It sounds as though you have a beautiful home in a well-desired part of town. Your upgrades are also things that many people are looking for in this marketplace. I have shown many homes in this area and actually live around the corner in Waxhaw.
Are you looking to sell your home or do you just want to know the value. One way to get an idea of value is to hire a real estate appraiser who will come to your home to do the evaluation and compare the home to similar homes that have sold in the past few months. The second way is to have a Realtor pull a Comparative Market Analysis for you from the MLS.
If you would like more information about this, I would be honored to assist you. Feel free to email me at email@example.com where we can talk further about your needs and plans. Hope you are having a great weekend.
In the past I have had an evening open house and invited an artist or art gallery to come to display their art. I also asked them to give me their client list and I sent out invitations to their clients as well as my own. I also sent out invites to all of the real estate agents in the area.
