From the Real Estate Put Options example provided here, let us assume that a homeowner lives in La Jolla, CA and the derived value of the property on January 1st, 2008 at $1m.
Considering a historical rate for San Diego real estate returns, assume that the property value will decline to, say $0.8m in 5 years.
We use binominal pricing and historical price volatility. Below are four Real Estate Put Options scenarios, which differ by strike price.
Let’s review Option 1
The property is valued on Jan 1st, 2008 at $1m. The term of the put option is 5 years with a strike price of $0.7m.
The investor receives $0.31 per share today. The property value derived on Jan 1st, 2013 is $0.8m. The derived value is above the strike price of $0.7m and, therefore, investor payment is $0.
This option is “out the money.” Options 1 and 2 are “out of the money.”
In contrast, let’s review Option 3
The property is valued on Jan 1st, 2008 at $1m. The term of the put option is 5 years with a strike price of $0.9m. The investor receives $12 per share today.
The property value derived on Jan 1st, 2013 is $0.8m. Option payoff is the difference between the strike price $0.9m and the price in year 5 of $0.8m which is $100,000 or $100 per share, therefore, investor payment is $100 per share owned. Options 3 and 4 are “in the money.”
