The problem with steel is it "WILL" rust, dont care what yo do it will.
I to have giving some thought to this,
but the rust thing is keeping me from going forward with
it just yet. If you can buy a "new" container it would last longer.
Figure out how to seal the outside from water it could last many years,
longer than we will live.
Take this in steps
1)Find land in the place of the country you want
2) Check local codes, In TN you can wire 1 house a year with out an Electrial licences. (you do have to have a permit) most are good for 6 months.
3) Secure the land (buy out right or loan)
4) Put up a small place, ie Lowes building
Depending on how far of the road you build you may have to pay for the service to be run to
you pole. You will have to pay from the weather head to the inside of the house, and the pole
if you do it like a trailer service.
Now start on the shipping contaner house, concret pad, sloped away from
the center in all directions,(yea it will rock, use hard wood wedges that you can replace,
no where for water to pool, the rust thing again.
Dont bury them, dirt will keep water on the steel, rust thing again.
Find the land first, then move to the next step.
