Little known perhaps is that the IRS has for some time considered longer than 3 yr options, like Ron LeGrand's 5-10yr options to be taxable events as if it's an installment sale.

Curt,

That is not entirely true. Much of it depends upon structure. You run into big issues if the option is split into them making higher payments.
