You misread me. I did not suggest that prices will not increase. I said that they probably won't continue to rise at the same rate as they have in the recent boom (plotted on a log chart). There is a big difference between the two statements and it is important.It is possible property prices will never rise higher than they are now, as suggested in this thread it is also possible a meteor will wipe us all out.
While a modest annual ticket price rise may be acceptable on property which was CF+ve at purchase, it is not good enough if net rent only meets half your interest bill. This boom in house prices (ex Sydney) has seen PEs increase from 12 to 40. For the same cap gains in the coming decade, rents will need to triple or investors will have to accept PEs of >100 or a combination of both. This is not impossible though. Hyper-inflation will mean that people will be swapping depreciating dollars for anything which holds value. But SSers, as a group, do not see hyper-inflation as likely and while I think it's possible there are other strategies I use to cover that possibility.
