Amazing bro...... Nice dream... but I got some reservation....

200 sq meter land plot costs about Rs 10 million anywhere in Kathmandu....... I guess you know this fact
Building a house as shown would cost about Rs 5 millions.....
Maintaining a house like that would cost about Rs 10,000  every month

The total cost of having such house and maintaining it for 5 years would cost Rs 16 million.... nearly equivalent to $ 200 thousands or 150 thousand Euros... ... and just think how long you have to work before you can save that amount......

For these reasons I suggest you to drop the idea.

But if you go to Nepal and start doing land business...
It will take you three years to earn that amount ....
And you can have such house.. plus beautiful wife
and ... many house like that... and many beautiful wives too if you want....
