Congrats Sandytoes...there's some good information about moving to Negril in these threads...

For long term rentals...it's often easier to do the leg work while you're in Negril...it gives you a much better idea of the yard/owner/home etc.
We can suggest a few places...it would help to have an idea of your budget.
