About Nina Mandeville

Nina meets her clients where they LIVE.....

Offering a focused, personalized service and tapping an established network of personal and professional contacts, Nina brings her depth of knowledge and expertise to her clientele.

Nina’s energy coupled with her professional approach and her ability to think beyond the straight line have repeatedly won her the confidence of buyers and sellers alike, most of whom are either repeat clients or referrals. Her listings include many which are unique and high-profile.

Active listening, in-depth research and an unwavering commitment to minding the details is greatly appreciated by her clients. Nina chooses to limit the number of buyers and sellers she works with at any given time in order to maximize her service to each client.

On a more practical note, Nina understands the importance of data and provides her clients with stats tailored to their market sector. Understanding past sales, current competition and market values are vital to making informed decisions for both buying and selling. As most real estate transactions are emotionally charged grounding decisions with data is critical.

Nina also believes in the importance of first impressions ! She takes time and works hard at preparing her properties to go to market. Staging, professional photographers, videographers, floor plans, custom brochures are standard to all of her listings and are essential in today's digital real estate market.
