H,
You don't have to be a resident to rent or sign a lease in Roatan or anywhere else in the country. With the lease it is your place so you can come and go as you please, anywhere you want and that would include out of the country. It is no different than in North America. When your 90 days are up you either apply for an extension or go on a vacation out of the country for a few days. If for some reason you will be out of the country at the end of the month when rent is due, either pay it in advance, get a trustworthy friend to pay for you or do a Paypal, bank transfer or wire transfer depending where you are and what you prefer. It is very easy.
