Me+4 best friends = 5 households:
=> we'll start to die after 10 years, whenever we all die, there are only 2 kids out of the 5 households. At least 3 extra bungalow/condo will be emptied, out of 5.
.
my children will buy your condo, because i will live for another 40 years, maybe more, and i plan to stay where i am.
