John Tiburzi

Licensed Real Estate Salesperson at Signature Premier Properties

John Tiburzi, Licensed Real Estate Salesperson
  • 6 years selling on Long Island
  • 85 closed sales on this site
  • 41 towns with a closed sale

John Tiburzi leads Team Tiburzi Real Estate at Signature Premier Properties. He works across Long Island, in both Nassau and Suffolk, and has closed in forty one towns. Knowing which blocks flood, which districts move a price, and which buyers are actually approved is the part of this job that does not come out of a database.

He handles listings personally from the first walkthrough through the closing table. Photography, pricing, negotiation, and the calls nobody enjoys making are his, not an assistant's. Sellers get one point of contact who has seen the file since day one.

Outside the business he is a lifelong Long Islander, which means he has opinions about bagels, traffic on Sunrise Highway, and where the good beach parking is.

How John works a listing

  1. Walk the house before talking price

    Every price conversation starts after a walkthrough, not before. A number given over the phone is a guess, and guesses cost sellers money in both directions.

  2. Fix the paperwork first

    Certificates of occupancy, elevation certificates, tank sweeps, survey. The documents that kill deals at inspection get pulled before the listing goes live, not after an offer is on the table.

  3. One point of contact

    John takes the photos meeting, runs the open houses, and negotiates the offers. If you call about your house, you get the person who has seen the file since day one.

  4. Tell you the truth about the number

    If the house is worth less than you hoped, you hear it in the first meeting. That conversation is uncomfortable once. Sitting on the market for ninety days is uncomfortable every week.

What clients say about John

5.0 from 5 reviews on Google and 5.0 from 5 reviews on Zillow

We had such a great experience working with Team Tiburzi at Signature Premier Properties on the purchase of our rental property in Patchogue. From the very first showing, Johnny was able to offer valuable insight not only as an experienced realtor, but also as a rental property owner himself. His perspective helped us look at the home through both a buyer’s and an investor’s lens, which was incredibly helpful throughout the process. Brendan Dougherty, in particular, went above and beyond for us from start to finish. He was always available to take our calls, answer our questions, and help us navigate every step of the purchase. When we were held up waiting on survey paperwork from the Village, Brendan personally went to the town to track down the documents we needed so we could keep the closing moving forward. He even went to the property the morning of closing to make sure everything was completely broom swept and ready for us. That level of care and service is rare and we felt supported every step of the way. Talk about full service from the first showing all the way through closing.

Excellent help from start to finish throughout our homebuying process. John and his team took the time to learn exactly what we were looking for in our new home, find great fits, and provided advise and guidance at each step of the process.

Johnny helped my wife and ME (yes, the proper way to say that is me, not I) sell our first home and purchase our second. I knew Johnny had a good reputation, but what ensued was ridiculous. First, he came over with printed versions of all comparable homes that sold and were for sale in our area. He compared our house to those and explained why or why not certain things were they way that they were. For example, time on the market could mean that there was an inspection problem, as the listing said something about an older roof. You get the picture. He then asked us what WE thought we could sell our home for. We had a discussion instead of being spoken to. Then, this man turned over every stone and went down every rabbit hole to find us our dream house. Not only did we see so many houses that were perfect for us, he accompanied us personally to every single one, told us how much we should offer, followed up with every agent instantly and repeatedly, and kept in constant contact with us about what we should do. While we started doing this, his team took photos of our current house, plastered them all over social media, and actually used REAL PHOTOS! No ai! Imagine that! We sold our home very quickly and moved into what my wife calls "her barbie dream home." People always say buying and selling a house is a stressful experience. I truly don't know what they're talking about because of Johnny. If you want to sell your house for the best price possible and get into your "barbie dream home" don't mess around hiring someone who dabbles part time. Hire JOHN TIBURZI!!! AND ANNETTE!

John was my realtor when I purchased my home he made the process so smooth and easy. He is very educated and knowledgeable and answered all questions I had without hesitation. I highly recommend John and his team they where very professional, outstanding experience.

John is a phenomenal agent. He helped my husband both sell our previous home and purchase the home we are in currently. He was very thorough and answered all of the many questions I had about the process. He put me at ease (we all know moving is stressful!) and truly advocated for us to help secure our dream home. I cannot recommend him enough for anyone who wants a seamless and streamlined home sale or purchase process.

Working with John was an absolute pleasure. He made what can be an overwhelming buying experience feel easy and enjoyable. He was always friendly, honest, and straight to the point, which made us feel comfortable and confident throughout the entire process. From the moment we started looking at homes all the way through closing, John made everything as smooth and stress-free as possible. We couldn’t have asked for a better realtor and would highly recommend him to anyone looking to buy or even sell a home!
