My wife and I are about 12-17 years out from retirement. I receive a military pension and will receive social security. We have medical thru our retired military plan. We are strongly considering retiring to Spain. Financially, my pension is about 55k a year (gross). Coupled with SS this should go to about 80-90k. What things do I need to consider for our move? We have lived abroad before (Germany, Korea, and Jordan).
