I assume you mean a beach house for vacation? If so, there's TONS of places out there. Just go to Google type in a more specific location like Destin beach house. There should be plenty of results.
I'm actually doing some SEO work for a house on Rosemary Beach (a new ritzy community like Seaside between Panama City and Destin.) If you're interested let me know and I'll give you the URL to the site.
