Silver price 1973 $2.55, now $16.50, annual rate of return of 4.24%p.a.
Median Sydney house price 1973 $27,400, now $970,000 annual rate of return of $8.25%p.a.
That's excluding any rent. If we get an annual return of say 2.5% and compound it from 1973 that would give an annual return of 10.75% p.a. and probably a lot more because the rent's compounded.
