So I thought this through more.
Every year there have been doomsday prophecies and people absolutely convinced about something. Some even have lots of data to back up their theory. Fact is, most never come to pass.
What I definitely learned in dealing stocks that you simply can't predict the market...you can only adapt to it. Sometimes prices continue to rise and you stare thinking 'no way! they're going plummet any day now!' but they continue to rise for months or years. At times prices fall drastically and it feels like the trend has reversed, but sure enough they recover the next day or week. All the while some sit there and not act (even when prices fall). The same situation happens on a down trend, where some refuse to (short) sell hoping for recovery, but only losing even more, yet others panic at a normal blip or spike, selling or buying too soon.
I am a believer of 'past performance statistically increases the odds of similar future performance.' Yes past performance IS an indicator of future performance. I buy stocks trending up assuming they will continue to do so rather than stocks tending down hoping they'll recover. After time, the trend will reverse and there is time to sell before too late. Another words... when real estate prices are rising is a good time to buy - not when they start falling.
Real estate is very location oriented, but I'd say as a whole its trending up now today. I don't think there are signs of a reversal yet. Real estate is very slow moving compared to stocks. Of course there could be some kind of drastic turn of the real estate market, but I don't think that the likelihood is any more today than yesterday. There is always risk and it is always accompanied by opportunity.
You never know where the bottom or top is, so you can't rely on a bubble bursting as an indicator of when to buy. So my current theory is today is still a good day to buy real estate and waiting around is pointless. Nonetheless, I think people should be careful being over leveraged or too tight on what is break even or making a profit. Traditionally, rents don't really move up and down much and I really doubt this would be a drastic change.
I think the most critical situation today is that there is a lower supply and higher demand in the real estate market now that the economy is doing well. Many more people today would rather rent than buy (young people don't want to get starter homes, but rather save up for the big one while living cheap). This trend is very different than in the past where unqualified people were handed mortgages with no down payment. So I don't see a crash or prices dropping in the near future, but rather it is a good opportunity to buy and in fact perhaps investors are the real winners in this situation.
