult time and now we are closing in a few weeks at our beautiful condo at Babcock Ranch. She didn't only help my mom with the selling of her house in New York but she helped me with my mortgage in Florida. I don't know how we would have done all of this without her.

A committed, knowledgeable, and motivated realtor, Mia Kaiser recently managed the sale of my father’s home. We reside out of state so were grateful to work with a capable and reliable agent. She did a lovely job staging, held open houses and managed the sale negotiations efficiently from start to finish. She has wonderful communication skills and follow-through which made our sale as stress free as possible. I highly recommend Mia!

Patricia Murphy Google, March 2024

Mia recently helped us purchase our second home in FL, she interviewed Florida agents for us, connected us with an amazing lender and was hands on throughout the process, explained everything so clearly in a way that made sense. Not having much familiarity with the real estate market, Mia answered all of my questions and was so responsive throughout the entire process. I would highly recommend Mia to anyone I know who is buying and/or selling. She’s the BEST!!

Summer Weiss Google, January 2024

Mia made the process of selling my deceased Aunt's home easy and flawless. As a first time home seller, I had no idea what was involved, but Mia's experience made the sale of this house seamless from start to finish. She explained everything clearly and was in constant communication with me throughout this entire ordeal. She told me in the beginning that we would become best friends over the upcoming weeks and she was right! I would highly recommend her to anyone looking for a real estate agent to buy or sell a home.

barbara roberto Google, May 2023

Mia has been such a wonderful agent. I am finally closing my first house with her and I am so thankful to her. She has been so patient with me, every step of my journey to finding a house in this crazy market. I must have seen over 30 houses with her. She is very knowledgeable, resourceful, and helpful. She went out of her way to help me any way she can. She accommodated my last min request to see houses. She treats her clients like family and gives her best possible advice. She is kind, friendly and very easy to talk to, that made home buying process a lot more comfortable for me. I appreciate all the newsletters and home guides that I received from her on monthly basis. I would definitely recommend her!

Jit Rye Google, April 2023

I would highly recommend Mia Kaiser for buying and selling your home. As a first time home buyer I was very nervous and not knowledgable of the process. Mia helped us every step of the way and made the process so easy and made me feel so comfortable. She is very prompt to reply to all my questions no matter the time of day. After just a few weeks she feels like a close friend and not just a real estate professional. -Cat Dennehy
