Land, Bulding and Gold are the most valued long-term assets in Nepal. If I had 200k money that I could invest in (specifically in Nepal), I'd definitely invest it in either of those three - the former two would get my priority even more because the market has almost reached its low.

But the question is, why are you wanting to sell your house? 5 years from now, there's no way you could imagine to buy the same land/building for 3 times as much, especially in Kathmandu.
