In the property market, an option agreement is a legal contract giving one party (usually the buyer) the exclusive right to purchase property at a specified price within a particular time frame. While these agreements are commonly used in property development, they offer flexibility and security to both buyers and sellers, allowing for a well-structured transaction without immediate commitment. In this article we’ll dive into what an option agreement entails, the types of option agreements and how they benefit both parties.

What is an Option Agreement?
An option agreement allows a buyer the right, but not the obligation, to purchase a property within a predetermined period. During this time, the seller cannot sell the property to anyone else. In exchange for this right, the buyer usually pays a non-refundable option fee, which is often deducted from the purchase price if the option is exercised. The option holder is under no obligation to go through with the purchase, providing the buyer with a significant amount of flexibility.
For example, a developer may want to secure land to build a housing estate but needs time to obtain planning permissions. An option agreement lets them secure the right to purchase the land without committing until the permissions are in place.
Key Components of an Option Agreement
Option Fee: This is the non-refundable payment made by the buyer to the seller, essentially paying for the exclusivity of the purchase right.
Option Period: The time frame within which the buyer can decide whether to proceed with the purchase. This is often a lengthy period, allowing for tasks like securing planning permission or financing.
Purchase Price: The price at which the property will be sold if the buyer exercises the option. This is typically agreed upon at the start of the agreement, though some agreements may allow for adjustment based on market conditions.
Conditions for Exercise: The buyer may have specific conditions they need to meet before they can exercise the option, such as securing planning approval or arranging finance.
Termination: If the buyer does not exercise the option within the agreed timeframe, the option expires and the seller can sell the property to another party.

Benefits of an Option Agreement
For buyers, an option agreement provides the flexibility to conduct due diligence and secure necessary planning permissions, or finance before committing to a purchase. This reduces the financial risk involved in large transactions, particularly in property development.
For sellers, although they agree to remove the property from the market for the option period, they receive the option fee upfront, which compensates them for the exclusivity. Additionally, sellers may benefit from overage agreements, which allow them to share in any future increase in the property’s value after development.
Types of Option Agreements
- Straight Option: This is the most commonly used type, giving the buyer the right to purchase the property within a specified period and price.
- Put Option: This less common type gives the seller the right to compel the buyer to purchase the property within the option period. It provides sellers with greater security if they want to ensure a sale.
- Call Option: A more specific type of option where the buyer can purchase the property, but the seller is not obligated unless the buyer exercises the option.
- Purchase Option Agreement: This is a specialised form of a call option, often used in property development deals where the buyer needs time to arrange planning permissions or financial backing before deciding whether to purchase. A purchase option agreement can be a powerful tool for developers, allowing them to tie up valuable property for future projects without committing until they’re ready.
Risks Associated with Option Agreements
Although option agreements are beneficial, they also come with risks:
For Buyers: If a buyer decides not to exercise the option, they lose the non-refundable option fee. Additionally, buyers often spend money on securing planning permission or conducting due diligence, which can be costly if the purchase doesn’t go through.
For Sellers: The risk of tying up their property for a prolonged period, only to have the buyer walk away. This can be especially risky in a volatile market where property values could increase during the option period, potentially leaving the seller at a disadvantage if the agreed price is lower than the current market rate.
Overage Agreements
An overage agreement is a common clause that may be included with an option agreement, particularly in property development deals. This allows the seller to benefit from any future uplift in the value of the property after the sale, typically if the buyer gains planning permission or develops the land. For example, if a developer buys a property for a lower price, secures planning permission and then sells it for a profit, the seller may be entitled to a share of that profit under an overage agreement.
Application of Option Agreements in Property Development
Option agreements are most commonly used in land development deals, where a developer wants to secure a parcel of land while seeking planning permissions or environmental assessments. In these cases, the buyer needs time to ensure that the development project is feasible before committing to purchase the land.
In the residential property market, option agreements allow developers or buyers to secure properties without upfront commitment, making it easier to lock in a good deal while obtaining financing or resolving other issues.
In commercial property, option agreements can also be used to secure office buildings, shopping centres, or other large-scale projects, where the buyer may need more time to assess the viability of the deal before making a final decision.
How to Structure an Option Agreement
When structuring an option agreement, it’s essential to consider:
Option Period: How long will the option period last? It should be long enough for the buyer to conduct due diligence but not so long that the seller is tied up indefinitely.
Option Fee: The fee should reflect the exclusivity of the arrangement, balancing compensation for the seller and affordability for the buyer.
Conditions for Exercise: The agreement should clearly define under what conditions the option can be exercised, such as planning permission or financial arrangements.
Overage Clauses: These should be included if there is a possibility that the property’s value could increase significantly post-sale. The overage agreement should be carefully drafted to ensure both parties understand how any uplift will be shared.
Option Agreements as a Strategic Tool
In the property market, option agreements provide a strategic tool for both buyers and sellers, offering flexibility, reduced risk and opportunities for profitable development deals. Buyers can secure property interests without committing to a full purchase until they are confident that the transaction will be feasible, while sellers benefit from the upfront option fee and potentially future profits through overage agreements.
When dealing with the intricacies of an option agreement, it’s always a good idea to consult with legal professionals or experienced brokers who specialise in property deals. They can offer valuable guidance and help ensure your interests are fully protected, whether you’re on the buying or selling side of the transaction.
By understanding and effectively structuring an option agreement, you can secure profitable deals, minimise risks and capitalise on future development opportunities.
