pire,
Is it easy to convert the money from the sale to $$$ in Nepal and bring it to the USA? I don't think so.
If you are talking about keeping your investment and profit in Nepal forever or so, I think real estate is still a very good bet. Bank accounts are very volatile in Nepal, especially when there is no government at all. For that matter, every thing in Nepal is unstable.
If you are planning to do tele-investing from the USA, just forget about Nepal and have a wait and see plan in effect.
