Here's the best way I can break down the situation about the housing
bubble (or any other asset bubble in general):
1) Are we in a bubble?
There are a couple of ways to look at this:
a) Historical
Look at the history of real estate bubbles and see if you see
any common trends (the Florida Real Estate Craze being a common
example). See why those people lost big money and see if those
same situations are being set up again. If you want to see some
real craziness, look at the S&L scandals in the 80's and see
what that did to housing prices (as well as the housing
construction industry) in Texas.
b) Technical
Use any traditional measure for real estate investing. Are those
measure out of line with historical averages? Look at average
monthly payments, renting cost vs. owning cost history, interest
rates, maximum mortagages allowed, etc. A lot of those measures
are significantly out of line.
2) If this is a bubble, why hasn't it popped yet?
Okay, we just lived through a stock market bubble. Can you explain why
it popped? Even looking backwards, can you explain how and why it
happened? I certainly can't. I can say something like "All these
dotcoms aren't making money, so they'll go under when they run out of
cash". But I certainly couldn't predict when they would be unable
to issue stock or take venture capital (i.e. when they could no longer
get "free" money to continue operations).
Even some of the brightest brains applying complicated mathematical models
can't detect a bubble with absolute certainty.

Look at any graph from any bubble period (dotcom bubble, Japan Nikkei
index, RCA stock in 1929). Now, use a piece of paper to cover up the
graph before the peak. Move that piece of paper left and right.
Can you tell when the peak will occur?
2) Let's assume we're in a bubble, what should I do?
Unlike stocks and tulips, housing cannot be sold easily for a quick
profit (once you take into account the lender/seller/mortgage fees).
a) How do I take advantage of this?
This article does the best overall presentation of why you might
want to sell:

As you can see, it's not easy to safely make money out of a real
estate bubble without some sacrifices (moving or downsizing).
b) How long do I need to wait?
While stocks and other easy-to-sell assets have crashed quickly
and been over with, real estate is a bit trickier. Japan's
real estate boom took about 15-18 years. It's bust has been 15
years and counting. Waiting 30 years is great if you plan on
living 1000 years, but not so great for the rest of us.
There are a lot of reasons for housing to crash: foreclosures,
rising interest rates, panicked sellers. But again, detecting
the end of the bubble is hard.
c) So, when should I buy?
Buy when you can absolutely afford it (e.g. fixed rate mortage
that takes up 25-35% of your income). Buy when you can put down
a good down payment. Buy when the thought of this house dropping
another 10-20% in price doesn't bother you because you've got a
home.
For investing, buy when you can afford to take over the monthly
payments for as long as it takes you to find a new renter. More
than that and those monthly payments might start to hurt.
In the meantime, continuing to save will get you towards that goal.
I know this is a long article, but I hope it was worth the reading.
