Like, George, we used
Internet banking and signed up for auto pay on everything possible. We still had our home at the time, so a trusted friend handled our checking account, paying any bills that showed up.
We withdrew cash with our debit card in the local currency whenever needed through the ATMs that are everywhere in the
eastern Caribbean. Our credit cards charged a 3% foreign currency conversion fee, so we used cash whenever possible.
If you're planning on selling your house and will have no U.S. address, consider using a mail forwarding
service. Your address there is a "Personal Mail Box" (PMB) that will serve as a
legal address for financial services like your bank and credit card billing address. Go with e-billing to eliminate paper bills. We've been using St. Brendan's Isle, in Green Cove Springs, FL since we moved to
Nevis, and they are very accomodating of any special needs.
