Hi Andy,
I know Ceara quite well, eu had property there for 2 years. going there again for the 6th time on Thursday for a month. Which town is this Coconut Grove development you are asking about? $23K seems alot to me for only 450M2 at 300M back. Sounds like the usual high price for the gringos! Beware!
Ceara towns are usually much more developed than RGDN areas so better infrastructure and so can make money quicker, also less risks as its big for the internal tourism and so has a much bigger market. Not too sure if Banana residence is a big success yet as its not built, and personnally I didnt like the plans of the construct.
regards
Paul
