Living in Jamaica full time takes commitment. During the years I lived "six months there and six months here", I realized I wasn't ready to commit. You can always find a good reason not to do something and that is why I never bought a house there.
From reading your previous posts, I take it that you feel everything will be stabilized in a year or so and then you will want to return. Seems a shame that you had not waited until then to buy your house and finally commit.
