Aurelius1, using selected periods such as 30-35 and 73-75, again is misusing stats given the structural changes that have occurred since then. As to 30-35, this seems to be depression years and totally undeveloped financial economy. As to 73-75, these were years when credit crunches occurred imposed by changes in govt policy.
However, had you bought a property in the highs before the 30-35 and 73-75 falls, you would be well a head today.
A1, I have a funny feeling that everything you are saying is academic, rather than practical, and you seem a bit Keen to provide a lot of professor type answers.
But again we are asking why you think that it will be a good time to buy in 9 months.
