I am passionate about real estate! I have been in customer service my entire career, and am determined to exceed your expectations. Always accessible; I enjoy educating & counseling clients; guiding them through the process and expertly negotiating on their behalf. On the emotional level; I love the smile on their faces as they find their perfect home, or find the right buyer that will love their home as much as they do....On the business side; I enjoy negotiating to get them the price and terms that are favorable to them. My background in interior design helps so that I can provide staging for sellers if they need it, as well as to help buyers be able to envision the possibilities of a house where there doesn't appear to be much. I will assist you in assessing your goals/objectives to your level of comfort; not mine. It is a process that is different for everyone. I believe that a good agent should listen & understand what their clients needs are, and to help them to attain them. I take that responsibility very seriously. I gladly provide references upon request. Please call me with your real estate needs; you'll be glad that you did.

Sold a Single Family home in 2017 in Huntington, NY.

We worked with Katharine Aguilar for over a year as she expertly guided us through the sale of our previous house and into the purchase of our new home. Katharine is professional, poised, well spoken, experienced, knowledgeable, and dedicated!! She anticipated our needs and answered all of our  questions in a calm, easy-to-understand manner. She is an efficient negotiator. Katharine is warm, and genuinely appreciative of your business patronage. She maintains a network of professional colleagues who she was able to recommend when needed. Two of our previous neighbors sold their homes at same time with a different realtor; both homes remained on the market, underwent price reductions, and sold for less than the asking price. Conversely, with Katharine’s assistance, we received multiple offers within one week of our open house. I cannot say enough good things about Katharine and our experience in working with her. I highly recommend Katharine Aguilar as your realtor!

My husband and I worked with Katharine to find the perfect home for us and for our budget. Katharine diligently searched for the best house to meet our needs- this process took over 6 months. We saw over 70 homes! Not all agents would be that patient and persistent. Katharine never pushed us to a  house that didn't meet all of our criteria. She even urged us to stay on course and keep faith that the right house was out there. I would highly recommend Katharine to anyone looking for a home on Long Island. She is beyond knowledgeable about the housing market in NY and truly cares for her clients.Thank you Katharine!

Katharine is very professional and knowable whose effort goes above and beyond. Our experience with her was stress free. I would highly recommend her to my friends and family.


I have bought and sold many properties but Katharine is the most knowledgeable and professional realtor that I have ever worked with. She loves her job and cares about people. If you are in the market to purchase or sell, Katharine is the person who you would want to help you.

Kathy was very helpful in helping me find my first home. She knew the area I was looking into and was able to give me the pros and cons of homes in the area. I never felt pressured for a second. As a matter of fact she was the one telling me to slow down a little and not rush. I felt her  expertise in negotiations were very helpful. I am very thankful for her help and landing me into my home. Kathy even still keeps in touch to check on how things are going.

Katharine walked me through the entire purchase process and is very patient and knowledgeable. Buying a home is a stressful process - at least it was for me - and Katharine helped me through it immensely.

Kathy is wonderful! She is professional and listened to my needs during the home search process. She is prompt is answering all emails and phone calls. She found my new home and my family and I couldn't be happier! I would highly recommend Kathy to anyone who is either selling or buying a home.

Katharine put a great deal of time helping me to find a tenant for my older ,somewhat tired house. She was able to suggest local painters, plumbers and floor people all of whom were very good workman.

Katharine was the finest Realtor my husband and I have worked with in the almost 2 yrs it has taken for my husband and I to sell our home and downsize to a different location. Her patience and Professionalism was outstanding! We most definitely recommend her as an outstanding Real Estate Professional

There were many times throughout our home purchase where Katherine's expirience and attention to detail kept the deal from falling through. It was a difficult and never ending ordeal with a happy ending that we were sure wasn't ever going to work out. My wife and our newborn got into the house and  couldn't be happier. Looking back through the way she negotiated and carresssed the deal we couldn't have expected anything more from anyone. She knew the area and recommended great local people to deal with the home inspection and building department. We had everything we wanted at the closing and she was spot on with her assessment of how it would go and the costs/taxes. She truly treated us like family and you can't ask for more. Than that. Two big thumbs up!

I truly can not say enough about Kathy. Besides being an incredible knowledgeable agent, she was simply a pleasure to work with during a very complicated and exhausting search period. My husband and I were looking for over 3 years and Kathy was such an asset. We eventually closed on a extremely  complex deal with multiple layers that required capabilities only Kathy could bring to the table. Its rare to find an agent that is the trifecta-- experienced/knowledgeable, savvy and a wonderful calming personality. Buying our home was stressful and certainly no easy task. We are grateful that Kathy was highly recommended to us and I'm happy and eager to refer her to my entire network.

There are not enough positive and appreciate words in the English Dictionary for us to truly describe our level of thanks and gratitude for Katharine's help in finding us our dream home! Kathy is a true professional who we met by chance after an unsatisfying, lackluster experience with a prior real  estate specialist. We truly lucked out with Katharine who showed us over 60 homes, always with a smile, and also with helpful advice and honest feedback. Kathy made sense of our likes/dislikes and actually helped us hone into what it was that we were looking for in a home because we truly did not even know ourselves. She truly goes above and beyond for her clients, has extensive knowledge about all things home-related, and has lots of excellent contacts to refer her clients to in order to help get the job done the right way and quickly. Although we are thrilled to have found our dream home, we will definitely truly miss Kathy!

We tried Kathy since she was related to a friend, but once we came to know her-we stayed with her and did not consider even trying anyone else. We were first time home buyers and wanted someone with integrity, honesty and knowledge-and also someone who would educate us and show us things that could  be very important later on. It took us a good 6 months to find a house-and that too one that she short-listed for us. She was a great help through the whole process and earns our highest recommendations..!!! In the crowded real-estate agents market, she indeed is someone who is professional yet very personal in her approach. An absolute delight to know and work with!!

Kathy helped sell our home in one day! She scheduled an open house on a Sunday and we had our offer on Monday. Finding and purchasing our "down sizing" new home was not as easy. Though the entire emotional process, Kathy was a true professional. My wife and I would Highly recommend Kathy's services.

Katharine is a solid professional that understands budget, location, value and does it with respect. I would use her talents in buying and selling a home with her. She has sold two of my homes over the years and helped us purchase two homes to boot! Excellent experience.

I have had the pleasure to work with Katharine for the purchase of my first home, which my husband and I loved, but after having a child and planning for a larger family we decided to sell and upgrade. The transaction for our first purchase was a little difficult, but Kathy managed to pull it  together successfully, we were so pleased that would not have anyone else sell our home and help us "find and buy" a new one. Kathy is extremely professional, she never left us wondering about what the next step was, her advise was honest and accurate. She is an strong negotiator and got us over asking price on the sale of our home and a great price on our new purchase. I gave Kathy a very specific list of what I expected for my new home, believe it or not, I did not think I would find it in our price range, but she did. She was Always focused in the main goal, which is a good thing as the process can be an emotional roller coaster. Just enterview her, she will have you at hello.

We still remember very fondly how she accepted the assignment of selling our house in time for the birth of our granddaughter with great energy and enthusiasm. She did not give up, even though the housing market was probably at one of its all time low points. She fought for us to get a fair price  even though she was pitched against an opponent who fought very hard for her clients, as if they were her own children. She was positive and focused throughout the 3 months that we searched for a buyer and all we can say is BRAVO! She took the challenge and delivered a successful sale of our home of 37 years.
