This is for Shajhakohero urf pinki, no doubt you are nepali ID holder (nagrikta wala) but dont think that its very hard to get it. I know a handful of Marwadi, who got nepali nagrkita not because of anything but coz of money. And you can get nepali id (nagrikta) if you have money.

Talking about the land or any other property in Nepal you can buy it with money, your nagrikta will not help you in any ways to buy it, even banks or financial institution doesnt give anything only with it.
