I thought a fold increase went, say
100 folds to 200
200 folds to 400
400 folds to 800
800 folds to 1600
?
otherwise it's a very hard way of saying it went up 4 times in value
A 4 fold price rampage - what period did that occur over?
also could you really buy a great house 8kms from Bris for $80k in 1999? I am just thinkign that there is no way a $500k Perth house now sold for $80k in 1999.
