The OP asked for projections for 5/10/20 years. That is most difficult, particularly in the current global economic environment. In the ten years that I have observed the DR developments start and stop when the initial investment is exhausted. As with any investment, some work well while others fail. In those ten years I have visited Barahona a few times and have found that it is no where near 'tourist-ready'. It is a laid back, lovely Dominican town. However, 5 years, problematic; perhaps 10-20 with focus and good marketing. I would think that it really depends on your objectives. If you are looking for a nice place to retire, and you are willing to invest time in what some DR1ers have described as 'becomming Dominican', Barahona is a place to consider. If you are looking for an investment opportunity, unless you are in it for the long haul, be cautious and prudent.
