Hi Tony

Have you thought of looking at Joao Pessoa for properties you get a lot more for your money and the beaches are the best in the area.
Joao Pessoa is about 1hr 20min from Natal or Recife airports.
The tourist trade is just starting here unlike Natal.
I am from the UK and live here in Joao Pessoa and know many of the pitfalls of buying in brasil so if I can help you in anyway don,t hesitate to contact me.
