In my opinion, island property will always be a good investment, because there is only so much island. It can't grow--unless we had a volcano ;-D And we don't. People will always be attracted to live on or near water, and find the beauty of island living desirable.
I have lived on North Padre Island for 25 years and counting. I love it and feel blessed to be surrounded by so much beauty, good neighbors, safe neighborhood.
If you want a positive experience in finding an island townhome, let me help you.
