Your personal rent example: 650 -> 925 in 20 years is very meager growth, well below inflation: 1.78% per year.

So yes, less than 4%. A lot less.

>>> (925/650.0) (1.0/20)

1.0177975914387338

Note that 20 years of +1.78% per year does +42% compounded.

>>> 1.0178 20 1.4231442772353857

In real money, the rent for your place has gone down, not up, ignoring the furnishing.
