How Much Money
Hola Nickcr
great question and its good to see the many replies.
first being in Costa Rica you are already ahead of the curve since your money actually goes further ( depending on vices

)
I don't believe its safe to actually have large amounts of money in liquid investments since the near future I see alot of changes.
someone mentioned and I agree is not having large amounts of money BUT diverse income streams. and if you do have large amounts of cash available. I would purchase smaller tico style homes under $100,000 for cash and rent them. taxes are so low that most of the monthly would actually be profitable.
so you could own 20 small homes and you would have an income stream that will be consistent while still protecting your initial cash.
if you do NOT want to rent them then then next best thing is to become the bank and give 20 or 30 year mortgages at a good interest ( this is what I do since your better protected in case of default) in costa rica if you default you can foreclose in 4 months as opposed to kicking out a tenant that renting.
this is as secure as they come.
then mitigate your risks by adding different styles of online revenue
adsense
offline consulting
etc
and as you build your business you save a certain amount them buy another small home. I say smaller tico house because there is always a market for tico homes under $100 grand.
I know alot of guys buy precious metals which is good but I have not much experience in this
my longer term plan is to have NO DEBT which I do..

I owe NOTHING
and have rent able income that I get that I dont even declare and this monthly income pays the monthly bills as I build other streams of income.
at the moment offline consulting.
I also purchased a nice 2 acre compound that I am building a completely self sustainable home to provide for my family which includes or will include
solar and wind power
bio dome
aquaponics
etc
so i will always have food in the event something happens
all in all you made a great choice because
step 1
is get the hell out of the states before they don't allow you to leave
with the new trend that going up is
relenquishing U.S. Citizenship
as of now you can only take out of the country net income up to $600,000 all monies after that is taxed again I think at 15% although I am not sure.
so you will pay another 15% on already taxed income crazy
they just passed a new law that states
there is a $500 fee associated to giving up your citizenship LOL
pm me when you get a chance
