Reading Howard Marks' investment memos is up there with reading Paul Graham's essays. You just need to do it. Howard's latest is about "taking the temperature" of the market and I think you'll find the lessons invaluable for everything from equities to residential real estate.

Here's an excerpt that I liked:

We don’t say, “It’s cheap today, but it’ll be cheaper in six months, so we’ll wait.” If it’s cheap, we buy. If it gets cheaper and we conclude the thesis is still intact, we buy more. We’re much more afraid of missing a bargain-priced opportunity than we are of starting to buy a good thing too early. No one really knows whether something will get cheaper in the days and weeks ahead – that’s a matter of predicting investor psychology, which is somewhere between challenging and impossible. We feel we’re much more likely to correctly gauge the value of individual assets.

These are investing words to live by. Avoid your own emotionality and value the asset. If it's not cheap, don't buy it. If it's cheap, buy it. Then take a long-term view. It all sounds simple enough, but it's clearly not so easy. And that's why we have extreme highs and extreme lows in the market.

Eighteen months ago, everyone wanted to buy residential real estate. Today, prices are lower, but fewer people want to buy residential real estate. Part of this is obviously because of interest rates. But part of it is also just because of emotion.
