What is an Option To Purchase?
An option to purchase is a clause in a contract that gives one party the exclusive right — but not the obligation — to buy a property within a specified time frame and at agreed-upon terms.
Why Option To Purchases Matter in Real Estate
In Canadian real estate, options to purchase are common in lease-to-own and commercial transactions. The buyer pays an option fee for the exclusive right to purchase the property in the future. This right is not transferable and typically expires if not exercised by a set date.Option agreements typically include:
- Purchase price or pricing formula
- Duration of the option period
- Non-refundable option fee
- Terms under which the option can be exercised
Understanding the option to purchase helps buyers structure flexible agreements and evaluate their rights before committing to full ownership.
Example of an Option To Purchase
A commercial tenant signs a five-year lease with an option to purchase the building at $950,000. They have the right to buy anytime during the lease term by providing written notice.
