  • Mariel listed and sold my home

      Mariel and team were excellent. Worked with us to find a home we loved and guided us seamlessly through the home selling experience. Felt they were honest with describing the market and finding a great price for our purchase and sale.

    • We first contacted Mariel in February of 2018 because we were looking for a realtor to assist my elderly parents with downsizing from their long time home to something that would be much easier to maintain and enjoy at this stage of their lives. Mariel quickly gained their trust and provided us with a wealth of information that assisted us with selecting a new place to live and also in helping us to dispense of furniture and personal items that would not be coming to the new residence. The house went on the market on May 23rd and closed on June 29th. I think that speaks volumes about her ability to get results. But what I really want to highlight is how adept she was at navigating the entire family through a very emotional process. Mariel provided the perfect balance of empathy and professional judgement of the marketplace. If you want a skilled professional and someone who really cares about her clients, hire Mariel!

    • We first contacted Mariel in November of 2016 as we were trying to understand what we needed to do in order to get our house ready for selling. Mariel came to our home, took the time to talk and walk our property and provided us with a list of items that needed to be addressed in addition to references of various businesses that could be of use to us for our particular needs. It took us a while to get our house "show ready". Mariel was not pushy during that entire time but rather remained patient and kept tabs on us every now and again offering assistance in whatever area we might need. Fast forward to May 2018, we finally were ready and reached out to Mariel to list our home. The house sold in one day! I echo a previous reviewer in saying I think that speaks volumes about her ability to get results, and agree that Mariel provides a perfect balance of empathy and professionalism. We could not be more happy with our selling experience and owe it all to Mariel!

    • Mariel and her team were excellent and went above and beyond to make our out of state move seamless. Our house sold over the list price in only a few days. Top notch professionals!

    • Mariel was recommended to us because we were originally interested in buying a lot and building a home on it. She initially came to our house VERY prepared to walk us through the process and answer all of our questions, as she has years of experience in new construction. After doing all of our research and planning we were ready to make an offer on the land.. Turns out someone bought it out from under us in cash. We were very disappointed but Mariel worked tirelessly with us in finding an alternative. After viewing countless lots and existing homes, Mariel really helped us not only by spending hours and hours searching for us, showing us properties, answering ALL of our questions, but also helping us understand what we really wanted for our forever home. At the end of the day we bought a house that we are absolutely in love with!Mariel also helped us with the sale of our house. From start to finish, every step of the way.. she was there. Mariel and her team worked with our mortgage broker, township authorities, contractors, inspectors, and everyone that needed to be involved. She made it easy to say the least. Saying the we would absolutely recommend her and her team to anyone interested in buying or selling would be an understatement. Her expertise is unmatched, we truly could not have asked for a better agent.
