So if you sold a rental and got 800k NZD you could buy a share of BRK.A.
That share would give you (roughly) $260 dollars a day in REAL income after all expenses. Or nearly 100k/pa.
in 10 years time, that same share will likely be giving you $700 a day or 250k per year.
I doubt that an average house will fetch $9600 in rent a week in 10 years time.
If a loaf of bread inflates at the same rate as historically, this could buy you 46,296 loaves of bread a year while keeping capital intact.
