We alway have ours paid through the attorney that handles the purchase for us...they handle the paperwork and make the payment, we pay them a nominal fee. It's much sompler than trying to figure it out and physically have to be there (although I wish I was!)
Are you paying taxes on caye Caulker??? What type of property?? We have 1/4 acre with 2 units and pay about $100 US a year...would be silly to pay a fee for such low taxes...you can pay 2 ..3 years in adavnce..but not sure what your situation is....seems some of these posters are from San Pedro which is a very different world.
For everybody's information, I use belizegial to do many functions for me, being an owner of property there and a non-resident, and she is the most prompt and efficient person you could hope for. I highly recommend her.
