First thing to clarify on the condo question would be to get confirmation that Nepal's Parliament actually approved that plan, originally put forward in 2012, which would allow foreigners to own apartments in apartment buildings. I think you'd have to check on current status with a lawyer. What sticks in my mind, however, was the high price tag of those condos quoted in the press and elsewhere and, if my memory serves me right, there was like $250,000 minimum amount that foreigners would be asked to pay for their purchase...And that was 6 years ago! If I now seem vague on the subject, it is because this information seemed so outlandish to me back then, I never even considered the matter any further.
Besides, from my personal point of view, if I come to Nepal, it is not to live in a tower or high rise buildings but, rather, to enjoy the countryside and the beauty of the hills.
As a footnote, whenever I happened to drive past so many of those high rise apartment buildings past Patan in Saddhobatto area in 2015 after that terrible earthshaking quake, I could see the heavy damage and cracks all over those buildings. Many of those tall heavily damaged buildings were either completely recovered with heavy green tarpaulins, or under re-construction or plain closed, with no one living in them. At the time, I thought to myself, "NOT for me!" - but that is a personal opinion.
Other footnote in attempt to clarify: In Nepal, either a person has a Lal Purja Land or Property ownership certificate which insures that person to have Security of Tenure of a given property - or he/she doesn't -
Alternatively, someone who is renting or leasing a property under Contract has NO comparable security of tenure, be it on a short or long let or long lease or "for life".
