Rosanne D'Agostino

Associate Real Estate Broker

As an agent who's an expert in this local area, I bring a wealth of knowledge and expertise about buying and selling real estate here. It's not the same everywhere, so you need someone you can trust for up-to-date information. I am eager to serve you. Here are some of the things I can do for you:

Find Your Next Home
You need someone who knows this area inside and out! I can work with you to find the right home at the right price for you, including all the neighborhood amenities that matter - not to mention the essential criteria you have for your ideal home

Sell a Home
When it's time to move, you need someone who will advertise your home, show to prospective buyers, negotiate the purchase contract, arrange financing, oversee the inspections, handle all necessary paperwork and supervise the closing. I can take care of everything you need, from start to close.

Consult on Home Selling Tactics
Oftentimes buyers don't visualize living in your home the way you do. I can make your home attractive to its ideal audience - which can help you get top dollar. Things like staging the home, making repairs or minor improvements, or even simply painting the walls can be the difference between a home resting on the market and one that's sold fast.


"Rosanne helped us with the sale of our home. She is a true professional in every sense of the word. I could tell she loves what she does by the way she represented herself and the many ways in which she advertised our home. She was a pleasure to work with. She prepared us for the process and made us feel at ease. She kept us well informed during the process and made the process itself easy and accommodating to us. She is very responsive, punctual, and on top of everything. I could not be happier with the decision to hire her. As a result our house is under contract."

"Rosanne D’Agostino is an amazing realtor who genuinely cares about her clients. On day one, Rosanne came well prepared with details about how we were going to proceed with the sale of our home. She lead us step by step through the process and hurdles we needed to overcome through the selling process. Selling a home can be stressful and worrisome, but not when Rosanne is by your side. Her time, knowledge, patience and expertise is second to none! My wife and I highly recommend her."

"Roseanne is a fantastic real estate agent! She was with us every step of the way in both buying our new house and selling our old one. VERY responsive and always up for answering our questions, no matter how small. If a potential issue arose, she was knowledgeable, and very quick with suggestions on how to resolve it. Our house is selling for WELL OVER asking price, and we could not be happier with Roseanne! HIGHLY recommend!"

  -JYule, Client

"...We got sound advice for upgrades and when we had trouble securing people/folks not showing up for jobs she not only helped us get reliable people but also never pushed us to list quicker than we were ready. We absolutely love our house and she knows it..."
