I am not an expert on this,but I believe it is too late to invest in land/house in Nepal.If you compare price of house in Nepal and USA,it is now cheaper in USA.And comparing facilities and earning,would you think it is worthy to invest in Nepal? I don't think so. Sooner or later Nepal will face huge financial and banking crisis and mimic US morgage mess.I wish I could be wrong..

Please do not let your emotion lead your financial decision.

Just my two cents.
