I would be happy to help you to sell your home in Mastic Beach. I live in the neighborhood :-)
Whichever Realtor you choose to work with, check to see how they will market your home: whether they will market locally only, or further afield. Personally, I was drawn to this area by both the natural beauty and affordable housing, both of which can be very appealing to buyers.
I wish you the very best with everything that is going on in your life right now!
