I don't think your argument holds.Sure, there is an issue of demand increasing and supply decreasing, but that has been case since last fifteen years, and the house price has increased twenty fold in the last three years. Furthermore, land price increased across the country. I mean what explains increases in Janakpur or Butwal? They didn't attract immigrants running from Maoists or Madhesi movement. I think it is still the bank/dalal.

Also, I tend to think that if the land price doesn't increase in five years, it is almost like saying it decreased. Remember that you can get 12 percent interest at bank. So, in five years, you will be getting almost 80 percent of your money (byajko syaj pani hisab garda). So, even when the price is constant, it is like decreasing. Wise men should therefore just sell and buy back after five years. I wish I had understood it last year, and I wish I had realised that price won't go up forever earlier..
