What happens to my mortgage when the house sale completes?

At completion, the mortgage secured against the property is normally brought to an end as part of the conveyancing process. The lender’s charge is dealt with so the buyer can receive the property with the agreed title, subject to any arrangements made to transfer or replace your borrowing.

Before completion, your conveyancing solicitor requests a formal redemption statement from the mortgage lender. This confirms the amount needed to settle the account on the expected completion date. It may include interest calculated up to that date, administration charges, an early repayment charge, and any other sums recorded on the account. Redemption statements usually have a validity period, so your solicitor may need an updated figure if the completion date changes.

The completion statement prepared by your solicitor shows how the sale money is allocated. It normally records:

• the sale price received;
• the amount required by the mortgage lender;
• conveyancing and other agreed transaction costs;
• any additional payments required to complete the transfer; and
• the balance due to you or any amount that needs further funding.

On completion, the buyer’s conveyancer transfers the purchase funds to your solicitor. Your solicitor then follows the completion instructions and the lender’s redemption requirements. Once the lender has received the required amount, it updates the mortgage account and provides the information needed to release its legal charge over the property. This allows the buyer’s solicitor to register the buyer’s ownership without your old mortgage continuing against the property.

Completion does not necessarily mean every administrative task is finished immediately. Your solicitor may still need to send post-completion documents, deal with the discharge of the lender’s charge and account to you for the final balance. The Land Registry record may take longer to update, but the contractual sale itself has completed on the agreed completion date.

Check the final figures carefully. Compare the redemption figure and completion statement with your latest mortgage information. Ask your solicitor to explain any difference, particularly if the completion date moved, an early repayment charge applies, or the lender added interest or another account adjustment. Keep copies of the completion statement, lender correspondence and evidence of the final account position.

Your regular mortgage payment may still be collected if the direct debit falls close to completion. Do not cancel it without checking with the lender or solicitor, because the account may not yet show as settled and an additional payment could be needed. If a payment is taken after redemption, contact the lender to ask how it will be treated and whether any surplus will be returned.

If you are buying another property, the existing mortgage may not simply disappear in the same way. You may be able to port the borrowing to the new property, subject to the lender’s criteria and a separate assessment, or arrange replacement finance. The lender and conveyancing solicitor should confirm whether the old account is being fully redeemed, transferred or replaced, and how any early repayment charge is handled.

After completion, contact the lender if you need written confirmation that the mortgage balance is zero and the charge has been released. Also review linked products, such as payment protection or insurance arranged separately from the mortgage, because these may not be cancelled automatically when the property loan ends.

Where the sale relates to a joint mortgage, both borrowers should check the lender’s final statement and any correspondence about closure. Where there is a second charge, secured loan or other borrowing registered against the property, that debt must also be identified and dealt with through the conveyancing process rather than assuming the main mortgage settlement covers it.
