Moh,
I cannot agree on your premise of artificial and natural components. Real estate is a commodity like any other; it is simply less liquid than say a bond future.
I do not know how old you are but I do remember when mortgage rates (29 year terms back then with almost no exotic products) were below 5%. In 1955 my Dad bought his first house for $19,800 with a 4% VA mortgage (about market back then). Borrowed $1000 from my Mom's Aunt for the down payment. When I bought my first house in the early 70's the rate was 7.9.
We are still not there yet.
But investors always ultimately react to economic realities, en masse. When they have massive disposable income they will do things like buy second homes. When the stock markets dump they look for alternatives. We saw that clearly over the past 5 years in the runup of 2-4 unit properties.
I see nothing that is artificial or unnatural about that.
While what we say here will not amount to a hill of beans as regards market perceptions by participants, it still reminds me of a self-fulfilling prophecy. It is a little bit like me asking where is the stampede, where is the stampede? And then, not seeing one, I start shooting my revolver over and over again until the herd hears it and thinks, maybe I am supposed to run. And so they do; hence the stampede.
...RE value is created by 4 factors - scarcity, purchasing power, utility and demand. Demand is still high, utility has not really changed much, land is still becoming less available. What you are suggesting is that the purchasing power decline due to higher rates will impact everything else. I do not see that.
I see increasing population- CA is still projecting a 40% increae by 2020; many other states are as well. Demand WILL increase. Supply WILL decrease. So, the net impact of lower purchasing power, while it will mitigate price increases as it should, and perhaps even cause declines for a while, it is still only 1 part of the puzzle.
