It's also easy to lose 100% of your investment when you buy property with leverage. At least with a call option you can't lose more than your initial investment. You can with property, unless you live in a jurisdiction which cancels the outstanding loan on a property after it's repossessed by the lender.

Perhaps your point is that, with a property purchase, you can ignore short term price movements. As long as you have enough money to pay the mortgage each month, you get 100% exposure to the price increase over 25 years, even though you put only 10% down and borrowed the rest.

The volatility doesn't matter. If I buy a 1-year call option on a particular share, it doesn't matter if the price goes up and down every day during that year. What matters is the price at the time the option expires.

What _does_ matter, and this may have been what you were thinking, is that it's hard to buy a long term call option on an individual share. The longest you can buy easily is probably 2 years, which is much less than the length of a mortgage.
