Mark and Shelly from Realty One were great. They made my home selling experience so easy. From painting to staging.....they sold my house in no time!

I can't put into words how glad i am that my neighbor introduced me to Mark. My house had been on the market for 90 days w/o an offer.
After Mark took over the listing i had an offer within a couple of weeks and the closing process was so effortless that the whole thing closed in about 2 weeks.
My neighbors told me the difference between Mark and the previous RE person was like night and day. Mark did several open houses, had the house listed on a RE agents' caravan. He advised me on staging and had a photographer take incredible pics so that the house really showed at it's best.
Thanks Mark!!

After 21.5 years in the same little house, my wife and I decided to upgrade to a house that we can share and create many new lasting memories with family and friends. We reached out to Mark to help us with this journey. Mark assisted us with the selling of our current home as well as helped us find a home that met our very specific wants. This was not an easy task. Not only were we not up on the real estate process but we wanted a very specific house. Mark stepped up to the plate and hit a home run. Mark was not just a real estate agent. Mark was very patient in educating us on the ins and outs of the process, provided guidance (recommendations – choices were all ours), juggled both the selling and buying of the homes, shared contacts to complete needed tasks and truly had our family has the main focus of this transaction. Mark went above and beyond the call of duty as my wife and I have very tight schedules and we were trying fit this life changing event into a small window. Somehow, Mark made it all happen. If you are looking for more than a real estate agent, Mark Koumelis is the gentlemen you want to call.

Mark was so great beginning to end even after we funded he is still helping us and is willing to answer questions. He was able to schedule appointments and go to showing based on our personal schedules, he worked harder than the selling agent that's for sure! And he was very knowledgeable about different cities we were interested in looking in and gave recommendations of companies to use for home warranty, internet, etc...overall this was such a stress-free experience and I am glad my Mother recommended him to us, thanks so much Mark!

We were looking at a rental property that Mark was showing. We were told we were chosen and approved for the house. A few days later we were then told by Mark someone else was chosen because they make $12,000 per month. This seems pretty shady, and my husband and I make more than enough to pay the rent. What makes the way we were treated even worse, we’re supposed to move in two weeks and I’m 40 weeks pregnant, now we have to start the whole house hunting and application process again. Clearly money is more important than people or relationships to Mark. This is not someone I would choose to work with.
