The naivety of statements like "I wish it would crash" and "It's the lack of lending" are utterly astounding.
Profligate lending led to the situation we are now in, boom and bust alike.
Yes, there probably will be a housing crash at some point and I hope that none of you currently wishing for one are new owners when it does happen. You will not believe the anguish it will cause.
In the 80s we were fortunate, we had a small mortgage on a small flat. Many of our friends, also in their 20s, took advantage of the relaxed lending laws and bought family homes, had kids, thought they were set. Then rates skyrocketed, reached 18% and worlds came to an end, keys were handed in, people walked away from their homes carrying kids and huge personal debts.
They weren't stupid or greedy people either. They were just ordinary people who had been sold the dream of being home owners. Bear in mind that this wasn't the norm in the 80s. Most WC/MC people rented. They were they first generation to be sold that dream... the dream that still seems to override common sense, in individuals and governments alike.
So no. Much as it pains some not to own their own home, I can remember how much more pain is caused by losing one. Don't hope for a crash.
