Nonnie Dinges

A Trusted Name in Peninsula Real Estate since 1984

Client Testimonials

“After speaking to the candidates over a two-day period, we selected Nonnie Dinges with McGuire Real Estate. Why? Well, let’s face it, an hour of face-to-face discussion doesn’t always tell the whole story, but in this case we got a strong sense of energy and experience from Nonnie that we didn’t get from any other Realtor. So we signed with her hoping our hunch was correct. Frankly, when you consider everything that had to be done WHILE I was in Maryland, I am very satisfied with our choice. Nonnie performed her duties flawlessly and made the process flow seamlessly. I couldn’t imagine selling a property long distance going so easy. The secret was having an agent that communicated effectively, knew her market, and worked with my interests at heart. I trust her commitment to do the right thing and would recommend her without hesitation!”

J. Hawkins, Maryland

“If I had to describe Nonnie Dinges in one word it would be savvy! She is a very savvy seller’s agent and a buyer’s agent and will also give 110% of herself to either. I’ve seen her work at all hours of the day and night to accommodate her clients and sometimes even other agents’ clients to get the deal done. She knows the Peninsula like the back of her hand, since she is a lifelong San Mateo native. Honesty is another strong trait Nonnie has. She doesn’t want to “just” sell your house or sell you a house; she wants to get to know you, build a relationship and represents your interests in the deal. She is down to earth and just a real person! I promise if you work with Nonnie it will be a positive experience and you WILL come back to her when you are ready for another transaction!”

T. Butera, Redwood Shores

“Nonnie is a skilled real estate professional with impressive wisdom of the Peninsula housing market. I used her to purchase my home 20 years ago in San Mateo when we decided to move from San Francisco. Her knowledge of all the various neighborhoods and schools was very impressive. It was her relationship and reputation among the local real estate agents that allowed us to purchase the beautiful Spanish home where we now reside on 25th Avenue. Recently she helped with selling my parents’ home which aided us tremendously by settling the estate within a matter of months. My mother passed late November, 2015. It was Nonnie’s careful evaluation of trending market activity that expedited our efforts to prepare the house for listing as quickly as possible. She had been watching the peak “above offer” homes sell and noted the slow down before others in her field were aware. She helped us every step of the way and spent considerable time educating my siblings who live out of the area. We were able to list the home and sell above ask in two weeks last March, 2016, while others on the same block remained for sale considerably longer. I have recommended Nonnie to friends and neighbors and would certainly use her again for any of my real estate needs.”

Gina DeCarlo, San Mateo

“Nonnie Dinges is a star! She found us our home in 2003 and now she has helped find us a new family to join the Otay community. We love Nonnie, folks. If you are looking for a home or selling a home, she is the only person to call in San Mateo. She knows everyone and everything that you will need to guide you. She is professional, generous with her time and a wonderful person all around. We highly recommend Nonnie!”

Erin Scholnick-Lee

“Nonnie’s attention to detail, as well as her award-winning personality has made her a complete joy to work with; Nonnie will always be the first name that comes to mind whenever I think of Real Estate!”

Shannon Wells

“Nonnie helped my elderly mom find a condo that was perfect for her. She knew exactly what would work best for an elderly person – no stairs and close to transportation. When mom passed away, we used Nonnie to sell the condo and she got us a great price.”

“Nonnie’s knowledge (and the fact she was born and raised in San Mateo County) of the area is so beneficial to her clients. There is no hidden agenda, just the true facts with Nonnie. She is most definitely extremely well-qualified and capable.”
