How Does a Property Chain Transaction Work When Buying and Selling a Property?

If you’re buying and selling a property at the same time, you will likely be part of a property chain — a sequence of dependent transactions where each sale funds the next purchase. Managing a chain can be complex, and understanding how the process works, including the release mechanism, can help ensure a smoother transaction.

What Is a Property Chain?

A property chain occurs when multiple home sales and purchases are linked together. This means:

You need to sell your current home to buy your new one.
Your buyer may also be selling their property to fund their purchase.
Your seller may also be buying another property, creating a chain of transactions.

Each transaction in the chain is dependent on the others, meaning delays in one part can affect everyone involved.

How Does the Process Work?

1. Instructing a Solicitor

Since you are both selling and buying, your solicitor (hopefully us!) will handle both transactions simultaneously, ensuring that legal documents and contracts are aligned to avoid gaps in the process.

2. Agreeing on Sale and Purchase Terms

Once you have accepted an offer on your property and had your offer accepted on a new home, the legal process begins. Your solicitor will:

Review contracts for both transactions.
Carry out property searches and due diligence.
Liaise with the other solicitors in the chain to ensure everything progresses smoothly.

3. The Release Mechanism in Chain Transactions

A crucial part of managing a chain transaction is ‘the release mechanism’, which helps coordinate the exchange of contracts across multiple transactions.

If you are in the middle of a chain, your solicitor will first seek confirmation from your buyer’s solicitor that they are ready to proceed.
Once assured, your solicitor will request a ‘release’ from the solicitor acting for the person selling to you.
This means you exchange contracts on your sale first, then your solicitor immediately returns to exchange on your purchase.
This process prevents situations where you exchange on your purchase but your sale has not been finalised—reducing the risk of financial exposure.

This mechanism ensures that all transactions exchange contracts in a coordinated manner, reducing uncertainty and keeping the chain moving.

4. Exchange of Contracts

Contracts are usually exchanged simultaneously for both your sale and purchase. At this point, the transaction becomes legally binding, meaning neither party can withdraw without penalties.

5. Completion Day

On the day of completion:

The sale proceeds from your buyer are received.
These funds are used to complete your purchase.
Once all payments have been made, you hand over the keys to your buyer and collect the keys to your new home.

Potential Challenges and How to Manage Them

Delays in the Chain – One party experiencing mortgage issues, legal delays, or survey concerns can slow down the entire process. Proactive communication between solicitors helps manage expectations.
Breakdowns in the Chain – If a buyer or seller pulls out, the whole chain can collapse. Some buyers/sellers choose to move into temporary accommodation if they need to proceed with their sale but their purchase is delayed.
Same-Day Exchange and Completion – To avoid risks, some chains opt to exchange and complete on the same day, but this requires all parties to be prepared, which can be stressful.
