Sharon Costabile, MBA


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. In addition, with over 35 years of business experience, I am able to provide a tremendous amount of analytical insight to help you make educated decisions about the biggest investment in your life, buying or selling your home.

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 quickly.
