Hmm, I'm a big fan of South America and Mexico despite some political issues. Let's see how Brazil is doing politically over the next 5 years.
I always wanted to purchase property in Brazil, such as Sao Paulo and the Rio De Janeiro. Market to upper class and wealthy customers looking for tropical properties. My idea has always been to purchase acreage beach-front and otherwise, and market 50% to upperclass to wealthy foreign prospects (American, African, Asian, European, Australian, other)...and 50% to Brazialian locals.
Seems many homes in Sao Paulo are selling like upper middleclass homes in the American Midwest from prices between $150 to $500,000. Buy some homes available in specific areas....buy out a few neighbors and additional land property if possible....endure the costs of minimal to extensive renovation....and sell for at least 2x's the cost to e.g. American's who are in need of new vacation property. That is....one would have to research the socio-political environment and how accepting Brazil is of foreign RE investors.
