We have been living here part time since July 2004 and full time since May 2005. A few things about living on Bonaire.
1. You need to be flexible. Instant gratification on Bonaire is not possible. Also, don't make your "to do" list more than 3 or 4 items a day, and be really happy if you accomplish 2. You also have to be creative, sometimes the solution you need is not available, so you have to come up with an alternative solution (especially when it comes repairs!)
2. You need to understand and appreciate the culture. It is not "Americanized". For example, the locals consider it "rude" to say no. Example: If you are having work done on your home, don't ask the question, Will this be done by Wednesday? The answer will always be yes, with the hope they can get it down by Wednesday, but when Wednesday comes, it, in all likelihood will not be done. To get a more accurate reading on the situation, ask "What day with this be finished?".
4. I have to tell you I don't think, over all that it is more expensive to live here than the states. Food is more expensive, but health care and property taxes are much less. I can tell you that some things are MUCH less expensive if ordered from the US. Patio chairs I wanted for the Inn were 125,00 each (about $70 each) and I found them at Lowes On Line on sale for $18.74 each! Including shipping and duty, I saved $335.00. Also with the new infastructure setup, there will no longer be duty on items (with the exception of new cars - 25%), so prices will hopefully be much lower soon! On the other hand, I got my solid teak dining tables and chairs for about 1/3 less here on Bonaire, then I would have paid in the states!
5. Basic medical care is very good on Bonaire, and it is only going to get better, with the direct ties to Holland. They are big on preventive care and alternative medicince complimenting traditional medicine. I had a medical emergency last year, had medical care and surgery at a private hospital in Curacao and was VERY happy with the care, doctors, hospitals, everything. I didn't get a bill, or have to pay cent...it was all covered by insurance! Also FYI if you are over 60 and a retiree you have to obtain private insurance.
I think the factors you need to consider if you want to move here are these:
Do you want to live a laid back relaxed lifestyle, then when you get the urge for "concrete civilization", you are a flight away, and Bonaire could be a good option for you. RU ok with dealing with different cultures, languages and people?
If you are into shopping malls, bustling city life and instant gratification, well then Bonaire is not for you.
Hope this helps.
