As we said, property values tend to go up 7% a year, but in the first year there is a 30% chance your house goes down in value.

Over time the probability of losing money goes down.

In 20 years there is a 98% chance your house goes up in value to some degree.

Sure, on average property prices go up 7%, but that doesn’t happen every year. And there is still a small chance it doesn’t happen.

Probability and modelling helps you understand what might happen year to year.

That is a better level of decision-making.

The only drawback with this is that it takes a lot of number crunching, so this data is not always available.

Level #5 – Use a medium

This type of thinking says things like: “Oh mighty tea leaves, when will the market recover?”

This level is a joke. It’s suggesting the only way to gain a perfect understanding of what will happen in the future is to:

  1. talk to a medium
  2. become Marty McFly and go back to the future.

The point here is that you can’t perfectly know what will happen in property. We make decisions even though the future isn’t fully locked in or guaranteed.

The best we can do is understand the data and probabilities, then make the best decision we can.

How do I use this model to make a better decision?

My challenge to you, as an investor, is to move up the levels of decision-making.

If you find yourself worrying about a decision, look at the 5 levels. Identify which type of decision you’re making, then try to move up a level.

In this article, we’ve used the fear of house prices never rising, but another common fear for investors is that they’ll never get a tenant.

So, if you’re currently at level 1 (emotional decisions), move to level 2. Ask another investor about their experience getting tenants.

After that, look at the data (level 3). And then, if you can, see if you can get to that higher level of probability and modelling.

It’s about challenging your initial doubts and fears to see if you can move them into a more sophisticated way of problem-solving.
