Hi;
My name is Larry Schlesser and I own & operate RE/MAX here on Roatan. Before actually working you would need to have a legal residency. That would be your first step in the process. If you wish I can suggest a quality Residency Attorney. We are always looking for quality RE Agents with my company.
In regard to the cost of living I have a Cost of Living comparisons of many products and services. It is about 5 months old now but would provide a good overall document for comparative purposes. If you wish a copy send me an email to larry@roatan-realtor.com
