Mary helped me and my husband with the purchase of our new home in Bellevue. She is very knowledgeable about the market. Her outstanding negotiation skills definitely helped us in acquiring our home which had multiple offers.

My wife and myself were new to home purchasing and like most new couples, we decided to go view “open houses”. Mary Nelson was the listing agent and right away started answering all of our typical 1st time buyer questions. We did our homework and Fast forward a couple of years (recession, kids, life), we decided to ask Mary to help us find a home.

We were mostly interested in the Eastside (Newcastle) but Mary seems to know every single inch of King County. I highly recommend Mary to anyone looking in any price range. She offers great communication, punctual, very knowledgeable and is just great to work with. She helped us purchase a home and we are now official “First time home buyers”

If you are looking for a hard working, thoughtful and successful agent who gets results then Mary is the person. She was on top of the process from beginning to end and we never had any surprises. Her approach gave us confidence and made this major event smooth. I can’t say enough good things about her investment of time and attention give to us.

We had an excellent experience working with Mary Nelson and her team in 2013 when we sold our house on Mercer Island. Very professional agent with lots of experience. Mary was our 2nd agent for the sale. We initially chose someone else, another very reputable agent for high end real estate, but were quickly dissapointed with the way they represented our interests. Very pushy and unprofessional. Invest as little as possible and sell for the least amount as quickly as possible was their attitude. We had a completely different experience with Mary and her team. Our interests were her main goal. Mary taking the time to understand how much our property was worth regardless of comps, ultimately made her the best agent for us and got us very close to the price we were looking for. We will definitely work with Mary again. Highly recommend her.

Mary helped my husband and I purchase a home in Bellevue, WA in early 2014. Our budget was on the low end of the market and her advice, support and diligence resulted in us finding a home that was much nicer than we anticipated being able to buy. Initially negotiations for the house began on Christmas Eve of 2013. Even during the busy holiday season Mary was incredibly responsive and focused on our home purchase. Mary calmly walked us through some emotional moments (when we thought we might not get the house because the seller was a little unreasonable) but she didn’t let the deal fall through. We recently referred a friend of ours to Mary. Our friends’ experience was just like ours: five stars all the way!

There is no other real estate agent that I have ever worked with that has the professionalism, ambition, expertise, communication skills, and follow up then Mary Nelson. She is am expert in the Seattle area market and I would not hesitate to hire her again! She helped me purchase a home when I was living on the East coast and made the transaction easy and smooth. She still continues to help me with various issues that arose after purchasing my home. She is a 5 star agent without a doubt!
If you are in need of a fantastic realtor ... Mary is your girl !! Smart ..honest and responsive to any questions and concerns. She helped us purchase our home with very little trouble and we will use her again in the very near future ... Highly recommend and 5 stars all the way!
In 2012, Mary Nelson became the greatest asset to my deal of a lifetime — the purchase of a dream home contingent upon vacating and selling three rental properties, requiring all four transactions to sync within a 3 to 4 month period. Many agents would not have attempted it but Mary believed in me and guided us through with excellence, efficiency, class and compassion, going above and beyond for my family. Anyone can learn the real estate trade but it takes an exceptional person to navigate the emotional component inevitable in buying, selling and moving. In the midst of it all, two tragedies struck our family. On the days when my will was broken, Mary stepped in at every turn, acting with me and even for me, connecting me with the many resources at her fingertips. As an added bonus we had the entire team at Brazen Sotheby’s offering fantastic support and collaboration. I can’t say enough about Mary Nelson. I recommend her without reservation.

Mary was professional, friendly, knowledgable and made you feel like you were her only client. She worked hard for us and was patient with us. She was also an excellent t negotiator! I recommended Mary to my parents who were moving from CA up to WA and she found them a home quickly! I will always recommend Mary to our family and friends and plan on using her for our next home purchase!
