The answer to Daney’s question is simple.
Yes, your house is tied to all those things.
But, for any given house, those things didn’t become significantly better between 2000 and 2005, yet prices skyrocketed.
So, when you ask “Have these been factored into the recent downward trend in the housing market” the answer is “no – they shouldn’t be” because we are in a speculative bubble and those things weren’t factored in to the massive price increases.
It’s kind of like the weather. Yes, the weather here is great, but it isn’t 3 times better than it was in 1998.
