We often hear about people betting their life savings of $100k on the next property of say $500k, hoping for that 20% rise before TOP and make $100k return (with a capital base of $100k). Lets see how this works in that matrix thingy we used in the previous post: Let's give the benefit of doubt and say this guy has 70% chance of making $100k, he has read the property market well, the cycle is turning, the stars are aligned. However, again in life, since nothing is 100% one, we have to think that he also has a 30% downside whereby he will lose $250k (ppty of $500k goes down by $100k, mortgage $130k, legal fees $20k all add up to $250k) Probability payoff 0.3 -250k -75k 0.7 100k 70k Expected return -5k Now we see that the expected return is negative. Even if we tweak the no.s here and there, which I did, the expected return is not high. You can probably get to expected return of $80k - which is good if you use $100k as the base.
