I found it accidentally, and could not resist, I have to inform people. If this is still valid of course. This small islet is 0.14 acre (566m2), its maximum length/width is 45mX20m, and is separated by the main island of Roatan (Honduras) via a small channel. It costs only 84 000$ according to this site where they are selling it https://www.7thheavenproperties.com/real-estate/honduras-roatan/cay-for-sale-014/
I am not responsible for any data or information. I gathered it from this link, I saw it accidentally. It could be sold already. Check yourself who is interested!
