Charleston Real Estate Advice





I work exclusively with the residential real estate market here in the Charleston area.


Mark Costello, Charleston full time Realtor offering expert advice. As a full time Realtor, I offer my clients over nineteen years of investment and real estate experience. 


I have represented some of the most influential and powerful people in the world and would like the opportunity to represent you. 

The Charleston Real Estate Market is very competitive and often times will involve very complex real estate transactions. As your Buyer's Agent, I will become your main point of contact and will oversee and manage your home's purchase from start to finish. Please remember the listing agent represents the seller's best interest not yours.

The Charleston area truly does offer the lifestyle and atmosphere only the luxury home buyer can enjoy such as beautiful salt water marshes, tidal creeks, and Atlantic Ocean beaches.  Together we will evaluate and determine your best choices in the price range you select.  The Charleston area is truly unique for the luxury home-class with its Atlantic Ocean breezes, Southern elegance, and rich history.  In my opinion, East of the Cooper, Historic Charleston and its surrounding areas will be a great place to call home and it really is living at its finest.

I look forward to the opportunity of showing you around the Charleston area and helping you identify your next home.  I know you will be pleased with your decision not only to work with me as your Buyer's Agent, but also in your decision to make the Charleston area your next place to call home.  Please feel free to contact me with any of your questions.
