Part 1 of 4

Why a seller cares

An option gives somebody the right to buy at a set price for a set time, usually for a fee. Sellers meet it in lease-option deals and in offers from investors who want time before committing.

A simple example

A tenant pays $5,000 for a two-year option to buy at $250,000. For two years you cannot sell to anybody else at any price.

Option to purchase: a simple example
What the holder doesWhat follows
Buys inside the windowThe sale goes ahead at $250,000, whatever the market did
Lets the window passYou keep the $5,000 and are free to sell to anyone
Tries to buy after the windowNo right remains; it is a fresh negotiation

An option is time bought with money. The price is fixed, the decision is theirs.

Part 3 of 4

What people get wrong

That an option obliges the buyer. It is a right, not a promise; only the seller is bound during the window.
