"Some combination thereof"
Plan to sell the house for the bulk of my initial contribution, plus do some online work when we are in port.
My man will have a small pension plus some savings, he plans to do mechanical/fixit type work when it's available.
The work will be helpful, but not necessary as I am planning our budget
to be lower than our available contributions. If something really expensive happens then will work harder at getting some income
When I hit 60 and can access retirement
accounts penalty free then we'll switch over to that.
