Investing in land is very good idea however if you look at the market  it looks bit sluggish at the moment but I am very much optimistic that the market will recover soon. Nepal is a developing country and I dont see gloomy future in land investment.

I think other rock solid investment is fix deposit. I would be better off if I would have done fix deposit the sum I invested in land last year. some banks are paying up to 4% APR if you deposit over $50,000 so I am thinking of bringing my money back.
